Abstract

Activation of the stimulator of interferon genes (STING) pathway promotes antitumor immunity but STING agonists have yet to achieve clinical success. Increased understanding of the mechanism of action of STING agonists in human tumors is key to developing therapeutic combinations that activate effective innate antitumor immunity. Here, we report that malignant pleural mesothelioma cells robustly express STING and are responsive to STING agonist treatment ex vivo. Using dynamic single-cell RNA sequencing of explants treated with a STING agonist, we observed CXCR3 chemokine activation primarily in tumor cells and cancer-associated fibroblasts, as well as T-cell cytotoxicity. In contrast, primary natural killer (NK) cells resisted STING agonist–induced cytotoxicity. STING agonists enhanced migration and killing of NK cells and mesothelin-targeted chimeric antigen receptor (CAR)-NK cells, improving therapeutic activity in patient-derived organotypic tumor spheroids. These studies reveal the fundamental importance of using human tumor samples to assess innate and cellular immune therapies. By functionally profiling mesothelioma tumor explants with elevated STING expression in tumor cells, we uncovered distinct consequences of STING agonist treatment in humans that support testing combining STING agonists with NK and CAR-NK cell therapies.

  • Treatment of melanoma PDOTS with a STING agonist (ADU-S100) had no impact on PDOTS viability, in contrast to TNFα/IFNγ +/- TBK1i.

    “Lastly, treatment of melanoma PDOTS with a STING agonist (ADU-S100 43,44 ) had no impact on PDOTS viability, in contrast to TNF α /IFN γ +/- TBK1i (Extended Data Fig. 9h).”
  • In post-cryoablated RMS 76-9STINGwt TME compared with RMS 76-9STING-/- TME in wild-type mice, there was a significant increase in total CD4+ T cells expressing IFN-γ and GZMB, NK cells, GZMB expression in CD8+ T cells, and Foxp3+ CD4+ cells.

    “we observed a significant increase in the total CD4+ T cells expressing IFN-γ (figure 4H) and granzyme B (GZMB; figure 4J),60–65 NK cells (figure 4N), and the amount of GZMB expression in CD8+ T cells (figure 4L) in the post-cryoablated RMS 76-9STINGwt TME as compared with RMS 76-9STING-/- TME in wild-type mice, as was Foxp3+ CD4+ cells (figure 4M).”

    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 [60]

    The Results section on dynamic scRNA-seq of MPM explants identifies granzyme-positive T cells and NK cells, but it does not report the claimed increases after cryoablation. Searches for RMS 76-9, cryoablation, and the STING-wild-type versus STING-knockout comparison found no passage addressing that experiment in our copy. (LLM, conf=0.75)

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.
