Abstract

Stimulator of interferon genes (STING) was initially described as a sensor of intracellular bacterial and viral DNA and a promising adjuvant target in innate immune cells; more recently STING has also been shown to detect endogenous DNA and play a role in tumor immunity and autoimmune disease development. Thus far STING has been studied in macrophages and dendritic cells. In this study, to our knowledge we provide the first evidence of STING activation in T cells, in which STING agonists not only provoke type I IFN production and IFN-stimulated gene expression, mirroring the response of innate cells, but are also capable of activating cell stress and death pathways. Our results suggest a re-evaluation of STING agonist–based therapies may be necessary to identify the possible effects on the T cell compartment. Conversely, the effects of STING on T cells could potentially be harnessed for therapeutic applications.

  • STING activity induces T cell apoptosis.

    “as recent evidence demonstrated that STING activity induces T cell apoptosis,85–87”

    From Functional tumor cell-intrinsic STING, not host STING, drives local and systemic antitumor immunity and therapy efficacy following cryoablation (2023) · cites this paper as [87]

    The Results and Discussion section (“STING activation triggers T cell death”; page not provided) reports STING-dependent T-cell death in vitro and evidence implicating an apoptotic pathway. But it also suggests necroptosis can contribute and reports no T-cell death in its short-term in vivo experiment, so the unqualified claim that STING activity induces T-cell apoptosis overstates the finding. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • It was proposed that STING agonist can induce T cell death through activation of proapoptotic transcriptional programs.

    “Although it was proposed that STING agonist can induce T cell death through the activation of proapoptotic transcriptional programs58, recent studies have indicated that this effect depends on the type and doses of STING agonists59,60.”

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.
