Most influenza viruses enter human or animal cells through specific pathways on the cells’ surface. Researchers at the University of Zurich have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species—and potentially jump between animals and humans.
