    We report the updated classification of primary immunodeficiencies compiled by the Primary Immunodeficiency Expert Committee (PID EC) of the International Union of Immunological Societies (IUIS). In the two years since the previous version, 34 new gene defects are reported in this updated version. For each disorder, the key clinical and laboratory features are provided. In this new version we continue to see the increasing overlap between immunodeficiency, as manifested by infection and/or malignancy, and immune dysregulation, as manifested by auto-inflammation, auto-immunity, and/or allergy. There is also an increased number of genetic defects that lead to susceptibility to specific organisms which reflects the finely tuned nature of immune defense systems. This classification is the most up to date catalogue of all known and published primary immunodeficiencies and acts as a current reference of the knowledge of these conditions and is an important aid for the genetic and molecular diagnosis of patients with these rare diseases.

    The number of genetically defined Primary Immunodeficiency Diseases (PID) has increased exponentially, especially in the past decade. The biennial classification published by the IUIS PID expert committee is therefore quickly expanding, providing valuable information regarding the disease-causing genotypes, the immunological anomalies, and the associated clinical features of PIDs. These are grouped in eight, somewhat overlapping, categories of immune dysfunction. However, based on this immunological classification, the diagnosis of a specific PID from the clinician's observation of an individual clinical and/or immunological phenotype remains difficult, especially for non-PID specialists. The purpose of this work is to suggest a phenotypic classification that forms the basis for diagnostic trees, leading the physician to particular groups of PIDs, starting from clinical features and combining routine immunological investigations along the way. We present 8 colored diagnostic figures that correspond to the 8 PID groups in the IUIS Classification, including all the PIDs cited in the 2011 update of the IUIS classification and most of those reported since.

    As in other regions, the incidence of atopic dermatitis in Latin America has been increasing in recent years. Although there are several clinical guidelines, many of their recommendations cannot be universal since they depend on the characteristics of each region. Thus, we decided to create a consensus guideline on atopic dermatitis applicable in Latin America and other tropical regions, taking into account socio-economic, geographical, cultural and health care system characteristics. The Latin American Society of Allergy Asthma and Immunology (SLAAI) conducted a systematic search for articles related to the pathophysiology, diagnosis and treatment of dermatitis using various electronic resources such as Google, Pubmed, EMBASE (Ovid) and Cochrane data base. We have also looked for all published articles in Latin America on the subject using LILACS (Latin American and Caribbean Literature on Health Sciences) database. Each section was reviewed by at least two members of the committee, and the final version was subsequently approved by all of them, using the Delphi methodology for consensus building. Afterward, the final document was shared for external evaluation with physicians, specialists (allergists, dermatologists and pediatricians), patients and academic institutions such as universities and scientific societies related to the topic. All recommendations made by these groups were taken into account for the final drafting of the document. There are few original studies conducted in Latin America about dermatitis; however, we were able to create a practical guideline for Latin America taking into account the particularities of the region. Moreover, the integral management was highlighted including many of the recommendations from different participants in the health care of this disease (patients, families, primary care physicians and specialists). This practical guide presents a concise approach to the diagnosis and management of atopic dermatitis that can be

    This guideline advises on the management of patients with egg allergy. Most commonly, egg allergy presents in infancy, with a prevalence of approximately 2% in children and 0.1% in adults. A clear clinical history and the detection of egg white-specific IgE (by skin prick test or serum assay) will confirm the diagnosis in most cases. Egg avoidance advice is the cornerstone of management. Egg allergy often resolves and re-introduction can be achieved at home if reactions have been mild and there is no asthma. Patients with a history of severe reactions or asthma should have reintroduction guided by a specialist. All children with egg allergy should receive measles, mumps and rubella (MMR) vaccination. Influenza and yellow fever vaccines should only be considered in egg-allergic patients under the guidance of an allergy specialist. This guideline was prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI) and is intended for allergists and others with a special interest in allergy. The recommendations are evidence-based but where evidence was lacking consensus was reached by the panel of specialists on the committee. The document encompasses epidemiology, risk factors, diagnosis, treatment, prognosis and co-morbid associations.

    The advent of intracytoplasmic sperm injection (ICSI) has contributed to a significant growth in the delivery of assisted conception technique, such that IVF/ICSI procedures are now recommended over other interventions. Even the UK National Institute for Health Care Excellence (NICE) guidelines controversially recommends against intrauterine insemination (IUI) procedures in favour of IVF. We reflect on some of the clinical, economic, financial and ethical realities that have been used to selectively promote IVF over IUI, which is less intrusive and more patient friendly, obviates the need for embryo storage and has a global application. The evidence strongly favours IUI over IVF in selected couples and national funding strategies should include IUI treatment options. IUI, practised optimally as a first line treatment in up to six cycles, would also ease the pressures on public funds to allow the provision of up to three IVF cycles for couple who need it. Fertility clinics should also strive towards ISO15189 accreditation standards for basic semen diagnosis for male infertility used to triage ICSI treatment, to reduce the over-diagnosis of severe male factor infertility. Importantly, there is a need to develop global guidelines on inclusion policies for IVF/ICSI procedures. These suggestions are an ethically sound basis for constructing the provision of publicly funded fertility treatments.

    The objective of this study was to determine if characteristics of sperm motion determined by computer-aided semen analysis (CASA) after thawing and preparation on discontinuous gradient could predict pregnancy outcome after intrauterine insemination (IUI) from frozen donor sperm. A retrospective analysis of 100 non-selected women undergoing 171 consecutive donor insemination cycles was conducted between January 2006 and April 2007. Semen samples from all donors were analysed after thawing and density gradient preparation. Women who became pregnant and those who did not were comparable in terms of age, ovarian stimulation regimen and indication of IUI with donor semen. Pregnancy rate per cycle was 21.8%, and pregnancy occurred after 2.5 IUI cycles on average. Motility parameters of sperm measured by CASA (VAP, VCL, VSL, LIN, STR, and ALH) and total spermatozoa concentration after preparation on discontinuous gradient showed no difference in both groups. Progressive and total motile spermatozoa concentration, as well as progressive and total motile percentages was significantly higher in pregnancy group. The receiver operating characteristic (ROC) curve analysis showed that total motile percentage >17% and motile concentration >0.9 x 10(6)/mL best predicted pregnancy. In a multivariate analysis, only total motility percentage was able to predict pregnancy. Sperm motility parameters of frozen-thawed prepared donor sperm obtained by CASA do not seem to predict pregnancy in IUI cycles. Total motile and progressive percentages and concentrations remain the best prognostic elements for pregnancy in IUI with donor semen.

    Background: The aim of this study, we have compared the advantages of oral dydrogestrone with vaginal progesterone (cyclogest) for luteal support in intrauterine insemination (IUI) cycles. Progesterone supplementation is the first line treatment when luteal phase deficiency (LPD) can reasonably be assumed. Objective: This study was conduct to compare the effect of oral dydrogestrone with vaginal Cyclogest on luteal phase support in the IUI cycles. Materials and Methods: This prospective, randomized, double blind study was performed in a local infertility center from May 2013 to May 2014. It consisted of 150 infertile women younger than35years old undergoing ovarian stimulation for IUI cycles. They underwent ovarian stimulation with oral dydrogesterone (20 mg) as group A and vaginal cyclogest (400 mg) as group B in preparation for the IUI cycles. Clinical pregnancy and abortion rates, mid luteal progesterone (7daysafter IUI) and patient satisfaction were compared between two groups. Results: The mean serum progesterone levels was significantly higher in group A in comparison with group B (p=0.001). Pregnancy rates in group A was not statistically different in comparison with group B (p =0.58). Abortion rate in two groups was not statistically different (p =0.056) although rate of abortion was higher in group B in comparison with A group. Satisfaction rates were significantly higher in group A compared to group B (p<0.001). Conclusion: We concluded that oral dydrogestrone is effective as vaginal progesterone for luteal-phase support in woman undergoing IUI cycles. Moreover, the mean serum progesterone levels and satisfaction rates in dydrogestrone group were higher than cyclogest group. PMID:26494991

    Many variables may influence success rates after intrauterine insemination (IUI), including sperm quality in the native and washed semen sample. A literature search was performed to investigate the threshold levels of sperm parameters above which IUI pregnancy outcome is significantly improved and/or the cut-off values reaching substantial discriminative performance in an IUI programme. A search of MEDLINE, EMBASE and Cochrane Library revealed a total of 983 papers. Only 55 studies (5.6%) fulfilled the inclusion criteria and these papers were analysed. Sperm parameters most frequently examined were: (i) inseminating motile count after washing: cut-off value between 0.8 and 5 million; (ii) sperm morphology using strict criteria: cut-off value ⩾5% normal morphology; (iii) total motile sperm count in the native sperm sample: cut-off value of 5-10 million; and (iv) total motility in the native sperm sample: threshold value of 30%. The results indicate a lack of prospective studies, a lack of standardization in semen testing methodology and a huge heterogeneity of patient groups and IUI treatment strategies. More prospective cohort trials and prospective randomized trials investigating the predictive value of semen parameters on IUI outcome are urgently needed. It is generally believed that intrauterine insemination (IUI) with homologous semen should be a first-choice treatment to more invasive and expensive techniques of assisted reproduction in cases of cervical, unexplained and moderate male factor subfertility. The rationale for the use of artificial insemination is to increase gamete density at the site of fertilization. Scientific validation of this strategy is difficult because literature is rather confusing and inconclusive. Many variables may influence success rates after IUI treatment procedures. It seems logical that sperm quality has to be one of the main determinants to predict IUI success. Clinical practice would benefit from the establishment of

    The author presents the fundamental principles of the immunological process, and describes the constitution, origin, classification and action of antibodies and antigens. He identifies the 5 types of antibodies. He then comments on the classical mechanism of the immunological response. The immunological process is then related to a couple's infertility. After a short history the author calls attention to immunological problems of semen and describes a test he created to detect agglutination and/or immobilization of spermatozoa in non-diluted female blood serum. It is a test to be used as a first step in the research of infertility without an apparent cause (ESCA) in office practice. The author also presents the results of 182 cases studied and in his commentary he shows the advantages and deficiencies of the test.

    The aim was to investigate the influence of various biological factors upon the outcome of intrauterine insemination (IUI). The total IUI history (856 cycles) of 352 couples was studied. Live-birth showed a strong negative correlation with female age but no correlation with male age. Antimüllerian hormone (AMH) and antral follicle count (AFC) correlated negatively with female age, and follicle stimulating hormone (FSH) correlated positively. Significant thresholds were found for all three variables, and also for total motile count (TMC) in the prepared sperm. Calculating pregnancy losses per positive pregnancy showed a strong correlation with increasing female age. This was highly significant for biochemical losses but not for fetal heart miscarriages. Male age had no effect on rate of pregnancy loss. In conclusion, female age, FSH, AMH and TMC are good predictive factors for live-birth and therefore relate to essential in vivo steps in the reproductive process. PMID:24127958

    Much research has been done to investigate why the fetus in most pregnancies, in spite of being semi-allogenic, is not rejected by the immune system. Experiments in transgenic mice have suggested that dysfunctions in both the innate immune system (NK cells) and the adaptive immune system (T-cells and T regulatory cells) result in increased fetal loss rate. Many studies have suggested that women with pathological pregnancies such as recurrent miscarriages have signs of generally exaggerated inflammatory immune responses both before and during pregnancy and signs of breakage of tolerance to autoantigens and fetal antigens. In addition, several abnormalities of innate immune responses seem to characterize women with pathological pregnancies. These abnormalities involve disadvantageous interactions between uterine NK cells and HLA-G and HLA-C on the trophoblast that may have pro-inflammatory effects. Also, humoral factors belonging to the innate immune system such as mannose-binding lectin seem to be associated with pregnancy outcome probably by modifying the level of inflammation at the feto-maternal interface. The pro-inflammatory conditions at the feto-maternal interface characterizing pathological pregnancy are suggested to predispose to adaptive immunological processes against alloantigens on the trophoblast that may further increase the risk of pathological pregnancy outcome. The best documented adaptive immune reaction against fetal alloantigens is directed against male-specific minor histocompatibility (HY) antigens. Anti-HY immunity seems to play a role especially in women with secondary recurrent miscarriage.

    Allergic diseases constitute a significant health problem in Turkey. According to a recent multicenter study, which used the ISAAC questionnaire, the mean prevalence of wheezing, rhinoconjunctivitis, and eczema in 10-yr-old school children during the past year was 15.8%, 23.5%, and 8.1%, respectively. A healthcare level system, regulated by Ministry of Health, is available in Turkey. Pediatric allergists and pediatric immunologists provide patient care at the tertiary level. Currently, 48 centers deliver care for allergic and immunologic diseases in children. There are 136 pediatric and 61 adult allergists/immunologists. Although the number of allergy/clinical immunology specialists is limited, these centers are capable of delivering many of the procedures required for the proper management and diagnosis of allergy/immunology. Pediatric allergy and/or immunology is a subspecialty lasting 3 yr and follows a 4-yr pediatric specialist training. Fellow training involves gaining knowledge in basic and clinical allergy and immunology as well as the performance and interpretation of laboratory procedures in the field of allergy and clinical immunology. The Turkish National Society of Allergy and Clinical Immunology (TNSACI) was officially established in 1989 and currently has 356 members. The society organizes a national congress annually and winter schools for fellowship training as well as training courses for patients and their relatives. TNSACI also has a strong representation in European Academy of Allergy and Clinical Immunology (EAACI) and European Society for Immunodeficiencies (ESID) through its participation in the executive committee, consensus reports, and initiatives in the diagnosis of allergic and immunologic diseases of children. The 30th Congress of the EAACI is also due to be held in Istanbul, Turkey, between June 11 and 15, 2011.

    Objective The aim of the present retrospective study was to evaluate intrauterine insemination (IUI) clinical experiences and to define the variables for predicting success. Material and Methods The present study was an observational trial performed in a private IVF center on subfertile couples who had applied for treatment between 2002 and 2012, in which the data of 503 IUI cases were retrospectively reviewed. Couples who had been diagnosed with unexplained and mild male subfertility were included. The primary outcome measure was the clinical pregnancy rate in an attempt to form a predictive model for the odds of a clinical pregnancy. Recorded parameters were used to determine the prediction model. Results Utilizing univariate logistic regression analysis, clinical pregnancy was positively associated with the duration of infertility (OR=1.09, p=0.089), secondary infertility (OR=1.77, p=0.050), and +4 sperm motility after preparation (OR=1.03, p=0.091). Following an adjustment analysis involving a multivariate logistic regression, clinical pregnancy was still found to positively associate with secondary infertility (OR=2.51, p=0.008). Conclusion IUI success in secondary infertile couples who were in the unexplained infertility and mild male subfertility groups was higher than that in primary infertile couples, and the chances of pregnancy increased as sperm numbers with +4 motility increased. It is difficult to concomitantly evaluate all these parameters and to determine a predictive parameter in IUI independent from other factors.

Today, the teaching-learning process in such areas has been improved with tools such as educational software. This article introduces "Virtual Immunology," a software program available free of charge in Portuguese and English, which can be used by teachers and students in physiology, immunology, and cellular biology classes. We discuss the development of the initial two modules: "Organs and Lymphoid Tissues" and "Inflammation" and the use of interactive activities to provide microscopic and macroscopic understanding in immunology. Students, both graduate and undergraduate, were questioned along with university level professors about the quality of the software and intuitiveness of use, facility of navigation, and aesthetic organization using a Likert scale. An overwhelmingly satisfactory result was obtained with both students and immunology teachers. Programs such as "Virtual Immunology" are offering more interactive, multimedia approaches to complex scientific principles that increase student motivation, interest, and comprehension.

    Polycystic ovary syndrome is a common heterogeneous endocrine disorder in reproductive-age women, with prevalence around 4-12%. The present study was performed to investigate whether progesterone-induced endometrial bleed before ovulation induction affects pregnancy in patients with PCOS who underwent intrauterine insemination (IUI) treatment. A total of 241 IUI cycles were retrospectively analyzed. Patients enrolled in this study underwent ovulation induction with IUI treatment from Jan. 2011 to Dec. 2012. The study group consisted of 184 cycles with progesterone-withdrawal bleed before ovulation induction. The control group included 57 cycles with spontaneous menses. The clinical characteristics, ovulation induction parameters and IUI outcomes, such as pregnancy rate and live birth/ongoing pregnancy rate, were compared between the two groups. We found that patients in induced shedding group had thinner peak endometrium in ovulation induction cycles. Additionally, the ratio of peak endometrial-thickness to baseline endometrial-thickness was lower in induced menses patients. However, the pregnancy rate and live birth/ongoing pregnancy rate per cycle were similar with the control group. Excluding the peak E2 level, peak E2/number of follicles > 15mm and peak endometrial-thickness/baseline endometrial-thickness, no differences were found in ovulation induction or IUI results between patients used Letrozole or Clomiphene Citrate. In patients undergoing administration with Letrozole, those taking progesterone had thinner endometrium and lower peak endometrial-thickness/baseline endometrial-thickness. However, the pregnancy rate and live birth/ongoing pregnancy rate were not statistically different from patients with spontaneous menses. In conclusion, our study showed that progesterone exerted a negative effect on endometrial development, which seemed to be associated with reduced pregnancy results in ovulation induction with IUI cycles.

  7. Replacing IUI with IVF for initial treatment of unexplained infertility: why this NICE recommendation is cause for concern.

    Woodward, Bryan; Tomlinson, Mathew; Kirkman-Brown, Jackson

    2016-06-01

    The latest guidelines from the National Institute for Health and Care Excellence (NICE) for assisted conception recommend that people experiencing unexplained infertility should no longer be offered stimulated intra-uterine insemination (IUI) as a first-line treatment, but rather be directed towards IVF or alternatively be left to expectant management. NICE has acknowledged that the cited evidence leading to this decision was not sufficiently robust. As such, we are concerned that accordance with these new NICE guidelines may result in people with no identifiable cause of their infertility being prematurely referred for IVF treatment. Since IVF constitutes a more invasive and expensive treatment process, which also represents an additional and unnecessary cost pressure to the National Health Service, there is a longstanding need for a robust clinical trial to resolve the uncertainty as to whether one treatment is more appropriate than another. Until such data is available, we suggest that provision of stimulated IUI, in centres achieving a satisfactory live birth rate, represents a significant cost-saving to those commissioning fertility services, with lower risks to people treated.

    The broad immunologic roles of autophagy span innate and adaptive immunity and are often manifested in inflammatory diseases. The immune effects of autophagy partially overlap with its roles in metabolism and cytoplasmic quality control but typically expand further afield to encompass unique immunologic adaptations. One of the best-appreciated manifestations of autophagy is protection against microbial invasion, but this is by no means limited to direct elimination of intracellular pathogens and includes a stratified array of nearly all principal immunologic processes. This Review summarizes the broad immunologic roles of autophagy. Furthermore, it uses the autophagic control of Mycobacterium tuberculosis as a paradigm to illustrate the breadth and complexity of the immune effects of autophagy. PMID:25654553

    The purpose of this paper is to show that immunological memory is an associative and robust memory that belongs to the class of sparse distributed memories. This class of memories derives its associative and robust nature by sparsely sampling the input space and distributing the data among many independent agents. Other members of this class include a model of the cerebellar cortex and Sparse Distributed Memory (SDM). First we present a simplified account of the immune response and immunological memory. Next we present SDM, and then we show the correlations between immunological memory and SDM. Finally, we show how associative recall in the immune response can be both beneficial and detrimental to the fitness of an individual.

    Progress in immunology continues to grow exponentially every year. New applications of this knowledge are being developed for a broad range of clinical conditions. Conversely, the study of primary and secondary immunodeficiencies is helping to elucidate the intricate mechanisms of the immune system. We have selected a few of the most significant contributions to the fields of basic and clinical immunology published between October 2001 and October 2002. Our choice of topics in basic immunology included the description of T-bet as a determinant factor for T(H)1 differentiation, the role of the activation-induced cytosine deaminase gene in B-cell development, the characterization of CD4(+)CD25(+) regulatory T cells, and the use of dynamic imaging to study MHC class II transport and T-cell and dendritic cell membrane interactions. Articles related to clinical immunology that were selected for review include the description of immunodeficiency caused by caspase 8 deficiency; a case series report on X-linked agammaglobulinemia; the mechanism of action, efficacy, and complications of intravenous immunoglobulin; mechanisms of autoimmunity diseases; and advances in HIV pathogenesis and vaccine development. We also reviewed two articles that explore the possible alterations of the immune system caused by spaceflights, a new field with increasing importance as human space expeditions become a reality in the 21st century.

  13. Immunology's theories of cognition.

    PubMed

    Tauber, Alfred I

    2013-01-01

    Contemporary immunology has established its fundamental theory as a biological expression of personal identity, wherein the "immune self" is defended by the immune system. Protection of this agent putatively requires a cognitive capacity by which the self and the foreign are perceived and thereby discriminated; from such information, discernment of the environment is achieved and activation of pathways leading to an immune response may be initiated. This so-called cognitive paradigm embeds such functions as "perception," "recognition," "learning," and "memory" to characterize immune processes, but the conceptual character of such functions has meanings that vary with the particular theory adopted. When different formulations of cognition are considered, immunology's conceptual infrastructure shifts: Extensions of conventional psychological understanding of representational cognition based on a subject-object dichotomy support notions of immune agency; alternatively, formulations of perception that dispense with representations and attendant notions of agency reconfigure the predicate epistemology dominating current immune theory. Reviewing immunological literature of the past five decades, these two understandings of perception--representational and non-representational (considered here from ecological, enactivist, and autopoietic perspectives)--offer competing views of immune cognitive functions. These, in turn, provide competing philosophical understandings of immunology's conceptual foundations, which reflect parallel controversies dominating current debates in philosophy of mind and attendant discussions about personal identity.

