Regarding Th2 responses, we observed that the TB-treated patients had a significantly higher percentage of CD4+IL-4+ cells than did those presenting active disease (P = 0.005, Kruskal-Wallis test followed by Dunn's post hoc test), although this difference was not statistically significant when analyzing the isolated expression of GATA-3 (Figures 2(h) and 2(i)). This evidence concerns the gene IL4 and tuberculosis.
