RT Journal Article T1 Interferon induction by avian reovirus A1 Lostalé Seijo, Irene A1 Martínez Costas, José Manuel A1 Benavente Martínez, Francisco Javier K1 Avian reovirus K1 Interferon induction K1 PKR K1 Apoptosis K1 Virus uncoating AB We have previously shown that the replication of avian reovirus (ARV) in chicken embryo fibroblasts (CEF) is more resistant to the antiviral action of interferon (IFN) than the replication of vesicular stomatitis virus (VSV) or vaccinia virus (VV). In this study we examined the capacity of these three viruses to induce the expression of IFN when infecting avian cells. Efficient expression of both type-α and type-β IFNs, as well as of the double-stranded RNA (dsRNA)-activated protein kinase (PKR), takes place in ARV-infected CEF, but not in cells infected with VSV or VV. PKR expression is not directly induced by ARV infection, but by the IFN secreted by ARV-infected cells. IFN induction in ARV-infected cells requires viral uncoating, but not viral gene expression, a situation similar to that reported for apoptosis induction by ARV-infected cells. However, our results demonstrate that IFN induction by ARV-infected CEF occurs by a caspase-independent mechanism PB Elsevier SN 0042-6822 YR 2016 FD 2016-01 LK http://hdl.handle.net/10347/18496 UL http://hdl.handle.net/10347/18496 LA eng NO Lostalé-Seijo, I., Martínez-Costas, J., & Benavente, J.
