FIG. 3.

Effects of dexamethasone on cells stimulated with PMA-A23187. Cells were incubated overnight in the presence of various concentrations of dexamethasone and were stimulated with PMA-A23187. Cells were harvested 4 h later for assessment of IL-4 (a) and IL-5 (b) mRNA levels. Supernatants were collected 30 min after activation for determination of β-hexosaminidase secretion (c). Data are expressed as a percentage of the values for the samples from cells given no dexamethasone (dex). Each value represents the mean and SEM for three (a) or two (b and c) separate experiments.
