Reverse Genetic Generation of Recombinant Zaire Ebola Viruses Containing Disrupted IRF-3 Inhibitory Domains Results in Attenuated Virus Growth In Vitro and Higher Levels of IRF-3 Activation without Inhibiting Viral Transcription or Replication

Abstract excerpt

The VP35 protein of Zaire Ebola virus is an essential component of the viral RNA polymerase complex and also functions to antagonize the cellular type I interferon (IFN) response by blocking activation of the transcription factor IRF-3. We previously mapped the IRF-3 inhibitory domain within the C terminus of VP35. In the present study, we show that mutations that disrupt the IRF-3 inhibitory function of VP35 do...
