LL-37

Description

Scientific Background

LL-37 is a 37-amino-acid peptide produced in the body from the precursor protein hCAP18. It is part of the cathelicidin family, a group of molecules involved in innate immune defense.

Laboratory research has examined LL-37’s interactions with microbes and immune cells, including how it may influence immune-cell recruitment and local signaling. Researchers have also studied its role in tissue repair, where immune activity and the healing process overlap.

LL-37 is a promising research target because it connects two important areas of biology: defense against microbes and the body’s response to tissue damage. Its effects can vary with the biological setting, so research also examines how LL-37 signaling relates to inflammation.
