Antimicrobial Peptide

Also called AMP · host defense peptide · cathelicidin · defensin

Antimicrobial peptides (AMPs) are a class of host-defense peptides produced by innate immune cells and epithelial tissues. They typically carry a net positive charge and fold into amphipathic structures that disrupt bacterial and fungal membranes. LL-37 (cathelicidin) is the only AMP of its family found in humans.