    HIV Molecular Immunology is a companion volume to HIV Sequence Compendium. This publication, the 2014 edition, is the PDF version of the web-based HIV Immunology Database (http://www.hiv.lanl.gov/content/immunology/). The web interface for this relational database has many search options, as well as interactive tools to help immunologists design reagents and interpret their results. In the HIV Immunology Database, HIV-specific B-cell and T-cell responses are summarized and annotated. Immunological responses are divided into three parts, CTL, T helper, and antibody. Within these parts, defined epitopes are organized by protein and binding sites within each protein, moving from left to right through the coding regions spanning the HIV genome. We include human responses to natural HIV infections, as well as vaccine studies in a range of animal models and human trials. Responses that are not specifically defined, such as responses to whole proteins or monoclonal antibody responses to discontinuous epitopes, are summarized at the end of each protein section. Studies describing general HIV responses to the virus, but not to any specific protein, are included at the end of each part. The annotation includes information such as crossreactivity, escape mutations, antibody sequence, TCR usage, functional domains that overlap with an epitope, immune response associations with rates of progression and therapy, and how specific epitopes were experimentally defined. Basic information such as HLA specificities for T-cell epitopes, isotypes of monoclonal antibodies, and epitope sequences are included whenever possible. All studies that we can find that incorporate the use of a specific monoclonal antibody are included in the entry for that antibody. A single T-cell epitope can have multiple entries, generally one entry per study. Finally, maps of all defined linear epitopes relative to the HXB2 reference proteins are provided.

    Introduction: Male infertility factor is defined if the total number of motile spermatozoa (TMSC) < 20 × 106/ejaculated, and unexplained infertility if spermiogram is normal with normal female factor. The aim: of this study was to determine the predictive value of TMSC for spontaneous pregnancy (ST) and pregnancy after treatment with intrauterine insemination (IUI) in couples with male factor and unexplained infertility. What is known already: According to the WHO qualification system abnormal spermiogram can be diagnosed as oligozoospermia (O), asthenozoospermia (A), teratozoospermia (T) or combination (O+A+T) and azoospermia (A). Although this classification indicates the accuracy of findings its relevance for prognosis in infertile couple and the choice of treatment is questionable. Materials and Methods: The study included 98 couples with male infertility factor (bad spermiogram) and couples with normospermia and normal female factor (unexplained infertility). Testing group is randomized at: group (A) with TMSC> 3,106 / ejaculate and a spontaneous pregnancy, group (B) with TMSCl <3 x 106 / ejaculate and pregnancy after IUI, plus couples who have not achieved SP with TMSC> 3 x 106 / ejaculate and couples who have not achieved pregnancy. Main results: From a total of 98 pairs of men’s and unexplained infertility, 42 of them (42.8%) achieved spontaneous pregnancy, while 56 (57.2%) pairs did not achieve spontaneous pregnancy. TMSC was significantly higher (42.4 ± 28.4 vs. 26.2 ± 24, p <0.05) in the group A compared to group B. Couples with TMSC 1-5 × 106 ejaculate had significantly lower (9.8% vs. 22.2%, p <0.0001) rate of spontaneous pregnancy in comparison to couples after IUI treatment. Couples with unexplained infertility had significantly higher (56.8% vs. 29.9%, p <0.01) spontaneous pregnancy rate compared to couples after IUI treatment. Infertile couples had significant pregnancy rate with TMSC 5-10 x 106 / ejaculate (OR = 1.45, 95% CI:1.26-1.78, <0

    The hematology and immunology program conducted in support of the Apollo missions was designed to acquire specific laboratory data relative to the assessment of the health status of the astronauts prior to their commitment to space flight. A second objective was to detect and identify any alterations in the normal functions of the immunohematologic systems which could be attributed to space flight exposure, and to evaluate the significance of these changes relative to man's continuing participation in space flight missions. Specific changes observed during the Gemini Program formed the basis for the major portion of the hematology-immunology test schedule. Additional measurements were included when their contribution to the overall interpretation of the flight data base became apparent.

    Evidence from both human and rodent studies has indicated that alterations in immunological parameters occur after space flight. The number of flight experiments has been small, and the full breadth of immunological alterations occurring after space flight remains to be established. Among the major effects on immune responses after space flight that have been reported are: alterations in lymphocyte blastogenesis and natural killer cell activity, alterations in production of cytokines, changes in leukocyte sub-population distribution, and decreases in the ability in the ability of bone marrow cells to respond to colony stimulating factors. Changes have been reported in immunological parameters of both humans and rodents. The significance of these alterations in relation to resistance to infection remains to be established. The current study involved a determination of the effects of flight on Cosmos mission 2044 on leukocyte subset distribution and the sensitivity of bone marrow cells to colony stimulating factor-GM. A parallel study with antiorthostatic suspension was also carried out. The study involved repetition and expansion of studies carried out on Cosmos 1887.

  18. On immunological memory.

    PubMed Central

    Zinkernagel, R M

    Immunological memory may not represent a special characteristic of lymphocytes but simply reflect low-level responses driven by antigen that is re-encountered or persists within the host. T-cell memory is important to control persistent infections within the individual host and cannot be transmitted to offspring because of MHC polymorphism and MHC-restricted T-cell recognition. In contrast, antibody memory is transmissible from mother to offspring and may function essentially to protect offspring during the phase of physiological immuno-incompetence before, at and shortly after birth. This physiological immuno-incompetence is a result of MHC polymorphism and the dangers of the graft-versus-host and host-versus-graft reaction between mother and embryo, which necessitate immunosuppression of the mother and immuno-incompetence of the offspring. One may argue therefore that immunological memory of transmissible immunological experience is the basis on which MHC-restricted T-cell recognition could develop or coevolve. PMID:10794057

    2016-01-01

    Background Unexplained infertility remains as one of the important subtype of infertility that follows expectant management with Intrauterine Insemination (IUI) in most cases. Aim To evaluate the clinical role of progesterone supplement as luteal phase support for women with unexplained infertility following stimulation protocol with Clomiphene Citrate (CC)/Human Menopausal Gonadotropin (HMG). Materials and Methods An investigator initiated study to survey the success rate for first cycle of IUI following stimulation protocol with CC/HMG & luteal phase support with oral natural or synthetic progesterone was conducted. 120 patient records between observation period of Jan to May ’14 were retrieved especially for subjects undergoing IUI procedure for Unexplained infertility. Patients with baseline Serum (Sr). progesterone records who received Oral Natural Micronized Progesterone Sustained Release (Oral NMP SR) (N=45) or Dydrogesterone (n=33) following CC/HMG induction protocol and human Chorionic Gonadotropin(HCG) Inj., were further analysed following Luteal Phase Support(LPS) with oral natural or synthetic progesterone. Results Baseline demographics showed 78 patients with mean age, weight and cycle duration of 29.5 yrs, 57.3 kg & 28.6 days respectively. Progesterone was supplemented as Oral NMP SR 200/300 mg OD or Dydrogesterone 10 mg bid in 22, 23 and 33 patients respectively. In all cases ovulation was triggered with HCG inj., followed by IUI within the next 48 hours while baseline sr. progesterone levels were being assessed. Medicines and Healthcare Products Regulatory Agency (MHRA) UK recommended therapeutic compliance to suggest sr. progesterone levels of ≥14ng/ml were recorded as Mid-luteal levels in all of these patients. This therapeutic compliance was noted in 82.2% & 78.8% of the patients treated with oral NMP SR or Dydrogesterone respectively. Pregnancy was observed amongst 5 and 10 patients treated with oral NMP SR and Dydrogesterone respectively at

    A coordinated series of experiments were conducted to evaluate immunologic and hemotologic system responses of Skylab crewmen to prolonged space flights. A reduced PHA responsiveness was observed on recovery, together with a reduced number of T-cells, with both values returning to normal 3 to 5 days postflight. Subnormal red cell count, hemoglobin concentration, and hematocrit values also returned gradually to preflight limits. Most pronounced changes were found in the shape of red blood cells during extended space missions with a rapid reversal of these changes upon reentry into a normal gravitational environment.

We collect a representative sample of studies in T-cell biology that illustrate the benefits of modelling–experimental collaborations and that have proven valuable or even groundbreaking. We conclude that it is possible to find excellent examples of synergy between mathematical modelling and experiment in immunology, which have brought significant insight that would not be available without these collaborations, but that much remains to be discovered.

    Africa is a continent with a large burden of both infectious and non-communicable diseases. If we are to move forward as a continent, we need to equip our growing cadre of exceptional young scientists with the skills needed to tackle the diseases endemic to this continent. For this, immunology is among the key disciplines. Africans should be empowered to study and understand the diseases that affect them, and to perform their cutting-edge research in their country of origin. This requires a multifaceted approach, with buy-in from funders, overseas partners and perhaps, most important of all, African governments themselves.

    In Italy, according to the International Study on Asthma and Allergies in Childhood study, the prevalence of current asthma, allergic rhinoconjunctivitis, and atopic eczema in 2006 was 7.9%, 6.5%, and 10.1% among children aged 6-7 and 8.4%, 15.5%, and 7.75% among children aged 13-14 yr. University education in this field is provided by the Postgraduate Schools of Pediatrics and those of Allergology and Clinical Immunology, as well as several annual Master courses. The Italian Society of Pediatric Allergology and Immunology (SIAIP) was founded in 1996 and counts about 1000 members. SIAIP promotes evidence-based management of allergic children and disseminates information to patients and their families through a quite innovative website and the National Journal 'Rivista Italiana di Allergologia Pediatrica'. In the last decade, four major regional, inter-regional, and national web-based networks have been created to link pediatric allergy centers and to share their clinical protocols and epidemiologic data. In addition, National Registers of Primary Immune-deficiencies and on Pediatric HIV link all clinical excellence centers. Research projects in the field of pediatric allergy and immunology are founded by the Italian Ministry of Education, University and Research (MIUR) and by the National Research Council (CNR), but the overall investments in this research area are quite low. Only a handful Italian excellence centers participate in European Projects on Pediatric Allergy and Immunology within the 7th Framework Program. The European Academy of Allergy and Clinical Immunology currently hosts two Italians in its Executive Committee (EC) and one in the EC of the Pediatric Section; moreover, major European Academy of Allergy and Clinical Immunology meetings and courses in the area of pediatrics (e.g., PAAM, Venice, 2009) have been held in Italy in the last 3 yr.

    1971-01-01

    Knowledge of the immunological basis of the leishmaniases and of the host's response is fragmentary and largely pragmatic. This paper reviews certain conceptual and clinical aspects of the immunology of these diseases. Consideration is given to man's natural resistance and his ability to acquire resistance from natural infections and from vaccination. The age-distribution of infection in different populations is discussed in relation to the effects that interaction between the parasite and its intermediate host may have on its infection characteristics and virulence. Studies in the USSR of differences in virulence among 30 human strains and 39 rodent strains are reported. The rodent strains showed a broader range of virulence than did the human isolates. Serological tests for determining species relationships among the leishmaniae are generally nonspecific, but work concerned with the development of the antiserum—culture test is reviewed. Species identification and the recognition of new forms, perhaps with different infection characteristics, is, nevertheless, of the utmost importance in the prevention and treatment of the disease. The review concludes with a discussion of functional immunity and hypotheses of the immune process in leishmaniasis. PMID:5316252

    Colley, D G; Secor, W E

    2014-01-01

    There is a wealth of immunologic studies that have been carried out in experimental and human schistosomiasis that can be classified into three main areas: immunopathogenesis, resistance to reinfection and diagnostics. It is clear that the bulk of, if not all, morbidity due to human schistosomiasis results from immune-response-based inflammation against eggs lodged in the body, either as regulated chronic inflammation or resulting in fibrotic lesions. However, the exact nature of these responses, the antigens to which they are mounted and the mechanisms of the critical regulatory responses are still being sorted out. It is also becoming apparent that protective immunity against schistosomula as they develop into adult worms develops slowly and is hastened by the dying of adult worms, either naturally or when they are killed by praziquantel. However, as with anti-egg responses, the responsible immune mechanisms and inducing antigens are not clearly established, nor are any potential regulatory responses known. Finally, a wide variety of immune markers, both cellular and humoral, can be used to demonstrate exposure to schistosomes, and immunologic measurement of schistosome antigens can be used to detect, and thus diagnose, active infections. All three areas contribute to the public health response to human schistosome infections. PMID:25142505

    PubMed Central

    Barnaba, Vincenzo; Paroli, Marino; Piconese, Silvia

    2012-01-01

    In the present article, we discuss the various ambiguous aspects of the immune system that render this complex biological network so highly flexible and able to defend the host from different external invaders. This ambiguity stems mainly from the property of the immune system to be both protective and harmful. Immunity cannot be fully protective without producing a certain degree of damage (immunopathology) to the host. The balance between protection and tissue damage is, therefore, critical for the establishment of immune homeostasis and protection. In this review, we will consider as ambiguous, various immunological tactics including: (a) the opposing functions driving immune responses, immune-regulation, and contra-regulation, as well as (b) the phenomenon of chronic immune activation as a result of a continuous cross-presentation of apoptotic T cells by dendritic cells. All these plans participate principally to maintain a state of chronic low-level inflammation during persisting infections, and ultimately to favor the species survival. PMID:22566903

    PubMed

    Beverley, P C L

    2002-01-01

    An ideal vaccine is relatively easy to define, but few real vaccines approach the ideal and no vaccines exist for many organisms, for which a vaccine is the only realistic protective strategy in the foreseeable future. Many difficulties account for the failure to produce these vaccines. All micro-organisms deploy evasion mechanisms that interfere with effective immune responses and, for many organisms, it is not clear which immune responses provide effective protection. However, recent advances in methods for studying immune response to pathogens have provided a better understanding of immune mechanisms, including immunological memory, and led to the realisation that the initiation of immune responses is a key event requiring triggering through 'danger' signals. Based on these findings, the development of novel adjuvants, vectors and vaccine formulations allowing stimulation of optimal and prolonged protective immunity should lead to the introduction of vaccines for previously resistant organisms.

    The immune capabilities of the Peyer's patches have been investigated by the use of an in vitro system. Despite our failure to stimulate Peyer's patch lymphocytes in vivo it appears that Peyer's patches behave immunologically as peripheral lymphoid tissues. Cultures prepared from the dissociated Peyer's patches of normal rabbits respond to sheep erythrocytes. The response is comparable to that obtained with spleen cultures from the same animals and is not dependent on the presence of the epithelial cells which line the lumen. Similar thymic cultures do not respond. Our experiments with cultures prepared from rabbits which have received one or two injections of SRC show that the Peyer's patches contain both IgM and IgG "memory" cells which have migrated from the spleen. The concentration of these cells in the spleen remains several hundredfold higher. PMID:5463217

    Study objective To determine if day 3 FSH and E2 levels at the upper limits of normal affect live birth rates and treatment trajectory in a conventional vs. ‘fast track’ treatment program for IVF. Design Secondary analysis of two randomized controlled trials, FASTT and FORT-T. Setting Multicenter study in a state with mandated insurance coverage. Patients Infertile women ages 21 to 42 years randomized to conventional or accelerated treatment with controlled ovarian hyperstimulation (COH)-IUI and/or IVF (n=603 patients contributing 2,717 total cycles). Interventions Patients were stratified according to basal FSH and E2: FSH <10mIU/mL and E2 <40pg/mL (Group 1A), FSH <10mIU/mL and E2 ≥40 pg/mL (Group 1B), FSH 10–15 mIU/mL and E2 <40pg/mL (Group 2A) and FSH 10–15 mIU/mL and E2 ≥40 pg/mL (Group 2B). Main outcome measures Number of cancelled cycles, disenrollment for poor response and cumulative live birth rates per couple. Results Women in Groups 2A and 2B were more likely to have cancelled cycles and be disenrolled for poor response. While no live births occurred in Group 2B during COH-IUI (0/19 couples, 0/58 cycles), IVF still afforded these patients a reasonable chance of success (6/18 couples, 6/40 cycles, 33.3% live birth rate per couple). The specificity and positive predictive value of basal FSH 10–15 mIU/mL and E2 ≥40 pg/mL for no live birth during COH-IUI treatment were both 100%. Conclusions Women who initiated infertility treatment with FSH 10–15 mIU/mL and E2 ≥ 40 pg/mL on day 3 testing were unlikely to achieve live birth after COH-IUI treatment. PMID:25226857

Respondents represented both academic and private practice settings, and differences existed in the evaluation and management of hydrosalpinges. More than one-half (57%) perform their own hysterosalpingograms (HSGs), and 54.5% involve radiologists in their interpretation of tubal disease. Most respondents thought that a clinically significant hydrosalpinx on HSG is one that is distally occluded (80.4%) or visible on ultrasound (60%). Approximately one in four respondents remove a unilateral hydrosalpinx before controlled ovarian hyperstimulation (COH)/intrauterine insemination (IUI) and clomiphene citrate (CC)/IUI (29.3% and 22.8%, respectively), and physicians in private practice were more likely to intervene (COH: risk ratio [RR] 1.81, 95% confidence interval [CI] 1.31–2.51; CC: RR 1.98, 95% CI 1.33–2.95). Although laparoscopic salpingectomy was the preferred method of surgical management, nearly one-half responded that hysteroscopic tubal occlusion should have a role as a primary method of intervention. Conclusion(s) SREI/SRS members define a “clinically significant hydrosalpinx” consistently, and actual practice among members reflects American Society for Reproductive Medicine/SRS recommendations, with variation attributed to individual patient needs.

    Immunological investigations of 37 patients with bagassosis, 92 unaffected bagasse workers, and 150 non-exposed controls showed that precipitins against extracts of bagasse could be demonstrated just as frequently in the unaffected and the non-exposed as in the affected. However, there was a general tendency for the precipitin levels of patients with bagassosis to fall slightly with increasing time after recovery from the clinical episode. The presence of the precipitins so far demonstrated in the sera of bagasse workers therefore appears to be of no clinical significance. Inhalation tests with an extract of bagasse, in a group of 16 patients who had had bagassosis, produced late, systemic reactions in 15 similar to those described in farmer's lung and bird fancier's lung, so supporting the hypothesis that a similar type of hypersensitivity is the cause of bagassosis. Inhalation of extracts of Thermoactinomyces vulgaris also produced typical, late reactions in 12 out of 15 subjects, whereas extracts of Micropolyspora faeni failed to produce reactions in any of 16 subjects. The specific reactions to inhalation tests with Thermoactinomyces vulgaris were typical of a precipitin-mediated type of hypersensitivity reaction and support the view that this actinomycete may be important in the aetiology of bagassosis.

    The cross-talk between the mucosa-associated immune system and microbiota is critical in mucosal tissue homeostasis as well as in protection against infectious and inflammatory diseases occurring at mucosal sites. This recent evidence has paved the way to therapeutic approaches aimed at modulating the mucosa-associated immune system using probiotics. Different strains of probiotics possess the ability to finely regulate dendritic cell (DC) activation, polarizing the subsequent T cell activity toward Th1 (e.g. Lactobacillus (Lb) acidophilus), Th2 (Lb.reuteri and Bifidobacterium bifidum) or, as more recently demonstrated, Th17 responses induced by specific strains such as Lb.rhamnosus GG and Lac23a, the latter isolated in our laboratory. Here, we review some recent advances in our understanding of probiotics effects on mucosal immunology, particularly on cells of the innate immunity such as DCs. We also highlight our own experiences in modulating DC functions by commensal bacteria and discuss the relevance of probiotics administration in the treatment of human immunopathologies.

  17. Immunology of schistosomiasis*

    PubMed Central

    1974-01-01

    This Memorandum, after summarizing the life cycle of the different species of human schistosome, reviews the present knowledge of the immunology of schistosomiasis. Each stage of the parasite contains antigen that may stimulate an immune response. However, at the moment there are no accepted serological in vitro tests that correlate with protection; this develops only after the host has experienced a living infection, which suggests that the stimulation of immunity is due to some metabolic process involving the release of protective antigen. The adult worm, however, seems to be able to escape the immune mechanism of the host. Specific antigens are also released by the eggs, and the immune response against these antigens seems to cause granuloma formation around the egg itself. The granuloma is the main lesion found in schistosomiasis. Evidence for protective immunity in experimental animals and man is reviewed, together with the possible mechanism by which the adult worm escapes the immune response of the host. A review of methods used for the diagnosis of schistosomiasis and a list of recommendations for further research are also included. PMID:4219757

    An organism's fitness is critically reliant on its immune system to provide protection against parasites and pathogens. The structure of even simple immune systems is surprisingly complex and clearly will have been moulded by the organism's ecology. The aim of this review and the theme issue is to examine the role of different ecological factors on the evolution of immunity. Here, we will provide a general framework of the field by contextualizing the main ecological factors, including interactions with parasites, other types of biotic as well as abiotic interactions, intraspecific selective constraints (life-history trade-offs, sexual selection) and population genetic processes. We then elaborate the resulting immunological consequences such as the diversity of defence mechanisms (e.g. avoidance behaviour, resistance, tolerance), redundancy and protection against immunopathology, life-history integration of the immune response and shared immunity within a community (e.g. social immunity and microbiota-mediated protection). Our review summarizes the concepts of current importance and directs the reader to promising future research avenues that will deepen our understanding of the defence against parasites and pathogens.

  19. Immunology of lymphatic filariasis.

    Babu, S; Nutman, T B

    2014-08-01

    The immune responses to filarial parasites encompass a complex network of innate and adaptive cells whose interaction with the parasite underlies a spectrum of clinical manifestations. The predominant immunological feature of lymphatic filariasis is an antigen-specific Th2 response and an expansion of IL-10 producing CD4(+) T cells that is accompanied by a muted Th1 response. This antigen-specific T-cell hyporesponsiveness appears to be crucial for the maintenance of the sustained, long-standing infection often with high parasite densities. While the correlates of protective immunity to lymphatic filariasis are still incompletely understood, primarily due to the lack of suitable animal models to study susceptibility, it is clear that T cells and to a certain extent B cells are required for protective immunity. Host immune responses, especially CD4(+) T-cell responses clearly play a role in mediating pathological manifestations of LF, including lymphedema, hydrocele and elephantiasis. The main underlying defect in the development of clinical pathology appears to be a failure to induce T-cell hyporesponsiveness in the face of antigenic stimulation. Finally, another intriguing feature of filarial infections is their propensity to induce bystander effects on a variety of immune responses, including responses to vaccinations, allergens and to other infectious agents. The complexity of the immune response to filarial infection therefore provides an important gateway to understanding the regulation of immune responses to chronic infections, in general.

    2004-08-01

    Immunological memory is defined by the ability of a host to remember a past encounter with a specific pathogen and to respond to it in an effective manner upon re-exposure. How long immunological memory can be maintained in the absence of re-infection continues to be a subject of great controversy. Recent studies on immunity following smallpox vaccination demonstrate that T-cell memory declines steadily with a half-life of 8-15 years, whereas antiviral antibody responses are maintained for up to 75 years without appreciable decline. By combining recent advances in quantitative immunology with historical accounts of protection against smallpox dating back to the time of Edward Jenner, we are gaining a better understanding of the duration and magnitude of immunological memory and how it relates to protective immunity.

