Quorum-sensing in Gram-negative bacteria.
It has become increasingly and widely recognised that bacteria do not exist as solitary cells, but are colonial organisms that exploit elaborate systems of intercellular communication to facilitate their adaptation to changing environmental conditions. The languages by which bacteria communicate take the form of chemical signals, excreted from the cells, which can elicit profound physiological ...
متن کاملQuorum sensing in Gram-negative bacteria: small-molecule modulation of AHL and AI-2 quorum sensing pathways.
Numerous species of bacteria employ a mechanism of intercellular communication known as quorum sensing. This signaling process allows the cells comprising a bacterial colony to coordinate their gene expression in a cell-density dependent manner.1-3 Quorum sensing is mediated by small diffusible molecules termed autoinducers that are synthesized intracellularly (throughout the growth of the bact...
متن کاملN-Acylhomoserine Lactones, Quorum Sensing, and Biofilm Development in Gram-negative Bacteria
Many different Gram negative bacteria employ N-acylhomoserine lactones (AHLs) as diffusible signal molecules which enable bacterial populations to co-ordinate gene expression as a function of cell population density. Such co-ordinated community behavior, termed “quorum sensing” (QS) regulates diverse physiological processes including secondary metabolite production, motility, DNA transfer and p...
متن کاملExploiting Quorum Sensing Interfering Strategies in Gram-Negative Bacteria for the Enhancement of Environmental Applications
Quorum sensing (QS) is a widespread intercellular form of communication to coordinate physiological processes and cooperative activities of bacteria at the population level, and it depends on the production, secretion, and detection of small diffusible autoinducers, such as acyl-homoserine lactones (AHLs), auto-inducing oligo-peptides (AIPs) and autoinducer 2. In this review, the function of QS...
متن کاملApplications of small molecule activators and inhibitors of quorum sensing in Gram-negative bacteria.
Quorum sensing is a form of intercellular communication used by many species of bacteria that facilitates concerted interactions between the cells comprising a population. The phenotypes regulated by quorum sensing are extremely diverse, with many having a significant impact upon healthcare, agriculture, and the environment. Consequently there has been significant interest in developing methods...
