Model of infection by influenza viruses of normal host cells and cells overexpressing Nrf2. Infection by IVs led to the production of reactive oxygen species (ROS). Redox control against ROS and viral replication are illustrated. The addition of sulforaphane (SFN) or epigallocatechin gallate (EGCG) inhibits the viral infection of IV via activation of the antioxidation pathway [54].
