LL-37 (Human Cathelicidin) for Research
Technical Overview
LL-37 is a synthetic antimicrobial peptide, the only human cathelicidin, which plays a key role in the body’s first line of defense against pathogens. Researchers study it for its effects on immune function, wound healing and inflammation.
Research applications
- Antimicrobial defense: activity against bacteria, viruses and fungi by disrupting their cell membranes.
- Immune regulation: its role in regulating immune responses and chronic inflammation.
- Wound healing: tissue repair and skin regeneration.
- Inflammation control: how it may modulate inflammatory responses without suppressing immunity.
- Inflammatory skin research: studies related to psoriasis, eczema and other inflammatory skin conditions.
Because immune reactions to threats can also trigger inflammation, scientists examine how LL-37 may help regulate that response while keeping defenses intact. This combination of antimicrobial and immunomodulatory activity makes LL-37 a valuable compound in both dermatology and immunology research.
