About LL-37

LL-37 is a 37-amino acid antimicrobial peptide (AMP) belonging to the cathelicidin family. In biochemical research, it is studied for its multifaceted role in the innate immune response, including its ability to neutralize lipopolysaccharides (LPS) and promote wound healing pathways. Laboratory investigations often center on its antimicrobial properties and its influence on cell migration.
