WebbMore recently, it’s become clear that many types of bacteria engage in a mode of cell-cell signaling called quorum sensing. In quorum sensing, bacteria monitor the density of the population (the number of other bacteria in the area) based on chemical signals. When the signaling reaches a threshold level, all the bacteria in the population ... Webb2 jan. 2024 · Quorum sensing was first described as the communication process bacteria employ to coordinate changes in gene expression and therefore, their collective behavior in response to population density. Emerging new evidence suggests that quorum sensing can also contribute to the regulation of immune cell responses.
