CD36 (also known as platelet glycoprotein IV, OKM5-antigen, or platelet glycoprotein IIIb) acts as a receptor for thrombospondin (TSP), collagen, falciparum malaria parasitized erythrocytes, and sickle erythrocytes. It also functions as a scavenger receptor, mediating macrophage uptake of oxidized low-density lipoprotein (LDL), and apoptotic polymorphonuclear leukocytes (PMN). CD36 plays a role in platelet aggregation, macrophage foam cell development, inflammation, and the tissue ischemia observed in sickle cell disease and cerebral malaria.
