Webb12 apr. 2024 · One of the best-studied cell-to-cell communication mechanisms is quorum sensing. Chemical signaling through quorum sensing is involved in regulating the bacterial group behaviors, often required for host colonization. However, most microbial-host interactions regulated by quorum sensing are studied in pathogens. Here, we will focus … 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]. greater valley school greater noida address
