Quorum Sensing System (QS)

Target: QS
Molecular classification: Cell-to-cell signaling pathway, Regulatory network, LuxR-type receptors, Two-component systems (histidine kinases/response regulators), Signaling pathway

Overview

Quorum sensing (QS) is a cell-to-cell communication mechanism used primarily by bacteria to detect and respond to changes in population density through the regulation of gene expression. This system enables bacteria to coordinate collective behaviors that are most effective when performed by groups, such as virulence, biofilm formation, bioluminescence, sporulation, competence, conjugation, and antibiotic production. Targeting QS is a promising antimicrobial strategy.

Mechanism of action

Inhibition of autoinducer synthesis, degradation of autoinducers, or blocking autoinducer receptors.
