Microglia Display Altered Spatial Morphology and Proteome After Stroke.
Article in Proteomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Microglia are abundantly distributed throughout the central nervous system (CNS) to play critical roles in neural development and homeostasis, and act as immune sentinels to constantly monitor their surrounding neural environment. Given their high reactivity to brain insults, we hypothesised that the cerebral microenvironment altered by ischaemic stroke would significantly impact microglial morphology and function in a spatially dependent manner. To investigate this, we examined regional gene expression changes associated with microglial activation and neuroinflammation, microglial morphology using 3D image reconstruction and unbiased proteomics at 24 h after transient middle cerebral artery occlusion (tMCAO). We found the microenvironment within the ischaemic infarct core has a distinct proinflammatory profile versus that of the sham-operated controls. Moreover, stroke induces region-specific changes to microglia morphology with those closer to the infarct displaying a more ameboid shape and less complex dendritic processes. Additionally, we identified 108 differentially expressed proteins in microglia that were isolated from the ipsilateral ischaemic hemisphere compared to those isolated from the contralateral hemisphere. These differentially expressed proteins are predicted to influence signalling pathways that mediate TNFα superfamily cytokine production, chemokine activities and leukocyte chemotaxis and migration. These findings support microglia as critical regulators of the inflammatory signalling after stroke.
