Abstract:
:The localization of adenosine receptors labelled with [3H]cyclohexyladenosine ([3H]CHA) and adenosine transport sites labelled with [3H]nitrobenzylthioinosine ([3H]NBI) was examined in striatum and superior colliculus (SC) using radioligand binding and lesioning methods. Striatal kainic acid lesions significantly reduced the number (Bmax) of a single class of high affinity binding sites for [3H]CHA by 50% and that for [3H]NBI by 15% without altering Kd values for either ligand. In SC, enucleations significantly reduced both high and low affinity [3H]CHA binding sites by about 60% while levels of [3H]NBI binding were unaffected. Thus, adenosine receptors are present on striatal interneurons and retinal projections to the SC and some [3H]NBI binding sites are located on striatal interneurons.
