The polarization of immune cells in the tumour environment by TGFβ
Open accessAbstract
Transforming growth factor-beta (TGFbeta) is an immunosuppressive cytokine produced by tumour cells and immune cells that can polarize many components of the immune system. This Review covers the effects of TGFbeta on natural killer (NK) cells, dendritic cells, macrophages, neutrophils, CD8(+) and CD4(+) effector and regulatory T cells, and NKT cells in animal tumour models and in patients with cancer. Collectively, many recent studies favour the hypothesis that blocking TGFbeta-induced signalling in the tumour microenvironment enhances antitumour immunity and may be beneficial for cancer therapy. An overview of the current drugs and reagents available for inhibiting TGFbeta-induced signalling and their phase in clinical development is also provided.

CAFs secrete growth factors, proinflammatory cytokines, and chemokines, particularly TGF-β, IL-6, and CCL2, which recruit immunosuppressive cells into the tumor stroma and lead to immune escape.
“In addition, CAFs secrete substantial amounts of growth factors, proinflammatory cytokines, and chemokines, particularly TGF-β, IL-6, and CC-chemokine ligand 2, which recruit immunosuppressive cells into the tumor stroma and lead to immune escape 20-22.”
From TBX3 shapes an immunosuppressive microenvironment and induces immunotherapy resistance (2025) · cites this paper as [20]
The section on TGFβ’s effects on innate immune cells (page unavailable) says TGFβ-mediated macrophage recruitment into skin tumours has an important role in immune escape. But the paper does not identify CAFs as the source of those signals or support the claimed secretion and recruitment roles of IL-6 and CCL2; its discussion of regulatory-cell trafficking instead mentions CCL22 produced by tumour-associated macrophages.

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.
