Identification and Characterization of Quorum-Quenching Activity of N-Acylhomoserine Lactonase from Coagulase-Negative Staphylococci

open access: yesAntibiotics, 2020
N-Acylhomoserine lactones (AHLs) are used as quorum-sensing signals in Gram-negative bacteria. Many genes encoding AHL-degrading enzymes have been cloned and characterized in various microorganisms.

Revealing the Bacterial Quorum-Sensing Effect on the Biofilm Formation of Diatom Cylindrotheca sp. Using Multimodal Imaging

open access: yesMicroorganisms, 2023
Diatoms contribute to carbon fixation in the oceans by photosynthesis and always form biofouling organized by extracellular polymeric substances (EPS) in the marine environment. Bacteria-produced quorum-sensing signal molecules N-acyl homoserine lactones

SdiA, an N-acylhomoserine lactone receptor, becomes active during the transit of Salmonella enterica through the gastrointestinal tract of turtles. [PDF]

open access: yesPLoS ONE, 2008
LuxR-type transcription factors are typically used by bacteria to determine the population density of their own species by detecting N-acylhomoserine lactones (AHLs).

Production of both l‐ and d‐ N‐acyl‐homoserine lactones by Burkholderia cepacia and Vibrio fischeri

open access: yesMicrobiologyOpen, 2021
Quorum sensing (QS) is a complex process in which molecules, such as l‐N‐acyl‐homoserine lactones (l‐AHLs), are produced as essential signaling molecules allowing bacteria to detect and respond to cell population density by gene regulation.

The AHL- and BDSF-dependent quorum sensing systems control specific and overlapping sets of genes in Burkholderia cenocepacia H111. [PDF]

open access: yesPLoS ONE, 2012
Quorum sensing in Burkholderia cenocepacia H111 involves two signalling systems that depend on different signal molecules, namely N-acyl homoserine lactones (AHLs) and the diffusible signal factor cis-2-dodecenoic acid (BDSF). Previous studies have shown

Gram-negative quorum sensing signalling enhances biofilm formation and virulence traits in gram-positive pathogen Enterococcus faecalis

open access: yesJournal of Oral Microbiology, 2023
Acyl-homoserine lactones (AHLs) are typical quorum-sensing molecules of gram-negative bacteria. Recent evidence suggests that AHLs may also affect gram-positives, although knowledge of these interactions remains scarce.

Deciphering the Symbiotic Significance of Quorum Sensing Systems of Sinorhizobium fredii HH103 [PDF]

open access: yes, 2020
Quorum sensing (QS) is a bacterial cell-to-cell signaling mechanism that collectively regulates and synchronizes behaviors by means of small diffusible chemical molecules.

Bacterial Quorum Sensing Molecules Promote Allergic Airway Inflammation by Activating the Retinoic Acid Response

open access: yesiScience, 2020
Summary: IgE and IgG1 production in the type 2 immune response is the characteristic feature of an allergic reaction. However, whether bacterial molecules modulate IgE and IgG1 production remains obscure.

Synthesis and biological evaluation of novel N-α-haloacylated homoserine lactones as quorum sensing modulators [PDF]

open access: yes, 2014
Novel N-α-haloacylated homoserine lactones, in which a halogen atom was introduced at the α-position of the carbonyl function of the N-acyl chain, have been studied as quorum sensing (QS) modulators and compared with a library of natural N-acylated ...

Chemotaxis of C. reinhardtii Towards AHLs [PDF]

open access: yesThe Young Researcher, 2020
Quorum sensing is a widespread phenomenon in various environments, allowing organisms to display symbiosis, pathogenicity, etc. This mechanism has recently been of great interest with the newfound discovery that quorum sensing not only occurs in ...
