CD4+CD25+ T cell depletion causes upregulation of IFN-γ, IL-17, and IL-23 production in TST+ individuals. PBMC production of IFN-γ, IL-17, and IL-23 following 24-h stimulation with PPD (10 μg/ml) or Mtb CFA (10 μg/ml) in the presence of CD4+CD25+ T cell depletion in TST+ (A) or TST− (B) individuals is shown as line graphs with each line representing a single individual (n = 6–10). Results are shown as net cytokine production over media control. P values were calculated using the Wilcoxon signed rank test and only statistically significant P values are shown.
