Takeaway
IL-17 plays a role in delayed cerebral injury following aneurysmal subarachnoid hemorrhage.
Why this matters
Aneurysmal subarachnoid hemorrhage (SAH) is associated with significant long term cognitive and physical disability, including delayed cerebral injury (DCI).
Inflammatory responses, in particular neutrophil accumulation, have also been linked to DCI. A better understanding of the pathology of DCI following an SAH may allow earlier intervention to potential delay the development of DCI.
