General description

Chemical structure: peptide
The α-defensin genes, such as DEFA1 (defensin alpha 1) and DEFA3 (defensin α 3) codes for HNP-1, 2 and 3 (human neutrophil peptides). This gene is mapped to human chromosome 8p23.1.

Biochem/physiol Actions

Human neutrophil peptides (HNPs) is involved in endothelial cell dysfunction at the time of early atherosclerotic development. HNP 1−3 can regulate the growth of atherosclerosis. HNP 1−3 levels are usually high in inflammation, including sepsis and acute coronary vascular disorders.
This is an endogenous antibiotic peptide and monocyte chemotactic peptide produced by human neutrophils. Defensins are a family of 3-4 kDa (29-34 amino acids) peptides found in the granules of mammalian phagocytes. The members of this family are variably arginine-rich and share six conserved cysteine residues that participate in intramolecular disulfide bonds.
