Nutritional regulation of gut-brain immune crosstalk across the lifespan.
Review in Gut microbes, 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
The gut-brain immune axis integrates microbial, immune, and neural signals to regulate neurodevelopment, homeostasis, and disease susceptibility. Early-life nutrition, particularly human milk oligosaccharides, shapes beneficial microbiota composition, enhances hippocampal plasticity, promotes anti-inflammatory microglia polarization, and fosters immune tolerance. Gut microbiota-derived metabolites, including short-chain fatty acids, tryptophan derivatives and secondary bile acids, regulate microglia maturation, astrocyte function, T cell differentiation, neurotransmitter production, and vagus nerve signaling. These processes influence synaptic pruning, neurogenesis, and neuroinflammation. Adaptive immune cells in the central nervous system, notably meningeal and infiltrating CD4 T cells, further connect peripheral immunity to neuronal responses through cytokines, such as IL-4, IFNγ, and IL-17A. Nutritional imbalances may exacerbate disease-associated microglia and pathogenic T cell activity in Multiple Sclerosis, Alzheimer's disease, and autism spectrum disorders. In aging, diet helps mitigate "inflammaging" by countering metabolic shifts in microglia and lymphocytes. This review examines how nutrition modulates bidirectional gut-brain immune crosstalk across the lifespan.
