T. cruzi infection modulates AhR expression. WT mice were infected with 1 × 10³ trypomastigotes of the Y strain. Hearts (A) and spleens (B) were harvested, and AhR protein levels were measured by Western blotting at 0 (control; 2 mice), 10 (10 d.p.i.; 3 mice), and 15 (15 dpi; 3 mice) days postinfection. For analysis, data were normalized to GAPDH and β-actin expression. Each point represents the mean ± standard error of the mean (SEM) of data from three independent experiments. **, P < 0.01; *, P < 0.05; N.S, not significant.
