Quorum Sensing in Food-Borne Bacteria and Use of Quorum Sensing Inhibitors as Food Intervention Techniques

, 2014
In the last few years, significant progress has been made in understanding the virulence, transmission, survival, stress response, and interactions of food-borne bacteria with other microbiota.

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

Advanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Light‐Activated Ruthenium Nanoclusters Reprogram the Metabolic‐Quorum Sensing Axis for Precision Periodontitis Therapy

Advanced Science, EarlyView.
Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.

Quorum sensing in Porphyromonas gingivalis and oral microbial interactions: a scoping review

Frontiers in Oral Health
ObjectivePorphyromonas gingivalis, a major periodontal pathogen, interacts with other oral microbes through quorum sensing, enhancing its growth and virulence, which contributes to periodontitis.

Flavones as Quorum Sensing Inhibitors Identified by a Newly Optimized Screening Platform Using Chromobacterium violaceum as Reporter Bacteria

Molecules, 2016
Quorum sensing (QS) is the process by which bacteria produce and detect signal molecules to coordinate their collective behavior. This intercellular communication is a relevant target for anti-biofilm therapies.

The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

Advanced Science, EarlyView.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...

Screening of quorum sensing and biofilm inhibitors among pseudomonas aeruginosa clinical isolates

, 2022
Quorum sensing (QS) is a process that enables bacteria to communicate using secreted small pheromone-like signaling molecules called autoinducers (AIs). This process enables a population of bacteria to regulate gene expression collectively.

Effects of natural and chemically synthesized furanones on quorum sensing in Chromobacterium violaceum

BMC Microbiology, 2004
Background Cell to cell signaling systems in Gram-negative bacteria rely on small diffusible molecules such as the N-acylhomoserine lactones (AHL). These compounds are involved in the production of antibiotics, exoenzymes, virulence factors and biofilm ...
