Although an adequate supply of dietary iron is essential, you might be surprised to learn that the absorption of iron from the food we eat is relatively inefficient . (mysportscience.com)
Not only does this tell us that iron absorption is inefficient at the level of the gut, but also that vegetarian athletes must make extra effort to ensure adequate sources of non-heme iron are consumed to make up for the lower relative absorption rate. (mysportscience.com)
Notwithstanding, the other foods we consume with our high iron containing meals are also important for us to consider, since we know that the co-ingestion of calcium, tannins (in tea and coffee), and phytates, for instance, can further inhibit the absorption of iron, whereas the addition of Vitamin C (ascorbic acid) to our meal can actually enhance our ability to absorb iron from our food. (mysportscience.com)
Generally, increases in hepcidin levels results in a decrease in iron absorption, whereas decreases in hepcidin result in an increase to iron absorption. (mysportscience.com)
It turns out that, although important, too much iron is actually toxic to our body, and so, hepcidin acts to regulate the absorption of iron to ensure we don't have too much in our system (i.e., more isn't necessarily better when it comes to iron). (mysportscience.com)

Recent findings have shown that iron is a powerful regulator of immune responses, which is of broad importance because iron deficiency is highly prevalent worldwide. (ox.ac.uk)
We identified iron-interacting proteins in CD4+ and CD8+ T-cell proteomes that were differentially expressed during activation, suggesting that pathways enriched with such proteins, including histone demethylation, may be impaired by iron deficiency. (ox.ac.uk)

Over the last decade the Haase group has focused on investigating the role of HIF in the regulation of erythropoiesis and iron metabolism. (haaselab.org)
Specifically, we have identified HIF-2 as the key regulator of renal EPO synthesis and have established that HIF coordinates erythropoiesis with iron metabolism by directly regulating iron uptake and release. (haaselab.org)
More recently, the Haase lab investigated the role of HIF in the regulation of hepcidin and was able to show that the hypoxic suppression of hepcidin occurs indirectly through HIF-2-mediated stimulation of erythropoiesis. (haaselab.org)
Iron accumulates in cells that lack plasma membrane ferroportin, which leads to lower amounts of circulating iron available for erythropoiesis. (biomedcentral.com)
The differential diagnosis of iron accumulation in macrophages also includes the anemia of inﬂammation, in which anemia is associated with inappropriate retention of iron in macrophages and hepatocytes despite iron-restricted erythropoiesis. (intrinsiclifesciences.com)

It inhibits iron transport by binding to the iron export channel ferroportin which is located in the basolateral plasma membrane of gut enterocytes and the plasma membrane of reticuloendothelial cells (macrophages), ultimately resulting in ferroportin breakdown in lysosomes. (wikipedia.org)
It has been shown that hepcidin is able to bind to the central cavity of ferroportin, thus occluding iron export from the cell. (wikipedia.org)
This suggests that hepcidin is able to regulate iron export independently of ferroportin endocytosis and ubiquitination, and is thus quickly inducible and reversible. (wikipedia.org)
