3. Supplemental Digital Content 1 - Figure 1: Differential effects of MPA, tacrolimus and everolimus upon human CD4+ T cells in vitro polarization and IL17 production. a/ Effects of MPA, tacrolimus and everolimus upon the transcription of CD4+ cell subsets-related genes after two days of T cell activation. CD4+ T cells were activated following the same protocol, alone or in the presence of MPA and tacrolimus at a final concentration of 3µg/mL and 5µg/L, respectively. A comparative RT-PCR of the relative expression of CD4+ T cell subsets-related genes was then realized. *, P<0.05; **, P<0.01; ***, P<0.005 (Comparison of means, Wilcoxon signed-rank test, .Prism 5; Graph Pad Softwares, San Diego, Calif). Bars represent medians. b/ Effects of MPA, tacrolimus and everolimus upon IL17 secretion. CD4+ T cells from 18 healthy volunteers were activated for 48 hours alone or in the presence of MPA and tacrolimus at a final concentration of 3µg/mL and 5µg/L. Frequency of IL17-producing CD4+ T cells among 50 000 activated CD4+ T cells was measured by ELISpot. The figure presents the comparison of the frequency of IL17A. *, P<0.05; **, P<0.01; ***, P<0.005 (Comparison of means, Wilcoxon signed-rank test, .Prism 5; Graph Pad Softwares, San Diego, Calif).
