Several viruses, including influenza, induce an imbalance of intracellular redox state toward pro-oxidant conditions. Through different mechanisms these alterations contribute both to influenza virus replication and to the pathogenesis of virus-induced disease. At the same time, influenza virus activates several intracellular signaling pathways involved in important physiological functions of the cell. Interestingly, many of these pathways are finely regulated by small changes in intracellular redox state, and the virus-induced redox imbalance might also control viral replication through this mechanism. Here we review the main intracellular redox-sensitive pathways activated upon influenza infection and involved in regulating viral replication.
