The intracellular parasiteToxoplasma gondiican infect a range of hosts and occasionally causes serious disease in humans. In this Review, Hunter and Sibley summarize recent studies that implicate rhoptry kinases and a dense-granule protein as mediators of acute virulence in the mouse model. They also describe the complex interplay between these parasite effector proteins and the innate immune system.
