In monkeys rendered parkinsonian with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), expression of the dopamine D3 receptor was decreased. However, levodopa-induced dyskinesia (LID), similar to the debilitating and pharmacoresistant involuntary movements elicited after long-term treatment with levodopa in patients with Parkinson disease (PD), was(More)
Involuntary movements, or dyskinesia, represent a debilitating complication of levodopa therapy for Parkinson's disease. Taking advantage of a monkey brain bank constituted to study the pathophysiology of levodopa-induced dyskinesia, we here report the changes affecting D1, D2 and D3 dopamine receptors within the striatum of four experimental groups of(More)
The calcium-sensing receptor (CaSR) is a member of a growing family of heptahelical receptors with an unusually large extracellular domain. To further delineate its functions in neurons and glia, we have investigated the expression pattern of CaSR transcripts in the postnatal and adult rat brain, spinal cord and dorsal root ganglia by in situ hybridization.(More)
