Beta-Defensin-1 vs Tyrocidine

Beta-Defensin-1 vs Tyrocidine — 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...

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...
