摘要
细胞外囊泡(EVs)是由细胞释放的具有双层脂膜的纳米颗粒,已被证明可以调节生物活性。新兴研究已经发现,EVs 具有作为新型治疗或给药平台的潜力。EVs 的疗效取决于靶细胞内化 EVs 的数量,这就要求增强 EVs 在靶器官中的滞留。因此,人们开发了各种新型给药策略,将治疗性 EVs 靶向输送到特定组织。本综述全面概述了针对脑、心脏、肺、皮肤、眼睛和胃肠道等特定应用的 EV 给药途径的最新进展。我们相信,创新性 EV 给药策略的出现将有助于未来的临床试验和基于 EV 的疗法的最终应用。
Novel administration strategies for tissue-specific delivery of extracellular vesicles
Extracellular vesicles (EVs) are nanoparticles released by cells with bilayer lipid membranes that have been demonstrated to regulate biological activities. The potential of EVs as a novel therapeutic or drug delivery platform has already been identified in emerging research. The therapeutic efficacy of EVs is contingent upon the quantity of EVs internalized by target cells, which necessitates the enhanced retention of EVs in target organs. Accordingly, various novel administration strategies for the targeted delivery of therapeutic EVs into specific tissues were developed. This review presents a comprehensive overview of the latest developments in EV delivery routes for brain-, heart-, lung-, skin-, eye-, and gastrointestinal tract-specific applications. We believe that the emergence of innovative EV administration strategies will contribute to the future clinical trials and eventual applicability of EV-based therapeutics.
