• Immune Response: N-specific IgG (mostly IgG2a) (Shi et al., 2006)

Mouse Response

• Host Strain: Balb/c (Shi et al., 2006)
• Vaccination Protocol: 20 μg of intramuscular vaccine injection (Shi et al., 2006)
• Immune Response: Production of N-specific IgG antibodies (paricularly IgG2a), Lymphocyte proliferation, Production of IFN-γ, IL-2, IL-4, Increased CD4+ and CD8+ levels (Shi et al., 2006)

Mouse Response

• Vaccination Protocol: DNA-coated gold particles were prepared and delivered to the shaved abdominal regions of mice using a helium-driven gene gun (Bio-Rad) with a discharge pressure of 400 lb/in2. C57BL/6 mice were immunized with 2 μg of the plasmid encoding N protein. The mice received two boosters with the same dose at a 1-week interval. (Kim et al., 2004)
• Immune Response: Significantly increased neutralizing antibody titer to N protein DNA vaccine and significantl count of INF-gamma CD8_ lymphocytes within splenocytes (Kim et al., 2004)
• Challenge Protocol: Challenge Protocol: Vaccinated mice challenged with DNA encoding N and challenged these mice with Vac-N or Vac-WT (Recombinant vaccinnia virus expressing SARS N protein or wild-type vaccinia virus, respectively) intranasally or intravenously 1 week after the last vaccination (Kim et al., 2004)
• Efficacy: reduced viral titer load(Kim et al., 2004)
