The present study was undertaken to evaluate the effect of fenoterol, a selective beta 2-adrenergic agonist, on basophil histamine release. Fenoterol at 10(-7) to 10(-3) M did not inhibit the release of histamine induced by Dermatophagoides farinae extract (D.f.) from leukocytes from allergic patients sensitive to mite. Similarly, there was no suppression of histamine release induced by anti-IgE and formyl-methionyl-leucyl-phenylalanine under the influence of fenoterol. Fenoterol caused a slight inhibition of the calcium ionophore A23187-induced histamine release at 10(-3) M with % inhibition of 11.8 +/- 2.4 (means +/- SEM, P less than 0.05). There was no synergism between fenoterol and theophylline in inhibiting D.f.-induced histamine release. Fenoterol did not suppress the release of histamine induced by antigen at low as well as high levels of release. Based on the data on the effect of fenoterol on IgE-mediated histamine release, it was concluded that in contrast to a human lung mast cell system, the beta-adrenergic receptor-adenylate cyclase system is not a control mechanism in IgE-mediated basophil histamine release.
