Hepcidin, immunity and global health
If you have a question about this talk, please contact Sue Griffin.
Host: Adrian Kelly (email@example.com)
Iron lies at the center of a battle for nutritional resource between higher organisms and their microbial pathogens. The iron status of the human host affects the pathogenicity of numerous infections including malaria, HIV -1, and tuberculosis.
Hepcidin, an antimicrobial-like peptide hormone, has emerged as the master regulator of iron metabolism. Hepcidin controls the absorption of dietary iron and the distribution of iron among cell types in the body, and its synthesis is regulated by both iron and innate immunity.
We describe how hepcidin integrates signals from diverse physiological inputs, forming a key molecular link between iron trafficking and response to infection. Manipulation of hepcidin constitutes a new method for controlling immunity.
