6981por Verbeke, Frederick, De Craemer, Severine, Debunne, Nathan, Janssens, Yorick, Wynendaele, Evelien, Van de Wiele, Christophe, De Spiegeleer, Bart“…Both Gram-negative and Gram-positive bacteria use this type of communication, though the signal molecules (auto-inducers) used by them differ between both groups: Gram-negative bacteria use predominantly N-acyl homoserine lacton (AHL) molecules (autoinducer-1, AI-1) while Gram-positive bacteria use mainly peptides (autoinducer peptides, AIP or quorum sensing peptides). …”

6989por Fleitas Martínez, Osmel, Rigueiras, Pietra Orlandi, Pires, Állan da Silva, Porto, William Farias, Silva, Osmar Nascimento, de la Fuente-Nunez, Cesar, Franco, Octavio Luiz“…We review here various approaches that are being taken to interfere with quorum-sensing signal production via the inhibition of autoinducer-2 synthesis, PQS synthesis, peptide autoinducer synthesis, and N-acyl-homoserine lactone synthesis. We expect these approaches will lead to the discovery of new quorum-sensing inhibitors that can help to stem the tide of antibiotic resistance.…”
