Abstract

Inflammation plays a critical role in conditions such as acute liver failure, acute-on-chronic liver failure, and ischemia-reperfusion-induced liver injury. Various pathogenic pathways contribute to liver inflammation, involving inflammatory polarization of macrophages and Küpffer cells, neutrophil infiltration, dysregulation of T cell subsets, oxidative stress, and activation of hepatic stellate cells. While mesenchymal stromal cells (MSCs) have demonstrated beneficial properties, their clinical translation is limited by their cellular nature. However, MSC-derived extracellular vesicles (MSC-EVs) have emerged as a promising cell-free therapeutic approach for immunomodulation. MSC-EVs naturally mirror their parental cell properties, overcoming the limitations associated with the use of MSCs. In vitro and in vivo preclinical studies have demonstrated that MSC-EVs replicate the beneficial effects of MSCs in liver injury. This includes the reduction of cell death and oxidative stress, improvement of hepatocyte function, induction of immunomodulatory effects, and mitigation of cytokine storm. Nevertheless, MSC-EVs face challenges regarding the necessity of defining consistent isolation methods, optimizing MSCs culture conditions, and establishing quality control measures for EV characterization and functional assessment. By establishing standardized protocols, guidelines, and affordable cost mass production, clinicians and researchers will have a solid foundation to conduct further studies, validate the therapeutic efficacy of MSC-EVs, and ultimately pave the way for their clinical implementation in acute liver injury.

摘要

炎症在急性肝衰竭、慢加急性肝衰竭和缺血再灌注诱导的肝损伤等疾病中起着关键作用。多种致病途径导致肝脏炎症,涉及巨噬细胞和库普弗细胞的炎症极化、中性粒细胞浸润、T 细胞亚群失调、氧化应激和肝星状细胞激活。间充质基质细胞(MSCs)具有有益的特性,但由于其细胞性质,其临床转化受到限制。然而,MSC 衍生的细胞外囊泡(MSC-EVs)作为一种有前途的无细胞免疫调节治疗方法已经出现。MSC-EVs 天然地反映了其亲代细胞的特性,克服了使用 MSCs 相关的限制。体外和体内临床前研究表明,MSC-EVs 复制了 MSCs 在肝损伤中的有益作用。这包括减少细胞死亡和氧化应激、改善肝细胞功能、诱导免疫调节作用和减轻细胞因子风暴。然而,MSC-EVs 在定义一致的分离方法、优化 MSC 培养条件以及建立 EV 特征和功能评估的质量控制措施方面面临挑战。通过建立标准化的方案、指南和可负担的大规模生产,临床医生和研究人员将有一个坚实的基础来进行进一步的研究,验证 MSC-EVs 的治疗效果,并最终为其在急性肝损伤中的临床应用铺平道路。
