Core Biological Functions

1. Broad-spectrum Antimicrobial Effect

As cationic amphipathic peptide, it binds negatively charged microbial membranes and breaks membrane structure to kill pathogens directly:

Gram-positive & Gram-negative bacteria
Fungi, enveloped viruses and parasites
Penetrate & destroy bacterial biofilms, hard for bacteria to generate drug resistance compared with common antibiotics

2. Neutralize Endotoxin & Regulate Inflammation

It binds LPS (bacterial endotoxin) to block TLR2/TLR4 inflammatory signaling, suppress overproduction of inflammatory factors to relieve sepsis and excessive inflammatory response.

3. Immune Modulation

Chemoattract neutrophils, monocytes and T cells to infection sites to boost innate immunity
Balance immune activation, mediate communication between innate and adaptive immune system

4. Promote Wound Healing & Tissue Repair

Stimulate migration and proliferation of keratinocytes & fibroblasts to accelerate wound closure
Induce angiogenesis (new blood vessel growth) to supply nutrients for damaged skin/mucosa repair
Deficiency of LL-37 leads to hard-to-heal chronic ulcers

5. Additional Research Directions

Skin barrier protection, relieve skin inflammatory lesions
Anti-tumor research (induce apoptosis of certain tumor cells)
Mucosa defense for respiratory, gastrointestinal and urinary tracts
