Human antibody response to Toscana virus glycoproteins expressed by recombinant baculovirus

J Med Virol. 2002 Dec;68(4):615-9. doi: 10.1002/jmv.10227.

Abstract

The arthropod-borne Toscana virus has been associated with acute neurological disease in humans. In this study, the viral envelope glycoproteins were expressed in soluble form in a baculovirus system. The recombinant sGN and sGC proteins were used as viral antigens in a Western blot assay to analyze the specific immune response in sera from patients with recognized virus-associated aseptic meningitis. The anti-glycoprotein and the anti-nucleoprotein N IgG responses were compared by an immunoassay based on the recombinant proteins. In this system, all the sera showed a high reactivity to the N protein, but they differed in the response to the glycoproteins.
