LL-37 is a cathelicidin-derived antimicrobial peptide (AMP) central to innate defense. In research settings, it has been studied for:

• Broad-Spectrum Activity: Targets gram-positive and gram-negative bacteria, select viruses, fungi, and biofilms.

• Immune Modulation: Balances pro- and anti-inflammatory cytokines to reduce chronic, non-productive inflammation.

• Tissue Repair: Promotes angiogenesis and keratinocyte migration to support closure of wounds and regeneration of damaged skin and mucosal tissue.

• Barrier Integrity: Supports gut epithelial tight junctions, helping reduce intestinal permeability (“leaky gut”).

• Difficult Sites: Investigational support in chronic wounds, surgical sites, and trauma areas; interest in hard-to-treat, antibiotic-resistant contexts (e.g., MRSA).

Outcomes vary with protocol design, baseline status, and endpoints. LL-37 content here is aligned to Live Hebe’s science-backed voice and intended for research use guidance.
