Abstract
HCV-infection induces a state of oxidative stress more pronounced than in many other inflammatory diseases. Here we propose a temporal sequence of events in the HCV-infected cell whereby the primary alteration consists in release of Ca2+ from the ER followed by uptake into mitochondria. This triggers successive mitochondrial dysfunctions leading to generation of ROS and to a progressive metabolic adaptive response. Pathogenetic implications of the model and new opportunities for therapeutic intervention are discussed.
