LL37

Description

LL-37 is a naturally occurring 37-amino-acid antimicrobial peptide, the only member of the cathelicidin family found in humans, studied extensively in innate immunology research.

In laboratory research, LL-37 is examined for its membrane-disrupting activity against bacterial cell walls as well as its immunomodulatory roles, including chemotaxis of immune cells and modulation of inflammatory signaling.

Researchers studying LL-37 often focus on its dual function: direct antimicrobial activity via membrane permeabilization, and indirect immune regulation through receptor-mediated signaling pathways, making it a compound of interest across both microbiology and immunology research.

LL-37 is also referenced in wound-healing and skin-barrier research due to its expression patterns in epithelial tissue during injury response.

LL-37 is supplied as a laboratory research reagent for investigation into innate immune defense mechanisms and antimicrobial peptide biology.
