Abstract:Pancreatic ductal adenocarcinoma (PDAC) is the classic cold tumor, with few tumor-infiltrating activated CD8+ T cells, a major barrier to immunotherapy. Strategies to convert cold PDACs to hot can enable more effective immunotherapies. To identify targets that can convert cold PDACs to hot, we compared a large cohort of rare long-term PDAC survivors with hot tumors to short-term survivors with cold tumors. Surprisingly, hot PDACs were enriched not only in activated CD8+ T cells, but also in group-2 innate lymp… Show more
