LL-37 is the only human cathelicidin antimicrobial peptide, consisting of 37 amino acids beginning with two leucine residues (hence its name). It is produced by immune cells including neutrophils, macrophages, and epithelial cells throughout the body, particularly at barrier surfaces such as the skin, lungs, and gastrointestinal tract. LL-37 represents a critical component of the innate immune system's first line of defense and has been extensively studied for its antimicrobial, immunomodulatory, and wound-healing properties. Its role in host defense has made it one of the most important peptides in the field of innate immunity research.
