LL37

LL-37 — Research Overview

LL-37 is a naturally occurring antimicrobial peptide (AMP) derived from the human cathelicidin protein (CAMP). It is a key component of the innate immune system and has been widely studied for its role in host defense, immune modulation, and tissue-level responses.

Research interest in LL-37 spans immunology, microbiology, inflammation pathways, and cellular repair mechanisms. Due to its broad activity profile, LL-37 remains an active focus in laboratory and preclinical research settings.

What Is LL-37?

LL-37 is a 37–amino acid cationic peptide produced by various cell types, including epithelial cells, neutrophils, and macrophages. It is released in response to immune signaling and plays a role in first-line defense against pathogens.

In research environments, synthetic LL-37 is used to study peptide-mediated immune responses, microbial interactions, and inflammatory signaling pathways.
