CD4 and tuberculosis: Similar results were observed in TB-treated patients for CD4+CD25−FoxP3+ and CD4+CD25HighFoxP3+ relative to Th1 cells (CD25−, P = 0.046; CD25High, P = 0.0028, Kruskal-Wallis test followed by Dunn's post hoc test) and Th17 cells (CD25−, P = 0.013; CD25High, P = 0.034, Kruskal-Wallis test followed by Dunn's post hoc test).
