LL-37 5mg

LL-37 is a multifunctional cationic antimicrobial peptide that forms part of the human innate immune defense system. As the only cathelicidin-derived peptide found in humans, LL-37 plays a central role in antimicrobial defense, immune regulation, and tissue repair.

Comprising 37 amino acids, LL-37 is produced primarily by neutrophils, macrophages, and epithelial cells, and is expressed in various tissues including the skin, lungs, and gastrointestinal tract. Researchers value LL-37 for its broad biological activity, making it a key focus in studies relating to immunity, inflammation, and cellular repair mechanisms.
