Host monitoring of quorum sensing during Pseudomonas aeruginosa infection

Science, 2019
Spying on bacterial signals Many bacteria produce small molecules for monitoring population density and thus regulating their collective behavior, a process termed quorum sensing.

Optimal Census by Quorum Sensing

PLOS Computational Biology, 2015
Quorum sensing is the regulation of gene expression in response to changes in cell density. To measure their cell density, bacterial populations produce and detect diffusible molecules called autoinducers. Individual bacteria internally represent the external concentration of autoinducers via the level of monitor proteins.

Artificial Symbiosis for Bulk Production of Bacterial Cellulose Composites

Advanced Materials, EarlyView.
Co‐cultivation of the cellulose‐producing bacterium with the microalga enables bulk formation of bacterial cellulose under static incubation, with photosynthetically active oxygen‐generating sites throughout the medium. This symbiotic platform supports 3D cellulosic constructs with geometries dictated by the vessel shape.

QUORUM SENSING AND GROUP SELECTION [PDF]

Evolution, 1998
Bacteria respond to cell density by expressing genes whose products are beneficial to the population as a whole. This response is brought about through the release into the medium of signaling molecules of the class N-acyl homoserine lactones, the concentration of which determines the level of gene expression.

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption

Advanced Materials, EarlyView.
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

Advanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Can the natural diversity of quorum sensing advance synthetic biology?

Frontiers in Bioengineering and Biotechnology, 2015
Quorum-sensing networks enable bacteria to sense and respond to chemical signals produced by neighboring bacteria. They are widespread: over one hundred morphologically and genetically distinct species of eubacteria are known to use quorum sensing to ...

Social cheating in a Pseudomonas aeruginosa quorum-sensing variant

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance In the course of certain chronic infections, Pseudomonas aeruginosa can rewire its quorum-sensing (QS) circuits such that the master transcription regulator LasR is no longer required for the subservient transcription regulator RhlR to ...

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

Advanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Research progress on the mechanisms by which plant-originated quorum sensing inhibitors inhibit pathogenic bacteria of acne

Pifu-xingbing zhenliaoxue zazhi
The main acne-causing bacteria are Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis. Quorum sensing, an important factor for bacterial survival, is closely associated with expression of bacterial virulence factors and biofilm
