Scientific Overview

LL-37 is the only human cathelicidin-derived antimicrobial peptide (AMP) identified to date, playing a vital role in innate immunity. Derived from the C-terminal domain of hCAP-18, LL-37 exhibits broad-spectrum antimicrobial activity, direct anti-biofilm effects, and the ability to modulate host immune responses.

In addition to its antimicrobial properties, LL-37 is a key regulator in wound healing, tissue regeneration, and inflammatory balance, and has been studied for its roles in chronic infections, autoimmune skin conditions, and tumor immunology.

Key Research Applications

Innate immune activation and pathogen clearance models
Antibacterial, antiviral, antifungal, and anti-biofilm research
Epithelial wound healing and re-epithelialization studies
Inflammatory skin diseases (psoriasis, rosacea)
Immunomodulation and cytokine expression regulation
Tumor microenvironment, angiogenesis, and apoptosis research
