Exosomes为起源于多泡体的非细胞成分,可来源于DC、B细胞、肿瘤细胞等多种类型。Exosomes浓缩了整套自身来源细胞的抗原成分,含有与自身细胞特殊功能相关的蛋白,具有体积小、易被机体清除、抗原性弱、稳定高效、可控性强等DC疫苗和自体肿瘤疫苗不可比拟的优势,有望成为一种新型肿瘤生物治疗载体。 Exosomes are non-cellular components that originate in multivessels and can be derived from various types of DCs, B cells, tumor cells, and the like. Exosomes concentrate the antigenic components of the whole set of cells of its own origin and contain proteins related to the special functions of its own cells. It is small, easily cleared by the body, weakly antigenic, stable and efficient, and highly controllable. DC vaccine and autologous tumor vaccine are incomparable The advantage is expected to become a new carrier of tumor biological therapy.
