1 · What the graph read from 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.

2 · The registry

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

Alzheimer's disease (AD) is an irreversible neurodegenerative disease characterized by cognitive decline. The precise molecular mechanisms that underlie the pathogenesis of AD remain elusive. Here we show that glycoprotein nonmetastatic melanoma protein B (GPNMB) is produced by microglia and transferred to astrocytes through extracellular vesicles (EVs) in PS19 tau pathology mice. Tau is cleaved in microglia to generate N-terminal fragments that form a complex on mitochondria with Parkin/Nix and GPNMB, promoting the secretion of EVs containing mitochondria. Functional mitochondria transferred to astrocytes via EVs markedly improve astrocytic functions and attenuate the cognitive impairments and pathogenic features in PS19 mice. By contrast, microglial GPNMB deficiency eliminates mitochondrial EV secretion and mitochondrial transfer to astrocytes, thereby impairing astrocytic functions and exacerbating cognitive impairment in PS19-CcKO (CX3CR1 cre Gpnmb floxp) mice. GPNMB-enriched EVs from PS19 mice alleviate the pathological phenotypes of PS19 mice, offering potential insights for AD treatment.
