Beta-Defensin 2 vs Lactoferricin

Beta-Defensin 2 vs Lactoferricin — 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...

Lactoferricin
Antimicrobial Peptide

Lactoferricin B (LfcinB) is a 25-residue antimicrobial peptide released from the N-terminal region of bovine lactoferrin by pepsin digestion in the stomach. The core hexapeptide RRWQWR contains the minimal active unit....
