Abstract:
The modulation of host cell death pathways by bacteria has been recognized as a major pathogenicity mechanism. Among other strategies, bacterial pathogens can hijack the cell death machinery of host cells by influencing the signalling pathways that converge on the mitochondria. In particular, many bacterial proteins have evolved to interact in a highly specific manner with host mitochondria, thereby modulating the decision between cell life and death. In this Review, we explore the intimate interactions between bacterial pathogens and mitochondrial cell death pathways.
Insights
Bacteria manipulate host cell death by targeting mitochondria. This review details how bacterial proteins interact with mitochondria to control cell fate, impacting disease.
Area of Science:
- Microbiology and Cell Biology
- Pathogenesis and Host-Pathogen Interactions
Background:
- Bacterial pathogenicity often involves manipulating host cell death pathways.
- Mitochondria are key organelles in regulating cell life and death decisions.
- Bacterial pathogens have evolved mechanisms to interfere with host mitochondrial functions.
Purpose of the Study:
- To review the intricate interactions between bacterial pathogens and host mitochondrial cell death pathways.
- To highlight how bacteria hijack mitochondrial signaling to promote survival or virulence.
Main Methods:
- Literature review of studies on bacterial-host interactions.
- Analysis of known bacterial proteins that target mitochondria.
- Examination of signaling pathways converging on mitochondria.
Main Results:
- Bacterial proteins specifically interact with host mitochondria.
- These interactions modulate mitochondrial function and cell death.
- Pathogens exploit these interactions for their own benefit.
Conclusions:
- Targeting mitochondrial cell death is a critical bacterial pathogenicity mechanism.
- Understanding these interactions offers insights into novel therapeutic strategies.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
