(A) IL-17 production (white bars, left Y-axis) and CD44 expression (grey bars, right Y-axis) of naïve-sorted CD4+ T cells before, one, two, three and four days after allogeneic stimulation with BMDCs (n = 4, ± SEM).

<p>(B) IFN-γ production (white bars, left Y-axis) and CD44 expression (grey bars, right Y-axis) of naïve-sorted CD4^<b>+</b> T cells before, one, two, three and four days after allogeneic stimulation with BMDCs (n = 4, ± SEM). (C) Magnetically sorted CD4^<b>+</b> T cells were stimulated four days with allogeneic BMDCs. Co-cultures were left untreated or were treated with 10 μg/ml αCD44 directly before PMA/ionomycin restimulation (n = 5, <i>M</i> ± SEM, Wilcoxon rank sum test, <i>p</i> = 0.06).
