Abstract: These results provide evidence that adenosine agonists inhibit 3H-NE release in the iris/ciliary body via prejunctional adenosine A1 receptors linked to Gi/o-protein. However, the expression of this response was dependent on the frequency of neuronal stimulation. Hence, prejunctional adenosine A1 receptors may act to selectively limit high-frequency neurotransmission.
