Abstract

Background & aims Several studies have shown that development of hepatocellular carcinoma (HCC) generates a number of immune suppressive mechanisms in these patients. Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of cells that have been shown to inhibit T-cell responses in tumor-bearing mice, but little is known about these cells in humans owing to a lack of specific markers. In this study, we have investigated the frequency and function of a new population of MDSC denoted here as CD14(+)HLA-DR(-/low) in HCC patients. We have also identified a novel, MDSC-mediated immune regulatory pathway in these patients.Methods We have directly isolated and characterized MDSCs for phenotype and function from peripheral blood (n = 111) and tumor (n = 12) of patients with HCC.Results The frequency of CD14(+)HLA-DR(-/low) cells in peripheral blood mononuclear cells (PBMC) from HCC patients was significantly increased in comparison with healthy controls. CD14(+) HLA-DR(-/low) cells were unable to stimulate an allogeneic T-cell response, suppressed autologous T-cell proliferation, and had high arginase activity, a hallmark characteristic of MDSC. Most important, CD14(+)HLA-DR(-/low) cells from HCC patients induced a CD4(+)CD25(+)Foxp3(+) regulatory T-cell population when cocultured with autologous T cells.Conclusion CD14(+)HLA-DR(-/low) cells are a new population of MDSC increased in blood and tumor of HCC patients. We propose a new mechanism by which MDSC exert their immunosuppressive function, through the induction of CD4(+)CD25(+)Foxp3(+) regulatory T cells in cocultured CD4(+) T cells. Understanding the mechanism of action of MDSC in HCC patients is important in the design of effective immunotherapeutic protocols.

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

  • The liver contains abundant myeloid-derived suppressor cells that produce factors suppressing T cell activation.

    “The liver also contains an abundance of MDSCs that produce factors suppressing T cell activation63.”

    From Adjuvant and neoadjuvant immunotherapies in hepatocellular carcinoma (2024) · cites this paper as [63]

    The Discussion (page not available in our copy) reports that MDSCs are increased in the tumors and peripheral blood of hepatocellular carcinoma patients and suppress T-cell responses through arginase activity. It does not establish that the liver generally contains abundant MDSCs; its finding is specific to patients with liver cancer. (LLM, conf=0.87)

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.
