BDC2.5 Mimotope 1040-63 is a biological active peptide. (The TCR transgenic model (BDC2.5) mimitope was used in type 1 diabetes (T1D) study. T1D is an autoimmune disease in which T cells mediate damage to pancreatic islet b cells. T1D is caused by autoreactive T cell destruction of insulin-producing cells. BDC2.5 mimotope was utilized to support the study on antigen presentation of antigenic peptides to islet autoantigen-specific T cells.)
