Abstract

Membranes prepared from normal rat kidney fibroblasts possess an adenosine receptor of the stimulatory (A2 or Ra) type linked to adenylate cyclase. Homologous desensitization to adenosine A2 agonists is developed upon exposure of the cells to adenosine-NCC, a potent A2 agonist. This desensitization process is followed by a heterologous desensitization which is manifested in a time-dependent reduction of 1-epinephrine and NaF-dependent adenylate cyclase.
