Abstract

Skeletal muscle regeneration entails a multifaceted process marked by distinct phases, encompassing inflammation, regeneration, and remodeling. The coordination of these phases hinges upon precise intercellular communication orchestrated by diverse cell types and signaling molecules. Recent focus has turned towards extracellular vesicles (EVs), particularly small EVs, as pivotal mediators facilitating intercellular communication throughout muscle regeneration. Notably, injured muscle provokes the release of EVs originating from myofibers and various cell types, including mesenchymal stem cells, satellite cells, and immune cells such as M2 macrophages, which exhibit anti-inflammatory and promyogenic properties. EVs harbor a specific cargo comprising functional proteins, lipids, and nucleic acids, including microRNAs (miRNAs), which intricately regulate gene expression in target cells and activate downstream pathways crucial for skeletal muscle homeostasis and repair. Furthermore, EVs foster angiogenesis, muscle reinnervation, and extracellular matrix remodeling, thereby modulating the tissue microenvironment and promoting effective tissue regeneration. This review consolidates the current understanding on EVs released by cells and damaged tissues throughout various phases of muscle regeneration with a focus on EV cargo, providing new insights on potential therapeutic interventions to mitigate muscle-related pathologies.

摘要

骨骼肌再生需要一个多方面的过程,其特征是具有不同的阶段,包括炎症、再生和重塑。这些阶段的协调取决于不同细胞类型和信号分子协调的精确细胞间通讯。最近的研究重点转向了细胞外囊泡(EVs),特别是小细胞外囊泡,作为促进肌肉再生过程中细胞间通讯的关键介质。值得注意的是,受损的肌肉会引发源自肌纤维和各种细胞类型(包括间充质干细胞、卫星细胞和 M2 巨噬细胞等免疫细胞)的 EV 的释放,这些 EV 具有抗炎和促生成特性。EV 携带特定的货物,包括功能性蛋白质、脂质和核酸,如 microRNAs(miRNAs),它们在靶细胞中精细地调节基因表达,并激活对骨骼肌肉稳态和修复至关重要的下游途径。此外,EV 促进血管生成、肌肉再神经支配和细胞外基质重塑,从而调节组织微环境并促进有效的组织再生。本综述总结了细胞和受损组织在肌肉再生的各个阶段释放的 EV 的当前理解,重点介绍了 EV 货物,为减轻与肌肉相关的病理提供了新的治疗干预见解。
