Antibacterial Protein LL-37

Antibacterial Protein LL-37 is a naturally occurring antimicrobial peptide (AMP) in the human immune system. It is the only known human cathelicidin-derived peptide and plays a central role in innate immunity, acting as a rapid first-line defense against bacteria, viruses, and fungi. Unlike many synthetic “research peptides,” Antibacterial Protein LL-37 is endogenous (produced by the body) and is part of normal immune biology.
