LL-37 LL-37

A natural human protein involved in fighting infection and healing wounds, studied mostly in lab and animal research. Human evidence mostly just links natural levels of it to different disease states, rather than testing what happens when it's given as a treatment.

Also known as Cathelicidin LL-37, ropocamptide, Cap-18, CAP18, Antibacterial peptide LL-37, antimicrobial peptide LL-37, LL-37 antibacterial peptide
