Guanylate-binding proteins (GBPs) confer protection against intracellular pathogens. In this issue of Cell Host & Microbe, Wandel et al. (2017) report that cytosolic Shigella becomes trapped within a GBP coat that prevents bacterial cell-to-cell spread. However, this defense mechanism is counteracted by the bacterial E3 ubiquitin ligase IpaH9.8.
