About
LL-37 is the active fragment of human cathelicidin, the only cathelicidin our species makes. It's a 37-amino-acid antimicrobial peptide produced by neutrophils and epithelial cells as part of the innate immune response, and it punches holes in bacterial membranes the way detergents punch holes in oily films.

- Broad-spectrum antimicrobial activity in vitro. Bacteria, fungi, some viruses, including biofilm-forming organisms
- Wound healing benefit in early topical trials for chronic ulcers
- Immune modulation, both anti-inflammatory and pro-inflammatory depending on context. Interesting, but not necessarily what you want unsupervised
- Useful research interest as a template for next-generation antimicrobials, where antibiotic resistance is squeezing the conventional pipeline
