ClinConnect Summary

Hepcidin is the major hormone regulating Iron Metabolism. Synthesized primarily by hepatocytes, it interacts with the cellular iron exporter ferroportin, causing its internalization and preventing the release of iron from enterocytes and macrophages.

In a normal organism decrease iron stock causes a decrease in hepcidin synthesis thus promoting intestinal absorption of iron.

Since valid methods for the determination of hepcidin serum rate are available, this dosage is increasingly used to diagnosis iron metabolism pathologies, in particular iron overload. The interpretation of hepcidin do...
