Abstract

Environmental and genetic factors that contribute to the pathogenesis of Parkinson's disease are discussed. Mutations in the α‐synuclein (α SYN ) gene are associated with rare cases of autosomal‐dominant Parkinson's disease. We have analysed the dopaminergic system in transgenic mouse lines that expressed mutant [A30P]αSYN under the control of a neurone‐specific Thy‐1 or a tyrosine hydroxylase (TH) promoter. The latter mice showed somal and neuritic accumulation of transgenic [A30P]αSYN in TH‐positive neurones in the substantia nigra. However, there was no difference in the number of TH‐positive neurones in the substantia nigra and the concentrations of catecholamines in the striatum between these transgenic mice and non‐transgenic littermates. To investigate whether forced expression of [A30P]αSYN increased the sensitivity to putative environmental factors we subjected transgenic mice to a chronic 1‐methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine (MPTP) regimen. The MPTP‐induced decrease in the number of TH‐positive neurones in the substantia nigra and the concentrations of catecholamines in the striatum did not differ in any of the [A30P]α SYN transgenic mouse lines compared with wild‐type controls. These results suggest that mutations and forced expression of αSYN are not likely to increase the susceptibility to environmental toxins in vivo.

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.
