The stimulation of adenylate cyclase by dopamine and various beta-adrenergic agonists has been investigated in homogenates from 3 areas of cat brain: the cerebral cortex, cerebellum and hippocampus. The purpose of the study was to determine whether the beta-arenergic receptors coupled to adenylate cyclase could be classified as either beta 1 and beta 2 subtypes in the different regions studied. The stimulation of adenylate cyclase by the beta-adrenergic agonist, (-)isoproterenol (5 X 10(-6) M), was completely blocked by the specific beta-adrenergic antagonist, (p)alprenolol (1-(-5) M), but not by the dopaminergic antagonist, fluphenazine (10(-5) M), whereas the stimulation of adenylate cyclase by (-)epinephrine (10(-4) M) was blocked to varying extents by these two drugs in each of the 3 regions studied. The (-)epinephrine effect was always blocked in the combined presence of (p)alprenolol and fluphenazine. The adenylate cyclase stimulation by (p)epinephrine which is not blocked by (p)alprenolol was due to interaction of (p)epinephrine with a dopaminergic-sensitive adenylate cyclase which has been characterized in cerebral cortex, hippocampus and cerebellum. Regional differences in the affinity of beta-adrenergic-sensitive aden...Continue Reading

Antipsychotic Drugs

Antipsychotic drugs are a class of medication primarily used to manage psychosis (including delusions, hallucinations, paranoia or disordered thought), principally in schizophrenia and bipolar disorder. Discover the latest research on antipsychotic drugs here

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
