Peptide specific amelioration of T cell mediated pathogenesis in murine type 1 diabetes

NOD mice spontaneously develop insulitis and type 1 diabetes (T1D) mellitus similar to humans. Insulitis without overt disease occurs in the BDC2.5 TCR-transgenic NOD mice that express the rearranged TCR alpha- and beta-chain genes of a diabetogenic T cell clone reactive to an unknown beta cell auto...

520 |a NOD mice spontaneously develop insulitis and type 1 diabetes (T1D) mellitus similar to humans. Insulitis without overt disease occurs in the BDC2.5 TCR-transgenic NOD mice that express the rearranged TCR alpha- and beta-chain genes of a diabetogenic T cell clone reactive to an unknown beta cell autoantigen. A previous study identified an extensive panel of peptides that are highly active in stimulating T cells from transgenic BDC2.5 mice in culture. However, none of these peptides cause active disease in NOD and BDC2.5 animals or in NOD recipients of adoptively transferred BDC2.5 T cells following direct immunization in vivo. We show that direct immunization of transgenic BDC2.5 mice causes many BDC2.5 T cells to become activated and apoptotic. Strikingly, soluble peptides administered to recipients of activated, highly pathogenic BDC2.5 T cells results in protection from disease. These results suggest that high affinity peptide analogues of autoimmune epitopes might be useful as therapeutic modulators in active autoimmune disease
