4. Figure 3
Iron metabolism by peritoneal macrophages. Macrophages acquire most of their iron by phagocytosing red blood cells or endocytosing the hemoglobin–haptoglobin complex. Proteolytic digestion of hemoglobin liberates heme, which is catabolized by heme oxygenase (HO) to produce reactive iron. The free iron released is then incorporated into macrophage ferritin or returned to the iron transporter transferrin in peritoneal fluid. Hepcidin may regulate iron metabolism by macrophages via inhibiting iron efflux through ferroportin (FPN).
