CD8A and type 1 diabetes mellitus: TCR α-chains that contained the SGGSNYKLTF motif were detected in all donors and their abundance in naïve or memory CD8+ T cells was not significantly increased in AAb+ (median, naive 0.77% and memory 0.89%) or recent onset type 1 diabetes patients (median, 1.06% and 0.63%) as compared to control children (median, 1.07% and 0.73%), arguing against a general association of TCRs containing this motif with disease.
