To control quorum sensing in gram-negative bacteria, several kinds of autoinducer analogues were synthesized and examined their agonistic or antagonistic activities against quorum sensing in gram-negative bacteria. N-acyl-L-homocystein thiolactones acted as agonists and N-acyl-cyclopentylamides acted as...

The quorum sensing by Gram-negative bacteria usually proceeds by the production of the aforementioned auto-inducers likeN-acyl-homoserine lactones (AHLs) or cyclodipeptides for signalling purposes (Chamkhi et al., 2020;Shrestha et al., 2020).AHLsare some of the most widely studied quorum sensing...
The term ‘quorum sensing’ (QS) is generally used to describe the phenomenon that bacteria release and perceive signal molecules to coordinate cooperative behaviour in response to their population size. QS-based communication has therefore been consider

The paradigm of quorum sensing in Gram-negative bacteria is the bioluminecence (lux) phenotype found in Photobacterium fischeri, where the synthesis of the homoserine lactone signal pheromone requires the LuxI protein. The LuxR protein can bind the homoserine lactone molecule, resulting in ...
N-acylated-L-homoserine lac- tones (AHLs) and autoinducer AI-2 are the two common classes of autoinducers used by Gram-negative bacteria in their QS system12. With the availability of a numbers of AHL biosensors, this has greatly facilitated the screen- ing of AHL production by using the ...
The autoinducer-2 (AI-2) is a key quorum-sensing signal molecule which regulates bacterial group behaviors and is recognized by many Gram-negative and Gram-positive bacteria. Here we report a synthetic mammalian cell-based microbial-control device that detects microbial chemotactic formyl peptides ...
