CTLA-4 blockade does not alter the production of IFN-γ, IL-17, or IL-23 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 CTLA-4 Ig or control Ig is shown as line graphs with each line representing a single TST+ individual (n = 10). Results are shown as net cytokine production over media control. P values were calculated using the Wilcoxon signed rank test.
