Abstract

Autophagy is the major cellular pathway to degrade dysfunctional organelles and protein aggregates. Autophagy is particularly important in neurons, which are terminally differentiated cells that must last the lifetime of the organism. There are both constitutive and stress-induced pathways for autophagy in neurons, which catalyze the turnover of aged or damaged mitochondria, endoplasmic reticulum, other cellular organelles, and aggregated proteins. These pathways are required in neurodevelopment as well as in the maintenance of neuronal homeostasis. Here we review the core components of the pathway for autophagosome biogenesis, as well as the cell biology of bulk and selective autophagy in neurons. Finally, we discuss the role of autophagy in neuronal development, homeostasis, and aging and the links between deficits in autophagy and neurodegeneration.

  • Reducing tau acetylation restores its degradation through CMA.

    “Reducing tau acetylation restores its degradation through CMA (Figure 5).90,147”

    From The lysosome and proteostatic stress at the intersection of pediatric neurological disorders and adult neurodegenerative diseases (2025) · cites this paper as [147]

    The Introduction (page not available) mentions chaperone-mediated autophagy as a neuronal protein-degradation pathway, but does not discuss tau. Searches for tau, acetylation, and CMA found no passage stating that reducing tau acetylation restores its degradation through CMA. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Tau acetylation impairs tau clearance through CMA by reducing entry into the lysosome and proteolysis by the lysosome.

    “Tau acetylation contributes to tau pathology via multiple potential mechanisms: promoting tau fibrillation146 and impairing tau clearance through CMA both by reducing entry into the lysosome and proteolysis by the lysosome.147”

    From The lysosome and proteostatic stress at the intersection of pediatric neurological disorders and adult neurodegenerative diseases (2025) · cites this paper as [147]

    The Introduction describes chaperone-mediated autophagy as a neuronal protein-degradation pathway, and “Autophagy in Disease” says defects in that pathway may contribute to neurodegeneration. Neither passage addresses tau acetylation, tau entry into lysosomes, or its lysosomal proteolysis; searches for those terms found no supporting passage in our copy. Page numbers were not available. (LLM, conf=0.75)

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.
