Ischemic stroke poses significant challenges in terms of mortality and disability rates globally. A key obstacle to the successful treatment of ischemic stroke lies in the limited efficacy of administering therapeutic agents. Leveraging the unique properties of nanoparticles for brain targeting and crossing the blood-brain barrier, researchers have engineered diverse nanoparticle-based drug delivery systems to improve the therapeutic outcomes of ischemic stroke. This review provides a concise overview of the pathophysiological mechanisms implicated in ischemic stroke, encompassing oxidative stress, glutamate excitotoxicity, neuroinflammation, and cell death, to elucidate potential targets for nanoparticle-based drug delivery systems. Furthermore, the review outlines the classification of nanoparticle-based drug delivery systems according to these distinct physiological processes. This categorization aids in identifying the attributes and commonalities of nanoparticles that target specific pathophysiological pathways in ischemic stroke, thereby facilitating the advancement of nanomedicine development. The review discusses the potential benefits and existing challenges associated with employing nanoparticles in the treatment of ischemic stroke, offering new perspectives on designing efficacious nanoparticles to enhance ischemic stroke treatment outcomes.
缺血性脑卒中在全球范围内的死亡率和残疾率方面构成重大挑战。成功治疗缺血性脑卒中的一个主要障碍在于治疗药物的疗效有限。研究人员利用纳米粒子针对大脑的独特特性和穿透血脑屏障的能力,设计了多种基于纳米粒子的药物传递系统,以改善缺血性脑卒中的治疗效果。本综述简要概述了与缺血性脑卒中相关的病理生理机制,包括氧化应激、谷氨酸兴奋性毒性、神经炎症和细胞死亡,以阐明基于纳米粒子的药物传递系统的潜在靶点。此外,本综述根据这些不同的生理过程对基于纳米粒子的药物传递系统进行了分类。这种分类有助于确定针对缺血性脑卒中特定病理生理途径的纳米粒子的特性和共性,从而促进纳米医学的发展。本综述讨论了在缺血性脑卒中治疗中使用纳米粒子的潜在益处和现有挑战,为设计有效的纳米粒子以增强缺血性脑卒中治疗效果提供了新的视角。
