Beta-Defensin 2 vs Pexiganan

Beta-Defensin 2 vs Pexiganan — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Beta-Defensin 2
Antimicrobial Peptide

Human beta-defensin 2 (HBD-2) is an inducible antimicrobial peptide expressed by skin keratinocytes, respiratory epithelium, and gut epithelium in response to microbial infection and pro-inflammatory cytokines. Unlike the constitutively expressed HBD-1, HBD-2 expression is strong...
