General aspects of neurodegeneration

Jellinger, K. A.·2003·Journal of Neural Transmission. Supplementa

Abstract

Neurodegenerative diseases are morphologically featured by progressive cell loss in specific vulnerable neuronal populations of the central nervous system, often associated with cytoskeletal protein aggregates forming intracytoplasmic and/or intranuclear inclusions in neurons and/or glial cells. Most neurodegenerative disorders are now classified either according to the hitherto known genetic mechanisms or to the major components of their cellular protein inclusions. The major basic processes inducing neurodegeneration are considered multifactorial ones caused by genetic, environmental, and endogenous factors. They include abnormal protein dynamics with defective protein degradation and aggregation, many of them related to the ubiquitin-proteasomal system, oxidative stress and free radical formation, impaired bioenergetics and mitochondrial dysfunctions, and "neuroinflammatory" processes. These mechanisms that are usually interrelated in complex vitious circles finally leading to programmed cell death cascades are briefly discussed with reference to their pathogenetic role in many, albeit diverse neurodegenerative diseases, like Alzheimer disease, synucleinopathies, tauopathies, and polyglutamine disorders. The impact of protein inclusions on cell dysfunction, activation or prevention of cell death cascades are discussed, but the molecular basis for the underlying disease mechanisms remains to be elucidated.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Neurodegenerative diseases, including Alzheimer's disease, are multifactorial, caused by multiple genetic, environmental, or endogenous factors, possibly operating simultaneously.

    “A strong argument in favor of complex pharmacology strategies for the treatment of complex neurodegenerative diseases is based on the fact that these diseases are multifactorial, that is, they are caused by multiple factors, being possibly genetic, environmental, endogenous, or even having more than one factor operating at the same time.21”

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.
