Beta-Defensin 2 vs Human Neutrophil Peptide 1

Beta-Defensin 2 vs Human Neutrophil Peptide 1 — 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...

Human Neutrophil Peptide 1
Antimicrobial Peptide

Human Neutrophil Peptide 1 (HNP-1) is the most abundant alpha-defensin in human neutrophil granules, where it constitutes up to 30% of total protein content. Alpha-defensins HNP-1, -2, -3, and -4 are the human versions of the ancestral defensin family....
