Astrocyte-driven multicellular mechanisms of CNS repair and cerebroprotection.
Review in Journal of cerebral blood flow and metabolism : official journal of the International Society of Cerebral Blood Flow and Metabolism, 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
Astrocytes are central regulators of brain homeostasis, which respond dynamically to injury and disease by modulating neuronal activity, immune responses, and vascular function. Recent work has revealed that the diversity of astrocytic states and their context-dependent interactions with neighboring cells critically influence outcomes after central nervous system (CNS) injury and inflammation. This review synthesizes new insights into how astrocytes interact with microglia, neurons, and the neurovascular unit to shape neuroprotection and repair. We discuss how astrocyte-secreted proteins dynamically regulate synaptic remodeling following stroke; how regionally restricted lesion-remote astrocytes govern the specification of repair-associated microglia and promote white matter regeneration after trauma; and how signaling between astrocytes and microglia modulates neuronal survival in neurodegeneration. We further highlight emerging evidence linking disrupted astrocyte-endothelial cell interactions to neurodegenerative disease in humans. Together, these findings illustrate that astrocyte heterogeneity and multicellular communication define the balance between injury resolution and degeneration. Understanding these multidimensional astrocytic networks opens new avenues for therapeutic strategies aimed at promoting neuroprotection, restoring circuit function, and minimizing long-term neurological deficits.
