Abstract

We have exploited whole brain microscopy to map the progressive deposition of hyperphosphorylated tau in intact, cleared mouse brain. We found that the three-dimensional spreading pattern of hyperphosphorylated tau in the brain of an aging Tau.P301L mouse model did not resemble that observed in AD patients. Injection of synthetic or patient-derived tau fibrils in the CA1 region resulted in a more faithful spreading pattern. Atlas-guided volumetric analysis showed a connectome-dependent spreading from the injection site and also revealed hyperphosphorylated tau deposits beyond the direct anatomical connections. In fibril-injected brains, we also detected a persistent subpopulation of rod-like and swollen microglia. Furthermore, we showed that the hyperphosphorylated tau load could be reduced by intracranial co-administration of, and to a lesser extent, by repeated systemic dosing with an antibody targeting the microtubule-binding domain of tau. Thus, the combination of targeted seeding and in toto staging of tau pathology allowed assessing regional vulnerability in a comprehensive manner, and holds potential as a preclinical drug validation tool.

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.
