miR-23a-3p, induced by tumor-derived TGF-β, has been reported to suppress the cytotoxicity of tumor-infiltrating CD8+ cytotoxic T lymphocytes through the direct repression of BLIMP-1 [33], and miR-125b-5p has been found to suppress γδ T-cell cytotoxicity against tumor cells [34]. Here, PRDM1 is linked to neoplasm.
