Lung Tissue Extracellular Vesicles-Mediated Delivery of miR-128-3p as a Novel Mechanism of Acute Lung Inflammation.
Article in International journal of nanomedicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background: Emerging evidence links macrophage overactivation to sepsis-associated acute lung injury (ALI), yet the role of lung tissue-derived extracellular vesicles (Ti-EVs) in this process remains unclear. This study combines transcriptomic profiling and functional validation to reveal how Lung Ti-EVs mediate macrophage polarization through miRNA-dependent NLRP3 inflammasome activation. Methods: We established a sepsis mouse model, extracted and characterized lung tissue-derived EVs, performed high-throughput transcriptome sequencing and bioinformatics analysis. Intratracheal administration of these EVs to wild-type C57BL/6 mice revealed their effects on pulmonary inflammation, macrophage polarization, and proliferation. In vitro co-culture experiments with Raw264.7 macrophages further validated these findings and explored underlying mechanisms. Results: We identified extracellular vesicles (EVs) enriched in lung tissues from septic ALI mice, selectively carrying miRNAs including miR-128-3p. In vivo administration of these EVs exacerbated pulmonary inflammation by expanding M1 macrophage populations, while in vitro experiments demonstrated EV-mediated miR-128-3p delivery to macrophages stimulated TNF-α and IL-6 production. Mechanistically, miR-128-3p promoted macrophage proliferation and inflammatory responses by targeting Rab20.
