How the Body Fights Against Viruses

Scientists of the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna, together with colleagues of the ETH Zurich, have now shown how double stranded RNA, such as viral genetic information, is prevented from entering the nucleus of a cell. During the immune response against viral infection, the protein ADAR1 moves from the cell nucleus into the surrounding cytoplasm. There it modifies viral RNA to inhibit reproduction of the virus. But how is the human genome protected from inadvertent import of viral RNA into the nucleus? The current study of the research teams from Vienna and Zurich, published in PNAS Plus, sheds the first light on this question.