    Cohly, Hari Har Parshad; Panja, Asit

    2005-01-01

    The immunopathogenesis of autism is presented schematically in Fig. 1. Two main immune dysfunctions in autism are immune regulation involving pro-inflammatory cytokines and autoimmunity. Mercury and an infectious agent like the measles virus are currently two main candidate environmental triggers for immune dysfunction in autism. Genetically immune dysfunction in autism involves the MHC region, as this is an immunologic gene cluster whose gene products are Class I, II, and III molecules. Class I and II molecules are associated with antigen presentation. The antigen in virus infection initiated by the virus particle itself while the cytokine production and inflammatory mediators are due to the response to the putative antigen in question. The cell-mediated immunity is impaired as evidenced by low numbers of CD4 cells and a concomitant T-cell polarity with an imbalance of Th1/Th2 subsets toward Th2. Impaired humoral immunity on the other hand is evidenced by decreased IgA causing poor gut protection. Studies showing elevated brain specific antibodies in autism support an autoimmune mechanism. Viruses may initiate the process but the subsequent activation of cytokines is the damaging factor associated with autism. Virus specific antibodies associated with measles virus have been demonstrated in autistic subjects. Environmental exposure to mercury is believed to harm human health possibly through modulation of immune homeostasis. A mercury link with the immune system has been postulated due to the involvement of postnatal exposure to thimerosal, a preservative added in the MMR vaccines. The occupational hazard exposure to mercury causes edema in astrocytes and, at the molecular level, the CD95/Fas apoptotic signaling pathway is disrupted by Hg2+. Inflammatory mediators in autism usually involve activation of astrocytes and microglial cells. Proinflammatory chemokines (MCP-1 and TARC), and an anti-inflammatory and modulatory cytokine, TGF-beta1, are consistently

    The data of the ISAAC project in Spain show a prevalence of childhood asthma ranging from 7.1% to 15.3%, with regional differences; a higher prevalence, 22.6% to 35.8%, is described for rhinitis, and atopic dermatitis is found in 4.1% to 7.6% of children. The prevalence of food allergy is 3%. All children in Spain have the right to be visited in the National Health System. The medical care at the primary level is provided by pediatricians, who have obtained their titles through a 4-yr medical residency training program. The education on pediatric allergy during that period is not compulsory and thus very variable. There are currently 112 certified European pediatric allergists in Spain, who have obtained the accreditation of the European Union of Medical Specialist for proven skills and experience in pediatric allergy. Future specialists in pediatric allergy should obtain their titles through a specific education program to be developed in one of the four accredited training units on pediatric allergy, after obtaining the title on pediatrics. The Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) gathers over 350 pediatric allergists and pediatricians working in this field. SEICAP has a growing activity including yearly congresses, continued education courses, elaboration of technical clinical documents and protocols, education of patients, and collaboration with other scientific societies and associations of patients. The official journal of SEICAP is Allergologia et Immunophatologia, published every 2 months since 1972. The web site of SEICAP, http://www.seicap.es, open since 2004, offers information for professionals and extensive information on pediatric allergic and immunologic disorders for the lay public; the web site is receiving 750 daily visits during 2011.

    Cancer immunology is the study of interaction between cancer cells and immune system by the application of immunology principle and theory. With the recent approval of several new drugs targeting immune checkpoints in cancer, cancer immunology has become a very attractive field of research and is thought to be the new hope to conquer cancer. This chapter introduces the aberrant expression and function of noncoding RNAs, mainly microRNAs and long noncoding RNAs, in tumor-infiltrating immune cells, and their significance in tumor immunity. It also illustrates how noncoding RNAs are shuttled between tumor cells and immune cells in tumor microenvironments via exosomes or other microvesicles to modulate tumor immunity. PMID:27376738

    Immunology has played a prominent role in the history of medicine. Pediatric immunologists have focused on immune aberrations in pediatric disorders, particularly those involving host defense mechanisms. These efforts have paid rich dividends in terms of fundamental knowledge of the immune system and major therapeutic advances, including 1) i.v. immunoglobulin therapy, 2) hematopoietic stem cell transplantation, and 3) gene therapy. Pediatric immunology as an organized discipline emerged in the early 1950s, when pediatricians and their basic scientist colleagues began to focus on clinical and basic research related to immunodeficiency. Since then, key organizations and infrastructure have been developed to support this research and the clinical care of immunodeficient patients. We review here the evolution of contemporary pediatric immunology, particularly in North America, from its roots in 19th-century Europe to its current expression as one of the fundamental scientific and clinical disciplines of pediatrics.

    Sarcoidosis is a multisystem granulomatous disorder invariably affecting the lungs. It is a disease with noteworthy variations in clinical manifestation and disease outcome and has been described as an “immune paradox” with peripheral anergy despite exaggerated inflammation at disease sites. Despite extensive research, sarcoidosis remains a disease with undetermined aetiology. Current evidence supports the notion that the immune response in sarcoidosis is driven by a putative antigen in a genetically susceptible individual. Unfortunately, there currently exists no reliable biomarker to delineate the disease severity and prognosis. As such, the diagnosis of sarcoidosis remains a vexing clinical challenge. In this review, we outline the immunological features of sarcoidosis, discuss the evidence for and against various candidate etiological agents (infective and noninfective), describe the exhaled breath condensate, a novel method of identifying immunological biomarkers, and suggest other possible immunological biomarkers to better characterise the immunopathogenesis of sarcoidosis.

    The Japanese Society of Pediatric Allergy and Clinical Immunology (JSPACI) was started in 1966 and currently has 3613 members as of August 1, 2012. The number of pediatricians specializing in allergies who have been certified by the Japanese Society of Allergology is 817. Among these, there are 125 training directors and training facilities for allergy and clinical immunology. The JSPACI first published an asthma guideline specific for children in 2000, and this has been revised every 3 yrs, contributing to better control of pediatric asthma. Food allergy management guidelines were first developed in 2005, which have helped to improve the care of food allergy patients. Among 514 pediatric training programs by the Japanese Society of Pediatrics, there are 312 facilities routinely performing oral food challenges. Among these, there were already 53 facilities performing oral immunotherapy at the end of 2011, treating 1400 cases of food allergy. The prevalence of pediatric allergic diseases has increased in Japan over the past 50 yrs. A number of International Study of Asthma and Allergies in Childhood surveys have been conducted in the past at specific times. The prevalence of wheezing among children aged 13-14 yrs in 2002 was 13.0%. Multi-year surveys found a 1.5- to 2-fold increase every 10 yrs until 2002. However, according to the latest data in 2012, asthma prevalence seems to have slightly decreased in Japan. Food allergy mainly associated with infantile atopic eczema among infants younger than 1 yr of age is the most common form as with other developed countries. The estimated food allergy prevalence based on data from several surveys is 5-10% among infants (0-6 yrs) and 1-2% among schoolchildren (6-15 yrs). A variety of patients suffering from primary deficiency syndrome have been actively analyzed. Previously, antibody defects and well-defined syndromes with immunodeficiency were analyzed, but recent research is focusing on not only acquired immune

    Background The aim of this study was to evaluate the efficacy and safety of a recombinant human follicle stimulating hormone (r-FSH) low-dose step-up regimen for controlled ovarian hyperstimulation in patients undergoing ovulation induction (OI) with intrauterine insemination (IUI). Materials and Methods The study was conducted in the Department of Obstetrics and Gynecology, Far Eastern Memorial Hospital, New Taipei, Taiwan. In this prospective, observational study, consecutive infertile women (20-35 years) with regular menstrual cycles and a normal baseline FSH level were prospectively enrolled between January 2010 and September 2010. A starting dose of 112.5 IU/day r-FSH was administered on day 3 and increased by 37.5 IU/day every 2 days until a follicle ≥11 mm in diameter was present. Recombinant human chorionic gonadotropin (r-hCG) was administered when a follicle ≥18 mm was noted. Monifollicular development was defined as only one follicle with a diameter ≥16 mm. Clinical pregnancy was defined as a pregnancy diagnosed by ultrasonographic visualization of one or more gestational sacs. Results A total of 29 women and 30 cycles were included. The mean daily dose of r-FSH to achieve a follicle of ≥11 mm in diameter was 131.3 ± 23.6 IU and the mean total dose was 1030.0 ± 383.2 IU. Approximately 41% of the cycles were monofollicular. Clinical pregnancy was observed in 9 (30.0%) cycles, and a fetal heart beat was observed in 7 (23.3%). There were no multiple pregnancies. Mild ovarian hyperstimulation syndrome, which was resolved with conservative management, was observed in 3 (10.0%) cycles. Conclusion This r-FSH low-dose step-up regimen seems to be a feasible and practical method for OI in younger infertile women undergoing IUI. PMID:26985331

    Immunological changes in elite adolescent female athletes during Taekwondo competitions were investigated on-field. 6 female athletes (16.7 ± 0.8 year-old) volunteered and performed 5 bouts of demonstration Taekwondo competitions simulating real tournaments in intensity, duration, and break-time intervals on the same day. Blood samples were taken before, after the competitions and during the recovery, respectively. Immunological changes and oxidative stress in peripheral blood mononuclear cells were evaluated by flow-cytometry. During the competitions, exercise intensity was 92.2 ± 3.8% (86.1~95.7) of the maximal heart rate. Blood lactate increased immediately after the competitions (p=0.0165) and decreased to baseline during recovery. Intracellular reactive oxygen species (ROS) in the peripheral blood increased continuously during recovery (p<0.05, respectively). Natural killer cells increased immediately after the competitions (p=0.0006), and decreased during recovery. B and T cells increased immediately after the competitions and remained elevated throughout recovery (p<0.05, respectively). CD4/CD8 ratio after the competitions was decreased (p=0.0091) and returned to baseline during recovery. These results suggest that the immunological function of the elite female adolescent athletes could be attenuated after Taekwondo competitions. Further large-scaled Taekwondo studies on immunologic and apoptotic changes related to oxidative stress should be performed for improving and protecting the health of adolescent athletes.

    On October 27, 2012, the 17th annual Alcohol and Immunology Research Interest Group (AIRIG) meeting was held at the Grand Wailea Hotel in Maui, Hawaii as a satellite meeting to the 2012 Society of Leukocyte Biology conference. This year's meeting focused on the influence of alcohol on signal transduction pathways in various disease and injury models. Three plenary sessions were held where invited speakers shared their research on alcohol-mediated alterations of cell signaling components, immune cell subsets, and inflammation. These studies suggested alcohol has a negative effect on cell signaling machinery and immune cell homeostasis, resulting in disease, disease progression, and increased mortality. Researchers also identified tissue-specific alcohol-linked elevations in markers of inflammation, including cold-shock proteins and microRNAs. Additionally, one study revealed the effects of alcohol on immune cell subsets in a model of allergic asthma.

      Human immunological memory is the key distinguishing hallmark of the adaptive immune system and plays an important role in the prevention of morbidity and the severity of infection. The differentiation system of T cell memory has been clarified using mouse models. However, the human T cell memory system has great diversity induced by natural antigens derived from many pathogens and tumor cells throughout life, and profoundly differs from the mouse memory system constructed using artificial antigens and transgenic T cells. We believe that only human studies can elucidate the human immune system. The importance of immunological memory in cancer immunotherapy has been pointed out, and the trafficking properties and long-lasting anti-tumor capacity of memory T cells play a crucial role in the control of malignant tumors. Adoptive cell transfer of less differentiated T cells has consistently demonstrated superior anti-tumor capacity relative to more differentiated T cells. Therefore, a human T cell population with the characteristics of stem cell memory is thought to be attractive for peptide vaccination and adoptive cell transfer. A novel human memory T cell population that we have identified is closer to the naive state than previous memory T cells in the T cell differentiation lineage, and has the characteristics of stem-like chemoresistance. Here we introduce this novel population and describe the fundamentals of immunological memory in cancer immunotherapy.

    Summary Understanding the mechanisms underlying the induction of immunity in the gastrointestinal mucosa following oral immunization and the cross-talk between mucosal and systemic immunity should expedite the development of vaccines to diminish the global burden caused by enteric pathogens. Identifying an immunological correlate of protection in the course of field trials of efficacy, animal models (when available), or human challenge studies is also invaluable. In industrialized country populations, live attenuated vaccines (e.g. polio, typhoid, and rotavirus) mimic natural infection and generate robust protective immune responses. In contrast, a major challenge is to understand and overcome the barriers responsible for the diminished immunogenicity and efficacy of the same enteric vaccines in underprivileged populations in developing countries. Success in developing vaccines against some enteric pathogens has heretofore been elusive (e.g. Shigella). Different types of oral vaccines can selectively or inclusively elicit mucosal secretory immunoglobulin A and serum immunoglobulin G antibodies and a variety of cell-mediated immune responses. Areas of research that require acceleration include interaction between the gut innate immune system and the stimulation of adaptive immunity, development of safe yet effective mucosal adjuvants, better understanding of homing to the mucosa of immunologically relevant cells, and elicitation of mucosal immunologic memory. This review dissects the immune responses elicited in humans by enteric vaccines. PMID:21198669

  20. Immunology taught by human genetics.

    2013-01-01

    Human genetic studies are rarely conducted for immunological purposes. Instead, they are typically driven by medical and evolutionary goals, such as understanding the predisposition or resistance to infectious or inflammatory diseases, the pathogenesis of such diseases, and human evolution in the context of the long-standing relationships between humans and their commensal and environmental microbes. However, the dissection of these experiments of Nature has also led to major immunological advances. In this review, we draw on some of the immunological lessons learned in the three branches of human molecular genetics most relevant to immunology: clinical genetics, epidemiological genetics, and evolutionary genetics. We argue that human genetics has become a new frontier not only for timely studies of specific features of human immunity, but also for defining general principles of immunity. These studies teach us about immunity as it occurs under "natural" conditions, through the transition from the almost complete wilderness that existed worldwide until about a century ago to the current unevenly distributed medically shaped environment. Hygiene, vaccines, antibiotics, and surgery have considerably decreased the burden of infection, but these interventions have been available only recently, so have yet to have a major impact on patterns of genomic diversity, making it possible to carry out unbiased evolutionary studies at the population level. Clinical genetic studies of childhood phenotypes have not been blurred by modern medicine either. Instead, medical advances have actually facilitated such studies, by making it possible for children with life-threatening infections to survive. In addition, the prevention and treatment of infectious diseases have increased life expectancy at birth from ∼20 yr to ∼80 yr, providing unique opportunities to study the genetic basis of immunological phenomena against which there is no natural counterselection, such as

  1. Immunological aspects of chronic venous disease pathogenesis

    2014-01-01

    Chronic venous disease (CVD) is a very common health problem concerning up to 1/3 of the society. Although venous hypertension and valvular incompetence have been long known to be crucial for development of the illness, its exact aetiology remains unclear. Recent findings indicate that inflammatory processes may be crucial for development of incompetent valves and vein wall remodelling. One of the most interesting theories describes “leucocyte trapping” as the mechanism responsible for elevated vein wall permeability and oxidative stress in the veins. At the same time, the cytokine profile of the blood in incompetent veins has not been thoroughly examined. Popular anti-inflammatory drugs relieve some symptoms but do not have much proved effects in prevention and treatment. We intend to summarize the existing knowledge of the immunological aspects of CVD in order to emphasize its importance for understanding the aetiology of this illness. We also wish to indicate some aspects that remain to be studied in more detail. PMID:26155174

  2. Development of the discipline of exercise immunology.

    PubMed

    2010-01-01

    Interest in the influence of exercise upon the human white cell population dates back more than a 100 years. Thus, when introducing the third meeting of the International Society of Exercise Immunology in Brussels, Dr. Bente Klarlund-Pedersen noted that Schulte had already described an exercise-induced leukocytosis as early as 1893. However, for much of the following century interest remained strictly clinical, with physicians assessing the possible changes in vulnerability to bacterial and viral diseases that were induced by various forms of physical activity. In the absence of specific remedies, bed rest was a common medical recommendation for infectious disease, and if the patient recovered from the immediate infection there was often a substantial residual loss of physical condition. Army hospitals in particular were thus anxious to know whether recovery would be compromised if physical activity were to be encouraged during convalescence. Prominent concerns of this era were the influence of exercise upon anterior poliomyelitis and viral hepatitis. The paralysis resulting from the anterior poliomyelitis virus was generally localized to body parts that had been active, and it seemed most likely to develop in those who continued to engage in vigorous exercise in the face of early symptoms (46, 57, 119, 120). Data on viral hepatitis also suggested a need for rest in the acute phase of the disease (1, 65, 115, 128), although most authors concluded that in this condition exercise could be resumed during convalescence, provided that the patient was no longer severely jaundiced (5, 32, 136).

    Rheumatoid arthritis (RA) is the most common connective tissue disease of autoimmune origin. The disease is characterized by chronic inflammation leading to bone erosions and organ involvement. RA is a progressive disease. It affects the quality of life, leading to disability and death mainly due to premature cardiovascular disease. Early diagnosis and appropriate treatment are essential for prognosis and quality of life improvement. In 2010 the American College of Rheumatology (ACR) and The European League Against Rheumatism (EULAR) established new RA classification criteria. Besides clinical symptoms it includes two immunologic criteria: rheumatoid factor (RF) and anti-citrullinated protein antibodies (anti-CCP antibodies). RF is the first well-known RA immunologic marker. It is observed in 80-85% of patients with RA. Elevated serum level of RF has been associated with increased disease activity, radiographic progression, and the presence of extraarticular manifestations. The sensitivity of RF is 50-90%, and specificity is 50-95%. Anti-CCP antibodies appear to be a more specific marker than RF. They are often present at the very beginning of the disease, or even years before the first symptoms. The prognostic value of anti-CCP antibodies is well established. High serum level of anti-CCP correlates with poor prognosis and early erosions of the joints. The sensitivity of anti-CCP2 is 48-80%, and specificity is 96-98%. New immunologic markers include anti-carbamylated protein antibodies (anti-CarP) and antibodies against heterogeneous nuclear ribonucleoproteins (anti-hnRNP A2/B1, RA33). Scientists aim to identify a highly sensitive and specific biomarker of the disease that not only has diagnostic and prognostic value but also may predict the response to treatment.

    The patient was a 32-year-old obese woman with a history of type 2 diabetes and hypertension for 6 years. Although she was treated with antihypertensive agents and intensive insulin therapy, her hyperglycemia was difficult to control. She wanted to have a baby but pregnancy was not recommended because her diabetes was under poor control and the use of antihypertensive medication. To achieve good control of obesity, diabetes and hypertension, she was admitted to our clinical department for weight reduction using very low calorie diet (VLCD). During VLCD she had a 19.8 kg reduction in body weight and her blood glucose and blood pressure were in good control without the use of drugs. Five months later, she became pregnant after the fourth trial of intrauterine insemination (IUI) and gave birth to a female baby under insulin therapy. This is the first report that showed the usefulness of VLCD for prepregnant control of glucose metabolism and blood pressure in an obese hypertensive patient with type 2 diabetes mellitus.

In this summary we present spaceflight studies with human subjects, animal subjects, and cell cultures and we review ground-based systems used to model the observed effects of spaceflight on the immune system. Human paradigms include bed rest, academic or psychological stress, physical stress, hypobaric or high altitude stress, and confinement. Animal models include antiorthostatic and orthostatic suspension, hypobarism, and confinement. The ten manuscripts in this collection were selected to provide a summary that should give the reader an overview of the various activities of spaceflight immunology researchers throughout the history of space travel. This manuscript identifies the major contributors to the study of spaceflight immunology, explains what types of studies have been conducted, and how they have changed over the years. Also presented is a discussion of the unusual limitations associated with spaceflight research and the efforts to develop appropriate ground-based surrogate model systems. Specific details, data, and mechanistic speculations will be held to a minimum, because they will be discussed in depth in the other articles in the collection.

    In spite of the eradication of smallpox over 30 years ago; orthopox viruses such as smallpox and monkeypox remain serious public health threats both through the possibility of bioterrorism and the intentional release of smallpox and through natural outbreaks of emerging infectious diseases such as monkeypox. The eradication effort was largely made possible by the availability of an effective vaccine based on the immunologically cross-protective vaccinia virus. Although the concept of vaccination dates back to the late 1800s with Edward Jenner, it is only in the past decade that modern immunologic tools have been applied toward deciphering poxvirus immunity. Smallpox vaccines containing vaccinia virus elicit strong humoral and cellular immune responses that confer cross-protective immunity against variola virus for decades after immunization. Recent studies have focused on: establishing the longevity of poxvirus-specific immunity, defining key immune epitopes targeted by T and B cells, developing subunit-based vaccines, and developing genotypic and phenotypic immune response profiles that predict either vaccine response or adverse events following immunization.

    Autoimmune disease occurs when the immune system attacks self-molecules as a result of a breakdown of immunologic tolerance to autoreactive immune cells. Many autoimmune disorders have been strongly associated with genetic, infectious, and/or environmental predisposing factors. Comprising multiple disorders and symptoms ranging from organ-specific to systemic, autoimmune diseases include insulin-dependent diabetes mellitus, rheumatoid arthritis, systemic lupus erythematosus, scleroderma, thyroiditis, and multiple sclerosis. There are also implications of autoimmune pathology in such common health problems as arteriosclerosis, inflammatory bowel disease, schizophrenia, and certain types of infertility. Largely of unknown etiology, autoimmune disorders affect approximately 3% of the North American and European populations, > 75% of those affected being women. This discussion provides a brief introduction to the immune system and tolerance maintenance, an overview of selected autoimmune diseases and possible mechanisms of immune autoreactivity, and a review of experimental autoimmune models.

