Also discussed as: Cathelicidin LL-37
What it is and how it works
LL-37 is a cathelicidin peptide involved in antimicrobial and immune-related biology. Researchers have also studied topical wound-healing formulations. The presence of immune activity does not imply that more activity is always helpful or that an injectable product has the same effects.

Human randomized trial
This label describes the selected source below. It is not a complete ranking of the literature, a safety score, or an approval status.
- Study or assessment
- Miranda et al., 2023 — LL-37 cream in diabetic foot ulcers
- Design
- Randomized, double-blind, controlled topical-treatment trial over four weeks.
- Who or what was studied
- People with mildly infected diabetic foot ulcers.
- What was observed
- The authors reported improved granulation-related healing measures, but not reductions in the measured inflammatory markers or bacterial colonization.
- Limits of interpretation
- The result concerns a topical preparation and a defined wound population. It does not establish general immune enhancement or safety of injectable LL-37.
What the evidence means
Immune activity can have multiple consequences; it should not be described as a universal immune boost.
Approval and regulatory context
Not an FDA-approved immune-boosting medicine.
Safety and uncertainty
Safety gaps and nonclinical concerns exist.
What remains uncertain
Formulation, route, wound type, and measured outcome need to remain attached to the claim. Results should not be stretched from one topical study into a general-purpose wellness intervention.
These summaries are introductory and are not a complete account of the literature, adverse effects, contraindications, or interactions. Absence of a listed risk does not mean absence of risk. Different compounds, formulations, and routes cannot be treated as interchangeable.
