To investigate the impact of strain and sex in the l-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) animal model of Parkinson's disease, C57BL/6 and BALB/c mice were treated with either systemic MPTP-HCl (4 x 15 mg/kg) or saline and were examined in a number of behavioral tests. Furthermore, neostriatal and ventral striatal monoamine contents were(More)
In mice, the systemical or intracranial application of the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) can lead to severe damage to the nigrostriatal dopaminergic system. This can result in a variety of symptoms concerning motor control resembling those in human Parkinson's disease, such as akinesia, rigidity, tremor, gait and posture(More)
The neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is capable of producing a syndrome in mice which shares major characteristics with human Parkinson's disease. There is evidence for a genetic influence on the degree of damage exerted by MPTP, since different strains of mice can dramatically differ in their response to MPTP. We produced(More)
The neurotoxin MPTP can damage dopamine systems in the brains of rodents, cats, or monkeys, and is therefore widely used to model degenerative processes that underlie human Parkinson’s disease. Here, we investigated the relationships between behavioral and neurochemical effects of systemic MPTP treatment in C57BL/6 and Balb/c mice. Initially, different(More)
Parkinson's disease (PD) is a neurodegenerative disorder characterized by the dysfunction of the nigrostriatal dopaminergic pathway. Although its etiology is not yet fully understood, an interaction of genetic predisposition and environmental factors is frequently discussed. The neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) can evoke(More)
The neurotoxicity induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is one of the most valuable available models for investigating critical aspects of human Parkinson's disease. In order to analyze the relevance of pigmentation for MPTP sensitivity, we compared C57Bl/6 wild-type mice with the albino mutant C57Bl/6J-Tyr(c-2J) of the same strain.(More)
