Abstract

Cellular senescence is characterized by stable cell-cycle arrest and a secretory program that modulates the tissue microenvironment1,2. Physiologically, senescence serves as a tumour-suppressive mechanism that prevents the expansion of premalignant cells3,4 and has a beneficial role in wound-healing responses5,6. Pathologically, the aberrant accumulation of senescent cells generates an inflammatory milieu that leads to chronic tissue damage and contributes to diseases such as liver and lung fibrosis, atherosclerosis, diabetes and osteoarthritis1,7. Accordingly, eliminating senescent cells from damaged tissues in mice ameliorates the symptoms of these pathologies and even promotes longevity1,2,8–10. Here we test the therapeutic concept that chimeric antigen receptor (CAR) T cells that target senescent cells can be effective senolytic agents. We identify the urokinase-type plasminogen activator receptor (uPAR)11 as a cell-surface protein that is broadly induced during senescence and show that uPAR-specific CAR T cells efficiently ablate senescent cells in vitro and in vivo. CAR T cells that target uPAR extend the survival of mice with lung adenocarcinoma that are treated with a senescence-inducing combination of drugs, and restore tissue homeostasis in mice in which liver fibrosis is induced chemically or by diet. These results establish the therapeutic potential of senolytic CAR T cells for senescence-associated diseases. Chimeric antigen receptor (CAR) T cells targeting uPAR, a cell-surface protein that is upregulated on senescent cells, eliminate senescent cells in vitro and in vivo and reduce liver fibrosis in mice.

  • Certain cell surface proteins are more highly expressed by senescent cells than most other cell types, prompting development of CAR T cells, vaccines, and antibody-drug conjugates targeting these markers.

    “Certain cell surface proteins tend to be more highly expressed by senescent cells than most other cell types, which prompted development of engineered chimeric antigen receptor (CAR) T cells, vaccines and antibody–drug conjugates targeting these cell surface markers.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [96]

    The paper’s Abstract reports that surface proteins are upregulated in senescent cells and that the authors developed uPAR-targeting CAR T cells. It does not report the development of vaccines or antibody–drug conjugates targeting those markers, so those parts of the attributed claim are unsupported. Page numbers are unavailable in our copy. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • These immune-targeting approaches eliminate senescent cells, but in some cases also affect activated macrophages and other non-senescent cell types.

    “Each of these approaches eliminates senescent cells, although in some cases, activated macrophages and other non-senescent cell types are also affected96–99.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [96]

    The paper reports that uPAR-directed CAR T cells eliminate senescent cells and that supratherapeutic doses cause macrophage accumulation and activation (Abstract, page unavailable). It also notes uPAR expression in monocytes, macrophages, neutrophils and bronchial epithelium, but does not show that those naturally occurring non-senescent cells were eliminated or otherwise affected by treatment. Its killing experiment used non-senescent leukemia cells engineered to express uPAR. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Anti-uPAR-CAR-T cells were effective in removing senescent cells in vitro and pre-cancerous and malignant cells in mouse models of liver and lung.

    “It was found that anti-uPAR-CAR-T cells were effective in removing senescent cells in vitro and pre-cancerous and malignant cells in mouse models of liver and lung in the presence of potentially toxic.350”

    From Inflammation and aging: signaling pathways and intervention therapies (2023) · cites this paper as [350]

    The paper reports that uPAR CAR T cells eliminated senescent cells in vitro, reduced senescent hepatocytes in mice, and decreased senescent tumor cells in a mouse lung adenocarcinoma model (Abstract; pages unavailable). It describes the liver cells as oncogene-induced senescent hepatocytes, not explicitly as pre-cancerous cells, so that characterization is not established by our copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Mice with lung adenocarcinomas exposed first to MEK and CDK4/6 inhibitors to induce senescence and then to uPAR-targeting CAR T cells to selectively kill senescent cells showed a marked delay in tumour growth.

    “Mice with lung adenocarcinomas were first exposed to a combination of MEK and CDK4/6 inhibitors to induce senescence, and then received uPAR- targeting CAR Tcells to selectively kill those senescent cells, leading to a marked delay in tumour growth 22 .”

    From Senescence and cancer — role and therapeutic opportunities (2022) · cites this paper as [22]

    The paper’s lung adenocarcinoma passage describes MEK and CDK4/6 inhibitor treatment followed by uPAR-targeted CAR T cells, and reports fewer senescent tumour cells and significantly prolonged survival. Extended Data Fig. 5 describes a survival analysis, not a measurement of tumour growth, so the claimed marked delay in tumour growth is not established by our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Recent work has shown that senolytic CAR T cell therapy can reduce senescence-associated diseases.

    “Exciting recent work has demonstrated that senolytic CAR T cell therapy can attenuate senescence-associated diseases226.”

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.