    We have studied several aspects of cellular and humoral immunity in 19 patients with chronic osteomyelitis (CO) compared with 11 healthy controls of similar characteristics. Patients with CO showed significantly higher values of GSR, reactive protein C (RPC), IgG and lymphocytes CD3+ and lower values of the CD4+/CD3+ ratio, as well as an hypoergic response to 7 antigens in the different cutaneous hypersensibility tests, compared with healthy controls. The rate of "in vitro" blastic stimulation by different lectins was significantly lower in the group of patients, compared with controls. These changes in the cellular immunity are not correlated with the extent, chronicity and prognosis of the disease, although we did not performed sequential studies of the immunitary condition. None of these immunological markers seem to be a better predictor of the bone infectious activity than the traditional GSR or RPC. PMID:1467399

    Split immunological tolerance refers to states in which an individual is capable of mounting certain types of immune responses to a particular antigenic challenge, but is tolerant of the same antigen in other compartments of the immune system. This concept is applicable to the immunological relationship between mother and fetus, and particularly relevant in equine pregnancy. In pregnant mares, antibody responses to paternal foreign Major Histocompatibility Complex class I antigens are robust, while anti-paternal cytotoxic T cell responses are diminished compared to those mounted by non-pregnant mares. Here we compared the distribution of the major lymphocyte subsets, the percentage of lymphocytes expressing Interferon Gamma (IFNG) and Interleukin 4 (IL4) and the level of expression of the immunoregulatory transcription factor FOXP3 between pregnant and non-pregnant mares, and between peripheral blood and the endometrium during pregnancy. In a cohort of mares in which peripheral blood lymphocytes were tested during early pregnancy and in the non-pregnant state, there were only slight changes observed during pregnancy. In contrast, comparison of peripheral blood lymphocytes with lymphocytes isolated from the endometrial cups of pregnant mares revealed striking differences in lymphocyte sub-populations. The endometrial cups contained higher numbers of IFNG+ lymphocytes, and lower numbers of lymphocytes expressing IL4. The endometrial cup lymphocytes also had higher numbers of FOXP3+ cells compared to peripheral blood lymphocytes. Taken together, these results strengthen the evidence for a state of split tolerance to trophoblast, and furthermore define sharp differences in immune reactivity during equine pregnancy between peripheral blood lymphocytes and lymphocytes at the maternal-fetal interface.

    The increasing disease susceptibility in different whale and dolphin populations has led to speculation about a possible negative influence of environmental contaminants on the immune system and therefore on the health status of marine mammals. Despite current efforts in the immunology of marine mammals several aspects of immune functions in aquatic mammals remain unknown. However, assays for evaluating cellular immune responses, such as lymphocyte proliferation, respiratory burst as well as phagocytic and cytotoxic activity of leukocytes and humoral immune responses have been established for different cetacean species. Additionally, immunological and molecular techniques enable the detection and quantification of pro- and anti-inflammatory cytokines in lymphoid cells during inflammation or immune responses, respectively. Different T and B cell subsets as well as antigen-presenting cells can be detected by flow cytometry and immunohistochemistry. Despite great homologies between marine and terrestrial mammal lymphoid organs, some unique anatomical structures, particularly the complex lymphoepithelial laryngeal glands in cetaceans represent an adaptation to the marine environment. Additionally, physiological changes, such as age-related thymic atrophy and cystic degeneration of the "anal tonsil" of whales have to be taken into account when investigating these lymphoid structures. Systemic morbillivirus infections lead to fatalities in cetaceans associated with generalized lymphoid depletion. Similarly, chronic diseases and starvation are associated with a loss of functional lymphoid cells and decreased resistance against opportunistic infections. There is growing evidence for an immunotoxic effect of different environmental contaminants in whales and dolphins, as demonstrated in field studies. Furthermore, immunomodulatory properties of different persistent xenobiotics have been confirmed in cetacean lymphoid cells in vitro as well as in animal models in vivo

    Background There are still many questions about the ideal protocol for letrozole (LTZ) as the commonest aromatase inhibitor (AI) used in ovulation induction. The aim of this study is to compare the ultrasonographic and hormonal characteristics of two different initiation times of LTZ in clomiphene citrate (CC) failure patients and to study androgen dynamics during the cycle. Materials and Methods This randomized clinical trial was done from March to November 2010 at the Mashhad IVF Center, a university based IVF center. Seventy infertile polycystic ovarian syndrome (PCOS) patients who were refractory to at least 3 CC treatment cycles were randomly divided into two groups. Group A (n=35) receiving 5 mg LTZ on cycle days 3-7 (CD3), and group B (n=35) receiving the same amount on cycle days 5-9 (CD5). Hormonal profile and ultrasonographic scanning were done on cycle day 3 and three days after completion of LTZ treatment (cycle day 10 or 12). Afterward, 5,000-10,000 IU human chorionic gonadotropin (hCG) was injected if at least one follicle ≥18 mm was seen in ultrasonographic scanning. Intrauterine insemination (IUI) has been done 36-40 hours later. The cycle characteristics, the ovulation and pregnancy rate were compared between two groups. The statistical analysis was done using Fisher’s exact test, t test, logistic regression, and Mann-Whitney U test. Results There were no significant differences between two groups considering patient characteristics. The ovulation rate (48.6 vs. 32.4% in group A and B, respectively), the endometrial thickness, the number of mature follicles, and length of follicular phase were not significantly different between the two groups. Conclusion LTZ is an effective treatment in CC failure PCOS patients. There are no significant differences regarding ovulation and pregnancy rates between two different protocols of LTZ starting on days 3 and 5 of menstrual cycle (Registration Number: IRCT201307096467N3).

    The science of immunology emerged in the last of the 19th and the first of the 20th century. Substantial progress in physics, chemistry and microbiology was essential for its development. Indeed, microorganisms became one of the principal investigative tools of the major founders of that science - Louis Pasteur, Robert Koch, Ilya Ilich Metchnikoff, Paul Ehrlich and Jules Bordet. It is pertinent that these pioneering scientists were born when questioning and exploration were encouraged because of the legacies of the previous century of enlightenment. Mentors greatly aided their development. Their discoveries were shaped by their individual personalities. In turn they developed other contributors to the nascent field. Their discoveries included the types of leukocytes, the roles of neutrophils in inflammation and defence, cellular lysis due to complement, the principles of humoral and cellular immunology, passive and active immunization, tissue antigens, anaphylaxis, anaphylactoid reactions and autoimmunity. Their work formed the basis of modern immunology that developed many decades later. Immunology has enormously impacted our understanding of the pathogenesis, diagnosis and treatment of infections, immune-mediated disorders and inflammation. Burgeoning advances forecast further important clinical applications of immunology. Yet, their applications will be problematic because few physicians sufficiently understand the science. We propose that understanding modern immunology requires a grasp of how that science developed - who made the discoveries, how they were made, their successes and failures, their interactions and debates all reveal the foundation of modern immunology.

    Experimental cryosurgery has been found to result in the formation of circulating antibodies, directed against antigenic material of the tissue frozen. These antibodies were detected by passive haemagglutination and immunodiffusion. The tissue that was subjected to destructive freezing by means of this surgical procedure was the coagulating gland and seminal vesicle of rabbit. A probe carrying liquid nitrogen and a thermocouple assembly for measuring temperature changes was utilized. Control rabbits were manipulated in the same way but with no freezing. A large number of rabbits subjected to tissue freezing exhibited the development of a rapid antibody response, achieving a maximum titre in 7–10 days, followed by a decline. This antibody response has been compared to that seen following isoimmunization by injection. As an additional comparison, several rabbits were autoimmunized by injection of homogenate from their own accessory tissue; these rabbits also produced antibodies. It was found that the time sequence in the antibody production was quite similar for auto- and isoimmunization, but was quite distinctive for cryo-stimulation. By several means of evaluation, it was shown that the antibody response to the freezing of tissue was an autoantibody. It was not, however, an antibody against serum γ-globulin. The consequences of the freezing of tissue are thus seen to simulate the effects of incorporating adjuvant. This method of producing autoantibodies and investigating the nature of the response has been termed cryo-immunology. ImagesFIG. 4 PMID:4960713

    The availability of cells, tissues and organs from a non-human species such as the pig could, at least in theory, meet the demand of organs necessary for clinical transplantation. At this stage, the important goal of getting over the first year of survival has been reported for both cellular and solid organ xenotransplantation in relevant preclinical primate models. In addition, xenotransplantation is already in the clinic as shown by the broad use of animal-derived medical devices, such as bioprosthetic heart valves and biological materials used for surgical tissue repair. At this stage, however, prior to starting a wide-scale clinical application of xenotransplantation of viable cells and organs, the important obstacle represented by the humoral immune response will need to be overcome. Likewise, the barriers posed by the activation of the innate immune system and coagulative pathway will have to be controlled. As far as xenogeneic nonviable xenografts, increasing evidence suggests that considerable immune reactions, mediated by both innate and adaptive immunity, take place and influence the long-term outcome of xenogeneic materials in patients, possibly precluding the use of bioprosthetic heart valves in young individuals. In this context, the present article provides an overview of current knowledge on the immune processes following xenotransplantation and on the possible therapeutic interventions to overcome the immunological drawbacks involved in xenotransplantation.

  5. The Immunological Functions of Saposins

    2014-01-01

    Saposins or sphingolipid activator proteins (SAPs) are small, nonenzymatic glycoproteins that are ubiquitously present in lysosomes. SAPs comprise the five molecules saposins A–D and the GM2 activator protein. Saposins are essential for sphingolipid degradation and membrane digestion. On the one hand, they bind the respective hydrolases required to catabolize sphingolipid molecules; on the other hand, saposins can interact with intralysosomal membrane structures to render lipids accessible to their degrading enzymes. Thus, saposins bridge the physicochemical gap between lipid substrate and hydrophilic hydrolases. Accordingly, defects in saposin function can lead to lysosomal lipid accumulation. In addition to their specific functions in sphingolipid metabolism, saposins have membrane-perturbing properties. At the low pH of lysosomes, saposins get protonated and exhibit a high binding affinity for anionic phospholipids. Based on their universal principle to interact with membrane bilayers, we present the immunological functions of saposins with regard to lipid antigen presentation to CD1-restricted T cells, processing of apoptotic bodies for antigen delivery and cross-priming, as well as their potential antimicrobial impact.

    The purpose of the work carried under this interchanges was to support the development of space flight biotechnology experiments in the areas of immunology and hematopoiesis to facilitate the commercial development of space. The studies involved the interaction and development of experiments with biotechnology companies for necessary ground-based studies to allow the development of flight studies. The thrust of the work was to develop experiments with the Chiron Corporation and Bioserve involving the use of interleukin-2 to modulate the effects of spaceflight on immune responses. Spaceflight has been shown to have multiple effects on immune responses (1). lnterleukin-2 is an immuno-regulator that could have potential to counter some of the alterations induced in immune responses by spaceflight (1). To test this possibility before flight, rats were suspended antiorthostatically (2) and treated with interleukin-2. Antiorthostatic suspension is a model for some of the effects of spaceflight on immune responses (2). The interleukin-2 was given to see if it could alter some of the effects of suspension. This was achieved. As a result of these studies, two flight experiments were developed and flown with the Chiron Corp. And Bioserve to determine if use of interleukin-2 could prevent or attenuate the effects of space flight on immune responses.

  7. Instructive selection and immunological theory.

    PubMed

    Lederberg, Joshua

    2002-07-01

    The turning point of modern immunological theory was the advent of the clonal selection theory (Burnet, Talmage - 1957). A useful heuristic in the classification of theoretical models was the contrast of 'instructive' with 'selective' models of the acquisition of information by biological systems. The neo-Darwinian synthesis of the 1940s had consolidated biologists' model of evolution based on prior random variation and natural selection, viz. differential fecundity. While evolution in the large was by then pretty well settled, controversy remained about examples of cellular adaptation to chemical challenges, like induced drug-resistance, enzyme formation and the antibody response. While instructive theories have been on the decline, some clear cut examples can be found of molecular imprinting in the abiotic world, leading, e.g. to the production of specific sorbents. Template-driven assembly, as in DNA synthesis, has remained a paradigm of instructive specification. Nevertheless, the classification may break down with more microscopic scrutiny of the processes of molecular fit of substrates with enzymes, of monomers to an elongating polymer chain, as the reactants often traverse a state space from with activated components are appropriately selected. The same process may be 'instructive' from a holistic, 'selective' from an atomic perspective.

    Many factors, such as environmental, microbial and endogenous stress, antigen localization, can trigger the immunological events that affect the ending of the diverse spectrum of ocular disorders. Significant advances in understanding of immunological and molecular mechanisms have been researched to improve the diagnosis and therapy for patients with ocular inflammatory diseases. Some kinds of ocular diseases are inadequately responsive to current medications; therefore, immunotherapy may be a potential choice as an alternative or adjunctive treatment, even in the prophylactic setting. This article first provides an overview of the immunological and molecular mechanisms concerning several typical and common ocular diseases; second, the functions of immunological roles in some of systemic autoimmunity will be discussed; third, we will provide a summary of the mechanisms that dictate immune cell trafficking to ocular local microenvironment in response to inflammation.

    One of the greatest challenges in biomedicine is to get a unified view of observations made from the molecular up to the organism scale. Towards this goal, multiscale models have been highly instrumental in contexts such as the cardiovascular field, angiogenesis, neurosciences and tumour biology. More recently, such models are becoming an increasingly important resource to address immunological questions as well. Systematic mining of the literature in multiscale modelling led us to identify three main fields of immunological applications: host-virus interactions, inflammatory diseases and their treatment and development of multiscale simulation platforms for immunological research and for educational purposes. Here, we review the current developments in these directions, which illustrate that multiscale models can consistently integrate immunological data generated at several scales, and can be used to describe and optimize therapeutic treatments of complex immune diseases.

  10. Pathogen evolution and the immunological niche

    PubMed Central

    Cobey, Sarah

    2014-01-01

    Host immunity is a major driver of pathogen evolution and thus a major determinant of pathogen diversity. Explanations for pathogen diversity traditionally assume simple interactions between pathogens and the immune system, a view encapsulated by the susceptible–infected–recovered (SIR) model. However, there is growing evidence that the complexity of many host–pathogen interactions is dynamically important. This revised perspective requires broadening the definition of a pathogen's immunological phenotype, or what can be thought of as its immunological niche. After reviewing evidence that interactions between pathogens and host immunity drive much of pathogen evolution, I introduce the concept of a pathogen's immunological phenotype. Models that depart from the SIR paradigm demonstrate the utility of this perspective and show that it is particularly useful in understanding vaccine-induced evolution. This paper highlights questions in immunology, evolution, and ecology that must be answered to advance theories of pathogen diversity. PMID:25040161

    This review highlights the fundamental role of nutrition in the maintenance of health, the immune response, and disease prevention. Emerging global mechanistic insights in the field of nutritional immunology cannot be gained through reductionist methods alone or by analyzing a single nutrient at a time. We propose to investigate nutritional immunology as a massively interacting system of interconnected multistage and multiscale networks that encompass hidden mechanisms by which nutrition, microbiome, metabolism, genetic predisposition, and the immune system interact to delineate health and disease. The review sets an unconventional path to apply complex science methodologies to nutritional immunology research, discovery, and development through “use cases” centered around the impact of nutrition on the gut microbiome and immune responses. Our systems nutritional immunology analyses, which include modeling and informatics methodologies in combination with pre-clinical and clinical studies, have the potential to discover emerging systems-wide properties at the interface of the immune system, nutrition, microbiome, and metabolism.

The features observed at the immunological synapse show parallels to centrosome (basal body) polarization seen in cilia and flagella, and the cellular communication that is now known to occur at all of these sites.

    Brand, Anneke

    2016-01-01

    Most adverse blood transfusion (BT) events are immune-mediated and in the majority of severe reactions antibodies can be identified as causal factors. Alloimmunization not only causes symptomatic reactions, transfused cells can also be (silently) destroyed. Immunization by BT can contribute to hemolytic disease of the newborn as well as to allograft rejection after transplantation. Reversely, pregnancy and transplantation may evoke immunity hampering transfusion therapy. Besides causing mortality and morbidity, alloimmunization has a huge economic impact. Transfusion reactions prolong hospital stay, require diagnostic tests and complex donor selection procedures and create the need for typed donor registries. In the 1970s, Opeltz and colleagues described that pre-transplantation BT impaired rejection of renal transplants. Leukocytes were essential for this immunosuppressive BT effect that raised concern about negative effects on cancer growth and resistance against infections. Studies on the mechanism were however preliminary abandoned when calcineurin inhibitors for prevention of graft rejection became available and since all blood products underwent leukoreduction in most countries as precautionary measure against transmission of variant Creutzfeldt-Jacob disease. Whether current leukoreduced BT are immunosuppressive and for which patients or circumstances this may contribute to worse outcome, is unknown. The last decades of the previous century, leukoreduction of cellular blood products for leukemia patients significantly reduced the incidence of immunological platelet transfusion refractoriness. The first decade of this century the avoidance of plasma- and platelet-products from females, that may contain donor-derived leukocyte antibodies, decreased transfusion related acute lung injury (TRALI) by more than 30%. These were major achievements. Challenge for the near future is to further reduce alloimmunization in particular against red blood cells (RBC) as a

    Beside the monoaminergic deficiency concept as a pathophysiological correlate of depressive disorder, the role of increased glutamatergic neurotransmission is increasingly being discussed. Causes and interactions of these neurotransmitter disturbances are not fully understood to date. This review presents a concept integrating actual findings of the neurotransmitter dysregulations with immunological and morphological findings in depressive disorder. Several intertwined mechanisms seem to be important: The common cause of serotonin deficiency and increased glutamatergic neurotransmission seems to be the increase of proinflammatory cytokines. Immune activation with increased production of proinflammatory cytokines activate the tryptophan- and serotonin-degradating enzyme indolamine-2,3-dioxygenase (IDO). The increased consumption of serotonin and its precursor tryptophan due to IDO activation may explain the reduced availability of serotonin in depression. In inflammatory somatic disorders, depressive mood is associated with an increase of proinflammatory cytokines and increased consumption of tryptophan. This activation of IDO by proinflammatory cytokines leads to the production of glutamatergic agonists. In the CNS, IDO is activated during inflammatory processes primarily in microglial cells. Therefore the astrocyte:microglial balance in depression is important. The observed decrease of astrocytes in the CNS of depressive patients may contribute to a regulatory fault in the activity of IDO in microglial cells but also can cause an alteration of the glutamatergic neurotransmission. By this mechanism, the dysbalance of the immune response and the astrocyte:microglia dysbalance may contribute to serotonergic deficiency and glutamatergic overproduction in depression. The further search for new antidepressant therapeutic mechanisms should take into regard anti-inflammatory substances, e.g. cyclo-oxygenase-2 (COX-2)-inhibitors. PMID:17928982

    After the geographic and sociodemographic settings as well as the health care in Israel are briefly described, the scope of pediatric allergy and immunology in Israel is presented. This includes specific disorders commonly encountered, the environment that induces symptoms, the specialists who treat them, and the common challenges of patients, parents, doctors, and allied health personnel who collaborate to manage the maladies and patient care. Allergies usually affect some overall 15-20% of the pediatric population. The main allergens are inhaled, ingested, or injected (insects stings). Generally, the incidence of the various allergens affecting children in Israel, is similar to other parts of the Western world. Owing to the high consanguinity rate in the Israeli population, the prevalence of the various immunodeficiency conditions (in the adaptive as well as the innate system) is higher than that reported worldwide. Pediatric allergists/immunologists also treat autoimmune disorders affecting the pediatric group. Pediatric allergy and clinical immunology are not separate specialties. The 25 specialists who treat children with allergic/immunologic diseases have undergone a basic training in Pediatrics. They also received an additional 2-yr training in allergy and clinical immunology and then have to pass the board examinations. They work mainly in pediatric allergy units, in several hospitals that are affiliated to the five medical schools in the country. Aside from clinical work, most of the centers are also heavily involved in clinical and basic research in allergy and immunology.

    An immunological surrogate endpoints is a vaccine-induced immune response (either humoral or cellular immune) that predicts protection against clinical endpoints (infection or disease), and can be used to evaluate vaccine efficacy in clinical vaccine trials. Compared with field efficacy trials observing clinical endpoints, immunological vaccine trials could reduce the sample size or shorten the duration of a trial, which promote the license and development of new candidate vaccines. For these reasons, establishing immunological surrogate endpoints is one of 14 Grand Challenges of Global Health of the National Institutes of Health (NIH) and the Bill and Melinda Gates Foundation. From two parts of definition and statistical methods for evaluation of surrogate endpoints, this review provides a more comprehensive description. PMID:26887309

    2014-01-01

    Xenotransplantation, or the transplantation of cells, tissues, or organs between different species, was proposed a long time ago as a possible solution to the worldwide shortage of human organs and tissues for transplantation. In this setting, the pig is currently seen as the most likely candidate species. In the last decade, progress in this field has been remarkable and includes a better insight into the immunological mechanisms underlying the rejection process. Several immunological hurdles nonetheless remain, such as the strong antibody-mediated and innate or adaptive cellular immune responses linked to coagulation derangements, precluding indefinite xenograft survival. This article reviews our current understanding of the immunological mechanisms involved in xenograft rejection and the potential strategies that may enable xenotransplantation to become a clinical reality in the not-too-distant future.

    The mother's and the offspring's immunological system are closely related thus one can influence the other. This hypothesis drove our aim to study the impact of the mother's immunological status over the immunological response of their offspring. For this, female mice tolerant or allergic to peanuts were exposed or not to a challenge diet containing peanuts during the gestation-lactation period (TEP/AEP; TNEP/ANEP, respectively). After weaning the offspring was submitted to the peanut allergy or peanut tolerization protocol and then challenged with a peanut diet. Our results showed that when the offspring is submitted to the allergy induction protocol, they behave differently depending on their mother's immunological status. Offspring born to TEP mothers produced the lowest antibody titters while those born to AEP mothers produced the highest antibody titters compared to mice born to TNEP and ANEP. On the other hand when the offspring was submitted to the tolerization protocol all groups presented low antibody titers with no significant difference between groups, independent of the mothers immunological status and/or contact with peanuts during the gestation-lactation period. The analysis of the histological profile of the offspring correlates well to the serological response. In other words, offspring born to TEP mothers and submitted to the allergy induction protocol presented a normal histological profile, while the offspring born to AEP mothers produced the worst gut inflammation. These results indicate that mothers, exposed to the antigen (by the oral route) during gestation, actively influence the immune response of their offspring. This work sheds some light on the importance of the immunomodulation induced by dietary antigens during gestation and their influence on the immunological response of their offspring. However, more work is needed to elucidate the molecular and cellular components of this regulatory phenomenon.

    Studies on immunologic memory in animal models and especially in the human system are instrumental to identify mechanisms and correlates of protection necessary for vaccine development. In this article, we provide an overview of the cellular basis of immunologic memory. We also describe experimental approaches based on high throughput cell cultures, which we have developed to interrogate human memory T cells, B cells, and plasma cells. We discuss how these approaches can provide new tools and information for vaccine design, in a process that we define as 'analytic vaccinology'.

