Fig. 3. IL-10 suppresses IFNγ expression when promoting Th2 differentiation.

Fig. 3

In vitro polarised Th0 cells were cultured with αCD3, αCD28 and IL-2 only, and Th1 cells with the addition of IL-12, for 4 days with or without exogenous IL-10. a The percentage of IFNγ+ CD44hi CD4+ T cells measured in Th0 (top) and Th1 (bottom) cultures. b The concentration (pg/ml) of IL-5 and IL-13 measured in culture supernatants of in vitro polarised Th0 cells cultured as above and with or without anti-IFNγ. c The concentration (pg/ml) of IL-5, IL-13 and IFNγ measured in culture supernatants of in vitro polarised Th1 cells cultured with or without exogenous IL-10. Graphed data are shown with mean ± 1 SD and are representative of two independent experiments with n = 5 per experiment. Statistical significance was calculated by Student’s t test and one-way ANOVA with Tukey’s post-test for multiple comparisons between groups (Significance *p < 0.05, **p < 0.01, ****p < 0.0001).
