FIG. 7.

Serum IL-6 and IL-10 levels in EV71-infected mice either untreated or treated with anti-IL-6 antibodies postinfection. EV71 infection and anti-IL-6 antibody treatment at day 3 or 6 postinfection were performed as described in the legend of Fig. 3. Four animals per group were sacrificed at the indicated time points, and individual serum samples were collected for IL-6 and IL-10 quantification. Serum samples were diluted at 1:25. The data are expressed as the means ± standard error of the means of the four serum samples per group and per time point. **, P < 0.01, in relation to untreated group.
