Adaptive acetylcholinesterase splicing patterns attenuate 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinsonism in mice.
Balanced dopaminergic cholinergic interactions are crucial for proper basal ganglia function. This is dramatically demonstrated by the worsening of Parkinson's disease symptoms following acetylcholinesterase (AChE) inhibition. Typically, in the brain, the synapse-anchored synaptic AChE (AChE-S) variant is prevalent whereas the soluble readthrough AChE (AChE-R) variant is induced in response to ...
متن کاملPoly(ADP-ribose) polymerase activation mediates 1-methyl-4-phenyl-1, 2,3,6-tetrahydropyridine (MPTP)-induced parkinsonism.
1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a neurotoxin that causes parkinsonism in humans and nonhuman animals, and its use has led to greater understanding of the pathogenesis of Parkinson's disease. However, its molecular targets have not been defined. We show that mice lacking the gene for poly(ADP-ribose) polymerase (PARP), which catalyzes the attachment of ADP ribose units fro...
متن کاملLocal cerebral metabolic effects of L-dopa therapy in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced parkinsonism in monkeys.
The quantitative 2-deoxy[14C]glucose autoradiographic method was used to map the distribution of alterations in local cerebral glucose utilization that accompanies clinically effective chronic L-dopa therapy of rhesus monkeys made parkinsonian by the administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). This pattern of changes was compared to the effects of a similar treatment ...
متن کاملRho kinase II interference by small hairpin RNA ameliorates 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced parkinsonism in mice
Novel therapeutic targets are required for the treatment of Parkinson's disease (PD). Previous studies suggest that the Rho/Rho‑associated, coiled‑coil‑containing protein kinases (ROCKs) signaling pathway may be a promising therapeutic target in PD. To elucidate the importance of ROCKII in the pathogenesis of dopaminergic (DA) neuron loss and to investigate the efficacy of ROCK inhibitors in PD...
متن کاملThe clinical syndrome of striatal dopamine deficiency. Parkinsonism induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).
Exposure to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) produces a syndrome that resembles Parkinson's disease. To compare the biochemical abnormalities produced by this compound in human beings with those occurring in Parkinson's disease, we examined biogenic amine metabolites in cerebrospinal fluid and urine from six patients with MPTP-induced parkinsonism and eight patients with Park...
