SnapShot: Bacterial Quorum Sensing
Cell, 2018 Quorum sensing (QS) is a chemical communication process that bacteria use to orchestrate group behaviors. QS involves the production, release, and population-wide detection of signaling molecules called autoinducers. QS-controlled behaviors are unproductive when undertaken by a single bacterium but become effective when performed by the group.

Advanced Materials Technologies, EarlyView.We developed a flexible multi‐material printing strategy that employs sequential printing with different printers. This combined use of printers expands the accessible material scope. Moreover, incorporating Xolography as a sequential step enables support‐free, contactless printing, thereby enhancing structural design flexibility beyond conventional ...

Reversible Signal Binding by the
mBio, 2011 Many members of the LuxR family of acyl-homoserine lactone (acyl-HSL)-dependent quorum-sensing transcriptional activators are thought to have the unusual characteristics of requiring the signal ligand during polypeptide synthesis to fold into an active ...

Pseudomonas aeruginosa quorum sensing molecules correlate with clinical status in cystic fibrosis [PDF]
, 2015 Pseudomonas aeruginosa produces quorum sensing signal molecules that are potential biomarkers for infection. A prospective study of 60 cystic fibrosis patients with chronic P. aeruginosa, who required intravenous antibiotics for pulmonary exacerbations,

Quorum sensing with pheromones [PDF]
Nature Microbiology, 2019 The vast majority of fungi reproduce sexually and use secreted pheromones to signal to each other. A study now shows that these signalling molecules in the fungal plant pathogen Fusarium oxysporum activate a density-dependent autocrine signal that controls asexual spore germination.

Effect of Local Population Uncertainty on Cooperation in Bacteria
, 2017 Bacteria populations rely on mechanisms such as quorum sensing to coordinate complex tasks that cannot be achieved by a single bacterium. Quorum sensing is used to measure the local bacteria population density, and it controls cooperation by ensuring ...

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.
