We found that positive macrophages to L. mexicana-induced oxidative burst increased from ~34.1 to 58.6% (P < 0.001) by PPARγ agonist at 120 min after infection compared to non-treated macrophages, whereas treatment with PPARβ/δ agonist increased from ~34.1 to 40.32% (P < 0.05) (Figures 6(a) and 6(b)). The gene discussed is PPARG; the disease is infection.
