LL-37 Peptide for Research | Cathelicidin Antimicrobial (AMP) | Elite Peptide Supply
LL-37 is the only member of the Cathelicidin family of antimicrobial peptides (AMPs) found in humans. Produced by key immune cells such as macrophages and polymorphonuclear leukocytes (white blood cells), LL-37 serves as a critical molecular model for studying the body’s innate defense mechanisms.
Beyond its direct bactericidal properties, LL-37 is an “alarmin”—a signaling molecule that alerts the immune system to tissue damage or pathogen invasion. Researchers prioritize this peptide for its multifaceted influence on inflammation, wound healing, and cellular signaling in complex environments like the corneal and conjunctival epithelia.
Key Research Areas for LL-37:
- Antimicrobial Action: Extensively studied for its broad-spectrum bactericidal and viral inhibitory effects as part of mucosal innate immunity.
- Wound Recovery: Research investigates LL-37’s role in promoting re-epithelialization and tissue repair signaling.
- Autoimmune Studies: Scientists examine the peptide’s involvement in the pathogenesis of autoimmune diseases where immune signaling may be dysregulated.
- Oncology Research: Investigated for its diverse roles in cancer cell signaling, where it may exhibit varying effects depending on the tumor environment.
- Ocular Health: A primary focus for studying protection against bacterial and viral ocular infections at the mucosal level.
