defensin hnp-3

Defensin HNP-3 is a peptide secreted by human polymorphonuclear leukocytes (PMNs) that has antimicrobial properties. It induces lysis of mammalian cells when used at a concentration of 25 μg/mL. It also inhibits growth of E. faecalis (ED50 = 100 nM) and clinical isolates of P. aeruginosa (MIC90 = 4 μM). HNP-3 binds to recombinant HIV-1 envelope glycoprotein (gp120) and human CD4 (Kds = 52.8 and 34.9 nM, respectively). It also binds to recombinant, immobilized human surfactant protein D (SP-D; Kd = 55.7 nM) and inhibits focus formation in Madin-Darby canine kidney (MDCK) cells infected with influenza A virus (IAV).

Defensin HNP-3 human 是一种具有抑制金黄色葡萄球菌、铜绿假单胞菌和大肠杆菌活性的细胞毒性抗生素肽。该肽原先以94个氨基酸的preproHNP(1-94)形式合成，随后水解为proHNP(20-94)，最终通过去除阴离子前体转化为成熟形式的HNP(65-94)。

Defensin HNP 4，一种由11个氨基酸组成的HNP-41-11的片段，对多药耐药及非耐药菌株均显示出抑制效果。

β-Defensin-3 is a peptide with antimicrobial properties that protects the skin and mucosal membranes of the respiratory, genitourinary, and gastrointestinal tracts. It inhibits the growth of the periodontopathogenic and cariogenic bacteria F. nucleatum, S. mutans, S. sobrinus, S. salivarius, and L. casei (MICs = 12.5-100 mg/l). It also inhibits the growth of S. aureus, S. pyogenes, P. aeruginosa, E. coli, and C. albicans. β-Defensin-3 stimulates gene expression and production of IL-6, IL-10, CXCL10, CCL2, MIP-3α, and RANTES by keratinocytes when used at a concentration of 30 μg/ml. It also stimulates calcium mobilization, migration, and proliferation of keratinocytes when used at concentrations of 30, 5, and 20 μg/ml, respectively. β-Defensin-3 induces IL-31 production by human peripheral blood-derived mast cells in vitro when used at a concentration of 10 μg/ml and by rat mast cells in vivo following a 500 ng intradermal dose.
