Astrocytes play a pivotal role in neuronal survival in the setting of post-ischemic brain inflammation, but the astrocyte-derived mediators of ischemic brain injury remain to be defined. 2-(2-Benzofu-ranyl)-2-imidazoline (2-BFI) is a newly discovered ligand for high-affinity imidazoline I2 receptors (I2Rs) mainly located on the mitochondrial outer membrane in astrocytes. We previously reported that in a rat model of cerebral ischemia-reperfusion injury, 2-BFI limits infarct volume, reduces neurological impairment scores, and inhibits neuronal apoptosis in the ischemic penumbra. This study was performed to clarify the underlying mechanism in an astrocyte oxygen-glucose deprivation (OGD) model. The results show that 2-BFI reduces lipid peroxidation and inhibits mitochondria apoptotic pathways.
