Literature

Research context

LL-37 is released by proteinase-3 cleavage of the hCAP-18 precursor. Published work covers membrane permeabilisation of Gram-positive and Gram-negative bacteria, LPS neutralisation, biofilm disruption assays, and chemotactic signalling through FPRL1 on immune cells. It is the reference antimicrobial peptide in most comparative studies.

Documented research areas
