Abstract

Significance: Cancer immune evasion is well described. In some cases, this may be overcome by enhancing T-cell responses. We show that despite the presence of antitumor T cells, immunotherapeutic antibodies are ineffective in a murine pancreatic cancer model recapitulating the human disease. Removing the carcinoma-associated fibroblast (CAF) expressing fibroblast activation protein (FAP) from tumors permitted immune control of tumor growth and uncovered the efficacy of these immunotherapeutic antibodies. FAP + CAFs are the only tumoral source of chemokine (C-X-C motif) ligand 12 (CXCL12), and administering AMD3100, an inhibitor of chemokine (C-X-C motif) receptor 4, a CXCL12 receptor, also revealed the antitumor effects of an immunotherapeutic antibody and greatly diminished cancer cells. These findings may have wide clinical relevance because FAP + cells are found in almost all human adenocarcinomas.

  • CAFs are the major source of CXCL12 in many tumours.

    “targeting CXCL12 signalling could be considered to be targeting CAFs as they are the major source of the chemokine in many tumours121.”

    From A framework for advancing our understanding of cancer-associated fibroblasts (2020) · cites this paper as [121]

    The paper identifies FAP+ CAFs as the principal source of CXCL12 in its pancreatic tumour model (p. 1) and reports FAP+ cells as the source in a Lewis lung carcinoma model (p. 2). It does not establish that CAFs are the major source across “many tumours”; its discussion of wider relevance is tentative (p. 4). (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Most studies have suggested an immunosuppressive role of CAFs.

    “most studies have suggested an immunosuppressive role of CAFs121”

    From A framework for advancing our understanding of cancer-associated fibroblasts (2020) · cites this paper as [121]

    The paper reports immunosuppression mediated by FAP-positive CAFs in a murine pancreatic cancer model (p. 1) and mentions a previous murine tumor study with a similar finding (p. 1). It does not establish that most studies have suggested an immunosuppressive role for CAFs generally. (LLM, conf=0.86)

  • Interference with the action of CXCL12 produced by CAFs promotes T cell-mediated tumour control.

    “Interference with the action of CXCL12 produced by CAFs promotes T cell-mediated tumour control16,121,122”
  • apCAF transcriptional profiles overlap with mesothelial cells and are postulated to derive from a mesothelial origin.

    “the transcriptional profiles of apCAFs overlap with mesothelial cells150, and based on lineage tracing studies in mice have been postulated to derive from a mesothelial origin145”

  • Activated fibroblasts can further differentiate into myofibroblasts that express α-smooth muscle actin.

    “They can further differentiate into myofibroblasts that express α-smooth muscle actin232.”

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.
