Abstract

In the prion diseases, extensive reactive gliosis is often found to be out of proportion to the degree of apparent neuronal damage. To evaluate the role of astrocytic gliosis in experimental scrapie of the mouse, we inoculated mice deficient in apolipoprotein E (apoE) or the glial fibrillary acidic protein (GFAP) with mouse prions. The expression of both apoE and GFAP in astrocytes increases as part of the reactive gliosis that accompanies scrapie. Null mice deficient in either apoE or GFAP inoculated with prions exhibited incubation times indistinguishable from untargeted control mice. The level of PrPSc and its regional deposition in the brains of ill mice deficient in either protein were also similar to control mice. Our findings demonstrate that neither apoE nor GFAP participates in the pathogenesis of the disease or in the production of PrPSc.

Claims other papers make about this one

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

  • Both ApoE and TREM2 are upregulated in prion disease and affect the expression of pro-inflammatory proteins during the disease course in murine models, but their depletion did not change survival times.

    “Both proteins are upregulated in prion disease and affect the expression of pro-inflammatory proteins during the disease course in murine models. However, their depletion did not change survival times [102,103,104].”

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.
