WebHeme is primarily obtained from meat sources and is taken up by enterocytes by heme carrier protein 1 (HCP1) (upper), whereas inorganic iron (Fe3+) is reduced to Fe2+by duodenal cytochrome b1(DCytb1) and is subsequently transported into the enterocyte by divalent metal transporter 1 (DMT1) (lower). WebThese iron recycling macrophages are a major storage site for iron in addition to liver hepatocytes. All other cells in the body contain smaller amounts of iron for essential cellular processes as noted above. The circulating pool of iron is comparatively small (2–4 mg) and must be turned over every few hours to meet the daily requirement of ...
WebJul 1, 2015 · To maintain iron homeostasis, the organism controls the dietary iron absorption by enterocytes, its recycling by macrophages and storage in hepatocytes. These processes are mainly controlled by hepcidin, a liver-derived hormone which synthesis is regulated by iron levels, inflammation, infection, anemia and erythropoiesis. WebAug 2, 2024 · Given the critical roles of hepatocytes in mediating iron storage and supply, we assessed hepatic iron balance in NAFLD and NASH. We found that total iron levels in human NAFLD/NASH hepatocytes were significantly lower than in healthy hepatocytes (Figure 1A).In addition, the abundance of both ferritin H (FTH) and L (FTL) subunits, which …
