LL-37 (5mg)

LL-37 (CAP-18) Product Description
LL-37 is a multifunctional antimicrobial peptide that serves as a critical component of the innate immune system. Derived from the C-terminal end of the human cathelicidin protein hCAP-18, this 37-amino acid peptide is produced by various cell types including neutrophils, macrophages, and epithelial cells.

Beyond its direct antimicrobial activities against bacteria, viruses, and fungi, LL-37 exhibits remarkable immunomodulatory functions such as chemotaxis, wound healing promotion, and inflammation regulation. It achieves this versatility by interacting with cell membranes and various receptors, modifying immune cell responses.

Due to its therapeutic potential, LL-37 has become a significant focus in research for developing novel antimicrobial agents, particularly against antibiotic-resistant pathogens, as well as treatments for inflammatory conditions and wound management.
