Systemic iron homeostasis.

The iron hormone hepcidin and its receptor and cellular iron exporter ferroportin control the major fluxes of iron into blood plasma: intestinal iron absorption, the delivery of recycled iron from macrophages, and the release of stored iron from hepatocytes. Because iron losses are comparatively very small, iron absorption and its regulation by hepcidin and ferroportin determine total body iron content. Hepcidin is in turn feedback-regulated by plasma iron concentration and iron stores, and…

Systemic iron homeostasis and erythropoiesis
- Medicine, BiologyIUBMB life

This review focuses on systemic iron homeostasis in the context of erythropoiesis, a highly iron‐demanding process, and discusses the function and regulation of hepcidin by various stimuli, and highlights hePCidin‐dependent and ‐independent mechanisms that link iron utilization with maturation of ERYthroid progenitor cells.

The present review summarizes the current understanding of the molecular mechanisms and signaling pathways contributing to hepcidin regulation by these factors and highlights the issues that still need clarification.
Modelling Systemic Iron Regulation during Dietary Iron Overload and Acute Inflammation: Role of Hepcidin-Independent Mechanisms
- BiologyPLoS Comput. Biol.
- 2017
A mathematical model of systemic iron regulation that incorporates the dynamics of organ iron pools as well as regulation by the hepcidin/ferroportin system is built and demonstrates that inflammation mainly reduces the amount of iron in the blood stream by reducing intracellular ferro portin transcription, and not by hePCidin-dependent ferroportIn protein destabilization.

ER Stress Controls Iron Metabolism Through Induction of Hepcidin

It is found that endoplasmic reticulum (ER) stress also induces hepcidin expression and causes hypoferremia and spleen iron sequestration in mice, suggesting a direct link between the intracellular stress response, innate immunity, and iron metabolism.

Hepcidin was found to be suppressed in patients with thalassemia syndromes and congenital dyserythropoietic anemia type 1 and was undetectable in patientswith juvenile hemochromatosis with HAMP mutations, and urine hepcidin levels were significantly elevated in 2 patients with hemochROMatosis type 4.

Hepcidin can trigger ferroportin degradation in hepatocytes, which must be taken into account when considering hepcidin therapeutics, which is shown to support the centrolobular iron deposition observed in mice.

Small interfering RNAs (siRNAs) were developed against HAMP, the hepcidin gene, as well as other targets involved in iron metabolism, both as a means to identify a therapeutic for the treatment of anemia and as a Means to further characterize the hePCidin signaling pathway.

It is shown that BMP-2 administration increases hepcidin expression and decreases serum iron levels in vivo and that soluble hemojuvelin (HJV.Fc) selectively inhibits BMP induction of hepcIDin expression in vitro and this data support a role for modulators of the BMP signaling pathway in treating diseases of iron overload and anemia of chronic disease.
