Abstract

A growing number of PSEN1 mutations have been associated with dementia with Lewy bodies and familial Alzheimer's disease with concomitant α-synuclein pathology. The objective of this study was to determine if PSEN1 plays a direct role in the development of α-synuclein pathology in these diseases. Using mass spectrometry, immunoelectron microscopy and fluorescence lifetime image microscopy based on Forster resonance energy transfer (FLIM-FRET) we identified α-synuclein as a novel interactor of PSEN1 in wild-type mouse brain tissue. The interaction of α-synuclein with PSEN1 was detected in post-mortem brain tissue from cognitively normal cases and was significantly increased in tissue from cases with dementia with Lewy bodies and familial Alzheimer's disease associated with known PSEN1 mutations. We confirmed an increased interaction of PSEN1 and α-synuclein in cell lines expressing well characterized familial Alzheimer's disease PSEN1 mutations, L166P and delta exon 9, and demonstrated that PSEN1 mutations associate with increased membrane association and accumulation of α-synuclein. Our data provides evidence of a molecular interaction of PSEN1 and α-synuclein that may explain the clinical and pathophysiological overlap seen in synucleinopathies, including Parkinson's disease, dementia with Lewy bodies, and some forms of Alzheimer's disease.

  • Winslow and colleagues described a novel molecular interaction between PS1 and αSyn.

    “A direct involvement of αSyn in the production of Aβ (Fig. 2) in humans could be suggested by results from Winslow and colleagues who described a novel molecular interaction between presenilin 1 (PS1), an important player in the proteolytic processing of the APP to yield Aβ [200], and αSyn [201].”

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.
