Abstract

The innate immune system detects infection by using germline-encoded receptors that are specific for conserved microbial molecules. The recognition of microbial ligands leads to the production of cytokines, such as type I interferons (IFNs), that are essential for successful pathogen elimination. Cytosolic detection of pathogen-derived DNA is one major mechanism of inducing IFN production, and this process requires signalling through TANK binding kinase 1 (TBK1) and its downstream transcription factor, IFN-regulatory factor 3 (IRF3). In addition, a transmembrane protein called STING (stimulator of IFN genes; also known as MITA, ERIS, MPYS and TMEM173) functions as an essential signalling adaptor, linking the cytosolic detection of DNA to the TBK1-IRF3 signalling axis. Recently, unique nucleic acids called cyclic dinucleotides, which function as conserved signalling molecules in bacteria, have also been shown to induce a STING-dependent type I IFN response. However, a mammalian sensor of cyclic dinucleotides has not been identified. Here we report evidence that STING itself is an innate immune sensor of cyclic dinucleotides. We demonstrate that STING binds directly to radiolabelled cyclic diguanylate monophosphate (c-di-GMP), and we show that unlabelled cyclic dinucleotides, but not other nucleotides or nucleic acids, compete with c-di-GMP for binding to STING. Furthermore, we identify mutations in STING that selectively affect the response to cyclic dinucleotides without affecting the response to DNA. Thus, STING seems to function as a direct sensor of cyclic dinucleotides, in addition to its established role as a signalling adaptor in the IFN response to cytosolic DNA. Cyclic dinucleotides have shown promise as novel vaccine adjuvants and immunotherapeutics, and our results provide insight into the mechanism by which cyclic dinucleotides are sensed by the innate immune system.

  • STING is a major pathway for the detection of immunogenic tumors and initiation of a spontaneous T cell response.

    “the stimulator of interferon genes (STING) has been shown to be a major pathway for the detection of immunogenic tumors and initiation of a spontaneous T cell response18–21.”

    From Epigenetic state determines the in vivo efficacy of STING agonist therapy (2023) · cites this paper as [21]

    The paper’s Abstract describes STING as a sensor of cyclic dinucleotides and an adaptor in the interferon response to cytosolic DNA. Searches for immunogenic tumors, tumor detection, and spontaneous T-cell responses found no passage in our copy addressing those parts of the claim. (LLM, conf=0.76)

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.
