Dyskinesia, a major complication of treatment of Parkinson’s disease (PD), involves two phases: induction, which is responsible for dyskinesia onset, and expression, which underlies its clinical manifestation. The unique cellular and regional distribution of adenosine receptors in basal ganglia areas that are richly innervated by dopamine, and their antagonistic role towards dopamine receptor stimulation, have positioned receptor antagonists as an attractive nondopaminergic target to improve the motor deficits that characterize PD. In this paper, we describe the biochemical characteristics of receptors and the effects of adenosine antagonists in rodent and primate models of PD on L-DOPA-induced dyskinesia, together with relevant …
