Beta-Defensin-1 vs Teixobactin

Beta-Defensin-1 vs Teixobactin — 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...

Teixobactin
Antimicrobial Peptide

Teixobactin was reported in Nature in 2015 as the first new antibiotic class discovered in 30 years, isolated from uncultured soil bacteria Eleftheria terrae using the iChip (isolation chip) technology that allows cultivation of previously unculturable organisms. Teixobactin bind...
