Human iron homeostasis is regulated at two different levels. Systemic iron levels are balanced by the controlled absorption of dietary iron by enterocytes, the cells that line the interior of the intestines, and the uncontrolled loss of iron from epithelial sloughing, sweat, injuries and blood loss. In addition, systemic iron is continuously recycled. Cellular iron levels are controlled differently by di… WebOct 15, 2015 · iron uptake from the intestinal lumen is carried out by the iron/H + cotransporter DMT1, which is present in the apical membrane of absorptive enterocytes. Four isoforms of DMT1 are generated by alternative splicing of the 5′-end exons (exons 1A or 1B) and of the 3′-end exons [exons 16 (or +IRE) or 17 (or −IRE)] ().Enterocytes and Caco … foam faucet cover walmartWebIron is biologically essential, but also potentially toxic; as such it is tightly controlled at cell and systemic levels to prevent both deficiency and overload.
