Retroviral-Mediated Stem Cell Gene Nonobese Diabetic Mice: Generation by Decarboxylase 65-Specific TCR Retrogenic Diabetes Incidence Is Unaltered in Glutamate

CD4+ T Cells from Glutamic Acid Decarboxylase (GAD)65-specific T Cell Receptor Transgenic Mice Are Not Diabetogenic and Can Delay Diabetes Transfer

Glutamic acid decarboxylase (GAD)65 is an early and important antigen in both human diabetes mellitus and the nonobese diabetic (NOD) mouse. However, the exact role of GAD65-specific T cells in diabetes pathogenesis is unclear. T cell responses to GAD65 occur early in diabetes pathogenesis, yet only one GAD65-specific T cell clone of many identified can transfer diabetes. We have generated tran...

Prevention of type I diabetes transfer by glutamic acid decarboxylase 65 peptide 206-220-specific T cells.

Glutamic acid decarboxylase (GAD) 65 is one of the major pancreatic antigens targeted by self-reactive T cells in type I diabetes mellitus. T cells specific for GAD65 are among the first to enter inflamed islets and may be important for the initiation of autoimmune diabetes. However, we previously reported that nonobese diabetic (NOD) mice transgenic for a T cell antigen receptor (TCR) specific...

On the pathogenicity of autoantigen-specific T-cell receptors.

OBJECTIVE Type 1 diabetes is mediated by T-cell entry into pancreatic islets and destruction of insulin-producing beta-cells. The relative contribution of T-cells specific for different autoantigens is largely unknown because relatively few have been assessed in vivo. RESEARCH DESIGN AND METHODS We generated mice possessing a monoclonal population of T-cells expressing 1 of 17 T-cell receptor...
