LL-37 is a 37-amino acid cationic peptide derived from the C-terminal region of the human cathelicidin antimicrobial protein hCAP18. As the only known cathelicidin-derived peptide in humans, LL-37 has been the subject of extensive research literature focused on innate immune signaling and host defense pathways.

In research models, LL-37 has been studied for its activity against a broad range of microbial targets, its interactions with bacterial membranes, and its effects on immune cell signaling at the cellular level. Investigations have explored its receptor binding profile, including activity at formyl peptide receptor 2 (FPR2), and its influence on cytokine and chemokine pathways in laboratory settings.

LL-37 has also been examined in research contexts focused on wound-healing signaling, angiogenesis pathways, and inflammation-related markers. Published studies have characterized its structural properties, membrane interactions, and downstream effects on immune and tissue-related markers across multiple research designs.
