About LL-37

What it is
LL-37 is the only human cathelicidin-derived antimicrobial peptide, a 37 amino acid molecule made by epithelial cells and various white blood cells. It disrupts the membranes of bacteria and other microbes and also shapes the innate immune response, drawing in immune cells and aiding wound repair. It has been studied mainly for infection defense, chronic wound healing, and, in small trials, as a local agent injected into melanoma.
How it works
It punctures microbial membranes and also modulates the innate immune response, recruiting immune cells and supporting tissue repair.
