title: Looks Who's Talking Now.
abstract: In this issue of Cell Host & Microbe, Ismail et al. (2016) demonstrate that damaged epithelial cells release a signal that activates bacterial quorum sensing pathways, providing insight into the chemical interplay between hosts and their microbes. This activity represents a potential mechanism for host modulation of bacteria.
