Overview
LL-37 is the only human cathelicidin antimicrobial peptide, a 37-amino acid peptide cleaved from the C-terminus of the precursor protein hCAP18. It is expressed by neutrophils, macrophages, and epithelial cells as a first-line innate immune defense molecule with broad-spectrum antimicrobial and immunomodulatory activity.
Mechanism of Action
LL-37 disrupts microbial membranes through electrostatic interactions with negatively charged lipid bilayers, creating pores that kill bacteria, fungi, and enveloped viruses. Beyond direct antimicrobial action, it modulates immune cell recruitment (chemotaxis), promotes wound healing and angiogenesis, neutralizes endotoxin (LPS), and influences adaptive immune responses through dendritic cell modulation.
Research Context
LL-37 research spans infectious disease, wound healing, autoimmune conditions, and cancer immunology. Its dual role as both antimicrobial agent and immune modulator makes it unique among research peptides.
Key Research Areas
Considerations for Researchers
Larger peptide (37 amino acids) with amphipathic structure. Store lyophilized at -20C. The antimicrobial nature means contamination testing is especially important. Reconstitute with endotoxin-free water for immunology research.
