Abstract

Spontaneous tumor-initiated T cell priming is dependent on IFN-β production by tumor-resident dendritic cells. On the basis of recent observations indicating that IFN-β expression was dependent upon activation of the host STING pathway, we hypothesized that direct engagement of STING through intratumoral (IT) administration of specific agonists would result in effective anti-tumor therapy. After proof-of-principle studies using the mouse STING agonist DMXAA showed a potent therapeutic effect, we generated synthetic cyclic dinucleotide (CDN) derivatives that activated all human STING alleles as well as murine STING. IT injection of STING agonists induced profound regression of established tumors in mice and generated substantial systemic immune responses capable of rejecting distant metastases and providing long-lived immunologic memory. Synthetic CDNs have high translational potential as a cancer therapeutic.

  • In host dendritic cells, STING-mediated IFN-β induction is essential for their activation and the cross-priming of cytotoxic T cells.

    “In host dendritic cells, STING-mediated IFN-β induction has been well characterized and shown to be essential for their activation and the cross-priming of cytotoxic T cells22,23.”

    From Epigenetic state determines the in vivo efficacy of STING agonist therapy (2023) · cites this paper as [22]

    The Results report STING-dependent IFN-β production and activation markers in dendritic cells, while the Introduction describes type I IFN signaling as critical for tumor-specific T-cell priming and dendritic-cell cross-presentation. However, the paper does not establish that IFN-β induction itself is essential for dendritic-cell activation or cross-priming; those are more specific causal claims than the cited passages support.

  • Direct activation of the host STING pathway through intratumoral injections of synthetic cyclic dinucleotides is an attractive therapeutic strategy in multiple preclinical cancer models.

    “Direct activation of the host STING pathway through intratumoral injections of synthetic cyclic dinucleotides has shown to be an attractive therapeutic strategy in multiple preclinical cancer models22,25,42.”
  • Natural and artificially synthetic cyclic dinucleotides have been developed as STING agonists for cancer immunotherapy.

    “Sharing similar structures and biological characteristics with cGAMP, some natural and artificially synthetic cyclic dinucleotides (CDNs) are developed as STING agonists for cancer immunotherapy [265–267].”

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.
