Gut Microbiota-Derived Extracellular Vesicles Influence Alcohol Intake Preferences in Rats.
Article in Journal of extracellular vesicles, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
Growing preclinical and clinical evidence suggests a link between gut microbiota dysbiosis and problematic alcohol consumption. Extracellular vesicles (EVs) are key mediators involved in bacteria-to-host communication. However, their potential role in mediating addictive behaviour remains unexplored. This study investigates the role of gut microbiota-derived bacterial extracellular vesicles (bEVs) in driving high alcohol consumption. bEVs were isolated from the gut microbiota of a high alcohol-drinking rat strain (UChB rats), either ethanol-naïve or following chronic alcohol consumption and administered intraperitoneally or orally to alcohol-rejecting male and female Wistar rats. Both types of UChB-derived bEVs increased Wistar's voluntary alcohol consumption (three bottle choice test) up to 10-fold (p < 0.0001), indicating that bEVs are able and sufficient to transmit drinking behaviour across different rat strains. Molecular analysis revealed that bEVs administration did not induce systemic or brain inflammation in the recipient animals, suggesting that the increased alcohol intake triggered by UChB-derived bEVs operates through an inflammation-independent mechanism. Furthermore, we demonstrate that the vagus nerve mediates the bEV-induced increase in alcohol consumption, as bilateral vagotomy completely abolished the high drinking behaviour induced by both intraperitoneally injected and orally administered bEVs. Thus, this study identifies bEVs as a novel mechanism underlying gut microbiota-induced high alcohol intake in a vagus nerve-dependent manner.
