Novel Linear Polymers Able to Inhibit Bacterial Quorum Sensing

Abstract: Bacterial phenotypes, such as biofilm formation, antibiotic resistance and virulence expression, are associated with quorum sensing. Quorum sensing is a density-dependent regulatory system of gene expression controlled by specific signal molecules, such as N-acyl homoserine lactones (AHLs), produced and released by bacteria. This study reports the development of linear polymers capable to attenuate quorum sensing by adsorption of AHLs. Linear polymers were synthesized using MMA as backbone monomer and methacry… Show more

“…56,57 In contrast, CHX does not affect significantly the viability of murine macrophages, but may have an immunosuppressive effect on exposed macrophages. 58 A recent study demonstrated that cytotoxicity of CHX might be reduced using modified nonequilibrium plasma. Considering these data, plasma-based modification was proposed as a safe option for root canal treatment.…”

“…Cavaleiro et al suggest that the inhibitory effects were caused by attenuation of quorum sensing through sequestration of signal molecules [46]. Quorum sensing (QS) is a fundamental mechanism responsible for microbial communication and several pathogenic behaviors including virulence factors secretion and biofilm formation.…”