  11. Translational research in immunology: Japanese perspectives.

    PubMed

    Triendl, Robert

    2004-01-01

    Japan has a formidable tradition in immunological research, starting with Shibasaburo Kitasato (1852-1931), who, after returning to Japan from his studies with Robert Koch, went on to build almost single-handedly a research tradition in investigative medical research, while engaging himself in the fight against infectious diseases. Over the past few decades, Japanese immunologists have been involved in many important discoveries at the forefront of immunological research, yet, when it comes to the translation of new discoveries into clinical innovations and new therapies, Japan's track record seems more modest.

    Brain metastases represent the most common type of brain tumor. These tumors offer a dismal prognosis and significantly impact quality of life for patients. Their capacity for central nervous system (CNS) invasion is dependent upon induced disruptions to the blood-brain barrier (BBB), alterations to the brain microenvironment, and mechanisms for escaping CNS immunosurveillance. In the emerging era of immunotherapy, understanding how metastases are influenced by the immunologic peculiarities of the CNS will be crucial to forging therapeutic advances. In this review, the immunology of brain metastasis is explored. PMID:27622023

    Proteus syndrome (PS) is an extremely rare and complex disease characterized by malformations and overgrowth of different tissues. Prognosis of affected patients may be complicated by premature death, mostly due to pulmonary embolism and respiratory failure. To date, immunological data in Proteus syndrome are scarse.We report on the novel immunologic findings of a 15 years old girl affected with PS. Detailed T and B cell evaluation revealed maturational alterations for both subsets and functional hyperactivation for the latter. Such findings have not been reported previously in PS and may be the spy of more complex immune abnormalities in this syndrome. PMID:26758562

    Schneider, David S

    2016-04-01

    Speculative fiction examines the leading edge of science and can be used to introduce ideas into the classroom. For example, most students are already familiar with the fictional infectious diseases responsible for vampire and zombie outbreaks. The disease dynamics of these imaginary ailments follow the same rules we see for real diseases and can be used to remind students that they already understand the basic rules of disease ecology and immunology. By engaging writers of this sort of fiction in an effort to solve problems in immunology we may be able to perform a directed evolution experiment where we follow the evolution of plots rather than genetic traits.

    Clinical immunology is in the Netherlands a separate clinical specialty within internal medicine and pediatrics. Clinical immunologists work closely together with nephrologists, rheumatologists and many other medical specialists. Apart from research and teaching, clinical immunologists are taking care of patients with immune-deficiencies, vasculitides and systemic auto-immune diseases. Clinical immunology in the Netherlands has always been an important contributor to basic and clinical science in the Netherlands. Major scientific contributions were made in the field of Systemic Lupus Erythematosus and ANCA associated vasculitis. These Dutch contributions will be reviewed in this article.

    Geering, Barbara; Fussenegger, Martin

    2015-02-01

    Humans have manipulated the immune system to dampen or boost the immune response for thousands of years. As our understanding of fundamental immunology and biotechnological methodology accumulates, we can capitalize on this combined knowledge to engineer biological devices with the aim of rationally manipulating the immune response. We address therapeutic approaches based on the principles of synthetic immunology that either ameliorate disorders of the immune system by interfering with the immune response, or improve diverse pathogenic conditions by exploiting immune cell effector functions. We specifically highlight synthetic proteins investigated in preclinical and clinical trials, summarize studies that have used engineered immune cells, and finish with a discussion of possible future therapeutic concepts.

    The Indian Vacuum Society (IVS) was established in 1970. It has over 800 members including many from Industry and R & D Institutions spread throughout India. The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC. As part of the development of vacuum education, the society arranges the participation of

    Summary In this review article, some recent developments in the immunology of parasitic infections are presented. After an introduction in which the major human parasitic infectious diseases, including malaria, african and american trypanosomiasis, leishmaniasis, filariasis an schistosomiasis are mentioned, a description of the host / parasite relationship in malaria presented. The possibility for the development of vaccins against malaria are described. The close relation between the immunological responses and the inflammatory reactions present both in Schistosoma mansoni and Trichinella spiralis infections is stressed. Particularly the recently recognized direct anti-parasitic activity of eosinophils was emphasized. Next, ways of escape of parasites from the host defence were described, with special emphasis on the immunomodulating properties of parasitic infections. Finally, the development and improvement of new immunodiagnostic methods, including the detection of circulating antigens were discussed.

    Unwanted immunity develops in response to many protein drugs, in autoimmunity, in allergy, and in transplantation. Approaches to induce immunological tolerance aim to either prevent these responses or reverse them after they have already taken place. We present here recent developments in approaches, based on engineered peptides, proteins and biomaterials, that harness mechanisms of peripheral tolerance both prophylactically and therapeutically to induce antigenspecific immunological tolerance. These mechanisms are based on responses of B and T lymphocytes to other cells in their immune environment that result in cellular deletion or ignorance to particular antigens, or in development of active immune regulatory responses. Several of these approaches are moving toward clinical development, and some are already in early stages of clinical testing.

  17. Immunological effects of ayahuasca in humans.

    PubMed

    dos Santos, Rafael Guimarães

    2014-01-01

    Ayahuasca is a botanical hallucinogen traditionally used by indigenous groups of the northwest Amazon. In the last decade, the use of ayahuasca has spread from Brazil, Colombia, Ecuador, and Peru to the U.S., Europe, Asia, and Africa. Despite acute and long-term evidence of good tolerability and safety for ayahuasca administered in the laboratory or ritually consumed in religious contexts, little is known about the immunological impact of ayahuasca on humans. Since ayahuasca is used by an increasing number of consumers, and considering its therapeutic potential, more information is needed regarding ayahuasca potential risks. This article presents a brief overview of the available data regarding the immunological impact of ayahuasca in humans. PMID:25364989

    Messaoudi, Ilhem; Basler, Christopher F.

    2015-01-01

    Several enveloped RNA viruses of the arenavirus, bunyavirus, filovirus and flavivirus families are associated with a syndrome known as viral hemorrhagic fever (VHF). VHF is characterized by fever, vascular leakage, coagulation defects and multi organ system failure. VHF is currently viewed as a disease precipitated by viral suppression of innate immunity, which promotes systemic virus replication and excessive proinflammatory cytokine responses that trigger the manifestations of severe disease. However, the mechanisms by which immune dysregulation contributes to disease remain poorly understood. Infection of nonhuman primates closely recapitulates human VHF, notably Ebola and yellow fever, thereby providing excellent models to better define the immunological basis for this syndrome. Here we review the current state of our knowledge and suggest future directions that will better define the immunological mechanisms underlying VHF. PMID:26163194

    Schülke, Stefan; Scheurer, Stephan

    2016-06-01

    Recent advances in immunology have greatly improved our understanding of the pathomechanisms of food allergies. Food allergies are caused and maintained by complex interactions of the innate and adaptive immune system involving antigen-presenting cells (APC), T cells, group 2 innate lymphoid cells (ILC2), epithelial cells (EC) and effectors cells. Additionally, epigenetic factors, the intestinal microbiome and nutritional factors modulating the gastrointestinal lymphatic tissue probably have a significant impact on allergy development. However, why certain individuals develop tolerance while others mount allergic responses, the factors defining the allergenicity of food proteins, as well as the immunological mechanisms triggering allergy development have yet to be analyzed in detail.

    Symposium 5 focused on research approaches that are aimed at understanding common patterns of immunological and neurological dysfunction contributing to neurodevelopmental disorders such as autism and ADHD. The session focused on genetic, epigenetic, and environmental factors that might act in concert to influence autism risk, severity and co-morbidities, and immunological and neurobiological targets as etiologic contributors. The immune system of children at risk of autism may be therefore especially susceptible to psychological stressors, exposure to chemical triggers, and infectious agents. Identifying early biomarkers of risk provides tangible approaches toward designing studies in animals and humans that yield a better understanding of environmental risk factors, and can help identify rational intervention strategies to mitigate these risks.

    There is some evidence to show that the immune response is suppressed in malnutrition but the mechanism is not entirely clear. A more complete understanding of nutritional—immunological relationships is important, especially for child health in developing countries. This memorandum discusses a general approach to the problem and proposes specific methods for investigating the effects of malnutrition on the immune response. Several field studies incorporating these proposals are now in progress. PMID:4538197

    Pulmonary intravascular macrophages (PIMs) are lung macrophages found apposed to the endothelium of pulmonary capillaries. In many species, they are responsible for the clearance of blood-borne particulates and pathogens; however, little else is known about their roles as immunologic effector cells. We compared PIMs with pulmonary alveolar macrophages (PAMs) to determine the relative immunological activities of these two cell populations. Our results suggested that both populations possess similar phagocytic and bactericidal activities. In assays measuring cytotoxicity, PIMs were more cytotoxic than PAMs against virally infected target cells; however, differences between these macrophage populations were not as marked when noninfected targets were used. LPS-stimulated PIMs produced more T-cell proliferative cytokines than PAMs, and both populations of nonstimulated macrophages produced similar amounts of the cytokines. In contrast, PAMs produced more TNF alpha and NO2- than PIMs when both populations were stimulated with LPS; however, nonstimulated PAMs and PIMs produced similar amounts of TNF alpha and NO2. These data suggest that bovine PIMs are immunologically active. Differences between the degrees of activity of PIMs and PAMs indicate that these macrophage populations may have different roles in lung surveillance.

    Plant biomass is the major renewable feedstock resource for sustainable generation of alternative transportation fuels to replace fossil carbon-derived fuels. Lignocellulosic cell walls are the principal component of plant biomass. Hence, a detailed understanding of plant cell wall structure and biosynthesis is an important aspect of bioenergy research. Cell walls are dynamic in their composition and structure, varying considerably among different organs, cells, and developmental stages of plants. Hence, tools are needed that are highly efficient and broadly applicable at various levels of plant biomass-based bioenergy research. The use of plant cell wall glycan-directed probes has seen increasing use over the past decade as an excellent approach for the detailed characterization of cell walls. Large collections of such probes directed against most major cell wall glycans are currently available worldwide.

    Plant biomass is the major renewable feedstock resource for sustainable generation of alternative transportation fuels to replace fossil carbon-derived fuels. Lignocellulosic cell walls are the principal component of plant biomass. Hence, a detailed understanding of plant cell wall structure and biosynthesis is an important aspect of bioenergy research. Cell walls are dynamic in their composition and structure, varying considerably among different organs, cells, and developmental stages of plants. Hence, tools are needed that are highly efficient and broadly applicable at various levels of plant biomass-based bioenergy research. The use of plant cell wall glycan-directed probes has seen increasing use over the past decade as an excellent approach for the detailed characterization of cell walls. Large collections of such probes directed against most major cell wall glycans are currently available worldwide. The largest and most diverse set of such probes consists of cell wall glycan-directed monoclonal antibodies (McAbs). These McAbs can be used as immunological probes to comprehensively monitor the overall presence, extractability, and distribution patterns among cell types of most major cell wall glycan epitopes using two mutually complementary immunological approaches, glycome profiling (an in vitro platform) and immunolocalization (an in situ platform). Significant progress has been made recently in the overall understanding of plant biomass structure, composition, and modifications with the application of these immunological approaches.

  6. Immunological aspects of pre-eclampsia.

    PubMed

    The first pregnancy preponderance and apparent partner specificity of pre-eclampsia suggest that it might have an immune aetiology. The pathogenesis of pre-eclampsia is undefined although it is clear that it is a placental disorder. The maternal syndrome appears to be mediated by placental ischaemia secondary to spiral artery insufficiency. This leads to a hypothesis that pre-eclampsia is a two-stage disease. The first comprises processes that limit the size of the spiral arteries (poor placentation) or obstruct them (acute atherosis). Either or both may have immunological causes although there is no direct evidence. Factors limiting placentation could involve maternal immune intolerance of the fetal allograft, which in their most extreme expression could lead to immunologically mediated abortion. Thus pre-eclampsia may be part of a wider spectrum of pregnancy loss secondary to poor maternal immune accommodation of her genetically disparate fetus. The second stage involves the consequences of the ensuing placental ischaemia. The syndrome is currently tentatively ascribed to diffuse maternal endothelial dysfunction. There is less reason to invoke immunological mechanisms in the second stage although neutrophil activation could explain generalized endothelial damage. It should be clear that these conclusions are provisional and that the greatest need is for more investigation to eliminate the uncertainty which clouds our concepts.

    Inflammatory bowel diseases (IBD) are inflammatory diseases with a multifactorial component that involve the intestinal tract. The two relevant IBD syndromes are Crohn's disease (CD) and ulcerative colitis (UC). One factor involved in IBD development is a genetic predisposition, associated to NOD2/CARD15 and Toll-like receptor 4 (TLR4) polymorphisms that might favor infectious enterocolitis that is possibly associated to the development of IBD. The identification of specific immunologic alterations in IBD and their relationship to the etiology of the disease is a relevant research topic. The role of intra and extracellular molecules, such as transcription factors and cytokines that are involved in the inflammatory response, needs to be understood. The relevance of immunologic molecules that might drive the immune response to a T helper (Th) 1, Th 2 or the recently described Th 17 phenotype, has been demonstrated in animal models and clinical studies with IBD patients. CD and UC predominantly behave with a Th 1 and Th 2 immune phenotype, respectively. Recently, an association between CD and Th 17 has been reported. The knowledge acquired from immunologic and molecular research will help to develop accurate diagnostic methods and efficient therapies.

    The subspecialty of pediatric allergy and immunology in Brazil is in its early years and progressing steadily. This review highlights the research developed in the past years aiming to show the characteristics of allergic and immunologic diseases in this vast country. Epidemiologic studies demonstrated the high prevalence of asthma in infants, children, and adolescents. Mortality rates and average annual variation of asthma hospitalization have reduced in all pediatric age groups. Indoor aeroallergen exposure is excessively high and contributes to the high rates of allergy sensitization. Prevalence of food allergy has increased to epidemic levels. Foods (35%), insect stings (30%), and drugs (23%) are the main etiological agents of anaphylaxis in children and adolescents. Molecular diagnosis of primary immunodeficiencies (PID) showed a high incidence of fungal infections including paracoccidioidomycosis in X-linked hyper-IgM syndrome, and the occurrence of BCG adverse reactions or other mycobacterial infections in patients with chronic granulomatous disease. Education in pediatric allergy and immunology is deficient for medical students, but residency programs are effective in training internists and pediatricians for the practice of allergy. The field of PID requires further training. Last, this review is a tribute to Prof. Dr. Charles Naspitz, one of the pioneers of our specialty in Brazil.

    Several immunological processes can be affected by space flight. However, there is little evidence to suggest that flight-induced immunological deficits lead to illness. Therefore, one of our goals has been to define models to examine host resistance during space flight. Our working hypothesis is that space flight crews will come from a heterogeneous population; the immune response gene make-up will be quite varied. It is unknown how much the immune response gene variation contributes to the potential threat from infectious organisms, allergic responses or other long term health problems (e.g. cancer). This article details recent efforts of the Kansas State University gravitational immunology group to assess how population heterogeneity impacts host health, either in laboratory experimental situations and/or using the skeletal unloading model of space-flight stress. This paper details our use of several mouse strains with several different genotypes. In particular, mice with varying MHCII allotypes and mice on the C57BL background with different genetic defects have been particularly useful tools with which to study infections by Staphylococcus aureus, Salmonella typhimurium, Pasteurella pneumotropica and Ehrlichia chaffeensis. We propose that some of these experimental challenge models will be useful to assess the effects of space flight on host resistance to infection.

    Immunology is the systematic evaluation of the means through which human beings protect themselves and respond to the attack of internal and external agents, and Edward Jenner (1749-1823) and Louis Pasteur (1822-1895) are considered pioneers of this field. Jenner observed the protective effect of cowpox against smallpox and inoculated the cowpox in human beings to protect them from the often lethal smallpox. Pasteur developed in his laboratory a vaccine against rabies and elaborated methods for attenuating the virulence of pathogenic microorganisms while maintaining their immunogenicity. Pharmacology is the area of medical science dealing with drugs and their uses, and it was during the nineteenth century that it assumed its status of scientific specialty, mainly in German-speaking Europe, through the establishment of pharmacological institutes and dedicated laboratories. The discovery and the synthesis of drugs and the systematic evaluation of their activity have constituted through time a scientific field in which immunology and pharmacology have met and given origin to notable progress in the history of science. The development of chemotherapy, as well as of organ and tissue transplantation, in the twentieth century has been decisively promoted by both immunology and pharmacology. In the last three decades the relationship between these two scientific branches has become increasingly closer in basic research, clinical science, medical education and also editorial scientific activity, as documented by the Journal hosting this paper.

    Despite recent tissue-engineering advances, there is no effective way of replacing all the functions of the larynx in those requiring laryngectomy. A recent clinical transplant was a success. Using quantitative immunofluorescence targeted at immunologically relevant molecules, we have studied the early (48 h and 1 week) immunological responses within larynxes transplantated between seven pairs of National Institutes of Health (NIH) minipigs fully homozygous at the major histocompatibility complex (MHC) locus. There were only small changes in expression of some molecules (relative to interindividual variation) and these were clearest in samples from the subglottic region, where the areas of co-expression of CD25+CD45RC-CD8- and of CD163+CD172+MHC-II- increased at 1 week after transplant. In one case, infiltration by recipient T cells was analysed by T cell receptor (TCR) Vβ spectratype analysis; this suggested that changes in the T cell repertoire occur in the donor subglottis mucosal tissues from day 0 to day 7, but that the donor and recipient mucosal Vβ repertoires remain distinct. The observed lack of strong immunological responses to the trauma of surgery and ischaemia provides encouraging evidence to support clinical trials of laryngeal transplantation, and a basis on which to interpret future studies involving mismatches.

    After decades of setbacks, cancer immunology is living its Golden Age. Recent advances in cancer immunology have provided new therapeutic approaches to treat cancer. The objective clinical response observed in patients treated with antibodies that block the immune checkpoints, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell-death protein 1 (PD-1)/programmed cell-death 1 ligand 1 (PD-L1) pathways, has led to their FDA approval for the treatment of melanoma in 2011 and in 2014, respectively. The anti-PD-1 antibody nivolumab has received the FDA-approval in March 2015 for squamous lung cancer treatment. In addition, antibodies targeting PD-1 or PD-L1 have demonstrated their efficacy and safety in additional tumors, including non-small cell lung carcinoma (NSCLC), renal cell carcinoma (RCC), bladder cancer, and Hodgkin's lymphoma. Almost at the same time, the field of adoptive cell transfer has exploded. The chimeric antigen receptor (CAR) T technology has provided strong evidence of efficacy in the treatment of B cell malignancies, and different T cell based treatments are currently under investigation for different types of tumors. In this review we will discuss the latest advances in cancer immunology and immunotherapy as well as new treatments now under development in the clinic and potential strategies that have shown promising results in preclinical models.

    Objective The objective is to perform a comprehensive review of the literature from January 2007 through June 2011 on the virology, bacteriology, and immunology related to otitis media. Data Sources PubMed database of the National Library of Medicine. Review Methods Three subpanels with co-chairs comprising experts in the virology, bacteriology, and immunology of otitis media were formed. Each of the panels reviewed the literature in their respective fields and wrote draft reviews. The reviews were shared with all panel members, and a second draft was created. The entire panel met at the 10th International Symposium on Recent Advances in Otitis Media in June 2011 and discussed the review and refined the content further. A final draft was created, circulated, and approved by the panel. Conclusion Excellent progress has been made in the past 4 years in advancing an understanding of the microbiology and immunology of otitis media. Advances include laboratory-based basic studies, cell-based assays, work in animal models, and clinical studies. Implications for Practice The advances of the past 4 years formed the basis of a series of short-term and long-term research goals in an effort to guide the field. Accomplishing these goals will provide opportunities for the development of novel interventions, including new ways to better treat and prevent otitis media. PMID:23536533

    Advances in technology and data analysis have made it possible to take a new look at human immunology. These advances run the gamut from systems biology approaches, which are likely in the vanguard of how we can start “to put the pieces together” of immune function, to a deeper understanding of specific diseases and vaccines and the immune repertoire. In our own experience, we have also found that asking simple questions about human immunity has often given us very surprising answers, causing a rethink of established dogma. Thus, we have developed a new perspective on the nature of the αβ TCR repertoire and also the likely role of T-cell repertoire (TCR) cross-reactivity in generating T memory independent of specific antigen interactions. These findings show that human immunology is not just a necessary step for “translating” basic immunology to treat diseases or develop better vaccines, but is also an important complement to the inbred mouse model.

    Sublingual immunotherapy is currently attracting growing interest because of its ease of administration and, according to previous studies, its infrequent and mild adverse effects. However, at least in children, the efficacy of this therapy has not been completely demonstrated. In addition, the mechanisms of action remain to be elucidated since few studies have been published and the results have been contradictory and sometimes inconclusive. For this reason, we performed a literature review through the MEDLINE database, selecting double-blind studies carried out in children. Only 10 studies meeting these requirements were retrieved. All the studies were performed by European researchers and nine were published in European journals. Efficacy was evaluated by clinical parameters and by reduction in medication use. The results on efficacy are not homogeneous, although most support the utility of this route of administration. Moreover, reports of allergens other than those used in these studies dust mites and grass pollens are lacking. In conclusion, further studies evaluating the efficacy of this therapy in children are required. Among the general population, if the efficacy of sublingual immunotherapy in the treatment of sensitization to hymenoptera venoms were demonstrated, as has been the case with subcutaneous immunotherapy, the utility of this route of administration would be definitively confirmed. Finally, sublingual immunotherapy could be used in children who have shown systemic reactions to subcutaneous immunotherapy or who refuse to undergo injections.

  3. Immunology and immunity against infection: General rules

    NASA Astrophysics Data System (ADS)

    Zinkernagel, Rolf M.

