Research Applications

LL-37, the human cathelicidin antimicrobial peptide, disrupts bacterial membranes and exhibits broad-spectrum activity against bacteria, fungi, and enveloped viruses.
Modulates innate immunity by chemoattracting neutrophils and monocytes and by regulating Toll-like receptor signaling.
Promotes keratinocyte migration and angiogenesis, supporting research on cutaneous wound healing and tissue repair.
Studied for its ability to inhibit and disrupt bacterial biofilms in chronic-infection research models.
