ham Biosciences, Amersham, UK) as previously described [34]. Cells were stimulated with anti-CD3/CD28 (1 µg/ml each) for 1 h at 37°C to stimulate Th2 cytokine release in the presence or absence of FP (10−12 to 10−8M). Cytospins were prepared and GATA-3 localization determined by confocal microscopy as previously described [12].
