The Role of the Subthalamic Nucleus in L-DOPA Induced Dyskinesia in 6-Hydroxydopamine Lesioned Rats
L-DOPA is the most effective treatment for Parkinson's disease (PD), but prolonged use leads to disabling motor complications including dyskinesia. Strong evidence supports a role of the subthalamic nucleus (STN) in the pathophysiology of PD whereas its role in dyskinesia is a matter of controversy. Here, we investigated the involvement of STN in dyskinesia, using single-unit extracellular reco...
متن کاملTargeting β-arrestin2 in the treatment of L-DOPA-induced dyskinesia in Parkinson's disease.
Parkinson's disease (PD) is characterized by severe locomotor deficits and is commonly treated with the dopamine (DA) precursor l-3,4-dihydroxyphenylalanine (L-DOPA), but its prolonged use causes dyskinesias referred to as L-DOPA-induced dyskinesias (LIDs). Recent studies in animal models of PD have suggested that dyskinesias are associated with the overactivation of G protein-mediated signalin...
متن کاملTargeting the D1-N-methyl-d-aspartate receptor complex reduces l-dopa-induced dyskinesia in 6-hydroxydopamine-lesioned Parkinson’s rats
L-3,4-dihydroxyphenylalanine (L-dopa) remains the most effective therapy for Parkinson's disease (PD), but its long-term administration is associated with the development of debilitating motor complications known as L-dopa-induced dyskinesia (LID). Enhanced function of dopamine D1 receptor (D1R) and N-methyl-D-aspartate receptor (NMDAR) is believed to participate in the pathogenesis of LID. Giv...
متن کاملLevodopa/benserazide microsphere (LBM) prevents L-dopa induced dyskinesia by inactivation of the DR1/PKA/P-tau pathway in 6-OHDA-lesioned Parkinson's rats
L-3, 4-dihydroxyphenylalanine (L-dopa) is the gold standard for symptomatic treatment of Parkinson's disease (PD), but long-term therapy is associated with the emergence of L-dopa-induced dyskinesia (LID). In the present study, L-dopa and benserazide were loaded by poly (lactic-co-glycolic acid) microspheres (LBM), which can release levodopa and benserazide in a sustained manner in order to con...
متن کاملUnilateral nigrostriatal 6-hydroxydopamine lesions in mice II: predicting l-DOPA-induced dyskinesia.
In the 6-hydroxydopamine (6-OHDA) lesioned rodent the location of the lesion produces significantly different behavioural phenotypes, responses to the dopamine precursor l-3,4-dihydroxyphenylalanine (l-DOPA) and neuropathology. Lesion extent is commonly determined by a series of motor tests, but whether any of these tests have a relationship to the development and predictability of dyskinesia i...
