For decades, mitochondria have been considered a major intracellular source of reactive oxygen species (ROS). Mitochondrial ROS have been viewed as a negative factor, contributing to the damage of cellular components. More recent data point to a more physiological role of mitochondrial-produced ROS in mitochondria-cell communication and intra- and extracellular signaling [1].
The eventual unraveling of the complex and powerful mitochondrial ROS detoxication system resulted in a concept that mitochondria are more a sink than a source of ROS [2,3]. However, our research indicates that mitochondria are a ROS buffering system that can maintain the intracellular level of ROS in relation to the metabolic circumstances.
In this presentation, I will briefly summarize the state of knowledge on the sources and regulation of ROS production and scavenging in mitochondria and present experimental data on mitochondrial ROS-buffering properties.
