Molecular Mechanism Analysis of Oxidative Stress in Stroke

Oxidative stress is caused by reactive oxygen species (ROS) during cerebral ischemia, potentially leading to cell death and ultimately brain death after reperfusion. Especially during reperfusion, superoxide anion radicals, hydroxyl radicals, and nitric oxide (NO) are produced, which can cause lipid peroxidation, inflammation, and apoptosis. The cerebral vasculature is a major target of oxidative stress, which plays a key role in the pathogenesis of ischemic brain injury following cerebrovascular attacks. In addition, mitochondrial dysfunction is caused after stroke, and oxidative stress further aggravates mitochondrial damage. Actively protecting mitochondrial function, resisting oxidation, scavenging free radicals, and mitigating oxidative stress have become effective strategies to save neurons from the pathological process of cerebral ischemia-reperfusion.
