Systemic Propagation of STING Signalling via Generation of Large Extracellular Vesicles.
Article in Journal of extracellular vesicles, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Large extracellular vesicles (EVs) derived from tumour cells play important roles in tumour formation and progression. However, it remains unclear why malignant cells produce these EVs and how they act in vivo. We employ a well-characterized Drosophila tumour model and demonstrate that large EV biogenesis from malignant cells is an evolutionarily conserved process. Our study uncovers an essential role for the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway, which mediates the innate immune response to cytosolic DNA, in driving large EV biogenesis and inducing a systemic immune response to tumours. STING engages a signalling axis comprising JNK and FAK-independent of TANK-binding kinase 1 (TBK1) and inhibitor of nuclear factor κB kinase (IKKβ)-to drive large EV biogenesis in both Drosophila and human malignant cells. Transplantation of large EVs from Drosophila tumours to wild type larvae is sufficient to recapitulate the systemic immune response to tumours by activating STING signalling in macrophage-like cells. Thus, our study establishes a novel animal model for studying large EVs derived from malignant cells and provides insights into how STING signalling propagates from tumour cells to the immune system via large EV biogenesis, inducing a systemic immune response to tumours.
