Similarly, the percentage of CD4+T-bet+ cells was higher in clinically cured individuals with pulmonary tuberculosis than in those with active disease, both in cultures without stimulation (P = 0.001, Kruskal-Wallis test followed by Dunn's post hoc test) and with stimulation (P = 0.001, Kruskal-Wallis test followed by Dunn's post hoc test). This evidence concerns the gene CD4 and pulmonary tuberculosis.
