简介：
Overview
This study establishes a mouse model of cerebral ischemia-reperfusion to investigate the pathophysiology of stroke. The model involves distal ligation of the right middle cerebral artery and right common carotid artery, followed by restoration of blood flow after ischemia.
Key Study Components
Area of Science
- Neuroscience
- Stroke Research
- Animal Models
Background
- Cerebral ischemia-reperfusion is a critical area of study in stroke research.
- Understanding the immune response in the ischemic brain is essential for developing therapeutic strategies.
- This model allows for the examination of infarct volume and behavioral deficits.
- The low mortality rate makes it suitable for repeated experiments.
Purpose of Study
- To investigate the pathophysiology of stroke using a reliable mouse model.
- To assess the impact of ischemia-reperfusion on brain tissue and immune cell infiltration.
- To evaluate behavioral outcomes following cerebral ischemia-reperfusion.
Methods Used
- Two-vessel occlusion model for inducing cerebral ischemia.
- Distal ligation of the right middle cerebral artery and common carotid artery.
- Restoration of blood flow after 10 or 40 minutes of ischemia.
- Monitoring of surgical conditions and post-operative care for mice.
Main Results
- Induction of a stable infarct volume in the cortical areas.
- Characterization of immune cell infiltration in the ischemic brain.
- Assessment of behavioral deficits post-ischemia-reperfusion.
- Confirmation of blood flow disruption during the procedure.
Conclusions

- It allows for the evaluation of therapeutic interventions targeting ischemic injury.
- Further studies can leverage this model to explore immune responses in stroke.
What is the significance of this mouse model?
This model helps in understanding the mechanisms of stroke and testing potential treatments.
How is the ischemia induced in the model?
Ischemia is induced by distally ligating the right middle cerebral artery and common carotid artery.
What are the expected outcomes of the study?
Expected outcomes include the assessment of infarct volume and behavioral deficits.
What precautions are taken during the surgery?
Surgical tools are autoclaved, and the surgery area is sanitized with 70% ethanol.
What is the mortality rate associated with this model?
The mortality rate is low, making it suitable for repeated experiments.
How does this model contribute to stroke research?
It allows researchers to study the effects of ischemia-reperfusion on brain tissue and immune responses.
