Abstract

Toscana virus (TOSV) is a phlebotomus-transmitted virus that belongs to the family Bunyaviridae and causes widespread infections in humans; about 30% of these cases result in aseptic meninigitis. In the present study, it was shown that TOSV is an inducer of beta interferon (IFN-beta), although its non-structural protein (NSs) could inhibit the induction of IFN-beta if expressed in a heterologous context. A recombinant Rift Valley fever virus expressing the TOSV NSs could suppress IFN-beta expression in infected cells. Moreover, in cells expressing NSs protein from a cDNA plasmid, IFN-beta transcripts were not inducible by poly(I : C). Unlike other members of the family Bunyaviridae, TOSV appears to express an NSs protein that is a weak antagonist of wFN induction. Characterization of the interaction of TOSV with the IFN system will help our understanding of virus-host cell interactions and may explain why the pathogenesis of this disease is mostly mild in humans.
