The cellular prion protein, termed PrPC, is a glycoprotein abundantly expressed in brains and to a lesser extent in non-neuronal tissues including lungs. It was reported that PrPC is expressed by lung epithelial cells in mice, and that it may play a protective role against lethal infection with influenza A viruses (IAVs). This may occur by regulating Cu content and superoxide dismutase activity, eventually reducing oxidative stress in infected lungs. Anti-oxidative therapeutics have been demonstrated to protect mice from lethal infection with IAVs. Therefore, PrPC might be a new target molecule for development of IAV therapeutics. Here, we introduce the anti-viral mechanism of PrPC against IAV infection and discuss perspectives of PrPC-targeting therapeutics against IAV infection.
