Coordinated transcriptional shifts in microglia and oligodendrocytes from neurodevelopment to inflammaging.
Article in npj aging, 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
Glial cells shape brain development and aging, yet whether distinct glial lineages undergo coordinated lifespan transitions remains unclear. Although microglial aging states and oligodendrocyte vulnerability in neurodegeneration are well described, it remains unclear whether these programs evolve independently or in a temporally related manner. Here, we analyzed Mouse Cell Atlas single-cell RNA-seq data spanning embryogenesis to 24 months. Microglia and oligodendrocytes were the most transcriptionally dynamic glial populations, whereas astrocyte module activity was primarily observed during development. Microglia and oligodendrocytes exhibited similar late-life increases in inflammatory and senescence-associated modules, supported by cross-correlation (Pearson r ≈ 0.98; Max_CCF ≈ 0.98), dynamic time warping (DTW ≈ 6.16), and a large effect size (Cohen's d ≈ 11.08). These patterns were also supported by mixed glial contexts (p = 1.85 × 10⁻³). Together, these results identify a parallel transcriptional shift in microglia and oligodendrocytes from neurodevelopment to inflammaging and suggest that shared temporal programs across glial lineages may contribute to neurodegenerative vulnerability. This quantitative framework for assessing temporal similarity may be broadly applicable to other biological systems involving dynamic cellular state transitions.
