CCNI and neoplasm: Although this study only investigated the CCNI-ED peptides in depth, our finding that 3 out of 15 TILs positively reacted to CCNI-ED 10, and 1 out of 15 TILs reacted to CCNI-ED 9, suggests the possibility that edited peptides serve as a source of antigens that activate tumour-specific T cells which infiltrate into tumour site to mediate antitumor immunity.
