Cytokine profile of mice fed with different experimental diets. Mice received different restricted diets: Control (Ctrl), Low protein 3 and 8% (LP 3% and LP 8%, respectively). Serum samples were obtained before infection (∼day 50), and before perfusion (∼day 100) for cytokine measurement. Levels of IFN-γ (A), TNF (B), IL-6 (C), IL-2 (D), IL-4 (E), IL-10 (F), and IL-17 (G) production were measured using the CBA Th1/Th2/Th17 kit. BI: before infection; BP: before perfusion. Results are representative of two independent experiments (n = 6–11 mice per group) and significant differences were determined by one-way ANOVA followed by Holm-Sidak’s multiple comparison test (*p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001; ****p ≤ 0.0001).
