Randomized trial shows endothelial caveolin-1 influences thrombo-inflammation in acute ischemic stroke, indicating potential therapeutic targets.

The study aims to explore the role of endothelial caveolin-1 in regulating thrombo-inflammation during cerebral ischemia/reperfusion injury.
Analyzed serum caveolin-1 levels in acute ischemic stroke patients post-recanalization.
Utilized genetic manipulations with endothelial-specific adeno-associated virus and siRNA in transient middle cerebral artery occlusion model.
Examined thrombo-inflammation through microthrombosis formation, myeloid cell infiltration, and adhesion molecule expression.
Transcriptome analysis identified Rxrg as significantly changed following caveolin-1 knockdown in tMCAO mice.
RXR-γ siRNA supplementation reversed the reduction of thrombo-inflammation caused by caveolin-1 manipulation without affecting tight junction integrity.
Endothelial caveolin-1 and RXR-γ interaction influences infarct volume and neurological impairment in cerebral ischemia/reperfusion.
