Figure 5. PTB is not associated with antigen – induced alterations in immunoregulatory cytokines.

Figure 5

Whole blood from PTB, TBL and LTB individuals was stimulated with (A) PPD (10 µg/ml) or (B) ESAT-6 (10 µg/ml) or (C) CFP-10 (10 µg/ml) or (D) anti-CD3 (5 µg/ml) for 72 h, and levels of immunoregulatory cytokines IL-10 and TGFβ were measured by ELISA. Results are shown as net cytokine production over media control. The bars represent geometric means and 95% confidence intervals. P values were calculated using the Kruskal-Wallis test with Dunn's multiple comparisons comparisons (* p<0.05, ** p<0.01, *** p<0.001).
