Abstract
The shared HLA-bound neoepitopes in pancreatic ductal adenocarcinoma (PDAC) represent a novel class of noncanonical antigens with single amino acid substitutions resulting from translational errors. These peptides, shared across patients with PDAC, showed higher immunogenicity than wild-type counterparts, offering potential candidates for specific immunotherapy development in PDAC.
