LL-37 is a 37 amino acid long antimicrobial peptide that belongs to the cathelicidin family. Cathelicidin peptides are natural antimicrobial peptides that are amphiphiles, that is one end of the molecule is attracted to water while the other end is attracted to fats and proteins. LL-37 is the only peptide of the cathelicidin family found in humans and is an important part of the human immune system as it can fight a variety of pathogens – it’s part of the first line of defense when the body is injured or there is an infection. It may help boost immune system function, accelerate wound healing, reduce tissue inflammation, suppress cancer growth, and promote bone repair.
