Abstract

Ubiquitin-positive, tau- and α-synuclein–negative inclusions are hallmarks of frontotemporal lobar degeneration with ubiquitin-positive inclusions and amyotrophic lateral sclerosis. Although the identity of the ubiquitinated protein specific to either disorder was unknown, we showed that TDP-43 is the major disease protein in both disorders. Pathologic TDP-43 was hyper-phosphorylated, ubiquitinated, and cleaved to generate C-terminal fragments and was recovered only from affected central nervous system regions, including hippocampus, neocortex, and spinal cord. TDP-43 represents the common pathologic substrate linking these neurodegenerative disorders.

  • Hyperphosphorylated and ubiquitinated TDP-43 cytoplasmic inclusions are the most common (about 97%) pathological hallmark of ALS.

    “In 2006, hyperphosphorylated and ubiquitinated TDP-43 (encoded by TARDBP) cytoplasmic inclusions were identified as the most common (at about 97%) pathological hallmark of ALS.79”

  • Degenerating motor neurons in ALS patients commonly display cytoplasmic aggregates containing the DNA/RNA-binding protein TDP-43.

    “Degenerating motor neurons in ALS patients commonly display cytoplasmic aggregates containing the DNA/RNA-binding protein TDP-43 (Neumann et al. 2006).”
  • Cytoplasmic TDP43 mislocalization and aggregation are pathological hallmarks of ALS.

    “Cytoplasmic TDP43 mislocalization and aggregation are pathological hallmarks of amyotrophic lateral sclerosis (ALS).”
  • TDP-43 inclusions are observed in more than 95% of ALS, supporting that FTLD-TDP and ALS are part of a clinicopathological continuum.

    “TDP‐43 inclusions are also observed in > 95% of ALS, 22 supporting the notion that FTLD‐TDP and ALS are part of a clinicopathological continuum.”
  • The scarcity of pathologically characterized samples has prompted efforts to enrich cohorts with FTD syndromes highly correlated with a specific underlying neuropathology and/or to jointly analyze data from combined cohorts of sporadic and familial cases with the same neuropathology background.

    “The scarcity of these samples has prompted efforts to enrich cohorts with FTD syndromes that are highly correlated with a specific underlying neuropathology (e.g., FTD‐ALS for FTLD‐TDP 22 or PSP and CBS for FTLD‐tau 119 , 120 ) and/or to jointly analyze data from both combined cohorts of sporadic and familial cases with the same neuropathology background.”

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.