    2005-12-01

    Simplified and generalizable rules of immune responses against infections or vaccines have been summarized into 20 statements previously (Scand. J. Immunol. 60 (2004) 9-13) and are restated in a slightly different form here. The key terms of immunology (e.g. specificity, tolerance and memory) are explained in terms of their co-evolutionary importance in the equilibrium between infectious agents and diseases with higher vertebrate hosts. Specificity is best defined by protective antibodies or protective activated T cells; e.g. serotype specific neutralizing antibodies against polio viruses represent the discriminatory power of an immune response very well indeed. Tolerance is reviewed in terms of reactivity rather than self-nonself discrimination. Immune respones are deleted against antigens expressed at sufficient levels within the lymphoheamopoetic system, but may well exist at both, the T and the B cell level against antigens strictly outside of secondary lymphatic organs. In this respect the immune system behaves identically against virus infections and against self antigens. Persistent virus infections delete responsive T cells, once eliminated immune T cell responses wane, if a virus keeps outside of secondary lymphatic tissues no immune response is induced. Immunological memory is usually defined as earlier and greater responses but this does not correlate with protective immunity stringently. It is summarized here that pre-existing titers of protective neutralizing antibodies or pre-existence of activated T cells are the correlates of protection acute cytopathic lethal infections and toxins or against intracellular parasites. It is concluded that many discrepancies and uncertainties in immunological research derive from model situations and experimental results that are correctly measured but cannot be related to co-evolutionary contexts, i.e. survival.

  4. Immunological adjuvants: a role for liposomes.

    Recent technological advances have resulted in the production of safe subunit and synthetic small peptide vaccines. These vaccines are weakly or non-immunogenic and cannot, therefore, be used effectively in the absence of immunological adjuvants (agents that can induce strong immunity to antigens). Owing to the toxicity of adjuvants, only one (aluminium salts) has hitherto been licensed for use in humans, and it is far from ideal. In this article, Gregory Gregoriadis discusses the use of liposomes as an alternative safe, versatile, universal adjuvant that can induce humoral- and cell-mediated immunity to antigens when administered parenterally or enterally.

    The increasing number of elderly people with a demand for organ transplantation poses an important medical challenge. The effect of aging on the immune system concerns wide modifications with a considerable influence on transplant outcomes. Aging causes significant changes in immune cells repertoire. Thymic involution impairs the production of new naïve cells. Immune remodeling induces important alterations in the activity of immunological molecules. Therefore, clinical implications in elderly transplant recipients should consider appropriate organ allocation with adequate individualization of immunosuppression. PMID:26409504

    Immune memory has traditionally been the domain of the adaptive immune system, present only in antigen-specific T and B cells. The purpose of this review is to summarize the evidence for immunological memory in lower organisms (which are not thought to possess adaptive immunity) and within specific cell subsets of the innate immune system. A special focus will be given to recent findings in both mouse and humans for specificity and memory in natural killer (NK) cells, which have resided under the umbrella of innate immunity for decades. The surprising longevity and enhanced responses of previously primed NK cells will be discussed in the context of several immunization settings. PMID:24674969

    Just over a century ago, animal responses to injections of jellyfish extracts unveiled the phenomenon of anaphylaxis. Yet, until very recently, understanding of jellyfish sting toxicity has remained limited. Upon contact, jellyfish stinging cells discharge complex venoms, through thousands of barbed tubules, into the skin resulting in painful and, potentially, lethal envenomations. This review examines the immunological and toxinological responses to stings by prominent species of jellyfish including Physalia sp. (Portuguese Man-o-War, Blue-bottle), Cubozoan jellyfish including Chironex fleckeri, several Carybdeids including Carybdea arborifera and Alatina moseri, Linuche unguiculta (Thimble jellyfish), a jellyfish responsible for Irukandji syndrome (Carukia barnesi) and Pelagia noctiluca. Jellyfish venoms are composed of potent proteinaceous porins (cellular membrane pore-forming toxins), neurotoxic peptides, bioactive lipids and other small molecules whilst the tubules contain ancient collagens and chitins. We postulate that immunologically, both tubular structural and functional biopolymers as well as venom components can initiate innate, adaptive, as well as immediate and delayed hypersensitivity reactions that may be amenable to topical anti-inflammatory-immunomodifier therapy. The current challenge for immunotoxinologists is to deconstruct the actions of venom components to target therapeutic modalities for sting treatment. PMID:21824077

    2011-11-01

    Chronic physical exercise with adequate intensity and volume associated with sufficient recovery promotes adaptations in several physiological systems. While intense and exhaustive exercise is considered an important immunosuppressor agent and increases the incidence of upper respiratory tract infections (URTI), moderate regular exercise has been associated with significant disease protection and is a complementary treatment of many chronic diseases. The effects of chronic exercise occur because physical training can induce several physiological, biochemical and psychological adaptations. More recently, the effect of acute exercise and training on the immunological system has been discussed, and many studies suggest the importance of the immune system in prevention and partial recovery in pathophysiological situations. Currently, there are two important hypotheses that may explain the effects of exercise and training on the immune system. These hypotheses including (1) the effect of exercise upon hormones and cytokines (2) because exercise can modulate glutamine concentration. In this review, we discuss the hypothesis that exercise may modulate immune functions and the importance of exercise immunology in respect to chronic illnesses, chronic heart failure, malnutrition and inflammation.

    2015-01-01

    Summary Noroviruses (NoVs) are the most common cause of sporadic and epidemic gastroenteritis in the United States and Europe and are responsible for 20% of acute gastroenteritis worldwide. Over the past decade, the understanding of NoV immunology has grown immensely. Studies of the natural immune response to NoV in humans and animal models have laid the foundation for innovations in cell culture systems for NoV and development of new therapeutics. Evidence from animal models, NoV surrogates, observational human research, and human challenge studies suggest that the innate immune response is critical for limiting NoV infection but is insufficient for viral clearance. NoV may antagonize the innate immune response to establish or prolong infection. However, once a robust adaptive immune response is initiated, the immune system clears the infection through the action of T cells and B cells, simultaneously generating highly specific protective immunologic memory. We review here both the current knowledge on norovirus immunity and exciting new developments, with a focus on ongoing vaccine development work, novel cell culture systems, and advances in understanding the role of the gut microbiome. These changes reinforce the need for a better understanding of the human immune response to NoV and suggest novel hypotheses. PMID:26256101

We postulate that immunologically, both tubular structural and functional biopolymers as well as venom components can initiate innate, adaptive, as well as immediate and delayed hypersensitivity reactions that may be amenable to topical anti-inflammatory-immunomodifier therapy. The current challenge for immunotoxinologists is to deconstruct the actions of venom components to target therapeutic modalities for sting treatment.

  18. Eosinophilic alveolitis in immunologic interstitial lung disorders.

    Olivieri, D; Pesci, A; Bertorelli, G

    1990-01-01

    To analyze the role of eosinophils in alveolitis due to immunological interstitial lung disorders, 568 bronchoalveolar lavage (BAL) from 537 patients affected by 13 types of interstitial lung disease involving immunologic mechanisms were considered. An arbitrary cut-off of 4% of eosinophils in BAL was assumed. In five (idiopathic pulmonary fibrosis (IPF), allergic bronchopulmonary aspergillosis (ABPA), amiodarone-induced pneumonitis (AIP), chronic eosinophilic pneumonia (CEP), Churg-Strauss syndrome (CSS)) out of the thirteen groups we took into consideration, the level of eosinophils was greater than 4%. In CEP and CSS in particular, the arbitrary cut-off of 4% was greatly exceeded (28.9% +/- 27.4, p less than 0.01 and 33.6% +/- 14.5, p less than 0.01, respectively). In the same two groups the increase of eosinophils in BAL was isolated with a direct correlation to the number of eosinophils in blood. By contrast, the increase of eosinophils in BAL of IPF, AIP and ABPA was of lesser extent (4.7% +/- 5.7 p less than 0.01, 5.0% +/- 3.0 p less than 0.01 and 6.1% +/- 10.4 p less than 0.01, respectively) and was accompanied by an increase of neutrophils in IPF, of lymphocytes in AIP and both in ABPA. These patterns are generally defined as "mixed alveolitis." On the basis of these data we conclude that the term "eosinophilic alveolitis" should be reserved for CEP and CSS.

  19. Immunological aspects on IDDM in children.

    Ludvigsson, J

    1989-01-01

    Diabetes mellitus in childhood is connected to several immunological phenomena which per se do not prove that immunological mechanisms do cause the beta cell destruction, as such mechanisms could be just secondary. However, there is now evidence which strongly supports the autoimmune hypothesis, like the beta-cell destruction in the transplant given from a healthy twin to the diabetic monozygotic co-twin, the effect in newly-diagnosed diabetes of immunosuppression, the passive transfer in experimental animals of an immune process creating diabetes etc. Several facts such as presence of activated T-cells in the insulitis indicate that the cell-mediated immunity is important, while it is still debatable whether humoral factors, and if so which, alone could be responsible for the beta cell destruction. Recently interleukins and other lymphokines have shown to be of great interest as well as the release of free radicals. This knowledge opens new views on the possibility to put an end to or even prevent the beta cell destruction. Rough immunosuppression with cytostatics or cyclosporin has such severe side-effects that such therapy is contra-indicated at least in children. Until more specific therapies are discovered e.g. vaccination with lymphoblasts or blocking the autoantigens with monoclonal antibodies, supportive measures to protect the beta cells may be one practical way.

  20. Adverse immunologic effects of antithyroid drugs.

    1987-01-01

    Propylthiouracil and methimazole are frequently used in the management of hyperthyroidism. Two patients in whom adverse immunologic effects other than isolated agranulocytosis developed during treatment with propylthiouracil are described. A review of the literature revealed 53 similar cases over a 35-year period. Rash, fever, arthralgias and granulocytopenia were the most common manifestations. Vasculitis, particularly with cutaneous manifestations, occurs and may be fatal. The clinical evidence suggests that an immunologic mechanism is involved. A number of different autoantibodies were reported, but antinuclear antibodies were infrequent, and none of the cases met the criteria for a diagnosis of systemic lupus erythematosus. Thus, the reactions do not represent a true drug-induced lupus syndrome. Current hypotheses and experimental data regarding the cause of the reactions are reviewed. No specific clinical subgroup at high risk can be identified, and manifestations may occur at any dosage and at any time during therapy. Cross-reactivity between the two antithyroid drugs can be expected. Except for minor symptoms (e.g., mild arthralgias or transient rash), such reactions are an indication for withdrawal of the drug and the use of alternative methods to control the hyperthyroidism. In rare cases of severe vasculitis a short course of high-dose glucocorticoid therapy may be helpful. PMID:3539299

  1. Xenotransplantation: Immunological hurdles and progress toward tolerance

    Griesemer, Adam; Yamada, Kazuhiko; Sykes, Megan

    2014-01-01

    The discrepancy between organ need and organ availability represents one of the major limitations in the field of transplantation. One possible solution to this problem is xenotransplantation. Research in this field has identified several obstacles that have so far prevented the successful development of clinical xenotransplantation protocols. The main immunologic barriers include strong T cell and B cell responses to solid organ and cellular xenografts. Additionally, components of the innate immune system can mediate xenograft rejection. Here, we review these immunologic and physiologic barriers and describe some of the strategies that we and others have developed to overcome them. We also describe the development of two strategies to induce tolerance across the xenogeneic barrier, namely thymus transplantation and mixed chimerism, from their inception in rodent models through their current progress in pre-clinical large animal models. We believe that the addition of further beneficial transgenes to Gal knockout swine, combined with new therapies such as Treg administration, will allow for successful clinical application of xenotransplantation.

    Recent mechanistic insights obtained from preclinical studies and the approval of the first immunotherapies has motivated increasing number of academic investigators and pharmaceutical/biotech companies to further elucidate the role of immunity in tumor pathogenesis and to reconsider the role of immunotherapy. Additionally, technological advances (e.g., next-generation sequencing) are providing unprecedented opportunities to draw a comprehensive picture of the tumor genomics landscape and ultimately enable individualized treatment. However, the increasing complexity of the generated data and the plethora of bioinformatics methods and tools pose considerable challenges to both tumor immunologists and clinical oncologists. In this review, we describe current concepts and future challenges for the management and analysis of data for cancer immunology and immunotherapy. We first highlight publicly available databases with specific focus on cancer immunology including databases for somatic mutations and epitope databases. We then give an overview of the bioinformatics methods for the analysis of next-generation sequencing data (whole-genome and exome sequencing), epitope prediction tools as well as methods for integrative data analysis and network modeling. Mathematical models are powerful tools that can predict and explain important patterns in the genetic and clinical progression of cancer. Therefore, a survey of mathematical models for tumor evolution and tumor-immune cell interaction is included. Finally, we discuss future challenges for individualized immunotherapy and suggest how a combined computational/experimental approaches can lead to new insights into the molecular mechanisms of cancer, improved diagnosis, and prognosis of the disease and pinpoint novel therapeutic targets.

  3. Immunological aspects of liver cell transplantation

    2016-01-01

    Within the field of regenerative medicine, the liver is of major interest for adoption of regenerative strategies due to its well-known and unique regenerative capacity. Whereas therapeutic strategies such as liver resection and orthotopic liver transplantation (OLT) can be considered standards of care for the treatment of a variety of liver diseases, the concept of liver cell transplantation (LCTx) still awaits clinical breakthrough. Success of LCTx is hampered by insufficient engraftment/long-term acceptance of cellular allografts mainly due to rejection of transplanted cells. This is in contrast to the results achieved for OLT where long-term graft survival is observed on a regular basis and, hence, the liver has been deemed an immune-privileged organ. Immune responses induced by isolated hepatocytes apparently differ considerably from those observed following transplantation of solid organs and, thus, LCTx requires refined immunological strategies to improve its clinical outcome. In addition, clinical usage of LCTx but also related basic research efforts are hindered by the limited availability of high quality liver cells, strongly emphasizing the need for alternative cell sources. This review focuses on the various immunological aspects of LCTx summarizing data available not only for hepatocyte transplantation but also for transplantation of non-parenchymal liver cells and liver stem cells.

  4. Uncertainty of measurement: an immunology laboratory perspective.

    PubMed

    Beck, Sarah C; Lock, Robert J

    2015-01-01

    'Measurement uncertainty of measured quantity values' (ISO15189) requires that the laboratory shall determine the measurement uncertainty for procedures used to report measured quantity values on patients' samples. Where we have numeric data measurement uncertainty can be expressed as the standard deviation or as the co-efficient of variation. However, in immunology many of the assays are reported either as semi-quantitative (i.e. an antibody titre) or qualitative (positive or negative) results. In the latter context, measuring uncertainty is considerably more difficult. There are, however, strategies which can allow us to minimise uncertainty. A number of parameters can contribute to making measurements uncertain. These include bias, precision, standard uncertainty (expressed as standard deviation or coefficient of variation), sensitivity, specificity, repeatability, reproducibility and verification. Closely linked to these are traceability and standardisation. In this article we explore the challenges presented to immunology with regard to measurement uncertainty. Many of these challenges apply equally to other disciplines working with qualitative or semi-quantitative data.

    The open society, unlike the closed society, requires constant citizen thought and action to ensure that it will continue to survive and prosper. Today in the United States we should give particular attention to three immediate problems. We should reinvigorate our national economic health and international competitiveness, particularly by reducing our unprecedented budget deficits and reforming our tax system. We must strengthen our scientific and engineering vitality, particularly in graduate engineering education and in secondary school instruction in science and mathematics. And we should work with our allies in the free industrialized world to keep our international open society as open as possible, encouraging a flow of people and information and ideas across national boundaries while instituting sensible and efficient safeguards against leakage of critical military technology to the Soviet Union.

Moreover youth means health, age illness and senility. Until this imbalance is corrected society will be in danger of `a kind of civil war between the generations'. Society must be taught again that mortality cannot be avoided or conquered by medical science, and at the same time that `health' is not enshrined in the young alone. PMID:1177271

    A huge flow of quantitative social, demographic and behavioral data is becoming available that traces the activities and interactions of individuals, social patterns, transportation infrastructures and travel fluxes. This has caused, together with innovative computational techniques and methods for modeling social actions in hybrid (natural and artificial) societies, a qualitative change in the ways we model socio-technical systems. For the first time, society can be studied in a comprehensive fashion that addresses social and behavioral complexity. In other words we are in the position to envision the development of large data and computational cyber infrastructure defining an exploratory of society that provides quantitative anticipatory, explanatory and scenario analysis capabilities ranging from emerging infectious disease to conflict and crime surges. The goal of the exploratory of society is to provide the basic infrastructure embedding the framework of tools and knowledge needed for the design of forecast/anticipatory/crisis management approaches to socio technical systems, supporting future decision making procedures by accelerating the scientific cycle that goes from data generation to predictions.

    Immune responses are initiated by the interactions between antigen-presenting cells (APCs), such as dendritic cells (DCs), with responder cells, such as T cells, via a tight cellular contact interface called the immunological synapse. The immunological synapse is a highly organized subcellular structure that provides a platform for the presentation of antigen in major histocompatibility class I and II complexes (MHC class I and II) on the surface of the APC to receptors on the surface of the responder cells. In T cells, these contacts lead to highly polarized membrane trafficking that results in the local release of lytic granules and in the delivery and recycling of T cell receptors at the immunological synapse. Localized trafficking also occurs at the APC side of the immunological synapse, especially in DCs where antigen loaded in MHC class I and II is presented and cytokines are released specifically at the synapse. Whereas the molecular mechanisms underlying polarized membrane trafficking at the T cell side of the immunological synapse are increasingly well understood, these are still very unclear at the APC side. In this review, we discuss the organization of the APC side of the immunological synapse. We focus on the directional trafficking and release of membrane vesicles carrying MHC molecules and cytokines at the immunological synapses of DCs. We hypothesize that the specific delivery of MHC and the release of cytokines at the immunological synapse mechanistically resemble that of lytic granule release from T cells. PMID:26741354

    Medical immunology in The Netherlands is a laboratory specialism dealing with immunological analyses as well as pre- and post-analytical consultation to clinicians (clinical immunologists and other specialists) involved in patients with immune mediated diseases. The scope of medical immunology includes immunodeficiencies, autoimmune diseases, allergy, transfusion and transplantation immunology, and lymphoproliferative disorders plus the monitoring of these patients. The training, professional criteria, quality control of procedures and laboratories is well organized. As examples of the bridge function of medical immunology between laboratory (bench) and patient (bedside) the contribution of medical immunologists to diagnosis and treatment of primary immunodeficiency diseases (in particular: humoral immunodeficiencies) as well as autoantibodies (anti-citrullinated proteins in rheumatoid arthritis) are given.

    More than a century after the discovery of the complex life cycle of its causative agent, malaria remains a major health problem. Understanding mosquito-malaria interactions could lead to breakthroughs in malaria control. Novel strategies, such as the design of transgenic mosquitoes refractory to Plasmodium, or design of human vaccines emulating mosquito resistance to the parasite, require extensive knowledge of processes involved in immune responses and of microevolutionary mechanisms that create and maintain variation in immune responses in wild vector populations. The recent realization of how intimately and specifically mosquitoes and Plasmodium co-evolve in Nature is driving vector molecular biologists and evolutionary ecologists to move closer to the natural setting under the common umbrella of 'Ecological immunology'.

    In recent years new information has been collected about the immunological responses to pathogenic mycobacteria. More information on cellular and molecular responses of cells in murine and human tuberculosis has been produced and T cells' role in the production of selected cytokines has been clarified. Studies in mice have provided insight into the phases of the T cell response to virulent M. tuberculosis, the role of various T cell subsets, and the repertoire of antigens recognized by these cells. However, despite this new information, some of which has been confirmed in humans, large gaps remain in our knowledge about the immune response to this infection, particularly concerning cellular or molecular mechanisms involved in acquired protection. Even if some extrapolations from adult data can be made, large gaps in our knowledge exist on the potential immune defects in young infants who are prone to develop tuberculosis soon after infection.

    The immune system is a highly complex and dynamic system. Historically, the most common scientific and clinical practice has been to evaluate its individual components. This kind of approach cannot always expose the interconnecting pathways that control immune-system responses and does not reveal how the immune system works across multiple biological systems and scales. High-throughput technologies can be used to measure thousands of parameters of the immune system at a genome-wide scale. These system-wide surveys yield massive amounts of quantitative data that provide a means to monitor and probe immune-system function. New integrative analyses can help synthesize and transform these data into valuable biological insight. Here we review some of the computational analysis tools for high-dimensional data and how they can be applied to immunology. PMID:24448569

    Platelet immunology allows the understanding of clinical findings in a genetic and serologic basis. Blood platelets bear common antigens and same specific antigens, classified in five groups (HPA 1 to 5), that are localized on membrane glycoproteins Ia, Ib alpha, IIb and IIIa. Antiplatelet autoimmunization is generally due to IgG antibodies against membrane complexes IIb/IIIa or Ib/lX. Antiplatelet alloimmunization, clinically resulting in Posttransfusion Purpura and Neonatal Thrombocytopenia is more frequently associated with anti-IIb/IIIa antibodies, either anti-HPA-1a or HPA-1b. Finally, platelet participation in immunoallergic reactions is discussed, focusing both platelet activation by allergen itself and platelet recruitment by other inflammatory cells.

    Correlations between biochemical and immunological markers of programmed cell death (apoptosis), and the functional state of the thyroid gland (hyperthyroidism, euthyroidism, hypothyroidism) have been investigated in autoimmune thyroiditis (AT) (also known as chronic autoimmune thyroiditis). Annexin V, TRAIL and TNF-a, as well as DNA-hydrolyzing antibodies were used as the main markers. Increased levels of TRAIL were found in the serum of AT patients (hyperthyroidism>hypothyroidism>euthyroidism) compared with healthy individuals. The highest frequency of antibodies to denatured DNA (Abs-dDNA) had the highest frequency in AT patients (97%) compared with healthy controls. Among these patients, 75% had hyperthyroidism, 85% had hypothyroidism, and 84.7% had euthyroidism. Abs hydrolyzing activity demonstrated correlation dependence with symptoms of the thyroid dysfunction. PMID:27563001

    The objective of this paper is to consider several catagories of biomarkers of human pregnancy. The design of the report is to discuss useful and promising markers and techniques. Research gaps, needs, and priorities are also defined. Useful markers are mixed lymphocyte culture reactions, measures of lymphocytotoxic antibodies, histocompatibility (HLA) typing, and immunohematological evaluations. Promising markers are measures of major basic protein and early pregnancy factor, as well as determinations of trophoblast-lymphocyte cross-reactive (TLX) antigens. Promising techniques are flourescence-activated cell-sorter analysis of maternal blood for fetal and extraembryonic tissues and immunotherapy with TLX and other antigens to prevent spontaneous abortion. It is concluded that immunology has much to offer the development of biomarkers of human pregnancy.

