LL-37
LL-37 is a human antimicrobial peptide commonly discussed in innate immunity, host-defense, inflammation, and antimicrobial research.
Overview
Research Summary
LL-37 is an antimicrobial and host-defense peptide that is commonly discussed in innate immune research. It is associated with antimicrobial activity, immune signaling, inflammation, epithelial barriers, wound-related models, and host-pathogen interactions. Because this topic overlaps with infection and immune claims, the page should clearly avoid suggesting that LL-37 treats infections or replaces medical care.

Evidence
Evidence Snapshot
LL-37 has strong mechanistic and review literature as an antimicrobial and immunomodulatory peptide. Human treatment claims for infections, immune disorders, or inflammatory disease should not be made on this site.
Limitations
What To Keep In Mind
- Antimicrobial activity in research does not equal infection treatment.
- Immune modulation can be context-dependent.
- Some inflammatory conditions involve complex LL-37 biology.
- Medical claims around infections should be avoided.
Responsible Research
Notes
- Do not say LL-37 treats infections.
- Do not recommend it for immune conditions.
- Keep the page focused on innate immunity and antimicrobial peptide research.
