Abstract
The normal cellular prion protein, designated PrPC, is a membrane glycoprotein expressed most abundantly in brains, particularly by neurons, and to a lesser extent in non-neuronal tissues including lungs. Conformational conversion of PrPC into the amyloidogenic isoform is a key pathogenic event in prion diseases. We recently found that PrPC has a protective role against infection with influenza A viruses (IAVs) in mice by reducing reactive oxygen species in the lungs after infection with IAVs. The anti-oxidative activity of PrPC is probably attributable to its function to activate anti-oxidative enzyme Cu/Zn-superoxide dismutase, or SOD1, through regulating Cu content in lungs infected with IAVs. Oxidative stress could play a pivotal role in the pathogenesis of a wide range of viral infections. Here, we introduce our and others’ studies on the role of PrPC in viral infections, and raise the attractive possibility that PrPC might be a novel target molecule for development of anti-oxidative therapeutics against not only IAV infection but also other viral infections.
