LL-37 5mg

What Is LL-37?

LL-37 is a human cathelicidin antimicrobial peptide — the only cathelicidin found in the human body. It is a 37-amino acid peptide that plays a critical role in innate immunity, acting as the body's first-line defense against pathogens. Beyond its antimicrobial properties, LL-37 has been shown to modulate immune responses, promote wound healing, and influence inflammatory pathways.

Why Researchers Choose LL-37

• Broad-spectrum antimicrobial — Active against bacteria, fungi, and enveloped viruses in vitro
• Endogenous peptide — Naturally produced by human immune cells (neutrophils, macrophages, epithelial cells)
• Dual function — Both direct antimicrobial activity and immunomodulatory signaling
• Biofilm disruption — Research shows ability to disrupt established bacterial biofilms

Key Research Areas

• Innate immunity and host defense mechanisms
• Antimicrobial peptide resistance studies
• Wound healing and tissue regeneration
• Biofilm disruption and chronic infection models
• Inflammatory regulation (both pro- and anti-inflammatory)
