胞外体是真核细胞释放的,含有多种细胞膜分子以及相关蛋白的小囊泡。系由细胞内的多泡体(multivesicular bodies,MVBs)膜与细胞膜融合后释放到细胞外环境中囊泡状结构,被称之为胞外体(exosome,EXO)。多种类型细胞均能以这种胞外分泌的方式释放EXO。抗原提呈细胞(APC),如树突状?
Extracellular bodies are eukaryotic cells that contain a variety of cell membrane molecules and related vesicles. It is a kind of vesicular structure released from the membrane of multivesicular bodies (MVBs) into the extracellular environment, which is called as exosome (EXO). Many types of cells release EXO in this extracellular manner. Antigen-presenting cells (APC), such as dendritic?
