| heal.abstract | Long-term levodopa replacement therapy in Parkinson's disease is confounded by abnormal involuntary movements, known as levodopa induced dyskinesia (LID). Dysfunctional glutamatergic neurotransmission has been implicated in the pathogenesis of LID making metabotropic and ionotropic glutamate receptors attractive novel therapeutic targets. The objective of the present study was to investigate the antidyskinetic site of action of different glutamate receptor antagonists in the brain. For that purpose, metabotropic glutamate subtype 5 (3-((2-Methyl-1,3-thiazol-4-yl)ethynyl)pyridine hydrochloride, MTEP), NMDA NR2B selective ((aR,bS)-a-(4-Hydroxyphenyl)-b-methyl-4-(phenylmethyl)-1-piperidinepropanol maleate, Ro 25-6981) and AMPA (2,3-Dioxo-6-nitro-1,2,3,4-tetrahydrobenzo[f]quinoxaline-7-sulfonamide disodium salt, NBQX) receptor antagonists or saline were administered by intracerebral infusion in the caudate-putamen (CPu), the substantia nigra zona reticulata (SNr) or the subthalamic nucleus (STN) of 6-hydroxydopamine-lesioned rats exhibiting LID. Dyskinesia was assessed with the modified version of the rat Abnormal Involuntary Movements scale (AIMS). Ro 25-6981 and to a lesser extent NBQX improved dyskinesia (82% and 19% reduction in AIM score respectively) after infusion in the caudate-putamen. None of the three drugs managed to noticeably reduce AIM score after infusion in the SNr. MTEP was the only drug that produced a reduction in AIM score (48%) when infused in STN. In conclusion, while the striatum proved important in the antidyskinetic action of NMDA and AMPA receptor antagonists, the results of this study highlight also the importance of the metabotropic glutamate receptors that reside in the STN as therapeutic targets in the treatment of LID. | en |
