Red Carpet Iron Metabolism
Iron is both necessary to the body and potentially toxic.
Red carpet iron metabolism. High hepcidin levels block intestinal iron absorption and macrophage iron recycling causing iron restricted erythropoiesis and anemia. Controlling iron levels in the body is a critically important part of many aspects of human health and disease. 2017 muckenthaler et al. Iron metabolism in erythroid cells red blood cells rbcs are formed from lineage committed progenitors during erythropoiesis a highly regulated process.

Human iron metabolism is the set of chemical reactions that maintain human homeostasis of iron at the systemic and cellular level. Cellular iron metabolism is post transcriptionally controlled by iron regulatory proteins irp1 and irp2 while systemic iron balance is regulated by the iron hormone hepcidin. Low hepcidin levels favor bone marrow iron supply for hemoglobin synthesis and red blood cells production.
