Targeting PD-L1 for Ischemic Stroke Recovery: Age-Dependent Modulation of Immune and BBB Pathways.
Article in CNS neuroscience & therapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectiveAging has a profound impact on the pathophysiology of ischemic stroke and the effectiveness of therapeutic interventions. This study aims to evaluate the therapeutic efficacy of programmed death-ligand 1 (PD-L1) monoclonal antibody (mAb) in modulating immune responses and neurovascular repair following ischemic stroke, with a focus on age-dependent differences.
methodsYoung and aged mice were subjected to middle cerebral artery occlusion (MCAO) followed by PD-L1 mAb treatment. RNA sequencing, immunofluorescence, and molecular analyses were employed to assess immune modulation, blood-brain barrier (BBB) integrity, and functional recovery.
resultsRNA sequencing revealed significant differential gene expression in ischemic brain tissues, with CD274 (PD-L1) prominently upregulated among immune checkpoint-related genes in young mice. Immunofluorescence confirmed PD-L1 expression in microglia/macrophages, with significantly higher upregulation in young mice. PD-L1 mAb treatment showed superior efficacy in young mice, significantly reducing infarct volume, enhancing neurological recovery, and preserving BBB integrity through greater upregulation of tight junction proteins such as ZO-1, Claudin-5, and Occludin compared to aged mice. It also more effectively reduced neuroinflammation, apoptosis, and pro-inflammatory cytokines (TNF-α, IL-1β), eliciting stronger spleen responses in young mice. These findings underscore the age-dependent advantages of PD-L1-targeted therapies for ischemic stroke recovery.
conclusionsPD-L1 plays a critical role in ischemic stroke recovery, with PD-L1 mAb treatment demonstrating age-dependent therapeutic efficacy by enhancing BBB integrity, reducing neuroinflammation and apoptosis, and modulating peripheral immune responses.
