observed that adenosine A1 receptor antagonist CPT decreased the concentration of both<br />

adenosine and dopamine by 40%. Adenosine A1 and dopamine D2 receptors are colocalized in<br />

dopaminergic nerve terminals and their interaction is known to modulate the concentration of<br />

dopamine. When we administered both D2 receptor agonist and A1 receptor antagonist together,<br />

the concentration of adenosine has been restored, even slightly increased, but dopamine<br />

concentration remained decreased.<br />

Our results suggest that adenosine A1 receptors play an important role in mediating the<br />

interaction between adenosine and dopamine in caudate-putamen.<br />
