Overview
What is LL-37?
LL-37 is the active fragment of human cathelicidin antimicrobial protein, a component of innate immunity found in neutrophils and epithelial surfaces.
Mechanism
How it works
Research describes direct membrane activity against a broad range of microbes alongside immunomodulatory signaling and involvement in wound repair — a dual role that distinguishes it from conventional antimicrobials.
