CD8A and neoplasm: Here, double staining of PD‐L1 and CD8 showed a pronounced infiltration of PD‐L1 high BCC tumors with CD8+ T cells together with focal PD‐L1 expression on tumor cells in close proximity to CD8+ T lymphocytes, suggesting inhibition of cytotoxic T cells by PD‐L1 expressing BCC cells via immune checkpoint signaling (Fig. 2G,H).
