Abstract

Type 2 diabetes (T2D) is an age-related disease. Although changes in function and proliferation of aged β cells resemble those preceding the development of diabetes, the contribution of β cell aging and senescence remains unclear. We generated a β cell senescence signature and found that insulin resistance accelerates β cell senescence leading to loss of function and cellular identity and worsening metabolic profile. Senolysis (removal of senescent cells), using either a transgenic INK-ATTAC model or oral ABT263, improved glucose metabolism and β cell function while decreasing expression of markers of aging, senescence, and senescence-associated secretory profile (SASP). Beneficial effects of senolysis were observed in an aging model as well as with insulin resistance induced both pharmacologically (S961) and physiologically (high-fat diet). Human senescent β cells also responded to senolysis, establishing the foundation for translation. These novel findings lay the framework to pursue senolysis of β cells as a preventive and alleviating strategy for T2D.

  • Mouse models of insulin resistance induced by high-fat diet and S961 show elevated SA-β-gal activity and expression of Cdkn1a, Cdkn2a and SASP factors Il1a, Il6, Tnf, Ccl3, Ccl4, Ccl5, Cxcl1 and Cxcl10.

    “Mouse models of insulin resistance induced by a high-fat diet and the insulin receptor antagonist S961 exhibit elevation of SA-β-gal activity, and expression of Cdkn1a, Cdkn2a and the SASP factors Il1a, Il6, Tnf, Ccl3, Ccl4, Ccl5, Cxcl1 and Cxcl10 (ref. 182).”

    From SenNet recommendations for detecting senescent cells in different tissues (2024) · cites this paper as [182]

    The Results section, “Insulin resistance accelerated the appearance of senescent β-cells” (page unavailable), reports increased β-gal-positive cells and aging and SASP gene-expression indices after both S961 treatment and high-fat diet. The Methods section defines those indices to include p21, p16, Il1a, Il6 and TNFα, but not Ccl3, Ccl4, Ccl5, Cxcl1 or Cxcl10; it also does not establish that every listed gene rose individually in both models.

  • Senescent cells themselves are critically involved in T1D and T2D, and the deletion of senescent beta cells prevents diabetes.

    “Concerning age-related diseases, senescent cells themselves are critically involved in T1D and T2D, and the deletion of senescent beta cells prevents diabetes (57, 298), indicating that even in T1D in which tissue-specific T cells are involved (299–301), local initiators originating from senescent beta cells play critical roles.”

    From IL-6 in inflammation, autoimmunity and cancer (2021) · cites this paper as [298]

    The Discussion (page unavailable) reports that deleting p16Ink4a-positive cells improved glucose homeostasis and β-cell function in mouse models of aging and insulin resistance, supporting a role for senescent β-cells in T2D-related dysfunction. It does not show that deletion prevents diabetes. For T1D, the Discussion describes senolysis as a possible application and cites Thompson et al. (2019) for evidence of senescent β-cells in a T1D mouse model; it does not establish a critical role in T1D. (LLM, conf=0.89)

  • Beta-cell senescence has a key role in the development of type 2 diabetes.

    “We have previously shown that β-cell senescence has a key role in the development of the disease.”
  • In mice, clearing senescent cells improves glucose responsiveness, cellular transcriptional identity and blood glucose levels.

    “in contrast, clearance of senescent cells improved glucose responsiveness, cellular transcriptional identity and blood glucose concentrations8.”

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.
