WebHepcidin is an iron-regulatory hormone that plays a central role in iron homeostasis by coordinating iron absorption, mobilization, and storage to meet the iron requirements of erythropoiesis and other iron-dependent processes (seeFig. 75.1B ). 25-28 Hepcidin is expressed predominantly in hepatocytes and is secreted into the circulation. WebHepcidin, the iron-regulatory hormone, determines plasma iron concentrations and total body iron content. Hepcidin, secreted by hepatocytes, functions by controlling the activity of the cellular iron exporter ferroportin, which delivers iron to plasma from intestinal iron absorption and from iron stores.
