Initially, we performed a correlation analysis using the Spearman correlation test for data of parasitemia (T. cruzi), behavioral and cognitive changes, neurochemical alterations (TBARS, GABA and glutamate, BDNF), and serum inflammatory profiles (TNF, NO), comparing NI controls, Veh-treated, PTX-, Bz- and Bz + PTX-treated T. cruzi-infected mice. The gene discussed is BDNF; the disease is parasitic infectious disease.
