Hepcidin and iron disorders: new biology and clinical approaches

Hepcidin is a regulator of iron metabolism. It inhibits iron transport by binding to the iron export channel ferroportin which is located in the basolateral plasma membrane of gut enterocytes and the plasma membrane of reticuloendothelial cells (macrophages), ultimately resulting in ferroportin breakdown in lysosomes. It has been shown that hepcidin is able to bind to the central cavity of ferropor… WebTherefore，hepcidin is a new target for pharmacological intervention in these diseases.
