Fig. 4.
Concentration-dependence of IL-5 and PAF on PI3K activation in human eosinophils. PI3K activation was detected in human eosinophils (2 × 106) after stimulation with (A) IL-5 (10−11 to 10−9 mol/L) for 5 minutes or (B) PAF (10−8 to 10−6 mol/L) for 1 minute at 37°C. Lane 4 represents the unstimulated control for both experiments. The experiment shown is representative of three other experiments.
