Cell death is a common event in solid tumors during malignant process; corpse clearance, which is referred to as “efferocytosis”, has important effects on immunosuppression.[28] Defects in efferocytosis contributes to anti‐tumor immunity via increasing population of M1‐like TAMs and cytotoxic T cells in TME.[29, 30] Since our data show a relatively high population of M1‐like TAMs in tumor tissues from mKO mice this may indicate that NAMPT deficiency leads to defects in efferocytosis compared to cells with high expression of NAMPT. The gene discussed is NAMPT; the disease is neoplasm.
