[Participation of the adenylate cyclase system in inductive synthesis of acetylcholinesterase in the brain].
The enhancement of the brain acetyl cholinesterase (ACHE) activity in rats by the intraventricular injection of adrenaline or dibutiryl analogue cyclic adenosine-3',5'-monophosphate (cAMP) was shown to be due to the enzyme inductive synthesis. ACHE induction manifests itself more in the subcortical white matter than in the cortex. The stimulating effect of adrenaline on the ACHE activity is suppressed under the beta-adrenoreceptor block, while the cAMP effect remains unchanged. On the contrary, the block of the alpha-adrenoreceptors stimulates the enzyme synthesis induction. The effects of adrenaline and cAMP are of the same direction and are realized through the beta-adrenoreceptors. The enhancement of ACHE activity during the block of the alpha-adrenoreceptors is accounted for by the elimination of their inhibitory influence on the beta-adrenoreceptors.
