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 non-human primates: normal, parkinsonian,
parkinsonian treated with levodopa without or with dyskinesia. We also report the
possible role of arrestin and G protein-coupled receptor kinases.
