Gut microbiota-mediated neuroinflammation following stroke: mechanisms and intervention strategies.
Review in Journal of translational medicine, 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
backgroundStroke is a complex and highly heterogeneous acute cerebrovascular disease characterized by high incidence, disability rates, and mortality. The occurrence of a stroke is the result of a series of chain reactions. Neuroinflammation, as a core component of the pathological process of stroke, serves as the dynamic hub of this chain of reactions. It acts both as a driving force in disease progression and a key regulator of functional recovery. Increasing evidence indicates that the gut microbiota has a dynamic coupling relationship with the neuroinflammatory pathological processes involved in stroke. This review aimed to explore the mechanisms by which the gut microbiota influences neuroinflammation following stroke and to evaluate its therapeutic potential in stroke. MAIN BODY: Following a stroke, up to 50% of patients have pathophysiological changes in the gastrointestinal tract, which are closely associated with delayed recovery, increased mortality, and worsened neurological outcomes. The gut microbiota can modulate post-stroke neuroinflammation through multiple pathways, including immune regulation (innate and adaptive immunity), neural signal transmission (vagus nerve and enteric nervous system), neuroendocrine transmission (hypothalamus-pituitary-adrenal axis), and gut microbiota metabolite pathways. This "central-peripheral-central" feedback loop is considered a potential intervention target. In this review, we summarized the characteristics of gut microbiota alterations following stroke, elucidated its mechanisms of action in neuroinflammation, and explored gut microbiota-based intervention strategies and their limitations. Finally, we proposed directions to provide new insights and references for clinical translation for the prevention and treatment of stroke.
conclusionsThe gut microbiota plays a key role in post-stroke pathology. The gut microbiota modulates the onset and progression of post-stroke neuroinflammation through multidimensional mechanisms via the "immune-neuro-endocrine" feedback pathway at multiple levels. Interventions targeting the gut microbiota can not only suppress excessive inflammation but also repair neural networks, ultimately improving functional outcomes after stroke.
