Abstract

The major human neurodegenerative diseases are characterised by ubiquitin-positive intraneuronal inclusions, however the precise nature of the ubiquitin modifications in these structures is unclear. Using a monoclonal antibody specific for Lys63-linked polyubiquitin we have performed the first immunohistochemical analysis of linkage-specific ubiquitination in vivo associated with neurodegeneration. Immunoreactivity was detected within the pathological lesions of Alzheimer's, Huntington's and Parkinson's disease brains, although staining of Lewy bodies in the substantia nigra in Parkinson's disease was rare, indicating a selective involvement of Lys63-linked polyubiquitin in inclusion biogenesis in this disorder. Immunoreactivity was also a feature in neurons of proteasome-depleted mice, suggesting a proteasomal contribution to the degradation of Lys63-linked polyubiquitinated proteins in vivo.

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.
