Breaking down bacterial communication: a review of quorum quenching agents
Future Journal of Pharmaceutical Sciences, 2023 Background Bacterial cells communicate via small extracellular molecules that facilitate gene expression which is dependent on cell density and this mechanism is known as Quorum Sensing (QS).

Engineering quorum-quenching enzymes [PDF]
, 2018 Biofilms are structured communities of bacteria that adhere to surfaces and shield bacteria from hostile surroundings. They are implicated in 75% of all infections in humans and are difficult to treat.

Evolution of Resistance to Quorum Quenching in Digital Organisms [PDF]
Artificial Life, 2012 Quorum sensing (QS) is a collective behavior whereby actions of individuals depend on the density of the surrounding population. Bacteria use QS to trigger secretion of digestive enzymes, formation and destruction of biofilms, and, in the case of pathogenic organisms, expression of virulence factors that cause disease. Investigations of mechanisms that

Fake talk in bacteria: Quorum quenching in dental infections
, 2023 embargoed_20260416Bacteria make up 78% of our planet’s living species and among them are present the main enemies of mouth health. Caries, plaque, and periodontitis are the most common diseases of the oral cavity and the main cause for them is the Gram ...

Effect of quorum quenchers on virulence factors production and quorum sensing signalling pathway of non-mucoid, mucoid, and heavily mucoid Pseudomonas aeruginosa [PDF]
, 2022 Quorum quenching (QQ), a mechanism which inhibits, interferes or inactivates quorum sensing, has been investigated for control of biofilms instigated by quorum sensing process. Application of quorum quenchers (QQs) provides the possibility to investigate

Quorum-Sensing Regulation of Antimicrobial Resistance in Bacteria
Microorganisms, 2020 Quorum sensing is a cell-to-cell communication system that exists widely in the microbiome and is related to cell density. The high-density colony population can generate a sufficient number of small molecule signals, activate a variety of downstream ...

Advanced Science, EarlyView.The ER's continuous tubular network is maintained by ER‐shaping proteins whose mutation or dysregulation contributes to neurodegenerative diseases. Here, we show that ER morphology sets the speed of Ca2+ store replenishment between firing events. Disrupting ER continuity slows intra‐ER Ca2+ redistribution from extracellular refill (SOCE) sites, driving

Mathematics in Applied Sciences and Engineering, 2022 We extend a previously presented mesoscopic (i.e. colony scale) mathematical model of the reaction of bacterial biofilms to antibiotics. In that earlier model, exposure to antibiotics evokes two responses: inactivation as the antibiotics kill the ...

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control
Advanced Science, EarlyView.A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...
