What Is LL-37?

LL-37 is a naturally occurring peptide derived from the human cathelicidin antimicrobial peptide gene. It is produced through the processing of a larger precursor protein known as hCAP18.

The name “LL-37” originates from its amino acid sequence. The peptide begins with two leucine (L) residues and consists of 37 amino acids in total.

Researchers classify LL-37 as an antimicrobial peptide (AMP), a group of naturally occurring molecules that contribute to innate immune defence and biological communication.

Unlike many specialised signalling molecules, LL-37 is considered multifunctional because it participates in numerous cellular and molecular processes.

The Discovery of LL-37

Scientific interest in antimicrobial peptides increased significantly during the late twentieth century as researchers sought to understand how organisms protect themselves from environmental challenges.

The discovery of LL-37 provided important insights into human innate immunity and peptide-mediated defence systems.

Scientists identified LL-37 as the active peptide fragment derived from hCAP18 and quickly recognised its importance in host defence research.

Since then, LL-37 has become one of the most widely investigated human peptides within immunology, microbiology, and molecular biology.
