Fig. 6. IP-10 and MCP-1 levels in YFV-17D-infected mice. Serum levels of (a) IP-10 and (b) MCP-1 were measured in serum from uninfected IFNAR^−/− mice and from IFNAR^−/− mice intramuscularly inoculated with 10⁴ p.f.u. YFV-17D. Serum was collected at 5 days p.i. and disease state was monitored through day 8 p.i., facilitating assignment of disease outcome. Results are shown as mean±sem with three mice per condition and are representative of three independent experiments. Statistically significant differences are indicated by asterisks (P<0.05, Student’s t-test).
