Surface expression of Fas on γδ T cells after stimulation. (A) Histograms in bold represent Fas staining overlaid on the negative control staining (thin lines) for naïve γδ T cells (i–iv) and activated γδ T cells (v–viii) at different times, i.e., t0 (i and v), t4 (ii and vi), t8 (iii and vii) and t24 (iv and viii) after stimulation. Surface expression of FasL on γδ T cells after stimulation in the absence (B) or presence (C) of CsA. Histograms in bold represent FasL staining overlaid on the negative control staining (thin lines) for naïve γδ T cells (i–v) and activated γδ T cells (vi–x) before activation (i, vi) and at different times, i.e., t0 (ii and vii), t4 (iii and viii), t8 (iv and ix) and t24 (v and x) after stimulation, including treatment with 5 µg/ml of CsA (C) at t8 (i) and t24 (ii).
