Stroke is a major cause of death and disability worldwide that triggers a variety of neuropathological conditions, leading to the initiation of several pro-inflammatory mediators and neuronal damage. Neuroinflammation has been considered the potential therapeutic target and contributes to the pathology of ischemia and reperfusion. Pyroptosis is an inflammatory form of programmed cell death that plays an important role in immune protection against stroke. Gasdermin D (GSDMD) is the final executor of pyroptosis upon cleavage by caspases-1/4/5/11, followed by canonical and noncanonical inflammasome activation, leading to a series of inflammatory responses. GSDMD N-terminal domain assembles plasma membrane as well as organelle membrane pores to induce cytolysis, thereby triggering cytokine release and inflammatory-related cell death. In our review, we concisely summarized and highlighted the potential role of GSDMD-regulated pyroptosis and the biological characteristic of GSDMD as a therapeutic target in ischemic stroke. A better understanding of the roles of GSDMD may provide a theoretical basis for the design of novel therapeutic interventions for the treatment of ischemic stroke.
中风是全球范围内主要的死亡和残疾原因,可引发多种神经病理学状况,导致多种促炎介质的启动和神经元损伤。神经炎症已被认为是潜在的治疗靶点,并导致了缺血和再灌注的病理过程。细胞焦亡是一种炎症形式的程序性细胞死亡,在针对中风的免疫保护中发挥着重要作用。Gasdermin D(GSDMD)是被半胱天冬酶-1/4/5/11 切割后细胞焦亡的最终执行者,随后引发经典和非经典炎性小体的激活,导致一系列炎症反应。GSDMD N 端结构域组装质膜和细胞器膜孔,诱导细胞裂解,从而引发细胞因子释放和炎症相关细胞死亡。在本综述中,我们简要总结并强调了 GSDMD 调节的细胞焦亡的潜在作用以及 GSDMD 作为缺血性中风治疗靶点的生物学特征。更好地理解 GSDMD 的作用可能为设计新型治疗干预缺血性中风的治疗提供理论基础。
