Summary
White blood cells (WBCs) contribute to secondary brain damage following transient focal cerebral ischemia. Interventions targeting WBC inflammatory function are reviewed for their efficacy and impact on brain injury.
Area of Science:
- Neuroscience
- Immunology
- Pathophysiology
Background:
- White blood cells (WBCs) are crucial for host defense.
- Their role in secondary brain damage after cerebral ischemia is under investigation.
- Polymorphonuclear leukocytes are of particular interest.
Purpose of the Study:
- To survey interventions that interfere with WBC inflammatory function.
- To evaluate the efficacy and side effects of these interventions.
- To assess the evidence for WBCs as mediators of cerebral ischemia.
Main Methods:
- Review of studies using antileukocyte interventions in experimental cerebral ischemia models.
- Analysis of various global and focal cerebral ischemia models with and without reperfusion.
- Evaluation of effects on cerebral and systemic parameters.
Main Results:
- WBCs appear to contribute to secondary brain damage in transient focal cerebral ischemia.
- Results across different models have sometimes been contradictory.
- Evidence suggests WBCs are important factors in cerebral ischemia.
Conclusions:
- WBCs likely contribute to secondary brain damage in experimental transient focal cerebral ischemia.
- Further research is needed to clarify their precise role and optimize interventions.
- Targeting WBC inflammation may be a therapeutic strategy for ischemic stroke.
