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

Immune molecules and their cognate receptors are developmentally regulated in brain and dynamically expressed in the context of neurodevelopmental disorders. Despite the importance of immune molecules to brain wiring, a comprehensive map of the neuroimmune landscape is lacking in developing brain. Here we employed multiplexed in situ spatial transcriptomics to measure the expression of major immune ligands and receptors in developing mouse brain during mid and late gestation. Given the importance of maternal environment in shaping fetal neurodevelopment, we determined how embryonic neuroimmune landscape was altered after maternal immune activation (MIA) and maternal microbiome depletion. Our study revealed notable sex-specific patterns in gene expression and spatial architecture within developing brain. We observed changes in the CXCL12/CXCR7 chemokine network after MIA and microbiome depletion, suggesting a potential common mechanism underlying neural progenitor abnormalities. This resource underscores how the maternal environment programs precise regulation of immune molecules in developing brain, highlighting sex-specific vulnerability.
