Figure Lengend Snippet: CCR6 expressed on IFNγ + IL-17A − CD4 + memory T cells is functional. A. Expression of CXCR3 and CCR6 gated on CD4 + CD45RO + memory T cells. B, C. Median fluorescence intensity (MFI) of CCR6 (B) and CXCR3 (C) in CD4 + CD45RO + memory T cells expressing combinations of CCR6, IFNγ and IL-17A. Repeated measures ANOVA with Bonferroni's multiple comparison test (n = 5); * = p < 0.05, ** = p < 0.01, *** = p < 0.001. All other comparisons were non-significant (p > 0.05). D, E. Purified CD4 + T cells were migrated in a transwell in response to the indicated concentrations of CCL20 (D) or CXCL12 (E). The migrated and non-migrated fractions were then stimulated with PMA and ionomycin before determining IFNγ and IL-17 expression, allowing calculation of the migration of each subset. Data represent the mean and SEM of three independent experiments.
