Quorum sensing controls Vibrio cholerae multicellular aggregate formation

open access: yeseLife, 2018
Bacteria communicate and collectively regulate gene expression using a process called quorum sensing (QS). QS relies on group-wide responses to signal molecules called autoinducers.

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...

Mean-field equation for a stochastic many-particle model of quorum-sensing microbial populations

open access: yes, 2018
We prove a mean-field equation for the dynamics of quorum-sensing microbial populations. In the stochastic many-particle process, individuals of a population produce public good molecules to different degrees.

Cloning, Expression And Characterization Of Ahlinactivating aiiA Gene Homologue In Escherichia coli [PDF]

open access: yes, 2014
Cell-to-cell communication pathway of single-celled microbes is usually coordinated by quorum sensing (QS) system mediated by signal molecules. This cell density-dependent system plays a vital role in functional coordination of most pathogenic ...

Effect of CSLM imaging rate on biofilms of P. aeruginosa and S. aureus [PDF]

open access: yes, 2015
Biofilms are sessile communities of bacteria that can be found in an wide range of environments. Their inhabitants are phenotypically distinct from plank- tonic bacteria and are capable of forming complex, three-dimensional structures.

A structural perspective on the mechanisms of quorum sensing activation in bacteria

open access: yesAnais da Academia Brasileira de Ciências, 2015
Bacteria are able to synchronize the population behavior in order to regulate gene expression through a cell-to-cell communication mechanism called quorum sensing.

One can’t stand on its own: Are non-luminescence traits necessary for V. fischeri colonization of E. scolopes? [PDF]

open access: yes, 2012
Vibrio fischeri and Euprymna scolopes squid establish mutualistic symbiosis and select for each other in the natural environment. V. fischeri provides bioluminescent camouflage for E. scolopes while E. scolopes provides nutrients for V. fischeri.

Enzymatic Assays to Investigate Acyl-Homoserine Lactone Autoinducer Synthases [PDF]

open access: yes, 2017
Bacteria use chemical molecules called autoinducers as votes to poll their numerical strength in a colony. This polling mechanism, commonly referred to as quorum sensing, enables bacteria to build a social network and provide a collective response for fighting off common threats.

Centesimal Composition, Bioactive Compounds, and Antimicrobial Properties of White (Hylocereus undulatus) and Red (Hylocereus polyrhizus) Pitayas

open access: yesJournal of Food Science, Volume 91, Issue 3, March 2026.
ABSTRACT This study investigated the centesimal composition, physicochemical properties, bioactive compounds, antimicrobial activity, and anti‐quorum sensing (QS) potential of red pulp (RP; Hylocereus polyrhizus) and white pulp (WP; Hylocereus undulatus) pitayas.

Secondary metabolites and their exploitation in medicine [PDF]

open access: yes, 2009
Many of the medicinal products available today are derived from secondary metabolites. Plants remain the main source of such therapeutic agents but other sources are being explored and exploited.
