Treatment with inhaled FP (500 µg) for 2 h significantly increased GR nuclear translocation (Figure 7A) and concomitantly decreased the number of nuclear GATA-3 immunoreactive peripheral blood T cells (37%±4.2% versus 58.2%±4.95%, p = 0.016, W = 28.0, Wilcoxon's rank test) compared with placebo as measured by immunocytochemistry (Figure 7A and 7B).
