Matching Together Living Cells and Prototissues: Will There Be Chemistry?

ChemBioChem, Volume 25, Issue 18, September 16, 2024.
In the field of tissue engineering, the combination of synthetic and living tissues could be the turning point. In this work we review examples of hybrid protocell/living cell and prototissue/living cell systems, focusing on the chemistry that makes the integration between non‐living and living matter efficient.

The role of antifungals agents on Candida glabrata biofilms matrix composition [PDF]

, 2010
Candida glabrata was considered, for years, a relatively non-pathogenic saprophyte of the normal flora of healthy individuals and as no causative agent of serious infection in humans.

N‐acyl homoserine lactone cell–cell diffusible signalling in the Ralstonia solanacearum species complex

Molecular Plant Pathology, Volume 25, Issue 8, August 2024.
Pathogens of the Ralstonia solanacearum species complex (RSSC) regulate virulence gene expression via four interconnected quorum‐sensing (QS) signalling systems ensuring a timely response in different environmental settings. Abstract Ralstonia solanacearum species complex (RSSC) includes soilborne bacterial plant pathogens with worldwide distribution ...

Nanomaterials Regulate Bacterial Quorum Sensing: Applications, Mechanisms, and Optimization Strategies

Advanced Science, Volume 11, Issue 15, April 17, 2024.
This review focuses on the specific mechanisms by which nanomaterials regulate bacterial quorum sensing in the signal supply and signal transduction cascade processes. Furthermore, based on the influencing factors of nanomaterial itself and environment, optimization strategies to enhance the QS regulatory activity are comprehensively summarized.

N-Acyl Homoserine Lactone Production by Klebsiella pneumoniae Isolated from Human Tongue Surface [PDF]

, 2012
Bacteria communicate by producing quorum sensing molecules called autoinducers, which include autoinducer-1, an N-hexanoyl homoserine lactone (AHL), and autoinducer-2.

Potential of the quorum‐quenching and plant‐growth promoting halotolerant Bacillus toyonensis AA1EC1 as biocontrol agent

Microbial Biotechnology, Volume 17, Issue 3, March 2024.
Bacillus toyonensis AA1EC1 promotes plant growth and protects plants against phytopathogenic bacteria through quorum quenching mechanisms based on the enzymatic degradation of AHLs. Abstract The use of fertilizers and pesticides to control plant diseases is widespread in intensive farming causing adverse effects together with the development of ...

Dual control of hydrogen cyanide biosynthesis by the global activator GacA in Pseudomonas aeruginosa PAO1 [PDF]

, 2017
The global response regulator GacA of Pseudomonas aeruginosa PAO1 positively controls the production of the quorum sensing signal molecule N-butanoyl-homoserine-lactone (C4-HSL) and hence the synthesis of several C4-HSL-dependent virulence factors ...

Phenotypic and genotypic characterisation of Burkholderia cenocepacia J2315 mutants affected in homoserine lactone and diffusible signal factor-based quorum sensing systems suggests interplay between both types of systems [PDF]

, 2013
Many putative virulence factors of Burkholderia cenocepacia are controlled by various quorum sensing (QS) circuits. These QS systems either use N-acyl homoserine lactones (AHL) or cis-2-dodecenoic acid ("Burkholderia diffusible signal factor'', BDSF) as ...
