FIG. 1.

Serum IFN-γ levels in infected WT BALB/c mice on day + 12 and day + 21. Treatment was started on day + 12 as described in Table 1, footnote a. No treatment (A) and treatment with anti-IL-10R (B), anti-IL-4 (C), TGF-βRII-Fc (D), and IL-13Rα2-Fc (E) are shown. Hatched bars show corresponding IgG-treated controls. Results are from two experiments and indicate mean ± standard error of the mean (SEM) values for six to seven mice per group. *, P < 0.05 for anti-IL-10R-treated versus day + 21 untreated or IgG-treated mice.
