LL-37 is the active, C-terminal fragment derived from the human cationic antimicrobial peptide 18 (hCAP18). It is a key effector molecule in host defense, found in neutrophils and epithelial cells.

This 37-amino-acid peptide (Sequence: LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES) is renowned for its potent, broad-spectrum antimicrobial activity against a wide range of pathogens, including Gram-positive and Gram-negative bacteria, viruses, and fungi.

Beyond its direct antimicrobial effects, LL-37 is a multifunctional immunomodulator. It can influence inflammation, promote wound healing, stimulate angiogenesis, and chemoattract immune cells such as neutrophils and monocytes. Its complex role in the immune system makes it a valuable peptide for research in infectious diseases, immunology, and inflammatory conditions.
