Hsp70 Reduces α-Synuclein Aggregation and Toxicity
Open accessAbstract
Aggregation and cytotoxicity of misfolded alpha-synuclein is postulated to be crucial in the disease process of neurodegenerative disorders such as Parkinson's disease and DLB (dementia with Lewy bodies). In this study, we detected misfolded and aggregated alpha-synuclein in a Triton X-100 insoluble fraction as well as a high molecular weight product by gel electrophoresis of temporal neocortex from DLB patients but not from controls. We also found similar Triton X-100 insoluble forms of alpha-synuclein in an alpha-synuclein transgenic mouse model and in an in vitro model of alpha-synuclein aggregation. Introducing the molecular chaperone Hsp70 into the in vivo model by breeding alpha-synuclein transgenic mice with Hsp70-overexpressing mice led to a significant reduction in both the high molecular weight and detergent-insoluble alpha-synuclein species. Concomitantly, we found that Hsp70 overexpression in vitro similarly reduced detergent-insoluble alpha-synuclein species and protected cells from alpha-synuclein-induced cellular toxicity. Taken together, these data demonstrate that the molecular chaperone Hsp70 can reduce the amount of misfolded, aggregated alpha-synuclein species in vivo and in vitro and protect it from alpha-synuclein-dependent toxicity.

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.
