Beta-Defensin 2 vs Tyrocidine

Beta-Defensin 2 vs Tyrocidine — 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...

Tyrocidine
Antimicrobial Peptide

Tyrocidine A is a cyclic decapeptide component of tyrothricin, one of the first antibiotic mixtures produced commercially. Isolated from Bacillus brevis soil bacteria, tyrocidines are non-ribosomally synthesized peptides that disrupt bacterial membranes through a carpet mechanism...
