Defensins description

Human neutrophil defensins (alpha-defensins) belong to the family of cationic trisulfide-containing microbicidal peptides. Azurophilic granules of neutrophils contain Human Neutrophil Peptide (HNP) 1-4 which are highly homologous. The three principal human defensins, HNP 1-3 account for about 99 of the total defensin content of these cells. Besides neutrophils also B cells, T (CD8) cells, NK cells, monocyte/macrophages, epithelial cells produce alpha-defensins. Alpha-defensins exert next to microbicidal activity also chemotactic, immunomodulating, and cytotoxic activities and participate in host defense and inflammation. More recent the antiviral activity of several defensins was discovered. Alpha-defensins-1, -2 and -3 (HNP 1-3) are considered to contribute to the anti-HIV-1 activity of CD8 antiviral factor, findings that open new opportunities to HIV research.
