LL-37 – COMPREHENSIVE RESEARCH PEPTIDE FOR INNATE IMMUNITY AND ANTIMICROBIAL SIGNALING STUDIES

Scientific Overview of LL-37

LL-37 is a cationic antimicrobial peptide belonging to the human cathelicidin family, derived from the precursor protein hCAP-18. It plays a central role in innate immune defense and is widely studied in in-vitro and in-vivo models investigating host–pathogen interactions and immune signaling pathways.

In experimental research, LL-37 has been investigated for its involvement in:

• Antimicrobial Activity and Membrane Disruption – interaction with bacterial, viral, and fungal membranes leading to structural destabilization (Dürr et al., 2006)
• Immune System Modulation – regulation of cytokine production and immune cell recruitment in inflammatory signaling pathways (Mookherjee et al., 2006)
• Barrier Function and Tissue Repair – study of epithelial cell response, wound healing processes, and angiogenic signaling (Heilborn et al., 2003)

LL-37 serves as a critical research peptide for understanding innate immunity, inflammatory regulation, and peptide-mediated host defense mechanisms.
