General description

Chemical structure: peptide

Application

LL-37 is used to study host defense mechanisms.

Biochem/physiol Actions

LL-37 is a muntifunctional host defense peptide with antibacterial, antiviral, and immunomodulating activities. It is the only cathelicidin-type peptide found in human. In addition to its antimicrobial activities, LL-37 has been found to regulate inflammation and neutralize lipopolysaccharides from Gram-negative bacteria.

Bce-like systems mediate resistance against antimicrobial peptides in Firmicutes bacteria. Lactobacillus casei BL23 encodes an "orphan" ABC transporter that, based on homology to BceAB-like systems, was proposed to contribute to antimicrobial peptide resistance. A mutant lacking the permease subunit was
