What is LL-37?
LL-37 is a 37-amino-acid peptide (its name comes from its two initial leucines). Besides its direct action on microbial membranes, in the literature it is associated with modulation of the immune response, so it is studied as an antimicrobial and immunomodulatory peptide.
Research context
Research on LL-37 covers innate immunity, antimicrobial activity and the modulation of inflammation in cellular and preclinical models.
These findings belong to the field of research and do not constitute evidence of efficacy in humans. LL-37 is offered for research use only.
