Abstrakt: IgE-receptor dependent, but not A23187-induced, histamine release from passively sensitized chopped human lung tissue, or from a dispersed lung cell population obtained from the tissue after enzymatic digestion, is reduced after incubation overnight of cells/ tissue with the glucocorticosteroid budesonide (10-7M). Since the inhibitory effect of budesonide is reduced in the continuous presence of diluted reagin-rich serum used for passive sensitization, but not in the presence of heat-inactivated serum, it is suggested that the glucocorticosteroid acts by reducing the binding of IgE-antibody to the target cell(s).
