Research Abstract

In this study, to establish novel antiviral strategies against highly pathogenic viruses, we analyzed the action mechanism of the antiviral cellular factor, Tetherin, and its antiviral spectrum. We demonstrated that Tetherin has the antiviral activities against influenza and Hazara viruses as well as Lassa and Marburg viruses.
