Supersensitivity of Amylase Secretion from Rat Parotid Tissue—Its Selective Nature for the β2-Adrenergic Response

Abstract
In rat parotid tissue, amylase secretion and accumulation of cyclic AMP were not selective responses to the different beta-subtypes, beta 1 and beta 2. However, the supersensitivity of the amylase secretory response induced by brief pretreatment with beta-agonist was due specifically to a beta 2-adrenergic response.
