Abstract

Filamentous tau inclusions in neurons and glia are neuropathological hallmarks of sporadic and familial tauopathies. Because tau gene mutations are pathogenic for the autosomal dominant tauopathy “frontotemporal dementia and parkinsonism linked to chromosome 17,” tau abnormalities are implicated directly in the onset and/or progression of disease. Although filamentous tau aggregates are acknowledged to play roles in degenerative mechanisms resulting in neuron loss, the contributions of glial tau pathology to neurodegeneration remain essentially unexplored. To begin to elucidate the role of glial pathology in tauopathies, we generated a transgenic (Tg) mouse model of astrocytic tau pathology by expressing the human tau protein driven by the glial fibrillary acidic protein (GFAP) promoter. Whereas endogenous tau was not detected in astrocytes of control mice, in GFAP/tau Tg mice there was robust astrocytic tau expression that was associated with a redistribution of the GFAP network. Subsequently, there was an age-dependent accumulation of tau pathology in astrocytes that was Gallyas and variably thioflavine S positive as observed in many tauopathies. The tau pathology in these Tg mice was abnormally phosphorylated, ubiquitinated, and filamentous, and the emergence of this pathology coincided with accumulation of insoluble tau protein. Furthermore, in regions with robust astrocytic tau pathology, there was mild blood- brain barrier disruption, induction of low-molecular-weight heat shock proteins, and focal neuron degeneration. Thus, these Tg mice recapitulate key features of astrocytic pathology observed in human tauopathies and demonstrate functional consequences of this pathology including neuron degeneration in the absence of neuronal tau inclusions.

  • Accumulation of tau in astrocytes alters astrocytic function, induces neuronal degeneration and promotes cell death through serial degenerative events such as BBB collapse and expression of low-molecular-weight heat shock proteins.

    “Accumulation of tau in astrocytes alters astrocytic function, induces neuronal degeneration and promotes cell death through a serial degenerative events, such as boosting blood-brain barrier (BBB) collapse, and inducing expression of heat shock proteins with low molecular weight [228, 434, 436, 437].”
  • Phosphorylation, fibrosis and asymmetric accumulation of tau in astrocytes increase with age in mice expressing P301L tau.

    “Phosphorylation, fibrosis and asymmetric accumulation of tau in astrocytes increased with age in mice expressing P301L tau [434].”
  • In mice expressing P301L human tau under an astrocyte-specific promoter, tau accumulation in astrocytes is followed by neuronal degeneration.

    “Finally, neurofilament staining revealed ballooned neurons and axonal degeneration in areas with abundant tau pathology [126].”

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.
