    摘要:

    质膜(PM)在维持细胞稳态方面发挥着至关重要的作用。因此,及时有效地修复由于机械破裂、孔形成毒素或孔形成蛋白等原因造成的质膜损伤对细胞存活至关重要。质膜损伤会导致细胞膜破裂并刺激免疫反应。然而,由程序性细胞死亡过程(如焦亡、铁死亡和坏死性凋亡)引起的质膜损伤不能通过简单的封闭机制修复,因此需要专门的修复机制。最新研究揭示了一种由内泡运输所需的排序复合体(ESCRT)机制介导的质膜损伤修复机制。本文回顾了ESCRT机制介导的质膜损伤修复机制的研究进展,特别关注与程序性细胞死亡相关的过程。本综述以及该领域的持续工作可以为治疗由程序性细胞死亡途径失调引起的疾病提供新的见解。

    Abstract:

    The plasma membrane (PM) plays an essential role in maintaining cell homeostasis, therefore, timely and effective repair of damage caused by factors such as mechanical rupture, pore-forming toxins, or pore-forming proteins is crucial for cell survival. PM damage induces membrane rupture and stimulates an immune response. However, damage resulting from regulated cell death processes, including pyroptosis, ferroptosis, and necroptosis, cannot be repaired by simple sealing mechanisms and thus, requires specialized repair machinery. Recent research has identified a PM repair mechanism of regulated cell death-related injury, mediated by the endosomal sorting complexes required for transport (ESCRT) machinery. Here, we review recent progress in elucidating the ESCRT machinery-mediated repair mechanism of PM injury, with particular focus on processes related to regulated cell death. This overview, along with continued research in this field, may provide novel insights into therapeutic targets for diseases associated with dysregulation of regulated cell death pathways.
