In order to multiply, influenza viruses are dependent on cells of a human or animal body. They board those cells, for example all along the lung surface, and their genetic material migrates into the nucleus, where it is replicated. As a result, new viruses come to life. A team led by scientists from the Cells-in-Motion Cluster of Excellence (CiM), University of Münster, has now, for the first time, succeeded in visualizing structures of the viral genome inside of human cells by light microscopy.
