Exosome Secretion Regulation in Mice with Acute Lung Injury.
Article in Journal of inflammation research, 2025. 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
Purpose: Acute lung injury (ALI) is a typical critical illness. Exosomes can regulate the development of pulmonary inflammation by modulating macrophage metabolism and behavior. During ALI, C-C motif chemokine ligand 2 (CCL2) is involved in the occurrence and maintenance of the inflammatory response, and the amount of CCL2 secreted by exosome increases. This study was aimed at investigating the role and mechanism of exosome -mediated CCL2 in sepsis-related ALI using a sepsis model in mice and rat type II alveolar epithelial cells. Furthermore, we explore the regulation of extracellular vesicle secretion in acute lung injury in mice. Methods: The sepsis group was pretreated with an exosome inhibitor to determine the extent of exosome release and alterations in inflammatory factors in the lung tissue. Furthermore, RLE-6TN cell-derived exosomes were cocultured with rat alveolar macrophages. Subsequently, an ALI rat model was constructed, and exosomes produced in vitro were injected into rats via the tail vein to detect the expression levels of inflammatory factors and elucidate macrophage polarization pathways. Results: After treatment with the exosome inhibitor, the number of exosomes and the expression of CCL2 in the lung tissue were significantly downregulated in the sepsis group. Exosomes secreted by lipopolysaccharide-treated rat type II alveolar epithelial cells stimulated the polarization of M1 macrophages, which resulted in morphological and functional changes. Conclusion: Exosome Secretion Regulation in Mice with Acute Lung Injury.
