 Understanding the Cathelicidin Peptide

LL-37 is the only human member of the cathelicidin family of antimicrobial peptides. It is an amphipathic, alpha-helical peptide composed of 37 amino acids, with the sequence LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES . It is cleaved from the C-terminus of the human cathelicidin protein, hCAP18, and plays a fundamental role in the innate immune system .

Scientists study LL-37 for its diverse and potent biological activities, including:

• Broad-Spectrum Antimicrobial Activity: It directly disrupts the membranes of bacteria, fungi, and certain enveloped viruses, serving as a first line of defense against pathogens .

• Immune Modulation: It acts as a chemoattractant for immune cells like neutrophils, monocytes, and T-cells, recruiting them to sites of infection or injury . ll 37 peptide for sale

• Wound Healing Promotion: It stimulates angiogenesis (new blood vessel formation) and re-epithelialization, accelerating the repair of damaged skin and tissue .

• Neutralization of Endotoxins: It binds to and neutralizes lipopolysaccharide (LPS), a potent endotoxin released from Gram-negative bacteria, thereby reducing excessive inflammation .

• Biofilm Inhibition: Research indicates it can inhibit the formation of bacterial biofilms and disrupt existing ones, which is critical for studying chronic infections .

It is essential to state clearly: LL-37 peptide is supplied strictly for research and laboratory use only. It is not for human consumption or medical application.

The Science Behind LL-37: A Research Overview

LL-37 is a cornerstone of innate immunity research, acting as a multifunctional “host defense peptide” that directly combats pathogens while orchestrating broader immune responses .

:How Does LL-37 Work?

LL-37’s mechanisms are complex and context-dependent, reflecting its role as both an antimicrobial and an immunomodulator. Its primary research-relevant actions include:

1. Membrane Disruption (Antimicrobial Action): Its cationic (positively charged) and amphipathic structure allows it to bind to the negatively charged membranes of microbes. It then inserts into the membrane, forming pores and causing lethal leakage of cellular contents . ll 37 peptide for sale

2. Receptor-Mediated Signaling (Immunomodulation): It binds to and activates various receptors on host cells, including FPRL-1 (formyl peptide receptor-like 1) and P2X7 purinergic receptors . This triggers signaling cascades that influence cell migration, proliferation, and cytokine release.

3. Chemotaxis: Through receptor activation, it directs the migration of immune cells to sites of inflammation, linking the initial antimicrobial response to adaptive immunity .

4. Angiogenesis and Wound Healing: It directly stimulates the formation of capillary-like structures in endothelial cells and promotes the migration and proliferation of keratinocytes, accelerating wound closure in research models .

Key Research Context and Resources

• Innate Immunity Research: LL-37 is a benchmark molecule for studying host defense peptides. Researchers can find foundational data through resources like the   and , which index thousands of peer-reviewed studies on its structure, function, and role in diseases from psoriasis to chronic wounds .

• Structural and Chemical Information: For detailed chemical and pharmacological data,  provides a comprehensive entry for LL-37, including its sequence, molecular weight (4493.3 g/mol), and known targets . This body of work underscores the critical need for high-purity, reliable peptides for reproducible research.
