Abstract

Exosomes are nano-sized membrane-bound extracellular vesicles containing various biological molecules, such as nucleic acids, proteins, and lipids, which can be used to modulate physiological processes. The exosomal molecules secreted by cells can be extensively used as tools for diagnosis and therapy. Exosomes carry specific molecules released by the cells they originate from, which can be transferred to surrounding cells or tissues by the exosome. For these reasons, exosomes can be exploited as biomarkers for diagnosis, carriers for drug delivery, as well as therapeutics. In stem cell technology, exosomes have been an attractive option because they can be used as safer therapeutic agents for stem cell-based cell-free therapy. Recently, studies have demonstrated the safety and efficacy of mesenchymal stem cell-derived exosomes in alleviating symptoms associated with coronavirus disease 2019 as they have anti-inflammatory and immunomodulatory potential. Performing multiple studies on exosomes would provide innovative next-generation options for clinical diagnostics and therapy. This review summarizes the use of exosomes focusing on their diverse roles. In addition, the potential of exosomes is illustrated with a focus on how exosomes can be exploited as powerful tools in the days to come.

엑소좀은 나노 크기의 세포외 소포체로 핵산, 단백질, 지질 등 다양한 생리활성 물질을 함유하고 있다. 엑소좀의 생리활성 물질들은 주변 세포나 조직으로 전달될 수 있을 뿐만 아니라 기원된 세포의 고유 특정 물질들을 지니고 있기 때문에 엑소좀 유래 물질들은 진단 및 치료를 위한 도구로 광범위하게 사용될 수 있음이 입증되고 있으며, 이러한 이유로 엑소좀은 진단을 위한 바이오마커, 약물 전달을 위한 운반체 및 치료제로 활용될 수 있는 가능성에 많은 연구자들의 관심이 높아지고 있다. 줄기세포 분야에서 엑소좀은 줄기세포를 기반으로 한 비세포 치료제로서 보다 안전한 치료제로 사용될 수 있다는 점에서 매력적인 소재가 되고 있으며, 최근에는 중간엽줄기세포 유래 엑소좀이 항염증 및 면역조절능이 있어 코로나-19 증상 완화 효능에 대한 안전성과 효능이 입증되기도 했다. 이렇게 계속적인 엑소좀에 대한 축적된 연구는 임상 진단 및 치료를 위한 차세대 혁신적 결과물들을 제공할 것으로 생각되며, 이 종설에서는 엑소좀의 다양한 가치에 초점을 두고 미래의학의 강력한 도구로 어떻게 활용될 수 있는지에 대한 엑소좀의 잠재력을 살펴보고자 한다.
