Popis: Interferons or oxidized glutathione were found to induce double-stranded RNA-dependent protein kinase activity in mouse L cells that phosphorylates the α subunit of eukaryotic peptide initiation factor 2. A mixture of leukocyte/fibroblast interferons as well as immune interferon induced the protein kinase and also suppressed virus replication in the L cells. Oxidized glutathione was equally effective in inducing protein kinase activity, but it did not induce an antiviral state in these cells. The data suggest that a simple cause and effect relationship does not exist between protein kinase induction and the establishment of the antiviral state in a cell that is responsive to the antiviral effects of interferon.
