Stimulation of Dex-treated T cells is not associated with enhanced apoptosis. Dex-treated and control naive CD4+ T cells were stimulated with anti-CD3 or anti-CD3 plus IL-2 and stained with (a) annexin V and (b) propidium iodide 24, 48, and 72 hours later. The number of positively stained cells was assessed by flow cytometry. Results are shown as mean ± SD of duplicate samples. Control, medium alone.
