About LL-37
LL-37 is a 37-amino acid cationic antimicrobial peptide (AMP) derived from the C-terminal end of the human cathelicidin antimicrobial protein (hCAP-18). As an endogenous component of innate immune research, it is investigated in preclinical models for its roles in microbial membrane research, immune cell signalling, and inflammatory pathway studies.
Primary areas of investigation
- Antimicrobial peptide research
- Microbial membrane interaction studies
- FPR2 receptor signalling
- Pattern recognition receptor research
- Chemotaxis cell models
- LPS neutralisation studies
Mechanism
Research into LL-37 examines its direct interaction with microbial membrane systems and the modulation of innate immune signalling pathways. In experimental systems, it is investigated for its association with bacterial membrane integrity research through its amphipathic alpha-helical structure. It is also studied for its interaction with Formyl Peptide Receptor 2 (FPR2) and other pattern recognition receptor signalling cascades.