    Systemic lupus erythematosus (SLE) is a fairly heterogeneous autoimmune disease of unknown etiology that mainly affects women in the childbearing age. SLE is a prototype type III hypersensitivity reaction in which immune complex depositions cause inflammation and tissue damage in multiple organs. Two distinct cell death pathways, apoptosis and NETosis, gained a great deal of interest among scientists, since both processes seem to be deregulated in SLE. There is growing evidence that histone modifications induced by these cell death pathways exert a central role in the induction of autoimmunity. In the current review, we discuss how abnormalities in apoptosis, NETosis, and histone modifications may lead to a break of immunological tolerance in SLE. PMID:24782867

    Shellfish (crustaceans and mollusks) have long been known as a common cause of allergic reactions to food. Like other food allergies, the allergic reactions to shellfish involve IgE-mediated Type I hypersensitivity. Biochemical and molecular studies have documented the major shrimp allergen is the muscle protein tropomyosin. Subsequent molecular cloning studies on lobsters and crabs have characterized this protein as the common allergen in crustaceans. There has also been strong immunological evidence that tropomyosin is a cross-reactive allergen among crustaceans and mollusks. This is further confirmed by recent studies on the identification of allergens in squid and abalone. The advances in the characterization of shellfish allergens will not only enhance our understanding on the physiological basis of shellfish allergy but also lay the groundwork for the development of diagnostic and therapeutic design in food allergies.

    This longitudinal study was originally designed to detect changes in the in vitro immune response of healthy subjects as a result of a psychological intervention. In this study a significant proportion, about 70%, of the immunological variability in the test results was accounted for by the differences in immunological response levels of the subjects. Apart from this between-subject-effect, a significant proportion of the variability in test results was related to the month of data sampling. The month-effect was computed in such a way that the between-subject variation was taken into account. This resulted in a more accurate estimation of the month-effect. Even after correction for the intervention, i.e. the defence of the PhD thesis, the effect of month of data sampling remains significant for mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, percentage of CD4 and CD8 cells, and for the response to the mitogens phytohaemagglutinin, pokeweed mitogen and concanavalin A as well as the results for the mixed lymphocyte culture for one pool out of three. In contrast, no significant month-effect was observed for the whole blood cell counts, for the differential white blood cell counts as determined by monoclonal antibody staining for cell surface markers CD3, CD16, TAC and OKM1, nor for the immunoglobulin IgM and IgG serum levels. Likewise the cell-mediated lympholysis activities measured against three pools of stimulator cells remained unaltered. We discuss the implications for future immunological follow-up studies of the observation that a significant proportion of the variability in immunological test results is related to differences between subjects and to the month of data sampling.

  12. Shrinking societies favor procreation.

    1999-12-01

    Low birth rates and unprecedented improvements in life expectancy had brought a shrinking society to a rapidly expanding retirement-age population. In 1999, people aged 65 and older make up 15% or more of the populations in 19 countries. Furthermore, 14 country populations are already experiencing natural decrease, and a lot more will start to decline early in the 21st century. Due to this predicament, concerned countries have created policies that may encourage more childbearing by easing the opportunity costs of raising children. Among the policies are: 1) paid maternity and paternity leaves until a child is 2-3 years; 2) free child care; 3) tax breaks for large families; 4) family housing allowance; 5) cash paid to parents for raising a child. Governments of the shrinking societies believed that these policies could influence fertility because it affects the socioeconomic setting in which childbearing decisions are made. This paper also discusses Hungary, Japan, and Sweden fertility policies. PMID:12295635

    2014-11-01

    A rapidly advancing area of ecological immunology concerns the effects of diet on animals' immunological responses to parasites and pathogens. Here, we focus on diet-mediated ecological immunology in herbivorous insects, in part because these organisms commonly experience nutritional limitations from their diets of plants. Nutritional immunology highlights nutrient-based trade-offs between immunological and other physiological processes as well as trade-offs among distinct immunological processes. This field reveals that nutrition influences the quality and quantity of immunological defense in herbivorous insects, and conversely that nutritional intake by herbivorous insects can be an adaptive response to the specific types of immune-challenge they face in the context of other physiological processes. Because the diets of herbivores challenge them physiologically with plants' secondary metabolites, another area of study analyzes constraints on immunological defense imposed by secondary metabolites of plants in the diets of herbivorous insects. Alternatively, some herbivores can use secondary metabolites as medicine against parasites or pathogens. Animal-medication theory makes an important contribution to ecological immunology by distinguishing prophylactic and therapeutic mechanisms of anti-parasite defense. Integrating ideas from animal-medication and nutritional immunology, we outline a conceptual framework in which the immunological role of the diet consists of mechanisms of prophylaxis, therapy, compensation, and combinations thereof. Then, we use this framework to organize findings from our own research on diet-mediated ecological immunology of woolly bear caterpillars. We show evidence that the woolly bear caterpillar, Grammia incorrupta (Hy. Edwards) (Lepidoptera, Erebidae, and Arctiinae), can employ both diet-mediated prophylaxis and therapy. First, increased consumption of carbohydrate-biased food prior to immune-challenge increased its melanization

    Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

The U.S. approach in 1980's, unlike its liberalist principle, has been characterized by technological protectlonism and defense-oriented policies. European Communities' approach has been more comprehensive and systematic, investing heavily telecommunication infrastructure, deregulating domestic market, and promoting cooperation of member countries. However, both of these approaches have, so far, been unable to achieve a considerable success.

    The purpose of this study was to compare the effects of hypergravity exposure (2g) with those of exposure to space flight in the Cosmos 2044 flight. To do so, rats were centrifuged continuously for 14 days. Two different experiments were carried out on tissue obtained from the centrifuged rats. In the first experiment, rat bone marrow cells were examined for their response to recombinant murine colony stimulating factor-granulocyte/monocyte (GM-CSF). In the second experiment, rat spleen and bone marrow cells were stained in with a variety of antibodies directed against cell surface antigenic markers. These cells were preserved and analyzed on a flow cytometer. The results of the studies indicated that bone marrow cells from centrifuged rats showed no significant change in response to GM-CSF as compared to bone marrow cells from control rats. Spleen cells from flown rats showed some statistically significant changes in leukocytes subset distribution, but no differences that appeared to be of biological significance. These results indicate that hypergravity did not greatly affect the same immunological parameters affected by space flight in the Cosmos 2044 mission.

    1990-01-01

    Stocks of Atlantic striped bass Morone saxatilis that were assumed to be geographically isolated during spawning showed strong antigenic differences in blood serum albumin. A discriminant function was estimated from the immunologic responses of northern (Canadian and Hudson River) and southern (Chesapeake Bay and Roanoke River) stocks to two reference antisera. The function correctly classified 92% of the northern and 95% of the southern fish in the training set. Cross-validation revealed similar percentages of correct classification for fish that were of known origin but not used to estimate the discriminant function. Monte Carlo experiments were used to evaluate the ability of the discriminant function to predict the relative contribution of northern fish in samples of various size and stock composition. Averages of predicted proportions of northern fish in the samples agreed well with actual proportions. Coefficients of variation (100 × SD/mean) in the predicted proportions ranged from 1.5 to 36% for samples of 50–400 fish that contained at least 10% northern stock. In samples that contained only 2% northern stock, however, at least 1,600 fish were required to achieve similar levels of precision.

    1992-08-01

    Conventional cytotoxic chemotherapy fails to cure the majority of patients with advanced-stage ovarian cancer, in spite of encouraging initial antitumor responses. With the emergence of drug resistance in refractory tumors, new biologic and immunologic treatment strategies are needed. Small-volume residual peritoneal disease remains an attractive target for therapeutic trials; however, even in this optimal circumstance, few regimens have yet achieved a high frequency of pathologically confirmed complete remissions. Considerable progress has been made in understanding the impact of growth factors and their receptors on tumor growth regulation and modulation of response to chemotherapy. Better characterization of the antigens recognized by monoclonal antibodies, as well as sequencing of the antibodies themselves, has permitted the rational design of therapeutic reagents that take full advantage of molecular biology techniques for production and conjugation. Important limitations of preclinical models for prediction of host toxicity are recognized, and the reasons for treatment failure in situ, as well as strategies to prevent serious dose-limiting toxicities, are being explored. Further developments in cytokine biology, adoptive cellular therapy, monoclonal antibody conjugation, and molecular biology will continue to provide a growing array of reagents for critical evaluation.

    The gut microbiota consists of a cluster of microorganisms that produces several signaling molecules of a hormonal nature which are released into the blood stream and act at distal sites. There is a growing body of evidence indicating that microbiota may be modulated by several environmental conditions, including different exercise stimulus, as well some pathologies. Enriched bacterial diversity has also been associated with improved health status and alterations in immune system, making multiple connections between host and microbiota. Experimental evidence has shown that reduced levels and variations in the bacterial community are associated with health impairments, while increased microbiota diversity improves metabolic profile and immunological responses. So far, very few controlled studies have focused on the interactions between acute or chronic exercise and the gut microbiota. However, some preliminary experimental data obtained from animal studies or probiotics studies show some interesting results at the immune level, indicating that the microbiota also acts like an endocrine organ and is sensitive to the homeostatic and physiological changes associated with exercise. Thus, our review intends to shed some light on the interaction between gut microbiota, exercise and immunomodulation.

  14. Dendritic Cells: Cellular Mediators for Immunological Tolerance

    PubMed Central

    Chung, Chun Yuen J.; Ysebaert, Dirk; Berneman, Zwi N.

    2013-01-01

    In general, immunological tolerance is acquired upon treatment with non-specific immunosuppressive drugs. This indiscriminate immunosuppression of the patient often causes serious side-effects, such as opportunistic infectious diseases. Therefore, the need for antigen-specific modulation of pathogenic immune responses is of crucial importance in the treatment of inflammatory diseases. In this perspective, dendritic cells (DCs) can have an important immune-regulatory function, besides their notorious antigen-presenting capacity. DCs appear to be essential for both central and peripheral tolerance. In the thymus, DCs are involved in clonal deletion of autoreactive immature T cells by presenting self-antigens. Additionally, tolerance is achieved by their interactions with T cells in the periphery and subsequent induction of T cell anergy, T cell deletion, and induction of regulatory T cells (Treg). Various studies have described, modulation of DC characteristics with the purpose to induce antigen-specific tolerance in autoimmune diseases, graft-versus-host-disease (GVHD), and transplantations. Promising results in animal models have prompted researchers to initiate first-in-men clinical trials. The purpose of current review is to provide an overview of the role of DCs in the immunopathogenesis of autoimmunity, as well as recent concepts of dendritic cell-based therapeutic opportunities in autoimmune diseases.

  15. Louis Pasteur, the Father of Immunology?

    Louis Pasteur is traditionally considered as the progenitor of modern immunology because of his studies in the late nineteenth century that popularized the germ theory of disease, and that introduced the hope that all infectious diseases could be prevented by prophylactic vaccination, as well as also treated by therapeutic vaccination, if applied soon enough after infection. However, Pasteur was working at the dawn of the appreciation of the microbial world, at a time when the notion of such a thing as an immune system did not exist, certainly not as we know it today, more than 130 years later. Accordingly, why was Pasteur such a genius as to discern how the immune system functions to protect us against invasion by the microbial world when no one had even made the distinction between fungi, bacteria, or viruses, and no one had formulated any theories of immunity. A careful reading of Pasteur’s presentations to the Academy of Sciences reveals that Pasteur was entirely mistaken as to how immunity occurs, in that he reasoned, as a good microbiologist would, that appropriately attenuated microbes would deplete the host of vital trace nutrients absolutely required for their viability and growth, and not an active response on the part of the host. Even so, he focused attention on immunity, preparing the ground for others who followed. This review chronicles Pasteur’s remarkable metamorphosis from organic chemist to microbiologist to immunologist, and from basic science to medicine. PMID:22566949

    Our results show that a lack of taurine in the diet of cats results in a significant leukopenia, a shift in the percentage of polymorphonuclear and mononuclear leukocytes, an increase in the absolute count of mononuclear leukocytes, and a change in the sedimentation characteristics of white cells. Functional studies of polymorphonuclear cells isolated from cats fed taurine-free diets show a significant decrease in the respiratory burst as measured by chemiluminescence as well as a decrease in phagocytosis of Staphylococcus epidermis compared to cats fed the same diet containing taurine. In addition, serum gamma globulin in cats fed taurine-free diets was significantly increased compared to taurine-supplemented cats, indicating that other immune cells may be affected by taurine deficiency. Histological examination of lymph nodes and spleen revealed regression of follicular centers with depletion of reticular cells, mature and immature lymphocytes (B cell areas), as well as mild extravascular hemolysis. These results indicate that there are profound immunologic consequences in cats with prolonged taurine deficiency. PMID:2319206

    The use of biodegradable magnesium implants in pediatric trauma surgery would render surgical interventions for implant removal after tissue healing unnecessary, thereby preventing stress to the children and reducing therapy costs. In this study, we report on the immunological response to biodegradable magnesium implants—as an important aspect in evaluating biocompatibility—tested in a growing rat model. The focus of this study was to investigate the response of the innate immune system to either fast or slow degrading magnesium pins, which were implanted into the femoral bones of 5-week-old rats. The main alloying element of the fast-degrading alloy (ZX50) was Zn, while it was Y in the slow-degrading implant (WZ21). Our results demonstrate that degrading magnesium implants beneficially influence the immune system, especially in the first postoperative weeks but also during tissue healing and early bone remodeling. However, rodents with WZ21 pins showed a slightly decreased phagocytic ability during bone remodeling when the degradation rate reached its maximum. This may be due to the high release rate of the rare earth-element yttrium, which is potentially toxic. From our results we conclude that magnesium implants have a beneficial effect on the innate immune system but that there are some concerns regarding the use of yttrium-alloyed magnesium implants, especially in pediatric patients.

  18. Tubulin evolution: an electrophoretic and immunological analysis.

    Adoutte, A; Claisse, M; Cance, J

    1984-03-01

    This paper summarizes a survey of the electrophoretic behavior of the tubulins of 23 species (mostly protists) as well as their reactivity towards 4 anti-tubulin antibodies (raised against two ciliate tubulins and two vertebrate ones). Some generalizations concerning the relative migration rates of alpha VS beta tubulin could be made, in particular the alpha/beta inversion, first described in Physarum was extended to several ciliates. Antivertebrate tubulin antibodies displayed a very broad spectrum of reactions, reacting with virtually all the species tested. They appear to correspond to auto-antibodies no exclusively directed against species specific determinants. In contrast, the two anti-ciliate tubulin antibodies displayed a narrow species specificity reacting only with a limited subset of protists. They were shown to be specific for a small number of immunological determinants present on ciliate tubulins. This allowed a rough evaluation of evolutionary relatedness between the various groups of protists analyzed. The results are discussed within the framework of a number of published phyllogenies and shown to be in striking agreement with some of the schemes.

  20. Immunological characterization of plant ornithine transcarbamylases

    Pea (Pisum sativum L.) ornithine transcarbamylase (OTC) antisera were used to investigate the immunological relatedness of several plant and animal OTC enzymes. The antisera immunoprecipitated OTC activity in all monocot and dicot species tested, and sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis of immunoprecipitated protein revealed monomeric proteins ranging from 35,200 to 36,800 daltons in size. Pea OTC antisera did not recognize mammalian OTC protein. OTC activity and protein levels detected on sodium dodecyl sulfate polyacrylamide gel electrophoresis immunoblots from homogenates of green leaf, etiolated epicotyl and cotyledon, and root tissues of pea were poorly correlated. This might result from differences in amounts of enzymatically active OTC protein in the homogenates. Alternatively, the antisera may fail to recognize different isozyme forms of OTC, which have been reported for some plant species. A putative cytosolic precursor OTC (pOTC) polypeptide exhibiting and Mr = 39,500 to 40,000 daltons was immunoprecipitated from in vitro translation mixtures of total pea leaf poly(A)+ RNA. The size of the pOTC polypeptide, as compared with mature OTC monomer (36,000 daltons), suggests that a 4 kilodalton N-terminal leader sequence, like that responsible for mitochondrial targeting of the mammalian enzyme, may be involved in organellar import of the plant enzyme.

    Although bone marrow is the main source, mesenchymal stem cells have already been isolated from various other tissues, such as the liver, pancreas, adipose tissue, peripheral blood and dental pulp. These plastic adherent cells are morphologically similar to fibroblasts and have a high proliferative potential. This special group of cells possesses two essential characteristics: self-renewal and differentiation, with appropriate stimuli, into various cell types. Mesenchymal stem cells are considered immunologically privileged, since they do not express costimulatory molecules, required for complete T cell activation, on their surface. Several studies have shown that these cells exert an immunosuppressive effect on cells from both innate and acquired immunity systems. Mesenchymal stem cells can regulate the immune response in vitro by inhibiting the maturation of dendritic cells, as well as by suppressing the proliferation and function of T and B lymphocytes and natural killer cells. These special properties of mesenchymal stem cells make them a promising strategy in the treatment of immune mediated disorders, such as graft-versus-host disease and autoimmune diseases, as well as in regenerative medicine. The understanding of immune regulation mechanisms of mesenchymal stem cells, and also those involved in the differentiation of these cells in various lineages is primordial for their successful and safe application in different areas of medicine.

    2014-10-01

    This paper resolves the long standing debate as to the proper time scale <τ> of the onset of the immunological synapse bond, the noncovalent chemical bond defining the immune pathways involving T cells and antigen presenting cells. Results from our model calculations show <τ> to be of the order of seconds instead of minutes. Close to the linearly stable regime, we show that in between the two critical spatial thresholds defined by the integrin:ligand pair (Δ2˜ 40-45 nm) and the T-cell receptor TCR:peptide-major-histocompatibility-complex pMHC bond (Δ1˜ 14-15 nm), <τ> grows monotonically with increasing coreceptor bond length separation δ (= Δ2-Δ1˜ 26-30 nm) while <τ> decays with Δ1 for fixed Δ2. The nonuniversal δ-dependent power-law structure of the probability density function further explains why only the TCR:pMHC bond is a likely candidate to form a stable synapse.

    1994-01-01

    The endogenous uveitis is essentially an immunologic disease, although it has a very variable immunology. During the immune response are implied the reactions of tardive hypersensibility (by immune complexes), hypersensibility through antibodies produced intraocularly or transported by the overall circulation and rarely, immediate hypersensibility reaction. The absence of lymphatics in the eye and of the antigenic cells in the tissues which limit the anterior chamber, implies an active, deviated immunity response, denoted by the term ACAID.

    "Nothing in science has any value to society if it is not communicated." So goes the 1952 quote from Anne Roe, the noted twentieth century American psychologist and writer. She went on to say that "scientists are beginning to learn their social obligations", and now over 60 years later there is certainly evidence to support her assertions. As scientists, by communicating our research to the general public we not only better inform the tax payer where their money is being spent, but are also able to help put into context the topical environmental challenges and issues that society faces, as well as inspiring a whole new generation of future scientists. This process of communication is very much a two-way street; by presenting our work to people outside of our usual spheres of contemporaries, we expose ourselves to alternative thoughts and insights that can inspire us, as scientists, to take another look at our research from angles that we had never before considered. This work presents the results and experiences from a number of public engagement and outreach activities across the UK, in which geoscientists engaged and interacted with members of the general public. These include the design and implementation of Raspberry Pi based outreach activities for several hundred high school students; the process of running a successful podcast (http://thebarometer.podbean.com); hosting and participating in science events for thousands of members of the general public (e.g. http://www.manchestersciencefestival.com and http://sse.royalsociety.org/2013); and creating a citizen science activity that involved primary school children from across the UK. In communicating their research it is imperative that scientists interact with their audience in an effective and engaging manner, whether in an international conference, a classroom, or indeed down the pub. This work also presents a discussion of how these skills can be developed at an early stage in the careers of a research

    On September 27, 2015 the 20th annual Alcohol and Immunology Research Interest Group (AIRIG) meeting was held as a satellite symposium at the annual meeting of the Society for Leukocyte Biology in Raleigh, NC. The 2015 meeting focused broadly on adverse effects of alcohol and alcohol-use disorders in multiple organ systems. Divided into two plenary sessions, AIRIG opened with the topic of pulmonary inflammation as a result of alcohol consumption, which was followed by alcohol's effect on multiple organs, including the brain and liver. With presentations showing the diverse range of underlying pathology and mechanisms associated with multiple organs as a result of alcohol consumption, AIRIG emphasized the importance of continued alcohol research, as its detrimental consequences are not limited to one or even two organs, but rather extend to the entire host as a whole.

    As health care changes under the pressures of restraint and constraint our vision of the future of medical education should be based on the medical school's responsibility to the community. The medical school is "an academy in the community": as an academy, it fosters the highest standards in education and research; as an institution in the community, it seeks to improve public health and alleviate suffering. The author argues that to better achieve these goals medical schools need to become more responsible and responsive to the population they serve. Medical schools have been slow to accept fully the social contract by which, in return for their service to society, they enjoy special rights and benefits. This contract requires that medical educators listen to the public, talk honestly and constructively with government representatives and assess the needs and expectations of the community.

This is followed by a summary review of the proposed solutions identified in other papers in this special issue of The Behavior Analyst, most of which relate to either better marketing of either the behavior analytic process or the results achieved as a consequence. One paper proposes a more broad conception of behavior analysis. This paper endorses the solutions identified in previous papers and then goes on to propose an even more broad conception of behavior analysis and makes the point that behavior analysis is unlikely to flourish unless behavior analysts understand a good deal more about the cultural and other contextual features of the environments in which they work.

    Mr. Brown feels the world needs a land ethic to guide resource planning and an ecological theology to serve as custodian over the thinning topsoil, spreading desert, and growing population. In a sustainable society, durability and recycling replace obsolescence as the economy's organizing principle, and virgin materials are seen not as a primary source of material but as a supplement to the existing stock. The key to national security is sustainability. If the biological underpinnings of the global economic system cannot be secured, and if new energy sources and systems are not in place as the oil wells go dry, then economic disruptions and breakdowns are inevitable. In effect, the traditional military concept of national security grows less adequate in the face of growing non-military threats. 154 notes and references, 6 figures, 41 tables.

