Abstract

Mitochondria regulate a myriad of cellular functions, but in the context of infection these dynamic organelles are considered exploitable targets for microbes. However, the fact that pathogens have developed strategies to perturb mitochondrial function supports the existence of mitochondrial counterstrategies to defend against pathogens. Our overarching goal is to deepen our understanding of how mitochondria regulate cellular defense against microbes. In this project, we will explore two novel mechanisms of mitochondrial defense during infection with human parasite Toxoplasma.
