Abstract
The interaction of isoproterenol with beta-adrenoceptors has been inve stigated in astroglial and neuronal cells isolated from adult rat cere bral cortices. Using the non-selective beta-adrenergic antagonist (H-3 )CGP-12177 as a ligand, binding experiments revealed that both types o f cells exhibit beta-adrenoceptors. However the analysis of the isopro terenol displacement curve indicated that only neuronal cells containe d the high affinity conformational state of the beta-adrenoceptor.
