The aim of this study was to examine whether short- and long-term gene transfer of Ca2+ handling proteins restore left ventricular (LV) mechanoenergetics in aortic banding-induced failing hearts. Aortic banded rats received recombinant adenoviruses carrying sarcoplasmic reticulum Ca2+-ATPase (SERCA2a) (Banding+SERCA), parvalbumin ...

BackgroundPARV4 is a new member of the Parvoviridae family not closely related to any of the known human parvoviruses. Viremia seems to be a hallmark of PARV4 infection and viral DNA persistence has been demonstrated in a few tissues. Till now, PARV4 has not been associated with any disease and its prevalence in human population has ...
PARV4 is a recently discovered human parvovirus widely distributed in injecting drug users in the USA and Europe, particularly in those co-infected with human immunodeficiency virus (HIV). Like parvovirus B19, PARV4 persists in previously exposed individuals. In bone marrow and lymphoid tissue, PARV4 sequences were detected in two ...

BackgroundPARV4 is a human parvovirus first detected and cloned from an individual with a HIV seroconversion-like illness and which subsequently persists in lymphoid tissue and bone marrow. In contrast to B19V, PARV4 infections are most frequently detected in injecting drug users (IDUs), particularly those co-infected with HIV-1. To investigate its ...
Background.?Parvovirus 4 (PARV4) is a recently identified human virus that has been found in livers of patients infected with hepatitis C virus (HCV) and in bone marrow of individuals infected with human immunodeficiency virus (HIV). T cells are important in controlling viruses but may also contribute to disease pathogenesis. The interaction of PARV4 with ...

AAV1 and AAV6 are two closely related AAV serotypes. In the present study, we found AAV6 was more efficient in transducing mouse lower airway epithelia in vitro and in vivo than AAV1. To further explore the mechanism of this difference, we found that significantly more AAV1 ...
We have previously shown that adeno-associated virus (AAV) grown in KB cells with a helper adenovirus, produced several classes of particles defined by their buoyant density in CsCl. The predominant density classes were referred to as AAV(1.45), AAV(1.41), AAV (1.35), and AAV(1.32), ...

Human parvovirus 4 (PARV4), a recently discovered parvovirus found exclusively in human plasma and liver tissue, was considered phylogenetically distinct from other parvoviruses. Here, we report the discovery of two novel parvoviruses closely related to PARV4, porcine hokovirus (PHoV) and bovine hokovirus (BHoV), from porcine and bovine samples in Hong ...

We have developed an improved method for packaging adeno-associated virus (AAV) vectors with a replication-defective adenovirus-AAV (Ad-AAV) hybrid virus. The AAV vector encoding human acid alpha-glucosidase (hGAA) was cloned into an E1, polymerase/preterminal protein-deleted adenovirus, such that it is packaged as ...
Infections with human parvoviruses B19 and recently discovered human bocaviruses (HBoVs) are widespread, while PARV4 infections are transmitted parenterally and prevalent specifically in injecting drug users and hemophiliacs. To investigate the exposure and circulation of parvoviruses related to B19 virus, PARV4, and HBoV in nonhuman primates, plasma ...
Recombinant adeno-associated virus (AAV) vectors are promising tools for gene therapy. In spinal cord injury where extensive damage occurs, vectors with high diffusion and transduction abilities are required. We compared the diffusion capacity and transduction efficiency of AAV2 and AAV5 vectors using a mouse spinal cord injury model. ...
Adeno-associated virus type 2 (AAV) is known to establish latency by preferential integration in human chromosome 19q13.42. The AAV non-structural protein Rep appears to target a site called AAVS1 by simultaneously binding to Rep-binding sites (RBS) present on the AAV genome and within AAVS1. ...
Neutralizing antibodies (NAb) to an adeno-associated virus (AAV) vector due to previous natural infection with wild-type AAV can significantly limit gene transfer. NAb titers to AAV serotype 2 (AAV2) and AAV8 in human subjects (0 to 18 years) were studied. NAb prevalence is moderate at birth, ...
Adeno-associated viruses (AAVs) are small, nonenveloped single-stranded DNA viruses that require helper viruses to facilitate efficient replication. Despite the presence of humoral responses to the wild-type AAV in humans, AAV remains one of the most promising candidates for therapeutic gene transfer to treat many genetic and acquired ...

The choice of adeno-associated virus serotypes for clinical applications is influenced by the animal model and model system used to evaluate various serotypes. In the present study, we sought to compare the biologic properties of rAAV2/1, rAAV2/2, and rAAV2/5 transduction in polarized human airway epithelia using viruses purified by a ...
The impact of paternal care on the postnatal development of inhibitory neuronal subpopulations in prefrontal and limbic brain regions was studied in the rodent Octodon degus. Comparing offspring from biparental families with animals raised by a single mother revealed region-specific deprivation-induced changes in the density of PARV- and CaBP-D28k expressing cells. Some ...
An in vitro system to study the mechanism of site-specific integration of adeno-associated virus (AAV) was developed. This system is based on two substrates, a linear or circular AAV donor and a circular acceptor containing the preintegration locus AAVS1. In the presence of HeLa extract and the His-Tag-purified Rep68 protein, specific ...

Efficiency and specificity of viral vectors are vital issues in gene therapy. Insertion of peptide ligands into the adeno-associated viral (AAV) capsid at receptor binding sites can re-target AAV2-derived vectors to alternative cell types. Also, the use of serotypes AAV8 and -9 is more efficient than AAV2 for gene ...
We have demonstrated the potential of random peptide libraries displayed on adeno-associated virus (AAV)2 to select for AAV2 vectors with improved efficiency for cell type-directed gene transfer. AAV9, however, may have advantages over AAV2 because of a lower prevalence of neutralizing antibodies in humans and more ...
Adeno-associated viruses (AAVs) are leading candidate vectors for human gene therapy. AAV serotypes have broad cellular tropism and use a variety of cellular receptors. AAV serotype 3 binds to heparan sulfate proteoglycan prior to cell entry and is serologically distinct from other serotypes. The capsid features that distinguish ...
Adeno-associated virus (AAV) is a member of the Parvoviridae, belonging to the Dependovirus genus. Currently, several distinct isolates of AAV are in development for use in human gene therapy applications due to their ability to transduce different target cells. The need to manipulate AAV capsids for specific tissue delivery has ...
Abstract Heart disease is the leading cause of morbidity and mortality, and cardiac gene transfer has potential as a novel therapeutic approach. We previously demonstrated safe and efficient gene transfer to the canine heart using a percutaneous transendocardial injection procedure to deliver self-complementary (sc) adeno-associated virus 6 (AAV6) vector. In the present study, ...
Adeno-associated viruses (AAVs) are being developed as gene therapy vectors, and their efficacy could be improved by a detailed understanding of their viral capsid structures. AAV serotype 8 (AAV8) shows a significantly greater liver transduction efficiency than those of other serotypes, which has resulted in efforts to develop this ...
AAV based vectors can achieve stable gene transfer with minimal vector related toxicities. AAV serotype 2 (AAV2) is the first AAV that was vectored for gene transfer applications. However, the restricted tissue tropism of AAV and its low transduction efficiency have limited its further ...
Abstract Viral vectors based on various naturally occurring adeno-associated virus (AAV) serotypes are among the most promising tools in human gene therapy. For the production of recombinant AAV (rAAV) vectors, researchers are focusing predominantly on cross-packaging an artificial AAV genome based on serotype 2 ...
