β-defensin-1

β-Defensin-1 is a peptide with antimicrobial properties that protects the skin and mucosal membranes of the respiratory, genitourinary, and gastrointestinal tracts.1It inhibits the growth ofB. adolescentis,L. acidophilus,B. breve,B. vulgatus,L. fermentum,B. longum, andS. thermophilusin an antimicrobial radial diffusion assay.2β-Defensin-1 also inhibits the growth of periodontopathogenic and cariogenic bacteria, includingP. gingivalisandS. salivarius, and of susceptibleM. tuberculosisH37Rv but not of resistantM. tuberculosisRM22 when used at a concentration of 128 μg/ml.3,4It blocks human and mouse Kv1.3 voltage-gated potassium channels (IC50s = 11.8 and 13.2 μM, respectively).5Overexpression of β-defensin-1 in the human oral squamous cell carcinoma (OSCC) cell lines HSC-3, UM-1, and SCC-9 increases migration and invasion but not proliferation.6 1.Lehrer, R.I.Primate defensinsNat.

β-Defensin-2 is a peptide with antimicrobial properties that protects the skin and mucosal membranes of the respiratory, genitourinary, and gastrointestinal tracts.1It inhibits the growth of periodontopathogenic and cariogenic bacteria, includingP. gingivalisandS. salivarius.2β-Defensin-2 (30 μg/ml) stimulates gene expression and production of IL-6, IL-10, CXCL10, CCL2, MIP-3α, and RANTES by keratinocytes.3It also stimulates calcium mobilization, migration, and proliferation of keratinocytes when used at concentrations of 30, 10, and 40 μg/ml, respectively. β-Defensin-2 induces IL-31 production by human peripheral blood-derived mast cellsin vitrowhen used at a concentration of 10 μg/ml and by rat mast cellsin vivofollowing a 500 ng intradermal dose.4Expression of β-defensin-2 is increased in psoriatic skin and chronic wounds.5,6 1.Lehrer, R.I.Primate defensinsNat.
