Cette expression sert a designer les Sept Dormants, mot a mot « les gens de la caverne », par allusion a la sourate du meme nom (Coran, XVII, 9-27). Elle est connue dans tout le monde musulman. Son origine remonte a la legende chretienne des Sept Dormants d’Ephese adolescents qui, lors de la persecution de Dece, furent emmures vifs dans une caverne ...

Simultaneous molecular docking of different ligands to His6-tagged organophosphorus hydrolase as an effective tool for assessing their effect on the enzyme [PDF]
Background Enzymatic hydrolysis of N-acyl homoserine lactones (AHLs), which are signaling molecules responsible for the development of antibiotic resistance in gram-negative bacteria, is a potential solution to overcoming antibiotic resistance problem ...

A rhlI 5′ UTR-Derived sRNA Regulates RhlR-Dependent Quorum Sensing in Pseudomonas aeruginosa [PDF]
N-Acyl homoserine lactone (AHL) quorum sensing (QS) controls expression of over 200 genes in Pseudomonas aeruginosa. There are two AHL regulatory systems: the LasR-LasI circuit and the RhlR-RhlI system.

Effects of gelling agent and extracellular signaling molecules on the culturability of marine bacteria [PDF]
Only 1% of marine bacteria are currently culturable using standard laboratory procedures, and this is a major obstacle for our understanding of the biology of marine microorganisms and for the discovery of novel microbial natural products. Therefore, the

Bacteria use quorum sensing signaling for cell-to-cell communication, which is also important for their interactions with plant hosts. Quorum sensing via N-acyl-homoserine lactones (AHLs) is important for successful symbioses between legumes and nitrogen-

N-acyl homoserine lactones (AHLs) are small signaling molecules used by many Gram-negative bacteria for coordinating their behavior as a function of their population density.

The phenazine pyocyanin is a terminal signalling factor in the quorum sensing network of Pseudomonas aeruginosa [PDF]
Certain members of the fluorescent pseudomonads produce and secrete phenazines. These heterocyclic, redox-active compounds are toxic to competing organisms, and the cause of these antibiotic effects has been the focus of intense research efforts.

This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.

N-acyl homoserine lactones (AHLs) act as quorum sensing signals that regulate cell-density dependent behaviors in many gram-negative bacteria, in particular those important for plant-microbe interactions.
