Myeloid-derived-suppressor cells as regulators of the immune system

Open access

Abstract

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of cells that expand during cancer, inflammation and infection, and that have a remarkable ability to suppress T-cell responses. These cells constitute a unique component of the immune system that regulates immune responses in healthy individuals and in the context of various diseases. In this Review, we discuss the origin, mechanisms of expansion and suppressive functions of MDSCs, as well as the potential to target these cells for therapeutic benefit.

  • CD11b+Gr1+ myeloid cells are a heterogeneous group with known roles in tumor angiogenesis and T cell immunosuppression.

    “CD11b+Gr1+ myeloid cells are a heterogeneous group with previously identified roles in tumor angiogenesis and T cell immunosuppression (Gabrilovich and Nagaraj, 2009; Ostrand-Rosenberg and Sinha, 2009; Shojaei et al., 2007).”

  • Myeloid-derived suppressor cells suppress T-cell activity.

    “MDSCs play a role in the immune system through their suppressive action on T cells (116).”
  • MDSCs attenuate Teff and NK cell activity via arginase 1, iNOS, ROS, and peroxynitrite, regulate Treg differentiation, and induce immunosuppressive macrophages.

    “Through different mediators such as arginase 1, Inducible nitric oxide synthase (iNOS), reactive oxygen species (ROS), and peroxynitrite, MDSCs attenuate the activity of Teffs and NK cells (Gabrilovich and Nagaraj, 2009), regulate the differentiation of Tregs (Huang et al., 2006), and induce an immunosuppressive phenotype in macrophages (Sinha et al., 2007).”

  • Immunosuppressive myeloid cells can be differentiated/polarized for anti-tumor phenotypes.

    “On a similar note, immunosuppressive myeloid cells can be differentiated/polarized for anti‐tumor phenotypes [88, 89].”

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.
