Abstract

A pathway from the natively unfolded microtubule-associated protein Tau to a highly structured amyloid fibril underlies human Tauopathies. This ordered assembly causes disease and represents the gain of toxic function. In recent years, evidence has accumulated to suggest that Tau inclusions form first in a small number of brain cells, from where they propagate to other regions, resulting in neurodegeneration and disease. Propagation of pathology is often called prion-like, which refers to the capacity of an assembled protein to induce the same abnormal conformation in a protein of the same kind, initiating a self-amplifying cascade. In addition, prion-like encompasses the release of protein aggregates from brain cells and their uptake by neighboring cells. In mice, the intracerebral injection of Tau inclusions induces the ordered assembly of monomeric Tau, followed by its spreading to distant brain regions. Conformational differences between Tau aggregates from transgenic mouse brain and in vitro assembled recombinant protein account for the greater seeding potency of brain aggregates. Short fibrils constitute the major species of seed-competent Tau in the brains of transgenic mice. The existence of multiple human Tauopathies with distinct fibril morphologies has led to the suggestion that different molecular conformers (or strains) of aggregated Tau exist.

  • Pathological tau disrupts synaptic integrity and neuronal connectivity, driving neurodegeneration and cognitive decline.

    “Pathological tau, characterized by hyperphosphorylation and aggregation into neurofibrillary tangles, disrupts synaptic integrity and neuronal connectivity, driving neurodegeneration and cognitive decline.”

    From Protective mechanisms against Alzheimer's disease in APOE3‐Christchurch homozygous astrocytes (2025) · cites this paper as [14]

    The Introduction (page not provided) identifies tau dysfunction as a cause of neurodegeneration, and Tau Toxicity reports synaptic-protein missorting and nerve-cell dysfunction in a mouse model. But Propagation of Tau Aggregates describes synaptic contacts and neuronal connectivity as routes for tau spread, not as structures that tau disrupts. The cited passages also do not establish the proposed chain from disrupted connectivity to cognitive decline. (LLM, conf=0.84)

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.
