Iron storage hepatocytes
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 … 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).
