Abstract
세포외소포체는 세포 유래 소포로 진보된 약물 전달 시스템에 사용될 수 있다. 세포외소포체는 전구체 세포의 세포막이 지닌 핵심 특성을 보유할 수 있다. 이 특성은 표적 세포에 의한 효율적인 세포 흡수를 가능하게 한다. 또한, 대부분의 암세포로부터 유래한 세포외소포체는 망상내피계 (RES) 제거율을 낮출 수 있는 인테그린-관련 막 관통 단백질 CD47을 함유한다. 그러나, 세포외소포체는 약물 봉입 효율이 낮다는 한계가 있다. 대조적으로, 리포솜은 약물 전달 시스템으로서 몇 가지 장점이 있지만, 암세포 내에서 세포 흡수가 제한될 뿐 아니라, RES 제거율 증가의 문제도 발생한다. 따라서, 세포외소포체와 리포솜이 융합된 새로운 약물 전달 시스템을 개발하는 연구를 수행했다. Adenocarcinomic human alveolar basal epithelial cell (A549)에서 분리된 세포외소포체의 CD47 특성을 이용, RES 제거율을 낮춘 새로운 약물 전달 시스템은 세포외소포체와 리포솜이 가진 단점을 상호 보완해 강화된 항암효과를 기대할 수 있다.|Extracellular Vesicles are cells derived vesicles that can be used for advanced drug delivery system. Extracellular Vesicles (EVs) can preserve key features from the cell membrane of their precursor cells. This property is responsible for an efficient cellular uptake by target cells. Again, EVs from most of the cancer cells contain integrin-associated transmembrane protein CD47 which can lower reticuloendothelial system (RES) clearance. However, EVs have limitations of low drug loading efficiency. In contrast, liposomes have several advantages as delivery system, but they have limited cellular uptake within cancer cells and also suffer from increased RES clearance. Thus, we are trying to develop a novel delivery system by fusing EVs and liposomes as well as exploit the CD47 properties of EVs isolated from adenocarcinomic human alveolar basal epithelial cells, A549 to escape from RES clearance to give enhanced anticancer effects.
