Hepcidin synthesis and secretion by the liver is by iron stores, inflammation (hepcidin is an acute phase reactant), hypoxia, and erythropoiesis. In response to large iron stores, production of Bone Morphogenic Protein (BMP) is induced, which binds to receptors on hepatocytes and induces hepcidin … Meer weergeven Hepcidin is a protein that in humans is encoded by the HAMP gene. Hepcidin is a key regulator of the entry of iron into the circulation in mammals. During conditions in which the hepcidin level is … Meer weergeven The peptide was initially reported in January 1998 by Valore,E., Park,C. and Ganz,T. in the SWISS-PROT database as entry P81172 and named hepcidin after it was observed that it was produced in the liver ("hep-") and appeared to have bactericidal … Meer weergeven • Camaschella C (December 2005).
