Nociceptin/orphanin FQ receptor blockade attenuates MPTP-induced parkinsonism.
Endogenous nociceptin/orphanin FQ (N/OFQ) inhibits the activity of dopamine neurons in the substantia nigra and affects motor behavior. In this study we investigated whether a N/OFQ receptor (NOP) antagonist, J-113397, can modify movement in naive mice and nonhuman primates and attenuate motor deficits in MPTP-treated parkinsonian animals. J-113397 facilitated motor activity in naïve mice at lo...
متن کاملRopinirole Implants Reverse MPTP-Induced Parkinsonism in Rhesus Monkeys
Purpose: We compared efficacy and side effects of ropinirole implants with oral ropinirole in parkinsonian monkeys. Methods: Twenty monkeys received injections of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-hydrochloride (MPTP) to render them parkinsonian. Monkeys were then placed into 3 groups based upon clinical rating scores (CRS). Group 1 received oral ropinirole and placebo implants. Grou...
متن کاملRest tremor in rhesus monkeys with MPTP-induced parkinsonism.
Rest tremor (RTr) is a typical feature of Parkinson's diseases (PD). Animal models of PD presenting with RTr are indispensable for understanding the pathophysiology of human RTr and the development of new therapeutic agents. In this report we studied the occurrence of tremor on rhesus monkeys rendered parkinsonian by an intracarotid (ICA) infusion followed by 2-4 iv. doses of n-methyl-4-phenyl-...
متن کاملLack of major olfactory dysfunction in MPTP-induced parkinsonism.
The olfactory function of 6 patients whose parkinsonism was the result of intravenous administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was compared to that of 12 age-matched patients with idiopathic Parkinson's disease (PD) and 10 age-matched normal control subjects. Unlike their PD counterparts, the olfactory test scores of patients with MPTP-induced parkinsonism did not d...
متن کاملThe primate subthalamic nucleus. II. Neuronal activity in the MPTP model of parkinsonism.
1. The neuronal mechanisms underlying the major motor signs of Parkinson's disease were studied in the basal ganglia of parkinsonian monkeys. Three African green monkeys were systemically treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) until parkinsonian signs, including akinesia, rigidity, and a prominent 4- to 8-Hz tremor, appeared. The activity of neurons in the subthalamic ...
