Big picture of how interferon-induced genes launch antiviral defenses revealed

When viruses attack, one molecule more than any other fights back. Interferon triggers the activation of more than 350 genes, and despite the obvious connection, the vast majority have never been tested for antiviral properties. A team of researchers, led by scientists from Rockefeller University, for the first time has carried out a comprehensive, systematic evaluation of the antiviral activity of interferon-induced factors. The findings, published online today in the journal Nature, are a first step toward unraveling how these naturally occurring molecules work to inhibit viruses.
