Abstract

Chronic inflammation is associated with aging and plays a causative role in several age-related diseases such as cancer, atherosclerosis and osteoarthritis. The source of this chronic inflammation is often attributed to the progressive activation of immune cells over time. However, recent studies have shown that the process of cellular senescence, a tumor suppressive stress response that is also associated with aging, entails a striking increase in the secretion of pro-inflammatory proteins and might be an important additional contributor to chronic inflammation. Here, we list the secreted factors that make up the pro-inflammatory phenotype of senescent cells and describe the impact of these factors on tissue homeostasis. We also summarize the cellular pathways/processes that are known to regulate this phenotype – namely, the DNA damage response, microRNAs, key transcription factors and kinases and chromatin remodeling.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The SASP includes proteins that can help senescent cells evade immune recognition and clearance.

    “Finally, the SASP also includes proteins that can help senescent cells evade immune recognition and clearance (92, 93).”

    From Aging, Cellular Senescence, and Cancer (2013) · cites this paper as [93]

    The “Multiple roles of the SASP” section says the SASP might signal the immune system to clear senescent cells. It also describes SASP-associated cytokines and enzymes promoting clearance in mouse models. The cited paper thus makes the contrary point, rather than identifying proteins that help senescent cells evade recognition or clearance. Page numbers were not available in our copy.

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Specialized SASP chemokines attract distinct immune cell subsets, including NK cells, neutrophils, dendritic cells, monocytes/macrophages, B cells and T cells.

    “Specialized SASP chemokines are able to attract distinct subsets of immune cells, including NK cells, neutrophils, dendritic cells, monocytes/macrophages, B cells and T cells75,151,152.”

    From Cellular senescence in ageing: from mechanisms to therapeutic opportunities (2021) · cites this paper as [152]

    The sections “Senescent cells as a source of chronic inflammation” and “Multiple roles of the SASP” say that the SASP includes chemokines and can stimulate immune clearance, including clearance by NK cells. “Chronic inflammation might propel basic aging processes” also describes senescent-cell cytokines as attractors of innate immune cells. The paper does not establish that specialized SASP chemokines attract each of the other listed subsets—neutrophils, dendritic cells, monocytes/macrophages, B cells and T cells. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Prolonged secretion of SASP factors, such as IL-1β and MMP, could drive cancer development.

    “Therefore, prolonged secretion of SASP factors, such as interleukin (IL)‐1β and MMP, could drive cancer development.44, 45, 46”

    From Cellular senescence and senescence-associated secretory phenotype via the cGAS-STING signaling pathway in cancer (2020) · cites this paper as [44]

    The ‘Senescent cells as a source of chronic inflammation’ section identifies MMP-1, MMP-3 and IL-1 as secreted SASP factors and reports that senescent cells can promote the growth and invasion of malignant or premalignant cells. It does not identify IL-1β specifically or establish that its prolonged secretion drives cancer development; its discussion of IL-1α instead concerns regulation of the SASP. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The secretion of these inflammatory proteins by senescent cells is predicted to cause chronic inflammation locally and possibly systemically.

    “The secretion of these and similar proteins by senescent cells is predicted to cause chronic inflammation, at least locally and possibly systemically (91–93, 107).”

    From Aging, Cellular Senescence, and Cancer (2013) · cites this paper as [93]

  • Many components of the senescence-associated secretory phenotype promote inflammation, either directly or indirectly.

    “many SASP components directly or indirectly promote inflammation (59, 92, 93, 107, 108).”

    From Aging, Cellular Senescence, and Cancer (2013) · cites this paper as [93]

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.
