mRNA expression of TIGIT and CD226 in the PBMCs and spleens from mice infected with the T. gondii RH strain, as assessed by qRT-PCR. A: Data obtained from PBMCs. B: Data obtained from the spleen. Values are the means from triplicate measurements, with data denoting means ± SDs; three independent experiments were performed with five mice per group. *p < 0.05, **p < 0.01 and ***p < 0.001 (compared to the control).