    Hypocellular or hypoplastic myelodysplastic syndromes (HMDS) are a distinct subgroup accounting for 10–15% of all MDS patients, that are characterized by the presence of bone marrow (BM) hypocellularity, various degree of dysmyelopoiesis and sometimes abnormal karyotype. Laboratory and clinical evidence suggest that HMDS share several immune-mediated pathogenic mechanisms with acquired idiopathic aplastic anemia (AA). Different immune-mediated mechanisms have been documented in the damage of marrow hematopoietic progenitors occurring in HMDS; they include oligoclonal expansion of cytotoxic T lymphocytes (CTLs), polyclonal expansion of various subtypes of T helper lymphocytes, overexpression of FAS-L and of the TNF–related apoptosis-inducing ligand (TRAIL), underexpression of Flice-like inhibitory protein long isoform (FLIPL) in marrow cells as well as higher release of Th1 cytokines, such as interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α). It has also been documented that some HMDS patients have higher frequency of polymorphisms linked both to high production of proinflammatory cytokines such as TNF-α and transforming growth factor-β and to the inhibition of T-cell mediated immune responses such as interleukin-10, further suggesting that immune-mediated mechanisms similar to those seen in AA patients may also operate in HMDS. Clinically, the strongest evidence for immune–mediated hematopoietic suppression in some HMDS is the response to immunosuppression including mainly cyclosporine, anti-thymocyte globulin and/or cyclosporine, or alemtuzumab. Here we review all these immune mechanisms as well as the influence of this deranged cellular and humoral immunologic mileau on the initiation and possible progression of MDS. All these observations are pivotal not only for a better understanding of MDS pathophysiology, but also for their immediate clinical implications, eventually leading to the identification of MDS patients who may benefit from

    Animals that hunt and scavenge are often exposed to a broad array of pathogens. Theory predicts the immune systems of animals specialized for scavenging should have been molded by selective pressures associated with surviving microbial assaults from their food. Spotted hyenas (Crocuta crocuta) are capable hunters that have recently descended from carrion feeding ancestors. Hyenas have been documented to survive anthrax and rabies infections, and outbreaks of several other viral diseases that decimated populations of sympatric carnivores.

Domestic cats (Felis catus) are the closest phylogenetic relatives of hyenas that have been studied in detail immunologically, and we hypothesized that anti-cat isotype-specific antibodies would cross react with hyena immunoglobulin epitopes. We used ELISA and Western blots to test isotype-specific anti-feline antibodies for specific cross-reaction to hyena Ig epitopes. Molecular weights of heavy (IgA, IgG, IgM) and light chains of hyena immunoglobulins were determined by protein electrophoresis, and as expected, they were found to be similar to feline immunoglobulins. In order to further validate the cross-reactivity of the anti-feline antibodies and document the hyena humoral response, eight spotted hyenas were immunized with dinitrophenol conjugated keyhole limpet hemocyanin (DNP-KLH) and serum anti-DNP responses were monitored by enzyme-linked immunosorbent assay (ELISA) for one year. The full array of isotype-specific antibodies identified here will allow veterinarians and other researchers to thoroughly investigate the hyena antibody response, and can be used in future studies to test hypotheses about pathogen exposure and immune function in this species.

    Animals that hunt and scavenge are often exposed to a broad array of pathogens. Theory predicts the immune systems of animals specialized for scavenging should have been molded by selective pressures associated with surviving microbial assaults from their food. Spotted hyenas (Crocuta crocuta) are capable hunters that have recently descended from carrion feeding ancestors. Hyenas have been documented to survive anthrax and rabies infections, and outbreaks of several other viral diseases that decimated populations of sympatric carnivores. In light of the extreme disease resistance manifested by spotted hyenas, our objective was to identify tools available for studying immune function in spotted hyenas and use these tools to document the hyena antibody response to immunization.

  12. The immunological landscape in necrotising enterocolitis.

    2016-01-01

    Necrotising enterocolitis (NEC) is an uncommon, but devastating intestinal inflammatory disease that predominantly affects preterm infants. NEC is sometimes dubbed the spectre of neonatal intensive care units, as its onset is insidiously non-specific, and once the disease manifests, the damage inflicted on the baby's intestine is already disastrous. Subsequent sepsis and multi-organ failure entail a mortality of up to 65%. Development of effective treatments for NEC has stagnated, largely because of our lack of understanding of NEC pathogenesis. It is clear, however, that NEC is driven by a profoundly dysregulated immune system. NEC is associated with local increases in pro-inflammatory mediators, e.g. Toll-like receptor (TLR) 4, nuclear factor-κB, tumour necrosis factor, platelet-activating factor (PAF), interleukin (IL)-18, interferon-gamma, IL-6, IL-8 and IL-1β. Deficiencies in counter-regulatory mechanisms, including IL-1 receptor antagonist (IL-1Ra), TLR9, PAF-acetylhydrolase, transforming growth factor beta (TGF-β)1&2, IL-10 and regulatory T cells likely facilitate a pro-inflammatory milieu in the NEC-afflicted intestine. There is insufficient evidence to conclude a predominance of an adaptive Th1-, Th2- or Th17-response in the disease. Our understanding of the accompanying regulation of systemic immunity remains poor; however, IL-1Ra, IL-6, IL-8 and TGF-β1 show promise as biomarkers. Here, we chart the emerging immunological landscape that underpins NEC by reviewing the involvement and potential clinical implications of innate and adaptive immune mediators and their regulation in NEC.

    In October 2005, as the United States still was reeling from Hurricane Katrina in August and as the alphabet was too short to contain all of that year's named Atlantic tropical storms (Hurricane Wilma was forming near Jamaica), a timely workshop in Bermuda focused on climate extremes and society (see Eos, 87(3), 25, 17 January 2006). This edited volume, which corresponds roughly to the presentations given at that workshop, offers a fascinating look at the critically important intersection of acute climate stress and human vulnerabilities. A changing climate affects humans and other living things not through the variable that most robustly demonstrates the role of rising greenhouse gases—globally averaged temperature—but through local changes, especially changes in extremes. The first part of this book, “Defining and modeling the nature of weather and climate extremes,” focuses on natural science. The second part, “Impacts of weather and climate extremes,” focuses on societal impacts and responses, emphasizing an insurance industry perspective because a primary sponsor of the workshop was the Risk Prediction Initiative, whose aim is to “support scientific research on topics of interest to its sponsors” (p. 320).

  17. Nonself help: how immunology might reframe the Enlightenment.

    PubMed

    Napier, A David

    2012-01-01

    The classical immunological paradigm is predicated on the body's ability to recognize and eliminate “nonself.” However, the “self–nonself” model has yet to facilitate any resolution of the field's major concerns, and may thus prove to be of limited use. Merely discarding it is no solution, as the juxtaposition of “self” and “nonself” persists in research, in clinical settings, and in everyday practice despite the best efforts of theoretical immunologists. Instead, the very conception of “selfhood” may prove to be key. Replacing immunology's prior and persistent “self” with less static concepts derived from non-Western contexts not only resolves immunology's famous paradoxes but also offers a new and more accurate model that allows immunology to reframe what may become an outmoded Enlightenment construct of “self.” In such a new paradigm, immunology's well-known system of protection and defense is replaced with a view in which nonself becomes less the body's enemy than its primary mechanism for the creative assimilation of difference. This incorporative model—in which the “immune system” functions more as a search engine than as an expeller of difference—both resolves outstanding paradoxes, and complies more accurately with contemporary knowledge and research practice.

    Harber, M; Sundstedt, A; Wraith, D

    2000-11-27

    Current immunosuppression protocols, although often effective, are nonspecific and therefore hazardous. Consequently, immunological tolerance that is antigen specific and does not globally depress the patient's immune system has become one of the Holy Grails of immunology. Since the discovery that cytokines have immunomodulatory effects, extensive research has investigated the potential of these molecules to induce and maintain specific immunological tolerance in the context of transplantation, allergy and autoimmunity. In this article, we review the possible mechanisms by which cytokines can modulate the immune response and the animal models that frequently confound the theory that a single cytokine, or group of cytokines, can induce tolerance in a predictable manner. Finally, we discuss the role of cytokines at a paracrine level, particularly in the context of inducing and maintaining antigen-specific, regulatory T cells with the clinical potential to suppress specific immune responses.

    2014-06-15

    In veterinary animal species, vaccines are the primary tool for disease prevention, a key tool for treatment of infection, and essential for helping maintain animal welfare and productivity. Traditional vaccine development by trial-and-error has achieved many successes. However, effective vaccines that provide solid cross-protective immunity with excellent safety are still needed for many diseases. The path to development of vaccines against difficult pathogens requires recognition of uniquely evolved immunological interactions of individual animal hosts and their specific pathogens. Here, general principles that currently guide veterinary immunology and vaccinology research are reviewed, with an emphasis on examples from swine. Advances in genomics and proteomics now provide the community with powerful tools for elucidation of regulatory and effector mechanisms of protective immunity that provide new opportunities for successful translation of immunological discoveries into safe and effective vaccines.

  8. Development of the concept of immunologic specificity: IV.

    PubMed

    Silverstein, A M

    1983-09-01

    We have attempted, in this series of essays on the development of the concept of immunologic specificity, to trace the history of one of the most central ideas in immunology (and indeed in biology in general). The result must be viewed as preliminary and incomplete and as an invitation to others to add, to amend, and even to disprove. Nevertheless, several interesting conclusions may be drawn, which reveal much about the workings of immunology in particular, and perhaps science in general. First, the roots of any important scientific concept (such as that of immunologic specificity) do not grow in isolation; they draw nourishment from many other disciplines. Similarly, the growth of an important concept within a given discipline will have far-reaching implications and fruits for other fields of science. Second, we may note a marked change in the manner in which immunology is currently practiced, compared with that of the end of the last century. The quantum leaps forward in funding, in numbers of scientists, and in masses of crucial data have not been without a certain cost--the substantial reduction in elegant personal style that characterized so many of our scientific forebears, and that makes so pleasant the reading of their reports. Finally, we see again and again how much his philosophical bases and disciplinary upbringing determine a scientist's approach, the questions that he asks, and the type of answers he will accept. Throughout much of immunology's history, as Jerne put it so well (44), cis- and trans-immunologists hardly spoke to one another. Or rather, a cis-immunologist sometimes spoke to a trans-immunologist, but the latter rarely answered! Fortunately, one of the attributes of scientific progress is a merging of these disparate languages, and eventual mutual comprehension.

    Non-immunological defence mechanisms represent an important line of intestinal defence in addition to humoral and cellular immunity. This review summarises the evidence for the role of the non-immunological defence system. Protective factors that have been amply documented are gastric juice, intestinal motility, and intestinal flora. Components of pancreatic juice, lysozyme, and epithelial cell turnover may also be involved. Special attention is given to gastric acid, infection with Helicobacter pylori, and hypochlorhydria and their association with infectious diarrhoea. Epidemic hypochlorhydria is discussed since this increases sensitivity to intestinal infections in third world countries. PMID:1644343

    Chronic beryllium disease (CBD) is a debilitating, incurable, and often fatal disease that is caused by the inhalation of beryllium particulates. The growing use of beryllium in the modern world, in products ranging from computers to dental prosthetics (390 tons of beryllium in the US in the year 2000) necessitates a molecular based understanding of the disease in order to prevent and cure CBD. We have investigated the molecular basis of CBD at Los Alamos National Laboratory during the past six years, employing a multidisciplinary approach of bioinorganic chemistry and immunology. The results of this work, including speciation, inhalation and dissolution, and immunology will be discussed. PMID:18566702

    Statin-related myopathy (SRM) undermines drug adherence that is critical for achieving the benefits of lipid-lowering therapy. While the exact mechanism of SRM remains largely unknown, recent evidence supports specific genetic and immunologic influence on the development of intolerance. Genes of interest include those involved in the pharmacokinetics of statin response (i.e. drug metabolism, uptake transporters, and efflux transporters), pharmacodynamics (i.e. drug toxicity and immune-mediated myopathy), and gene expression. We examine the influence of genetic and immunologic variation on the pharmacokinetics, pharmacodynamics, and gene expression of SRM.

(2) Of the different immunological techniques that of antibody titration by the hemagglutination method is an easy, sensitive test, but only if the Goldmann-Witner ratio is calculated. By this technique, the diagnosis of herpetic infection can be made in unusual clinical presentations or old cases in which all specificity had disappeared.

    Among the various scientific fields covered in the area of hygiene such as environmental medicine, epidemiology, public health and preventive medicine, we are investigating the immunological effects of fibrous and particulate substances in the environment and work surroundings, such as asbestos fibers and silica particles. In addition to these studies, we have attempted to construct health-promoting living conditions. Thus, in this review we will summarize our investigations regarding the (1) immunological effects of asbestos fibers, (2) immunological effects of silica particles, and (3) construction of a health-promoting living environment. This review article summarizes the 2014 Japanese Society for Hygiene (JSH) Award Lecture of the 85th Annual Meeting of the JSH entitled "Environmental health effects: immunological effects of fibrous and particulate matter and establishment of health-promoting environments" presented by the first author of this manuscript, Prof. Otsuki, Department of Hygiene, Kawasaki Medical School, Kurashiki, Japan, the recipient of the 2014 JSH award. The results of our experiments can be summarized as follows: (1) asbestos fibers reduce anti-tumor immunity, (2) silica particles chronically activate responder and regulatory T cells causing an unbalance of these two populations of T helper cells, which may contribute to the development of autoimmune disorders frequently complicating silicosis, and (3) living conditions to enhance natural killer cell activity were developed, which may promote the prevention of cancers and diminish symptoms of virus infections.

  14. Big Data Analytics in Immunology: A Knowledge-Based Approach

    With the vast amount of immunological data available, immunology research is entering the big data era. These data vary in granularity, quality, and complexity and are stored in various formats, including publications, technical reports, and databases. The challenge is to make the transition from data to actionable knowledge and wisdom and bridge the knowledge gap and application gap. We report a knowledge-based approach based on a framework called KB-builder that facilitates data mining by enabling fast development and deployment of web-accessible immunological data knowledge warehouses. Immunological knowledge discovery relies heavily on both the availability of accurate, up-to-date, and well-organized data and the proper analytics tools. We propose the use of knowledge-based approaches by developing knowledgebases combining well-annotated data with specialized analytical tools and integrating them into analytical workflow. A set of well-defined workflow types with rich summarization and visualization capacity facilitates the transformation from data to critical information and knowledge. By using KB-builder, we enabled streamlining of normally time-consuming processes of database development. The knowledgebases built using KB-builder will speed up rational vaccine design by providing accurate and well-annotated data coupled with tailored computational analysis tools and workflow.

  19. The immunological relatedness of neurofilament proteins of higher vertebrates.

    PubMed

    Shaw, G; Debus, E; Weber, K

    1984-05-01

    We prepared intermediate filaments from the nervous system of several different species, representing mammals, birds and reptiles. These were examined using a panel of polyclonal and monoclonal antibodies originally raised against pig or rat neurofilament proteins. All species studied possessed a single major protein of apparent molecular weight between 68 K and 75 K immunologically related to the lowest molecular weight rat and pig neurofilament protein. All birds and mammals possessed two proteins immunologically related respectively to the pig and rat middle and high molecular weight neurofilament proteins. These data show that the neurofilament triplet proteins represent an evolutionarily conserved three member protein family in birds and mammals, and allow us to suggest a new nomenclature for these three homologous proteins: "H" for the heaviest subunit, "M" for the middle subunit and "L" for the lightest subunit. We found that many monoclonal antibodies stained both the H- and M-proteins of all mammalian and avian species examined, suggesting a close immunological relatedness between these two proteins. The reptiles examined appeared to have only one high molecular weight protein, which was immunologically related to both of the high molecular weight mammalian and avian neurofilament proteins. We also noted a curious situation in neurofilament preparations derived from cows. Both the highest and the middle cow neurofilament proteins were stained by all antibodies which were specific solely for the high molecular weight protein in other species.

  6. Regulation of immunological and inflammatory functions by biotin.

    PubMed

    Kuroishi, Toshinobu

    2015-12-01

    Biotin is a water-soluble B-complex vitamin and is well-known as a co-factor for 5 indispensable carboxylases. Holocarboxylase synthetase (HLCS) catalyzes the biotinylation of carboxylases and other proteins, whereas biotinidase catalyzes the release of biotin from biotinylated peptides. Previous studies have reported that nutritional biotin deficiency and genetic defects in either HLCS or biotinidase induces cutaneous inflammation and immunological disorders. Since biotin-dependent carboxylases involve various cellular metabolic pathways including gluconeogenesis, fatty acid synthesis, and the metabolism of branched-chain amino acids and odd-chain fatty acids, metabolic abnormalities may play important roles in immunological and inflammatory disorders caused by biotin deficiency. Transcriptional factors, including NF-κB and Sp1/3, are also affected by the status of biotin, indicating that biotin regulates immunological and inflammatory functions independently of biotin-dependent carboxylases. An in-vivo analysis with a murine model revealed the therapeutic effects of biotin supplementation on metal allergies. The novel roles of biotinylated proteins and their related enzymes have recently been reported. Non-carboxylase biotinylated proteins induce chemokine production. HLCS is a nuclear protein involved in epigenetic and chromatin regulation. In this review, comprehensive knowledge on the regulation of immunological and inflammatory functions by biotin and its potential as a therapeutic agent is discussed. PMID:26168302

    2014-01-01

    With the vast amount of immunological data available, immunology research is entering the big data era. These data vary in granularity, quality, and complexity and are stored in various formats, including publications, technical reports, and databases. The challenge is to make the transition from data to actionable knowledge and wisdom and bridge the knowledge gap and application gap. We report a knowledge-based approach based on a framework called KB-builder that facilitates data mining by enabling fast development and deployment of web-accessible immunological data knowledge warehouses. Immunological knowledge discovery relies heavily on both the availability of accurate, up-to-date, and well-organized data and the proper analytics tools. We propose the use of knowledge-based approaches by developing knowledgebases combining well-annotated data with specialized analytical tools and integrating them into analytical workflow. A set of well-defined workflow types with rich summarization and visualization capacity facilitates the transformation from data to critical information and knowledge. By using KB-builder, we enabled streamlining of normally time-consuming processes of database development. The knowledgebases built using KB-builder will speed up rational vaccine design by providing accurate and well-annotated data coupled with tailored computational analysis tools and workflow.

    Immunology offers an unprecedented opportunity for the science-driven development of therapeutics. The successes of antibodies to the immunomodulatory receptor CTLA-4 and blockade of the immunoinhibitory receptor PD-1 in cancer immunotherapy, from gene discovery to patient benefit, have created a paradigm for driving such endeavors.

    The aim of the yearly National Congress of the Italian Society of Virology (SIV) is to promote the discussion between senior and younger researchers to improve the knowledge and scientific collaboration among the various areas of Virology. The invited and selected lecturers of the fourth National Congress of SIV covered the following topics: general Virology and viral Genetics; virus host interactions and pathogenesis; viral immunology and vaccines; emerging and re-emerging viral diseases; antiviral therapy; innovative diagnostics; viral biotechnologies and gene therapy. As in the previous edition (Salata and Palù, 2004 J Cell Physiol 199:171-173), a specific topic was thoroughly covered in a roundtable. In this edition the overviewed topic was HCV, from epidemiology and genetic variability to immunology and antiviral therapy. The final program can be found at the web site http://www.siv-virologia.it. A summary of the oral presentations of the 2004 meeting is reported.

  17. The dynamics of conceptual change in twentieth century immunology.

    PubMed

    Silverstein, A M

    1991-02-01

    I have attempted here to define three distinct eras in the 110-year history of the discipline of immunology. The first, extending from 1880 to about the First World War, centered around the new bacteriology and infectious diseases, and had a distinctly medical orientation. Several of the components of the original research program in immunology failed to maintain their original momentum or to fulfill their initial high promise, and went into decline. These include the development of new vaccines, serotherapeutic approaches, the study of cellular immunity, and the study of diseases that might be mediated by cytotoxic antibodies. Two other subprograms followed a somewhat different course; the study of anaphylaxis and related diseases passed primarily into the hands of clinical allergists, while the development and adaptation of serodiagnostic techniques passed into the hands of the new discipline of serology, both fields out of the mainstream of post-World War I immunology. As interest in the components of the old program was falling away, there developed a new area of interest in immunology. Leadership in the field devolved upon a new group of individuals with a predominantly chemical orientation to the study of antigens and antibodies, who pursued a research program and developed a theoretical base that reflected this orientation well. It may be interesting to examine more closely the forces responsible for this shift in emphasis. When interest in the old areas waned, the medically oriented practitioners did not switch to more immunochemical lines, but went in other directions. Karl Landsteiner was the only prominent "old-timer" who contributed significantly to the newer immunology, and it was his work that set the tone and attracted the new generation of immunochemists who became the reigning Denkkollektiv. A science does not change its precepts and approaches spontaneously; it is moved to the new position by those who explore fertile new areas. This is not to say

  18. Epidemiological, clinical and immunological aspects of neuromyelitis optica (NMO).

    PubMed

    Asgari, Nasrin

    2013-10-01

    Neuromyelitis optica (NMO) is an inflammatory demyelinating disease (IDD) of the central nervous system (CNS) and probably the most common non-multiple sclerosis (MS) CNS IDD. Serum immunoglobulin G autoantibodies have been identified in the majority of NMO patients with the water channel aquaporin-4 (AQP4) as their main target autoantigen. Previous studies have suggested ethnicity-based prevalence differences of NMO. The genetic background for these putative differences is not known. An HLA-association with NMO has been identified, but the association is not very pronounced. Human and experimental studies support that anti-AQP4 antibodies/NMO-IgG are involved in the pathogenesis of NMO. Previous experimental animal models have reported induction of NMO-like histopathology in animals by transfer of human anti-AQP4 antibodies/NMO-IgG. A main goal of this PhD thesis was to perform a population-based study in a predominantly Caucasian population (in the Region of Southern Denmark) to estimate the incidence and prevalence of NMO and describe the clinical phenotypes in this population. Furthermore the aims were to investigate whether autoimmunity underlies or contributes to the pathogenesis of NMO with specific clinical, immunogenetic and experimental perspectives. The yearly incidence rate of NMO in the population was estimated to be 0.4 per 105 person-years (95% CI 0.30-0.54) and the prevalence was 4.4 per 105 (95% CI 3.1-5.7). The results indicated that NMO is more common in a Caucasian population than earlier believed. Clinical, radiologic and serological data were reviewed in order to establish the diagnostic accuracy of anti-AQP4 antibodies/NMO-IgG for specific syndromes in NMO. We observed assay characteristics with a sensitivity of 62% and a specificity of 100%. The diagnosis of NMO based on either the Wingerchuk 2006 criteria or the United States National Multiple Sclerosis Society 2008 criteria could be made purely on clinical grounds in a high proportion (64
