Ischemic stroke is a leading cause of disability and death worldwide, largely due to its increasing incidence associated with an aging population. This condition results from arterial obstruction, significantly affecting patients' quality of life and imposing a substantial economic burden on healthcare systems. While current treatments primarily focus on the rapid restoration of blood flow through thrombolytic therapy or surgical interventions, a limited understanding of neuronal injury mechanisms hampers the development of more effective treatments.This article explores the interplay among various cell death pathways-necroptosis, apoptosis, autophagy, ferroptosis, and pyroptosis-in the context of ischemic stroke to identify novel therapeutic targets. Each mode of cell death displays unique characteristics and roles post-stroke, and the activation of these pathways may vary across different animal models, complicating the translation of therapeutic strategies to clinical settings. Notably, the interaction between apoptosis and necroptosis is highlighted; inhibiting apoptosis might heighten the risk of necroptosis. Therefore, a balanced regulation of these pathways could promote enhanced neuronal survival.Additionally, we introduce PANoptosis, a form of cell death that encompasses pyroptosis, apoptosis, and necroptosis, emphasizing the complexity and potential therapeutic implications of these interactions. In summary, understanding the relationships among these cell death mechanisms in ischemic stroke is vital for developing new neuroprotective agents. Future research should aim for combinatorial interventions targeting multiple pathways to optimize treatment strategies and improve patient outcomes.
缺血性中风是全球致残和致死的主要原因,这在很大程度上归因于其发病率随着人口老龄化而上升。这种疾病是由动脉阻塞引起的,严重影响患者的生活质量,并给医疗系统带来巨大的经济负担。虽然目前的治疗主要集中在通过溶栓治疗或手术干预快速恢复血流,但对神经元损伤机制的了解有限阻碍了更有效治疗方法的开发。本文探讨了在缺血性中风背景下各种细胞死亡途径——坏死性凋亡、细胞凋亡、自噬、铁死亡和焦亡——之间的相互作用,以确定新的治疗靶点。每种细胞死亡模式在中风后都表现出独特的特征和作用,并且这些途径的激活在不同的动物模型中可能有所不同,这使得治疗策略向临床应用的转化变得复杂。值得注意的是,细胞凋亡和坏死性凋亡之间的相互作用被突出强调;抑制细胞凋亡可能会增加坏死性凋亡的风险。因此,对这些途径进行平衡调节可以促进神经元存活率的提高。此外,我们引入了PANoptosis,这是一种包含焦亡、细胞凋亡和坏死性凋亡的细胞死亡形式,强调了这些相互作用的复杂性和潜在的治疗意义。总之,了解缺血性中风中这些细胞死亡机制之间的关系对于开发新的神经保护药物至关重要。未来的研究应旨在针对多种途径进行联合干预,以优化治疗策略并改善患者预后。
