FIG 7.

mRNA levels for T cell markers (CD3δ, CD4, and CD8β) are lower during the later stage of reactivation of T. gondii infection in the brains of nude mice that received immune T cells with anti-α4 integrin MAb treatment than in those with the cell transfer with control MAb. Mice were infected, treated with sulfadiazine, and received T cells with treatment with anti-α4 integrin or a control MAb as described in the legend to Fig. 5. mRNA levels for the T cell markers were measured by real-time RT-PCR 6 days after discontinuation of sulfadiazine treatment (see Materials and Methods). *, P < 0.05; **, P < 0.01; ***, P < 0.001. The error bars indicate standard errors.
