However, the role of necroptosis in early brain injury after subarachnoid hemorrhage (SAH) is still unknown. The purpose of this study was to investigate whether necroptosis was involved in SAH-induced early brain injury, and to assess the possible neuroprotective effect of necrostatin-1 using an endovascular perforation rat model of SAH. Our results showed that the expression levels of necroptosis-related proteins including RIP1, RIP3 and MLKL in the basal cortex all increased at 3 hours after SAH (P<0.05) and peaked at 48 hours after SAH (P<0.05). However, they were greatly reduced after treatment with necrostatin-1 (P<0.05). Concurrently, neurologic outcomes were significantly improved after necrostatin-1 treatment (P<0.05). Furthermore, brain edema, blood–brain barrier disruption, necrotic cell death and neuroinflammation were also greatly inhibited after necrostatin-1 treatment. These results indicate that necroptosis is an important mechanism of cell death involved in the early brain injury after experimental SAH. Necrostatin-1 perhaps can serve as a promising neuroprotective agent for SAH treatment.
