Publication TitleRespiratory syncytial virus nonstructural proteins NS1 and NS2 mediate inhibition of Stat2 expression and alpha/beta interferon responsiveness.
AbstractRespiratory syncytial virus (RSV) subverts the antiviral interferon (IFN) response, but the mechanism for this evasion was unclear. Here we show that RSV preferentially inhibits IFN-alpha/beta signaling by expression of viral NS1 and NS2. Thus, RSV infection or expression of recombinant NS1 and NS2 in epithelial host cells causes a marked decrease in Stat2 levels and the consequent downstream IFN-alpha/beta response. Similarly, NS1/NS2-deficient RSV no longer decreases Stat2 levels or IFN responsiveness. RSV infection decreased human but not mouse Stat2 levels, so this mechanism of IFN antagonism may contribute to viral host range, as well as immune subversion.
JournalJ Virol.. 79(14): 9315-9.
SummaryThe natural NS proteins could not be expressed in human cells presumably due to high AT. Synthetic genes were constructed by optimizing the codon usage with mammalian preferred codons and significant expression was obtained for both proteins.
