Hepcidin antimicrobial peptide

Hepcidin, hepcidin-25
The product encoded by this gene is involved in the maintenance of iron homeostasis, and it is necessary for the regulation of iron storage in macrophages, and for intestinal iron absorption. The preproprotein is post-translationally cleaved into mature peptides of 20, 22 and 25 amino acids, and these active peptides are rich in cysteines, which form intramolecular bonds that stabilize their beta-sheet structures. These peptides exhibit antimicrobial activity. Mutations in this gene cause hemochromatosis type 2B, also known as juvenile hemochromatosis, a disease caused by severe iron overload that results in cardiomyopathy, cirrhosis, and endocrine failure.

Hepcidin and Iron Metabolism in Pregnancy: Correlation with Smoking and Birth Weight and Length.
New
Ołtarzewski et al., Warsaw, Poland. In Biol Trace Elem Res, 20 Feb 2016
UNASSIGNED: To estimate the effect of tobacco smoking on iron homeostasis and the possible association between hepcidin and the neonatal birth weight and length, concentrations of serum hepcidin and selected iron markers were measured in 81 healthy pregnant women (41 smokers and 40 nonsmokers).

New
Meynard et al., Milano, Italy. In Blood, 11 Feb 2016
UNASSIGNED: Hepcidin, the main regulator of iron homeostasis, is repressed when erythropoiesis is acutely stimulated by erythropoietin (EPO) to favor iron supply to maturing erythroblasts.
Tipping the balance: Haemoglobinopathies and the risk of diabetes.
New
Patel et al., Nottingham, United Kingdom. In World J Diabetes, 10 Feb 2016

New
Miele et al., Napoli, Italy. In J Crohns Colitis, 04 Feb 2016
BACKGROUND AND AIMS: We sought to correlate hepcidin levels in Inflammatory Bowel Disease (IBD) children with disease activity, inflammatory markers and iron load test (ILT) and to compare IBD patients with celiac and healthy patients.
