A Host-Produced Autoinducer-2 Mimic Activates Bacterial Quorum Sensing [PDF]
Cell Host and Microbe, 2016 Host-microbial symbioses are vital to health; nonetheless, little is known about the role crosskingdom signaling plays in these relationships. In a process called quorum sensing, bacteria communicate with one another using extracellular signal molecules called autoinducers.
