What reaction do interferons cause?

1. interferons bind to receptors on neighboring cells 2. this induces the production of antiviral proteins, antiviral state activated 3. antiviral proteins are activated when bound to double stranded RNA 4. enzymes 2.5-oligoadenylate synthetase and protein kinase R are activated 5. causes inhibition of protein synthesis and mRNA degradation 6. viral replication is inhibited
