RIG-I agonists promote antigen-spreading and facilitate durable CAR-T responses in pancreatic ductal adenocarcinoma.
Article in Journal for immunotherapy of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPancreatic ductal adenocarcinoma (PDAC) remains largely refractory to chimeric antigen receptor (CAR)-T cell therapy. Insufficient T cell infiltration, a highly immunosuppressive microenvironment, and antigen loss pose major challenges for CAR-T cell therapy.
methodsWe investigated therapeutic synergies of synthetic 5'-triphosphate RNA (3p-RNA), an agonist of the cytoplasmic double-stranded RNA sensor Retinoic Acid Inducible Gene I (RIG-I), and CAR-T cell therapy using syngeneic and human xenograft PDAC models. Tumor growth, chemokine secretion, immune-cell composition, CAR-T persistence, and endogenous T cell responses were assessed by flow cytometry, multiplex cytokine arrays, Enzyme-linked Immunospot (ELISpot), and vaccination-challenge.
results3p-RNA provoked rapid type I interferon accompanied with chemokine ligand CCL5 and CXCL9/10/11 secretion, creating chemokine gradients that recruited chemokine receptor CCR5
conclusionsIntratumoral RIG-I priming reprograms the PDAC microenvironment, transforming a non-responsive cancer into a CAR-T-permissive one, supporting durable, poly-antigenic immunity. These findings position 3p-RNA as a rapid, clinically tractable co-therapy to extend CAR-T efficacy to solid tumors.
