WebbQuorum sensing och quorum quenching Bakteriers förmåga att kommunicera med varandra, och vägar att störa denna mekanism för att hämma infektion. Quorum sensing and quorum quenching: The ability of bacteria to communicate with each other, and ways to disrupt this mechanism to reduce infection. Moa Therése Viklund Uppsala 2024 In biology, quorum sensing or quorum signalling (QS) is the ability to detect and respond to cell population density by gene regulation. As one example, QS enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial. Many species of … Visa mer Quorum sensing was first reported in 1970, by Kenneth Nealson, Terry Platt, and J. Woodland Hastings, who observed what they described as a conditioning of the medium in which they had grown the bioluminescent marine … Visa mer Some of the best-known examples of quorum sensing come from studies of bacteria. Bacteria use quorum sensing to regulate certain phenotype expressions, which in turn, … Visa mer A mechanism involving arbitrium has recently been described in bacteriophages infecting several Bacillus species. The viruses … Visa mer Quorum quenching is the process of preventing quorum sensing by disrupting signalling. This is achieved by inactivating signalling enzymes, by introducing molecules that mimic signalling molecules and block their receptors, by degrading signalling molecules … Visa mer Examples Methanosaeta harundinacea 6Ac Methanosaeta harundinacea 6Ac, a methanogenic archaeon, produces carboxylated acyl homoserine lactone compounds that facilitate the transition from growth as short … Visa mer QS is important to plant-pathogen interactions, and their study has also contributed to the QS field more generally. The first Visa mer Social insect colonies are an excellent example of a decentralized system, because no individual is in charge of directing or making … Visa mer

WebbQuorum sensing regulates the expression of PA virulence factors via four major quorum sensing (QS) regulatory proteins [88], namely LasR, RhlR, PqsR and integrated QS (Iqs) R [81]. These have been studied in a few wound/burn models as well as models of acute pneumonia via intranasal administration [88].
