Hepcidin and Anemia: A Tight Relationship

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 abnormally high, such as inflammation, serum iron falls due to iron trapping within macrophages and liver cells and decreased gut iron absorption. This typically leads to anemia due to … Web23 de jun. de 2011 · Hepcidin has emerged as the central regulatory molecule of systemic iron homeostasis. 1, 2 It is a 25-amino acid peptide hormone that is produced and … rawhide healthy for dogsWebHigh hepcidin levels.
