Cellular Signaling Analysis shows antiviral, ribavirin-mediated ribosomal signaling modulation.

ABSTRACT: As antiviral drug resistance develops and new viruses emerge there is a pressing need to develop strategies to rapidly develop antiviral therapeutics. Here we use phospho-specific flow cytometry to assess perturbations of many different cellular signaling pathways during treatment with drug combinations that are highly effective in blocking Herpes simplex virus type 1 (HSV-1) infection. We discovered two antiviral drug combinations act on distinct signaling pathways, either STAT1 or S6 phosphorylation, to block HSV-1 infection. We focused on upregulation of S6 phosphorylation by HSV-1 infection, and our subsequent finding that ribavirin antagonizes this upregulation of S6 phosphorylation. We go on to show that the S6 kinase inhibitor SL0101 blocks HSV-1 replication in vitro and in an in vi
