Quorum Sensing in Microbial Virulence
Cell-to cell communication occurs via a signaling pathway referred to as quorum sensing. There are four main types of these systems according to the chemical nature of signal molecules used by microorganisms to elicit expression of target genes in response to environmental stimuli or need of microbial communities. Type I system acts by using acyl homoserine lactones as signals to trigger the ex...

1386 JEM Vol. 203, No. 6, 2006 Helpless without SAP CD4+ T cells that lack the adaptor protein SAP are little help to B cells, according to Cannons and colleagues on page 1551. But their unhelpful nature does not result from a failure to produce T helper (Th)-2 cytokines, as the authors had previously thought. The absence of SAP wreaks havoc on the immune system. SAP—the adaptor that links the ...
متن کاملTaking advantage of injustice
What, if anything, is wrong with taking advantage of people’s unjust circumstances when they both benefit from and consent to the exchange? The answer, some believe, is that such exchanges are wrongfully exploitative. I argue that this answer is incomplete at best, and elaborate a different one: to take advantage of injustice is to become complicit in its reproduction. I also argue that the cas...
متن کاملQuorum sensing
although it is fair to say that the problem is still not solved. How is colour constancy achieved? It is still something of a mystery as to how your visual system achieves colour constancy, but scientists do agree that there is more than one mechanism involved. All mechanisms in some way require comparisons of the reflected light from different locations across the scene; colour constancy is a ...
متن کاملQuorum-sensing signals and quorum-sensing genes in Burkholderia vietnamiensis.
Acyl-homoserine lactone (acyl-HSL) quorum sensing is common to many Proteobacteria including a clinical isolate of Burkholderia cepacia. The B. cepacia isolate produces low levels of octanoyl-HSL. We have examined an environmental isolate of Burkholderia vietnamiensis. This isolate produced several acyl-HSLs. The most abundant species was decanoyl-HSL. Decanoyl-HSL in B. vietnamiensis cultures ...
