Abstract

Tumours have developed strategies to interfere with most steps required for anti-tumour immune responses. Although many populations contribute to anti-tumour responses, tumour-infiltrating cytotoxic T cells dominate, hence, many suppressive strategies act to inhibit these. Tumour-associated T cells are frequently restricted to stromal zones rather than tumour islands, raising the possibility that the tumour microenvironment, where crosstalk between malignant and “normal” stromal cells exists, may be critical for T cell suppression. We provide evidence of direct interactions between stroma and T cells driving suppression, showing that cancer-associated fibroblasts (CAFs) sample, process and cross-present antigen, killing CD8 + T cells in an antigen-specific, antigen-dependent manner via PD-L2 and FASL. Inhibitory ligand expression is observed in CAFs from human tumours, and neutralisation of PD-L2 or FASL reactivates T cell cytotoxic capacity in vitro and in vivo. Thus, CAFs support T cell suppression within the tumour microenvironment by a mechanism dependent on immune checkpoint activation.

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

  • Antigen cross presentation by CAFs has been observed and may lead to CD4+ T cell activation and suppression of CD8+ T cells.

    “More recently, antigen cross presentation by CAFs has been observed117, and this may lead to CD4+ T cell activation and suppression of CD8+ T cells118.”
  • Fibroblasts can boost angiogenesis in in vitro assays.

    “fibroblasts can boost angiogenesis in in vitro assays, with exciting advances in the development of microfluidic angiogenesis models, and an increasing number of studies have shown how they can alter T cell functionality118,161,162.”

    From A framework for advancing our understanding of cancer-associated fibroblasts (2020) · cites this paper as [118]

    The Methods describe fibroblast–T-cell co-cultures and collagen-gel contraction assays, but no in vitro angiogenesis assay or finding that fibroblasts boost angiogenesis (searched: angiogenesis, vascular sprouting, and tube formation). The Discussion instead supports the sentence’s later, citation-adjacent point that fibroblasts alter T-cell function. (LLM, conf=0.76)

  • CAFs show characteristics of activated fibroblasts and/or myofibroblasts, consistent with the chronic inflammation and mechanical tension in tumors.

    “CAFs show characteristics of activated fibroblasts and/or myofibroblasts, consistent with the chronic inflammation and mechanical tension in tumors12,233,234.”

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.
