Abstract:
:The ability of the gut epithelium to defend against pathogens while tolerating harmless commensal organisms remains an important puzzle. In this issue of Cell Host & Microbe, Lee et al. (2015) reveal how pathogen-secreted uracil acts at two steps to induce ROS via the Hedgehog pathway.

For Legionella pneumophila, the bacterium translocates proteins that establish an endoplasmic reticulum (ER)-associated replication compartment.
