Beta-Defensin-1 vs Beta-Defensin 2

Beta-Defensin-1 vs Beta-Defensin 2 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Beta-Defensin-1
Antimicrobial Peptide

Human beta-defensin-1 (HBD-1) is a constitutively expressed antimicrobial peptide produced by epithelial cells of the skin, respiratory tract, and genitourinary system. Unlike inducible defensins, HBD-1 is present at steady-state levels as a component of basal innate immune defen...

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...
