Ischemic stroke accounts for 80% in stroke patients, which has a high rate of disability and fatality. Ischemic stroke seriously affects the quality of life of patients, and caused serious economic and so-cial burdens. Ischemic stroke was due to the reduction or complete interruption of the blood flow of the local blood supply arteries of the brain tissue in a short period of time, resulting in ischemia and hypoxia of the brain tissue in the ischemic area, which led to irreversible neuronal damage. The degree of damage depends on the duration of ischemia, severity and location. Studies had shown that the pathophysiological mechanisms of ischemic stroke include: regional cerebral vascular hy-poperfusion, excitotoxicity, oxidative stress, blood-brain barrier dysfunction, microvascular injury, inflammatory response, and apoptosis of nerve cells and endothelial cells. Nuclear factor E2-related factor 2 (Nrf2) was one of the main regulators of endogenous antioxidant defense. When hypoxia, oxidative stress or inflammatory response occurs, Nrf2 combines with Keap1 factor to regulate downstream factors and play an anti-oxidative role. Nrf2 signaling pathway played a role of an-ti-apoptosis, reducing inflammatory damage, reducing calcium overload, anti-oxidative stress and other functions, maintaining mitochondrial homeostasis and protecting brain tissue. This article reviews the role of Nrf2 signaling pathway in ischemic stroke, research progress and Nrf2 agonists in ischemic stroke. %K 缺血性脑卒中,Keap1/Nrf2,氧化应激,炎症反应
