Degradation of tau protein by autophagy and proteasomal pathways

Wang, Yipeng, Mandelkow, Eckhard·2012·Biochemical Society Transactions

Abstract

Tau aggregates are present in several neurodegenerative diseases and correlate with the severity of memory deficit in AD (Alzheimer's disease). However, the triggers of tau aggregation and tau-induced neurodegeneration are still elusive. The impairment of protein-degradation systems might play a role in such processes, as these pathways normally keep tau levels at a low level which may prevent aggregation. Some proteases can process tau and thus contribute to tau aggregation by generating amyloidogenic fragments, but the complete clearance of tau mainly relies on the UPS (ubiquitin–proteasome system) and the ALS (autophagy–lysosome system). In the present paper, we focus on the regulation of the degradation of tau by the UPS and ALS and its relation to tau aggregation. We anticipate that stimulation of these two protein-degradation systems might be a potential therapeutic strategy for AD and other tauopathies.

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?

  • Because tau is a target of autophagy, deficiencies in processing could lead to increased levels of intracellular tau, including misfolded, damaged or aggregated protein.

    “As tau is a target of autophagy80, any deficiencies in processing could lead to increased levels of intracellular tau, including misfolded, damaged or aggregated protein.”

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.
