    LL-37 Peptide Full English Introduction

    Basic Information

    • CAS No.: 154947-66-7
    • Full name: LL-37 (human cathelicidin antimicrobial peptide)
    • Source: Cleaved from precursor protein hCAP18, the only cathelicidin peptide naturally produced in human body
    • Composition: 37 amino acids, named after two initial leucine residues (LL) + total 37 amino acids
    • Molecular weight: ~4493 Da
    LL-37 is the only human cathelicidin peptide. It targets bacterial cell membranes to eliminate pathogens directly, while regulating skin immune response and stimulating skin cell regeneration.
    1. Disrupt membrane structure of gram-positive bacteria, gram-negative bacteria and fungi to achieve broad-spectrum antibacterial effect 
    2. Suppress overactive inflammatory factors to relieve redness, swelling and irritation
    3. Activate keratinocyte and fibroblast proliferation, accelerate wound tissue repair
    4. Scavenge free radicals to reduce oxidative skin aging

    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
