Abstract:

Microglia, a member of mononuclear phagocyte system, plays a significant role in maintaining homeostasis in central nervous system(CNS). As a subtype of stroke, subarachnoid hemorrhage (SAH)leads to an early brain injury within 72 hours and a delayed brain injury in 3-5 days. Vasospasm used to be regarded as a crucial mechanism of brain injury after subarachnoid hemorrhage, but recently increasing attention is focused on inflammation in brain injury. Microglia polarize to M1 type to act as an pro-inflammatory agent or to M2 type to become a neuro-protector in inflammation in both early stage and delay stage after subarachnoid hemorrhage. Here, we summarize researches on the role of microglia in the brain injury after subarachnoid hemorrhage, to find the research hotspot and provide potential targets for further clinical investigations.

Key words: Subarachnoid hemorrhage, Microglia, Brain injury
