When excluding CRC, STAD and UCEC, immune dN/dS and CD8 T cells correlation increased significance for both immunopeptidomes, supporting our hypothesis of immune escape masking immune selection (HLA-A0201: r = −0.78, P = 0.0017, Fig. 2f; proto-HLA: r = −0.61, P = 0.028, Fig. 2g). This evidence concerns the gene CD8A and colorectal carcinoma.
