Interaction between Intracellular Bacterial Pathogens and Host Cell Mitochondria

Abstract : Mitochondria are essential and highly dynamic organelles whose morphology is determined by a steady-state balance between fusion and fission. Mitochondrial morphology and function are tightly connected. Because they are involved in many important cellular processes, including energy production, cell-autonomous immunity, and apoptosis, mitochondria present an attractive target for pathogens. In this chapter, we explore the relationship between host cell mitochondria and intracellular bacteria, with a focus on mitochondrial morphology and function, as well as apoptosis. Modulation of apoptosis either allows bacteria to establish their replicative niche or supports bacterial dissemination. Furthermore, bacteria can manipulate mitochondrial morphology and function through secreted effector proteins and can also contribute to the establishment of a successful infection, e.g., by favoring access to nutrients and/or evasion of the immune system.
