Figure 6. T. cruzi-infected mice have higher serum IL-12 than do HKTC-immunized mice.
A/J mice were infected with T. cruzi (INF), immunized with epimastigote HKTC (HKTC), trypomastigote HKTC (HKTCtct) or PBS (PBS). At 21 d.p.i., sera was collected and IL-12 levels were measured via ELISA. The mean concentration of serum IL-12 is shown. Error bars indicate SEM (nā=ā8 for INF; nā=ā7 for other groups). * P<0.05 compared to the PBS control group.
