Abstract

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a potent toxin used to selectively destroy dopaminergic neurons in the substantia nigra and induce parkinsonism. MPTP is metabolised to the 1-methyl-4-phenylpyridinium ion (MPP(+)) in glia, after which it enters the neuron via the dopamine transporter and results in elevated levels of oxidative stress. The mechanism through which MPP(+) causes cell death is thought to involve redox-active metals, particularly iron (Fe). This review will examine how cellular metal metabolism is altered following MPTP insult, and how this relates to metal dyshomeostasis in idiopathic Parkinson's disease. This includes both cell damage arising from increased metal concentration, and how metal-binding proteins respond to MPTP-induced neurotoxicity. Implications for using MPTP as a model for human Parkinson's disease will be discussed in terms of cell metallobiology.

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.
