Quorum sensing is an intercellular communication system that allows bacteria to control gene expression in a cell population density-dependent manner. P. aeruginosa possesses two quorum-sensing systems termed las and rhl. The las and rhl quorum-sensing systems are comprised of the LuxRI homologs LasRI and RhlRI, respectively (9). Quorum sensing inhibitors (QSI) are compounds that interfere with QS pathways, reduce expression of QS-controlled genes and attenuate infecting bacteria. As such compounds do not affect the growth of bacteria, these molecular entities pose lower selective pressure on bacteria and lower the risk of resistance development. Quorum sensing inhibitors effectively downregulate the QS regulatory system. ...

Article CAS PubMed PubMed Central Google Scholar Zhang Y, ... P.aeruginosapossesses three integrated quorum sensing circuits, known as las, rhland the Pseudomonas Quinolone System (pqs). The lasand rhlsystems are reliant on N-acylhomoserine lactones (AHLs), whereas the pqssystem utilises alkylquinolone (AQ) derived signal molecules. In Pseudomonas aeruginosa, the Las and Rhl systems function in tandem with the Las system at the top and these two systems are interconnected by Pseudomonas quinoline signal. Quorum sensing in... In this study, we prepare synthetic molecules and analyze them for inhibition of the Pseudomonas quorum-sensing receptors LasR and RhlR. Our most effective compound, meta-bromo-thiolactone, not only prevents virulence factor expression and biofilm formation but also protects Caenorhabditis elegans and human A549 lung epithelial cells from quorum-sensing–mediated killing by Pseudomonas ... Natural quorum sensing inhibitors effectively downregulate gene expression of Pseudomonas aeruginosa virulence factors Appl Microbiol Biotechnol. 2019 Apr;103(8):3521-3535. doi: 10.1007/s00253-019-09618-0. Epub 2019 Mar 9. Authors Syed A K S Ahmed 1 ... Quorum sensing (QS) is a cell-cell communication mechanism, regulates the biofilm formation and virulence factors that endow pathogenesis in various bacteria including P. aeruginosa. In this study, we identified and evaluated quorum sensing inhibitors (QSIs) from plant-based natural products against P. aeruginosa. A cell‐to‐cell communication mechanism known as quorum sensing (QS) has been found to play a role in P. aeruginosa biofilm formation. Because both QS and biofilms are impacted by the surrounding environment, understanding the full involvement of cell‐to‐cell signalling in establishing these complex communities represents a challenge.
