How does interferon prevent viral replication?
Its binding to the plasma membrane triggers the synthesis of serveral enzymes by the cell. If the cell is infected or eventually becomes infected, these enzymes block the synthesis of proteins the virus requires for replication. It must be reemphasized that interferon is not specific. Many, but not all, viruses induce interferon synthesis, and interferon in turn can inhibit the multiplication of many kinds of viruses.
