1. VanT, a central regulator of quorum sensing signalling in Vibrio anguillarum
Sammanfattning : Many bacteria produce signal molecules that serve in a cell-to-cell communication system termed quorum sensing. This signalling system allows a bacterial population to co-ordinately regulate functions according to their cell number in a defined environment. LÄS MER
2. Stress response and virulence in Vibrio anguillarum
Sammanfattning : Bacteria use quorum sensing, a cell to cell signaling mechanism mediated by small molecules that are produced by specific signal molecule synthases, to regulate gene expression in response to population density. In Vibrio anguillarum, the quorum-sensing phosphorelay channels information from three hybrid sensor kinases VanN, VanQ, CqsS that sense signal molecules produced by the synthases VanM, VanS and CqsA, onto the phosphotransferase VanU, to regulate activity of the response regulator VanO.

3. Cell-to-cell communication and virulence in Vibrio anguillarum
Sammanfattning : Quorum sensing (QS) is a type of cell-to-cell communication that allows the bacteria to communicate via small molecules to coordinate activities such as growth, biofilm formation, virulence, and stress response as a population. QS depends on the accumulation of signal molecules as the bacterial population increases. LÄS MER
4. Functional characterization of the small antisense RNA MicA in Escherichia coli
Sammanfattning : The Escherichia coli small RNA (sRNA) MicA was identified recently in a genomewide search for sRNAs. It is encoded between the genes gshA and luxS in E. coli and its close relatives. The function of sRNAs in bacteria is generally believed to be in maintenance of homeostasis via stress-induced modulation of gene expression. LÄS MER
5. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation
Sammanfattning : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. LÄS MER
