- Immune system regulation
- Inflammatory response
- Wound healing and tissue repair
Its broad activity makes it highly valuable in host defense and immune research.
Mechanism of Action: Antimicrobial and Immune Regulation
LL-37 functions through multiple pathways that contribute to both direct pathogen defense and immune modulation.
Direct Antimicrobial Activity
- Disrupts microbial cell membranes
- Neutralizes bacteria, viruses, and fungi in research models
- Acts as a first-line defense molecule
Immune System Modulation
- Regulates immune cell activity
- Enhances pathogen recognition
- Supports coordinated immune responses
Anti-Inflammatory and Pro-Inflammatory Balance
- Modulates cytokine production
- Helps balance immune activation
- Supports resolution of inflammation
Wound Healing and Tissue Repair
- Promotes cell migration and proliferation
- Supports re-epithelialization
- Enhances tissue regeneration processes
This dual antimicrobial and immunomodulatory function makes LL-37 highly unique.
