In vitro studies on the effects on granular gland secretion in Xenopus laevis skin of stimulation and blockade of alpha and beta adrenoceptors of myoepithelial cells.
Authors:C H Holmes  P S Moondi  R R Rao  M Balls
Abstract:Secretion from the granular glands of Xenopus laevis skin was stimulated by alpha-adrenergic agonists, an effect which was blocked by alpha-adrenergic antagonists and inhibited by beta-adrenergic agonists, db-cAMP and diazoxide. The inhibition by isoprenaline and salbutamol, but not that by diazoxide, was blocked by a beta-adrenergic antagonist. It is concluded that the myoepithelial cells surrounding the secretory compartment of the granular glands bear alpha and beta adrenoceptors, and that the beta receptors comprise, or at least include beta2 receptors.
