Early-life gut microbiome maturity regulates blood-brain barrier and cognitive development.
Article in Gut microbes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The gut microbiome is an emerging factor in the neurobiology of disease. Blood-brain barrier (BBB) integrity is essential for proper brain function. However, the role the initial microbiome plays in BBB and brain development is unclear. In this study, we colonized germ-free pregnant mice with human full-term- or preterm-infant-derived gut microbiota, thereby establishing these communities in the resulting offspring. We discovered that mice harboring a full-term-associated microbiome exhibited stronger memory and learning capabilities and dramatically decreased early-life BBB permeability when compared to those with a prematurity-associated microbiome. Whole-brain single-cell RNA sequencing revealed downregulation of synaptic signaling genes in BBB cell types of mice with the prematurity-associated microbiome, indicating that microbiome maturity influences BBB transcriptional programs that support cognitive development. Comprehensive metagenomics and metabolomics uncovered bacterial populations and genomic pathways corresponding with decreased levels of circulating long-chain acylcarnitines and lysophosphatidylcholines in mice with the full-term-associated microbiome. Our findings highlight the microbiome as a therapeutic target for improving long-term neurodevelopmental outcomes due to its effect on the early-life BBB.
