Abstract

Brain samples from 14 Parkinson's disease patients, 10 of whom developed motor complications (dyskinesias and/or wearing-off) on dopaminomimetic therapy, and 11 controls were analyzed. Striatal 3β-(4-125I-iodophenyl)tropane-2β-carboxylic acid isopropyl ester ([125I]RTI-121)-specific binding to dopamine transporter and concentration of dopamine were markedly decreased, but no association between level of denervation and development of motor complications was observed. The homovanillic acid/dopamine ratio of concentrations was higher in putamen of patients with wearing-off compared to those without. Striatal 35S-labeled t-butylbicyclophosphorothionate ([35S]TBPS) and [3H]flunitrazepam binding to GABAA receptors were unchanged in patients with Parkinsons disease, whereas [125I]CGP 64213 -specific binding to GABAB receptors was decreased in the putamen and external segment of the globus pallidus of parkinsonian patients compared with controls. [3H]Flunitrazepam binding was increased in the putamen of patients with wearing-off compared to those without. [35S]TBPS-specific binding was increased in the ventral internal globus pallidus of dyskinetic subjects. These data suggest altered dopamine metabolism and increased GABAA receptors in the putamen related to the pathophysiology of wearing-off. The present results also suggest that an up-regulation of GABAA receptors in the internal globus pallidus is linked to the pathogenesis of levodopa-induced dyskinesias.

<s0>Brain samples from 14 Parkinson's disease patients, 10 of whom developed motor complications (dyskinesias and/or wearing-off) on dopaminomimetic therapy, and 11 controls were analyzed. Striatal 3β-(4-
<sup>125</sup>
I-iodophenyl)tropane-2β-carboxylic acid isopropyl ester ([
<sup>125</sup>
I]RTI-121)-specific binding to dopamine transporter and concentration of dopamine were markedly decreased, but no association between level of denervation and development of motor complications was observed. The homovanillic acid/dopamine ratio of concentrations was higher in putamen of patients with wearing-off compared to those without. Striatal
<sup>35</sup>
S-labeled t-butylbicyclophosphorothionate ([
<sup>35</sup>
S]TBPS) and [
<sup>3</sup>
H]flunitrazepam binding to GABA
<sub>A</sub>
receptors were unchanged in patients with Parkinsons disease, whereas [
<sup>125</sup>
I]CGP 64213 -specific binding to GABA
<sub>B</sub>
receptors was decreased in the putamen and external segment of the globus pallidus of parkinsonian patients compared with controls. [
<sup>3</sup>
H]Flunitrazepam binding was increased in the putamen of patients with wearing-off compared to those without. [
<sup>35</sup>
S]TBPS-specific binding was increased in the ventral internal globus pallidus of dyskinetic subjects. These data suggest altered dopamine metabolism and increased GABA
<sub>A</sub>
receptors in the putamen related to the pathophysiology of wearing-off. The present results also suggest that an up-regulation of GABA
<sub>A</sub>
receptors in the internal globus pallidus is linked to the pathogenesis of levodopa-induced dyskinesias.</s0>
