Figure Lengend Snippet: (a) Clinical scores of Il23ra−/−, Il23ra+/− and Il23ra+/+ mice after EAE induction. (b) Clinical scores of mixed bone marrow chimeras following EAE induction. Donor bone marrow genotype is indicated. (c) Flow cytometry of CD4+ cells obtained from the CNS of mixed bone marrow chimeras 11 days post-EAE induction. Genotype of each population is indicated. (d) Proportion of wild-type CD45.1+ or Il23ra−/− CD45.1− CD4+ T cells in the CNS of mixed bone marrow chimeras at indicated time points; data is expressed as mean ratio ± s.d. of CD45.1− to CD45.1+ CD4+ T (wild-type) cells. (e) Absolute numbers of CD4+ T cells in the CNS on day 9 (pre-onset) and day 11 (onset of clinical signs) of EAE. Data shown are each representative of three experiments with 5 mice per group.

Figure Lengend Snippet: (a) Frequency of wild-type or Il23ra−/− CD45.1+CD4+OTII T cells, expressed as percentage of total CD4+ T cells (mean ± s.d), following transfer into wild-type recipients and immunization with OVA(323–339). (b) Delayed type hypersensitivity reaction in mice after transfer of wild-type or Il23ra−/− OTII cells. The increase in foot thickness over the contralateral saline-challenged foot is shown. (c) Time course of Intracellular IL-17 in OTII cells from dLN assessed by flow cytometry after ex vivo stimulation with PMA + ionomycin on indicated days post-immunization. (d) Intracellular Foxp3 expression in OTII cells assessed on days 5 and 7 post-immunization (e) Flow cytometry for phosphorylated STAT3 in OTII cells after 15 minute stimulation with indicated cytokines 4 days post-immunization. (f) Flow cytometry of Cre-deleted Stat3flox/flox CD4+ cells following second stimulation with anti-CD3 in the presence of IL-23. IL-17 is shown as percentage of GFP+ and GFP− cells on each plot. All data shown are representative of at least 3 independent experiments having 4 to 5 mice per group.

Figure Lengend Snippet: (a–e) Analysis of phenotype of wild-type or Il23ra−/− CD45.1+CD4+OTII T cells after transfer into wild-type recipients and immunization with OVA(323–339). (a) Flow cytometry for cell surface expression of CD44, CCR7 and CD62L on wild-type and Il23ra−/− OTII T cells (shaded histograms) overlaid with total CD4+ cells for comparison (clear histograms) at day 7 post-immunization. b) Surface IL-7Rα expression on wild-type (shaded histogram) and Il23ra−/− (clear histogram) OTII cells from dLN. c) RT-PCR analysis of IL-7Rα expression in OTII+ cells sorted by flow cytometry from dLN; values are normalized to ubiquitin expression. As a control, total OTII–CD4+ cells were isolated at the same time from recipients of the indicated OTII cells. Data shown are mean ± s.d. of two groups of samples each containing 5 mice per condition. d) Surface CD27 expression on OTII cells in dLN and blood. e) Frequency of wild-type and Il23ra−/− OTII cells (as proportion of total CD4+ cells) in blood at indicated time points post immunization. Data shown are representative of 3 experiments with similar results.
