Partners with a killer: Metabolic signaling promotes inflammatory cell death.

ABSTRACT

In this issue of Cell, Evavold et al. (2021) report that mTOR Complex 1 (mTORC1), a metabolic signaling complex, controls reactive oxygen species (ROS) production in mitochondria, which in turn promotes inflammatory cell death mediated by gasdermin D (GSDMD). This provides a new mechanistic connection between metabolic signaling and inflammatory cell death.
