Abstract

Ischemic stroke refers to the sudden loss of blood flow in a specific area of the brain. It is the fifth leading cause of mortality and the leading cause of permanent disability. The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) controls the production of several antioxidants and protective proteins and it has been investigated as a possible pharmaceutical target for reducing harmful oxidative events in brain ischemia. Each cell type exhibits different roles and behaviors in different phases post-stroke, which is comprehensive yet important to understand to optimize management strategies and goals for care for stroke patients. In this review, we comprehensively summarize the protective effects of Nrf2 in experimental ischemic stroke, emphasizing the role of Nrf2 in different cell types including neurons, astrocytes, oligodendrocytes, microglia, and endothelial cells during acute and chronic phases of stroke and providing insights on the neuroprotective role of Nrf2 on each cell type throughout the long term of stroke care. We also highlight the importance of targeting Nrf2 in clinical settings while considering a variety of important factors such as age, drug dosage, delivery route, and time of administration.

摘要

缺血性中风是指大脑特定区域的血流突然中断。它是第五大死亡原因,也是导致永久性残疾的主要原因。转录因子红细胞生成素 2 相关因子 2(Nrf2)控制着几种抗氧化剂和保护性蛋白的产生,它已被研究作为减少脑缺血中有害氧化事件的一种可能的药物靶点。每种细胞类型在中风后不同阶段都表现出不同的作用和行为,全面了解这一点对于优化中风患者的管理策略和护理目标非常重要。在这篇综述中,我们全面总结了 Nrf2 在实验性缺血性中风中的保护作用,强调了 Nrf2 在不同细胞类型中的作用,包括神经元、星形胶质细胞、少突胶质细胞、小胶质细胞和内皮细胞,在中风的急性和慢性阶段,并提供了关于 Nrf2 在中风护理的长期过程中对每种细胞类型的神经保护作用的见解。我们还强调了在临床环境中靶向 Nrf2 的重要性,同时考虑了多种重要因素,如年龄、药物剂量、给药途径和给药时间。
