Abstract

Aging is the major predictor for developing multiple neurodegenerative diseases, including Alzheimer's disease (AD) other dementias, and Parkinson's disease (PD). Senescent cells, which can drive aging phenotypes, accumulate at etiological sites of many age-related chronic diseases. These cells are resistant to apoptosis and can cause local and systemic dysfunction. Decreasing senescent cell abundance using senolytic drugs, agents that selectively target these cells, alleviates neurodegenerative diseases in preclinical models. In this review, we consider roles of senescent cells in neurodegenerative diseases and potential implications of senolytic agents as an innovative treatment.

  • Aging processes can be accentuated at etiologic sites of multiple acute and chronic diseases, including in children.

    “Aging progresses throughout the lifespan can be accentuated at etiologic sites of multiple acute and chronic diseases, including in children6,8–12.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [8]

    The Introduction links cellular senescence to several chronic diseases, and the Brain tumors section says chemoradiation can induce senescence with damaging effects in pediatric patients (page numbers unavailable). The paper also discusses senescence after stroke. These passages support examples of disease- and treatment-associated senescence, but not the broader claim that aging processes are accentuated at the etiologic sites of multiple acute and chronic diseases, including in children. (LLM, conf=0.82)

  • The introduction argues that senescent cells and their SASP products contribute to deficits in cognition and mobility.

    “Recent evidence suggests that the accumulation of senescent cells, which can release a variety of pro-inflammatory, apoptotic, and toxic by-products, called the senescence-associated secretory phenotype (SASP), is one of the drivers of deficits in both cognition11, 12, 13, 14, 15, 16 and mobility.7,17, 18, 19, 20, 21, 22”

    From A pilot study of senolytics to improve cognition and mobility in older adults at risk for Alzheimer's disease (2025) · cites this paper as [14]

    Experimental — accuracy not yet measured
  • Microglia and astrocytes can acquire a senescent phenotype, promoting diffusion of the senescence-associated secretory phenotype and conversion of healthy cells to senescence.

    “Microglia and astrocytes can acquire a senescent phenotype themselves (28, 31, 32), promoting further diffusion of the SASP and the conversion of healthy cells to the senescent phenotype.”
  • The burden of senescent cells in the brain increases with advanced age and neurodegenerative diseases and occurs across neurons, microglia, astrocytes, oligodendrocyte precursor cells, and endothelial cells.

    “The burden of senescent cells in the brain increases with advanced chronological age and neurodegenerative diseases, and occurs across cell types including neurons, microglia, astrocytes, oligodendrocyte precursor cells, and endothelial cells (28–32).”
  • Preclinical research provides strong proof-of-concept that tau-induced cellular senescence may be a therapeutic target for Alzheimer's disease.

    “Collectively, preclinical research has provided strong proof-of-concept data that tau-induced cellular senescence may be a novel therapeutic target for AD (29, 32).”

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.
