Abstract
Influenza virus infections represent a big issue for public health since effective treatments are still lacking. In fact, the efficacy of anti-influenza agents is limited by the rapid occurrence of drug resistance. Thus, many efforts have been devoted to identify new therapeutic strategies targeting the virus-host cell interactions. Oxidative stress is a characteristic of some viral infections including influenza. Because antioxidants protect cells from damage caused by reactive oxygen species induced by different stimuli including pathogens, they represent interesting molecules to fight infectious diseases. However, most of the available studies have found that these would-be panaceas could actually exacerbate the diseases they claim to prevent, and have thus revealed "the dark side" of these molecules. This review article discusses the latest opportunities and drawbacks of the antioxidants used in anti-influenza therapy and new perspectives.
