DAI Another Way: Necroptotic Control of Viral Infection

Cell Host Microbe. 2017 Mar 8;21(3):290-293. doi: 10.1016/j.chom.2017.01.016.


Interrogation of murine cytomegalovirus (MCMV)-encoded cell-death suppressors revealed that necroptosis functions as a trap door to eliminate virally infected cells. This crucial host defense pathway is orchestrated by the sensing of infection by DAI/ZBP-1, engagement of the kinase RIPK3, and subsequent membrane permeablization by the pseudokinase MLKL.
