  • Title: Autoradiographic evidence that intrastriatal administration of adenosine A(1) receptor antisense oligodeoxynucleotide decreases adenosine A(1) receptors in the rat striatum and cortex.

    Journal: Brain Res Mol Brain Res; 1999 Oct 01; 72(2):226-30. PubMed ID: 10529481.
    Abstract:
    In this study, the effect of a phosphorothioated A(1) adenosine receptor antisense oligodeoxynucleotide on A(1) receptor density and mRNA in the striatum and cortex of rats was determined. Receptor autoradiography and in situ hybridization revealed a reduction in striatal and cortical A(1) receptor density and cortical A(1) receptor mRNA, respectively, in antisense-treated brains but not in those treated with a mismatch oligonucleotide. There was no change in A(2) receptor binding. These data imply that the corticostriatal pathway synthesizes A(1) receptors and transports them to its terminals.
