Abstract

T lymphocytes undergo proliferation arrest when exposed to tryptophan shortage, which can be provoked by indoleamine 2,3-dioxygenase (IDO), an enzyme that is expressed in placenta and catalyzes tryptophan degradation. Here we show that most human tumors constitutively express IDO. We also observed that expression of IDO by immunogenic mouse tumor cells prevents their rejection by preimmunized mice. This effect is accompanied by a lack of accumulation of specific T cells at the tumor site and can be partly reverted by systemic treatment of mice with an inhibitor of IDO, in the absence of noticeable toxicity. These results suggest that the efficacy of therapeutic vaccination of cancer patients might be improved by concomitant administration of an IDO inhibitor.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • NSCLC patients have increased tryptophan catabolism compared with the general population, leading to higher serum kynurenine, which is associated with advanced stage at diagnosis, poor prognosis and chemotherapy resistance.

    “Compared with the general population, patients with NSCLC have increased tryptophan catabolism, which leads to higher kynurenine serum concentrations and has been associated with advanced stage disease at diagnosis, an unfavourable prognosis and resistance to chemotherapy148,149.”
  • IDO is considered an immune checkpoint in peripheral tolerance because tryptophan absence inhibits T cell proliferation and T cell apoptosis contributes to immunosuppression.

    “Therefore, IDO is viewed as an immune checkpoint involved in peripheral immune tolerance owing to the fact that, in the absence of tryptophan, T cell proliferation is inhibited and T cell apoptosis contributes to immunosuppression148.”

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.
