Figure 1. LAP-mediated phagocytosis by BM macrophages represses leukemic cell expansion in AML.

Figure 1

Apoptotic bodies from AML cells with abundant mitochondria are ingested by BM macrophages via LAP, after which mtDNA stimulates STING to enhance phagocytosis and restrain AML cell growth. Future therapies to enhance LAP-mediated phagocytosis could have therapeutic benefit.
