Hepcidin, a key iron-regulatory hormone primarily synthesized in the liver, plays a central role in maintaining systemic iron homeostasis. Discovered in 2000. this small, cysteine-rich peptide regulates dietary iron absorption and macrophage iron recycling by binding to the iron exporter ferroportin, triggering its internalization and degradation. Dysregulation of hepcidin is implicated in various iron-related disorders, including hereditary hemochromatosis (low hepcidin) and anemia of chronic disease (elevated hepcidin).
Recombinant hepcidin (rhHepcidin) is produced via genetic engineering, typically using bacterial (E. coli) or mammalian expression systems. Its production addresses the challenges of natural hepcidin's short half-life and low abundance. RhHepcidin retains the bioactive 25-amino-acid form, including eight conserved cysteines forming four disulfide bonds critical for function. Structural authenticity is ensured through advanced purification and folding techniques.
Therapeutically, rhHepcidin shows promise for treating iron overload disorders by mimicking endogenous hepcidin activity. Conversely, hepcidin antagonists are explored for anemia management in chronic inflammation. Research also investigates its role in infections, as pathogens require iron for proliferation, and hepcidin-mediated iron sequestration constitutes a host defense mechanism. Challenges include optimizing pharmacokinetics and minimizing off-target effects. Recent advances in peptide engineering, such as PEGylation or fusion proteins, aim to enhance stability and efficacy.
As a research tool, rhHepcidin enables mechanistic studies of iron metabolism and drug screening. Its development underscores the intersection of molecular biology and clinical medicine, offering potential therapies for globally prevalent iron disorders.
