A20 is a ubiquitin modifying enzyme that restricts NF-?B signals and protects cells against tumor necrosis factor (TNF) induced programmed cell death. Given recent data linking A20 (TNFAIP3) with human B cell lymphomas and systemic lupus erythematosus (SLE), we have generated ...

TNF receptor 1 can activate signaling pathways leading to the activation of NF-kappaB. A20, an NF-kappaB-inducible protein, negatively regulates these signaling pathways and acts as an anti-inflammatory mediator. Therefore, A20 is viewed as a potential therapeutic target for inflammatory disease. In this study, we ...

We have recently screened human adenoviruses (Ads) for oncolytic activity against a variety of mouse and hamster cell lines and have found a number that are susceptible to a variety of Ad serotypes. A20 lymphoma is derived from BALB/c mice and is susceptible to infection and killing by a variety of human Ads. ...
A20 or tumor necrosis factor�induced protein 3 is a negative regulator of nuclear factor ?B signaling. A20 has been shown previously to attenuate cardiac hypertrophy in vitro and postmyocardial infarction remodeling in vivo. In the present study, we tested the hypothesis that overexpression of A20 in the murine ...
The Ig Id of a B cell lymphoma is a tumor-specific Ag, although as a self-Ag it is likely to be a weak immunogen. Provision of a foreign gene may enhance the immunogenicity of the idiotype. Viral vectors allow highly efficient transfer of genetic material and are themselves innately immunogenic. We have investigated the ability of recombinant adenoviral vectors, encoding the idiotypic gene with or ...
Several negative regulatory mechanisms control Toll-like receptor (TLR)-mediated inflammatory responses and restore immune system balance, including the zinc-finger protein A20, a negative regulator of TLR signalling that inhibits nuclear factor kappa B (NF-kappaB) activity. In the present study, we investigated TLR-5-mediated ...

A20 (TNFAIP3) is a protein that is involved in the negative feedback regulation of NF-?B signaling in response to specific proinflammatory stimuli in different cell types and has been suggested as a susceptibility gene for rheumatoid arthritis. To define the contribution of A20 to rheumatoid arthritis pathology, we generated myeloid-specific ...
Cytokine gene-modified tumor cells have increased immunogenicity and retain the antigenic repertoire of a particular neoplasia. However, practical concerns have led to an increased interest in allogeneic gene-transduced bystander cells as a broader source of cytokines for autologous tumor cell-based vaccines. Here, we show that allogeneic B78H1 major histocompatibility complex (MHC) class ...
