As shown in Figure S3, the percentage of CD8A-positive T lymphocytes expressing HAVCR2 and/or PDCD1 was lower in cases of intraductal papillary mucinous neoplasms (IPMN) and serous cystadenoma (SC) compared to the percentage observed in PDAC. This evidence concerns the gene HAVCR2 and pancreatic intraductal papillary-mucinous neoplasm.
