What is LL-37?
LL-37 is a 37-amino acid cationic antimicrobial peptide — the only known human cathelicidin, derived from the C-terminus of the cathelicidin precursor protein hCAP18. It is a multifunctional innate immune effector that acts as an antibiotic, immune modulator, wound healing promoter, and anti-biofilm agent.
LL-37 is present in neutrophils, macrophages, mast cells, epithelial cells, and NK cells — broadly distributed across the innate immune system as a first-line defense against microbial invasion.
Mechanism of Action
Direct Antimicrobial Activity
LL-37 disrupts microbial membranes through electrostatic interactions with negatively charged bacterial, fungal, and viral membranes — inserting into and destabilizing the membrane structure. This mechanism is effective against gram-positive bacteria, gram-negative bacteria, fungi, and certain enveloped viruses.
Anti-Biofilm Properties
LL-37 is one of the most potent natural anti-biofilm agents identified — capable of penetrating and disrupting established biofilms that render chronic infections resistant to conventional antibiotics.
Immune Modulation
Beyond direct antimicrobial activity, LL-37 modulates immune cell function: recruiting monocytes and neutrophils to infection sites, activating dendritic cells, modulating macrophage polarization, and suppressing excessive inflammatory responses.
Wound Healing
LL-37 promotes wound healing through multiple mechanisms: stimulating keratinocyte migration and proliferation, promoting angiogenesis, and modulating the inflammatory phase of healing.
Gut and Skin Microbiome Regulation
Research shows LL-37 plays a role in regulating mucosal immunity in the gut and skin — where it helps maintain the balance between tolerance of commensal organisms and defense against pathogens.
Key Research Findings
Research in chronic wound healing, atopic dermatitis, inflammatory bowel disease, and sepsis shows LL-37 deficiency is associated with worse outcomes, while LL-37 supplementation improves healing and immune function. Emerging research in cancer immunology shows LL-37 can modulate tumor microenvironments.
