Abstract

We characterized beta-synuclein, the non-amyloidogenic homolog of alpha-synuclein, as an inhibitor of aggregation of alpha-synuclein, a molecule implicated in Parkinson's disease. For this, doubly transgenic mice expressing human (h) alpha- and beta-synuclein were generated. In doubly transgenic mice, beta-synuclein ameliorated motor deficits, neurodegenerative alterations, and neuronal alpha-synuclein accumulation seen in halpha-synuclein transgenic mice. Similarly, cell lines transfected with beta-synuclein were resistant to alpha-synuclein accumulation. halpha-synuclein was coimmunoprecipitated with hbeta-synuclein in the brains of doubly transgenic mice and in the double-transfected cell lines. Our results raise the possibility that beta-synuclein might be a natural negative regulator of alpha-synuclein aggregation and that a similar class of endogenous factors might regulate the aggregation state of other molecules involved in neurodegeneration. Such an anti-amyloidogenic property of beta-synuclein might also provide a novel strategy for the treatment of neurodegenerative disorders.

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.
