RT Journal Article T1 Patents on Quorum Quenching: Interfering with Bacterial Communication as a Strategy to Fight Infections A1 Romero Bernárdez, Manuel A1 Acuña, Laura A1 Otero Casal, Ana María K1 Acylase K1 Agonist K1 AHL K1 AI-2 K1 Antagonist K1 Bacterial communication K1 Biofilm K1 Lactonase K1 Peptide K1 Quorum quenching K1 Quorum sensing K1 Signal K1 Virulence AB Numerous bacterial functions, such as virulence and biofilm formation, are controlled by a cell densitydependent communication mechanism known as Quorum Sensing (QS), in which small diffusible molecules are released, allowing bacteria to coordinate their behavior once a minimal effective quorum has been reached. The interference with these signaling systems, also known as Quorum Quenching (QQ), represents a promising strategy to tackle bacterial infections. The growing interest in this approach is reflected by the increasing number of patents within the field (45 up to now), especially in the last few years, as shown by patent applications published since 2009. The fact that biofilm formation is also controlled by QS systems expands the application of QQ to clinically-relevant biofilms such as those responsible for periodontal disease. Moreover, since biofilms increase bacterial resistance to antimicrobials, QQ could represent a new way to fight some of the most recurrent human pathogens, such as nosocomial multiresistant strains, and this deserves further exploration, especially through more proofs of concept. In this article we review the best known QS and QQ systems to date and we describe recent patents on the interference with this type of bacterial communication.
