To evaluate if any CRC phosphopeptides are commonly targeted by CRC patient TILs, we selected a subset of phosphopeptides that were predicted to bind to commonly expressed HLA-I alleles - HLA-A*02, HLA-C*06 and HLA-C*07 - and have also been identified in other malignancies (19, Penny et al., unpublished). This evidence concerns the gene HLA-C and colorectal carcinoma.
