Expression of the structural proteins of dengue 2 virus and yellow fever virus by recombinant vaccinia viruses
Abstract
Vaccinia virus recombinants were constructed which contained cDNA sequences encoding the structural region of dengue 2 virus (PR159/S1 strain) or yellow fever virus (17D strain). The flavivirus cDNA sequences were expressed under the control of the vaccinia 7.5k early/late promotor. Cultured cells infected with these recombinants expressed immunologically reactive flavivirus structural proteins, precursor prM and E. These proteins appeared to be cleaved and glycosylated properly since they comigrated with the authentic proteins from dengue 2 virus- and yellow fever virus-infected cells. Mice immunized with the dengue/vaccinia recombinant showed a dengue-specific immune response that included low levels of neutralizing antibodies. Immunization of mice with the yellow fever/vaccinia recombinant was less effective at inducing an immune response to yellow fever virus and in only some of the mice were low titers of neutralizing antibodies produced.
