Web17 dec. 2004 · The hepcidin-ferroportin interaction may be central to the pathophysiology of hereditary hemochromatosis and the anemia of inflammation. Most types of hemochromatosis are characterized by hepcidin deficiency ( 18) or, less frequently, by autosomal dominant mutations of ferroportin ( 18 ). WebHepcidin, a hepatic-secreted peptide hormone, binds to Fpn and promotes internalization and degradation of Fpn, resulting in the decreased export of non-heme iron ( Nemeth et al., 2004 ). In addition to the Hepcidin-Fpn signaling pathway, the miR-124/Fpn signaling pathway has also been confirmed to affect the occurrence of ferroptosis.
