LL-37 – 5mg Peptide

Human cathelicidin–derived peptide studied for innate immune defense, microbial interaction, and inflammatory signaling pathways.

LL-37 is a synthetic peptide derived from the human cathelicidin family, representing the only known human cathelicidin identified to date. As a cationic, amphipathic peptide, LL-37 has been widely studied in laboratory settings for its role in innate immune defense mechanisms, host–pathogen interactions, and cellular signaling processes involved in inflammation and barrier integrity.

In preclinical and in vitro research models, LL-37 has been examined for its ability to interact with microbial membranes and modulate immune signaling pathways associated with host defense. Scientific studies frequently explore how LL-37 influences chemotactic signaling, cytokine modulation, epithelial responses, and wound-response pathways at the cellular level, making it a core peptide in immunology and microbiology research.

Beyond direct microbial interaction, LL-37 has been shown in research literature to play a role in immune cell activation and inflammatory regulation, contributing to broader investigations into how innate immune peptides coordinate defense responses while maintaining tissue integrity. These multifaceted activities have positioned LL-37 as a reference peptide in studies examining immune balance, inflammatory control, and epithelial barrier function.

Because of its well-characterized structure, broad biological activity profile, and extensive presence in published research, LL-37 is commonly utilized in laboratories focused on innate immunity, microbial resistance models, inflammation biology, and cellular defense signaling.
