Hypothesis
This study investigates the correlation between Rho kinase (ROCK) and microvascular damage in rat brains subjected to middle cerebral artery occlusion and reperfusion.
Conclusion
The study provides strong evidence that ROCK mediates microvascular damage and suggests that ROCK is a promising therapeutic target for stroke.
Supporting Evidence
- ROCK expression increased significantly after reperfusion compared to the sham group.
- Brain EB content increased significantly after reperfusion, indicating increased BBB permeability.
- Fasudil treatment decreased brain EB content and increased Laminin expression.
Takeaway
This study found that a protein called Rho kinase can cause damage to tiny blood vessels in the brain after a stroke, but a special medicine can help protect those vessels.
Methodology
The study used real-time quantitative PCR, immunofluorescence, and Evans Blue dye to assess microvascular damage and the effects of the ROCK inhibitor fasudil in rat models.
