Mapping quorum sensing onto neural networks to understand collective decision making in heterogeneous microbial communities.

Physical biology Jul 19, 2017
Microbial communities frequently communicate via quorum sensing (QS), where cells produce, secrete, and respond to a threshold level of an autoinducer (AI) molecule, thereby modulating gene expression. However, the biology of QS remains incompletely ...

A synthetic multi-cellular network of coupled self-sustained oscillators.

PloS one Jun 29, 2017
Engineering artificial networks from modular components is a major challenge in synthetic biology. In the past years, single units, such as switches and oscillators, were successfully constructed and implemented. The effective integration of these pa...

Spatial dispersal of bacterial colonies induces a dynamical transition from local to global quorum sensing.

Physical review. E Dec 21, 2016
Bacteria communicate using external chemical signals called autoinducers (AI) in a process known as quorum sensing (QS). QS efficiency is reduced by both limitations of AI diffusion and potential interference from neighboring strains. There is thus a...

Quantitative determination of AI-2 quorum-sensing signal of bacteria using high performance liquid chromatography-tandem mass spectrometry.

Journal of environmental sciences (China) May 27, 2016
Autoinducer 2 (AI-2), an important bioactive by-product of the LuxS-catalyzed S-ribosylhomocysteine cleavage reaction in the activated-methyl-cycle, has been suggested to serve as a universal intra- and inter-species signaling molecule. The developme...

Prediction and analysis of quorum sensing peptides based on sequence features.

PloS one Mar 17, 2015
Quorum sensing peptides (QSPs) are the signaling molecules used by the Gram-positive bacteria in orchestrating cell-to-cell communication. In spite of their enormous importance in signaling process, their detailed bioinformatics analysis is lacking. ...

Nanoscale Robots Exhibiting Quorum Sensing.

Artificial life Jan 1, 2019
Multi-agent systems demonstrate the ability to collectively perform complex tasks (e.g., construction, search, and locomotion) with greater speed, efficiency, or effectiveness than could a single agent alone. Direct and indirect coordination methods ...
