Impaired TGFβ Signaling in Plaque-Associated Microglia.
Article in Biomolecules, 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
Aging and Alzheimer's disease (AD) are associated with profound changes in glial cell morphology and signaling. This study investigates the three-dimensional morphology of microglia and the intracellular localization of phosphorylated SMAD proteins as downstream effectors of transforming growth factor β (TGF-β) signaling in the amyloid precursor protein and presenilin-1 (APP/PS1) transgenic mouse model of Alzheimer's disease. Using confocal microscopy and Simple Neurite Tracer software, we reconstructed and quantitatively analyzed glial cell morphology in aged wild-type and APP/PS1 mice. Immunofluorescence staining revealed altered pSMAD2 distribution in microglia, suggesting impaired canonical TGF-β signaling. Our findings indicate a disturbed glial morphology and dysfunctional TGF-β signaling cascade in the APP/PS1 model, underlining their potential role in Alzheimer's disease pathogenesis.
