CD8A and neoplasm: Indeed, the advanced OC tumor microenvironment (TME) is characterized by a lack tumor infiltrating lymphocytes (TILs) and failed T‐cell priming due to a combination of poor antigen presentation and an intrinsic insensitivity to T‐cell killing.10,11 More specifically, tumor growth is associated with a scarcity (if not total absence) of CD8+ T cells within the TME,12 or the inability of dendritic cells (DCs) to effectively present antigen and stimulate a cytotoxic response.13
