CD274 and neoplasm: Taken together, the above findings suggest that (1) CNH-PG-mPT has a low level of anti-TNBC efficacy; (2) CNH-PG-mPT increases the presence of M1-like macrophages and PD-L1 expression in the tumor tissue; (3) these effects (but for PD-L1 induction) of CNH-PG-mPT can be significantly enhanced by BMS-1; (4) both the tumor cells and the infiltrating macrophages express PD-L1.
