The effect of adenosine on the modulation of retinal cAMP levels was assessed in several mammalian species including mouse, rat, guinea pig and rabbit. Adenosine had no effect when added to incubated rat, mouse and guinea pig retinas. However, levels of cAMP were elevated in dose-dependent manner by adenosine in both light- and dark-adapted incubated rabbit retinas. Isobutylmethylxanthine (IBMX) blocked the elevation elicited by adenosine. Norepinephrine and dopamine also elevated cAMP in incubated rabbit retinas and these effects were not blocked by IBMX. The elevations of cyclic AMP levels produced by adenosine were additive with the effects of dopamine or norepinephrine. These results indicate that an adenosine-sensitive cAMP system exists in rabbit retina, and it is probably distinct from the dopamine and norepinephrine regulated cyclic AMP systems.
