Additional antigens include MHC, glial fibrillary acidic protein (GFAP), serum albumin, islet amyloid polypeptide precursor (IAPP), insulin-like growth factor (IGF), TCR and chromogranin A. In this context, the serum albumin references relate to tolerance to cow milk in diabetes patients and induction of tolerance in general; similarly, several references describe the binding and immunogenicity or tolerogenicity of MHC and/or TCR derived peptides in the context of autoimmune diabetes (see below for tolerogenic peptide-based query). Here, GFAP is linked to diabetes mellitus.
