Studies & key findings
- LL-37 is the sole human cathelicidin, a 37-amino-acid cationic amphipathic peptide cleaved from the precursor hCAP18; it exerts broad-spectrum antimicrobial activity against gram-positive and gram-negative bacteria, fungi, and viruses via membrane permeabilization, pore formation, and intracellular target disruption — in addition to neutralizing bacterial LPS.
- In wound healing, LL-37 is strongly expressed at acute wound edges (peak at 48 h) and markedly absent in chronic ulcer epithelium; antibody-mediated blockade of LL-37 in ex vivo human skin significantly inhibits re-epithelialization, confirming a causal role via EGFR transactivation that activates STAT3 and Snail/Slug transcription factors to drive keratinocyte migration.
