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.
- Researched for
- Antimicrobial defense; wound healing; immune modulation; melanoma research; inflammatory skin disease
- Half-life
- Not established in humans
- Familiarity
- Advanced
- Research evidence
- Human trials - early or small
- Regulatory status
- Preclinical
- Key risk
- Local dermatologic toxicity, including skin reactions, has been reported when it is injected into lesions.
