To summarize the mechanisms underlying post-stroke immunosuppression and explore their interactions within a neuroimmune network, emphasizing its clinical significance.
Key Findings:
Stroke triggers a biphasic immune response: an early inflammatory reaction followed by peripheral immunosuppression, with mechanisms including DAMPs.
Stroke-induced immunosuppression (SIIS) is associated with increased susceptibility to infections, particularly pneumonia.
Mechanisms of SIIS include activation of the autonomic nervous system, hypothalamic-pituitary-adrenal axis, changes in lymphocyte populations, and the role of DAMPs.
Interpretation:
The findings suggest that post-stroke immunosuppression is a significant factor influencing patient outcomes, warranting further investigation into its mechanisms and potential therapeutic targets, particularly in clinical settings.
Limitations:
The review primarily focuses on mechanisms studied in isolation, potentially overlooking their interactions, such as the interplay between neuroinflammation and systemic immune responses.
The adaptive significance of the immunosuppressive state remains unresolved, with examples of conditions where similar patterns occur.
Conclusion:
Understanding the transition from neuroinflammation to systemic immune dysfunction is crucial for developing therapeutic strategies to mitigate post-stroke complications, particularly in discerning adaptive versus maladaptive responses.
Over two days, specialists across neurology, neurosurgery and related subspecialties came together to discuss advances in stroke care, epilepsy, movement disorders, neurodegenerative disease, neuro-oncology, brain and spine surgery, interventional pain management and emerging technologies.
