Flow cytometric analysis of (type I) IL-1R, IL-2R (CD25), and IL-6R expression on T cells pretreated with DEX (0.1 μmol/L; right panels) or a corresponding volume of ethanol (left panels) and stimulated with PHA (5 μg/mL) + PMA (5 ng/mL; dark tracings). Light tracings represent cytokine receptor expression by PHA + PMA-stimulated cells; the first (light) tracing represents background fluorescence. Shown is a representative of three individually performed experiments.
