Abstract

Autophagy, an essential cellular process that mediates degradation of proteins and organelles in lysosomes, has been tightly linked to cellular quality control for its role as part of the proteostasis network. The current interest in identifying the cellular and molecular determinants of aging, has highlighted the important contribution of malfunctioning of autophagy with age to the loss of proteostasis that characterizes all old organisms. However, the diversity of cellular functions of the different types of autophagy and the often reciprocal interactions of autophagy with other determinants of aging, is placing autophagy at the center of the aging process. In this work, we summarize evidence for the contribution of autophagy to health- and lifespan and provide examples of the bidirectional interplay between autophagic pathways and several of the so-called hallmarks of aging. This central role of autophagy in aging, and the dependence on autophagy of many geroprotective interventions, has motivated a search for direct modulators of autophagy that could be used to slow aging and extend healthspan. Here, we review some of those ongoing therapeutic efforts and comment on the potential of targeting autophagy in aging.

  • This led to the identification of some of the earliest disease-associated genes, including APP, PS1 and PS2 in AD, SNCA and LRRK2 in PD and MAPT and GRN in FTD.

    “This subsequently led to the identification of some of the earliest disease-associated genes, including APP, PS1 and PS2 in AD, SNCA and LRRK2 in PD and MAPT and GRN in FTD.79–87”

    From The lysosome and proteostatic stress at the intersection of pediatric neurological disorders and adult neurodegenerative diseases (2025) · cites this paper as [84]

    The passages from “Autophagy activators as novel geroprotectors” discuss tauopathy models and autophagy treatments, not the discovery of disease-associated genes. Searches for the listed genes and for early genetic discoveries in AD, PD, and FTD found no passage in our copy that addresses the claim; a References entry mentions APP/PS1 mice but not gene identification. No page numbers were provided for these passages. (LLM, conf=0.74)

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.
