摘要: The treatment of stroke is limited by a short therapeutic window and lack effective clinical drugs. Methylene blue (MB) has been used in laboratories clinics since the 1890s. Few studies have reported neuroprotective role MB cerebral ischemia-reperfusion injury. However, whether how protects against acute ischemia (ACI) injury was unclear. In this study, we investigated effect on revealed that protected ACI augmenting mitophagy. Using rat middle artery occlusion (MCAO) model, demonstrated improved neurological function reduced infarct volume necrosis after These improvements depended mitochondrial structure function. caused disorder disintegration structure, while ameliorated destruction mitochondria. addition, mitophagy inhibited at 24 h augmented an oxygen-glucose deprivation (OGD) model vitro, further elevation membrane potential (MMP) under OGD conditions mediated contrast, exacerbating decline MMP during abolished MB-induced activation Taken together, promotes maintaining relatively high level, which contributes to decrease improvement function, thereby protecting
