Abstract

Tauopathies are sporadic and genetic neurodegenerative diseases characterized by aggregation of the microtubule-associated protein Tau. Tau pathology occurs in over 20 phenotypically distinct neurodegenerative diseases, including Alzheimer disease and frontotemporal dementia. The molecular basis of this diversity among sporadic tauopathies is unknown, but distinct fibrillar wild-type (WT) Tau conformations could play a role. Using Fourier transform infrared spectroscopy, circular dichroism, and electron microscopy, we show that WT Tau fibrils and P301L/V337M Tau fibrils have distinct secondary structures, fragilities, and morphologies. Furthermore, P301L/V337M fibrillar seeds induce WT Tau monomer to form a novel fibrillar conformation, termed WT*, that is maintained over multiple seeding reactions. WT* has secondary structure, fragility, and morphology that are similar to P301L/V337M fibrils and distinct from WT fibrils. WT Tau is thus capable of conformational diversity that arises via templated conformation change, as has been described for amyloid beta, beta2-microglobulin, and prion proteins.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Exogenously supplied tau fibrils seed aggregation of transgenic human and endogenous mouse tau in mouse tauopathy models by enhancing nucleation, and these aggregates spread transsynaptically to remote connected brain regions.

    “Exogenously supplied fibrils will seed aggregation of transgenic human and endogenous mouse tau fibrils in mouse tauopathy models by enhancing nucleation of new fibrils. These aggregates then spread transsynaptically to remote anatomically connected brain regions inducing further seeding and aggregation”

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.
