Abstract

The recent discovery of mitochondrial complex I deficiency in the substantia nigra of patients with idiopathic Parkinson's disease has provided new understanding into the possible mechanisms that may underlie this neurodegenerative disorder. The biochemical defect is identical to that induced in humans, primates and mice exposed to the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. We have studied mitochondrial respiratory chain function in various brain regions, in skeletal muscle and in blood platelets from patients with idiopathic Parkinson's disease and from matched controls. We provide evidence suggesting that the complex I deficiency in Parkinson's disease is limited to the brain and that this defect is specific for the substantia nigra. The tissue specificity of the complex I deficiency in Parkinson's disease and its localization to the substantia nigra support the proposition that complex I deficiency may be directly involved in the cause of dopaminergic cell death in Parkinson's disease. An understanding of the molecular basis of this biochemical defect will provide valuable insight into the cause of Parkinson's disease. Our findings of normal mitochondrial function in platelet homogenates suggests that this tissue cannot be used to develop a 'diagnostic test' for Parkinson's disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
