Scientific Background:β-Defensin 3 (BD-3) is a member of the defensin class of antimicrobial peptides that exert host defense responses against  bacteria, fungi and viruses through microbial membranes. Interferon-gamma stimulates BD-3 expression and is important during adaptive immunity. BD-3 activates monocytes and mast cells, and has antibacterial functions towards Gram-negative and Gram-positive bacteria. Additionally, BD-3 blocks human immunodeficiency virus type 1 (HIV-1) replication through the downregulation of CXCR4, the HIV-1 co-receptor.
Regulatory Status:RUO - Research Use Only
