We also tested T cells directed to three other diabetes-relevant epitopes, including the InsB:11-25 peptide (Wan et al., 2020), the insulin–chromogranin A fused peptide (recognized by the BDC2.5 T cell; Delong et al., 2016), and the 206–214 peptide from the islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP:206-214) presented by the MHC-I molecule Kd (recognized by the 8.3 T cell; Lieberman et al., 2003). This evidence concerns the gene INS and diabetes mellitus.
