摘要:

星形胶质细胞是中枢神经系统中最丰富的神经胶质细胞,可参与维持大脑结构和调节神经系统功能的重要生物过程。外泌体是细胞来源的细胞外囊泡,含有从细胞分泌的各种生物活性分子,如蛋白、多肽、核苷酸和脂质。越来越多的证据表明,外泌体在神经系统中构成了一个通信网络,而星形胶质细胞来源的外泌体在此网络中发挥着重要的作用。此次综述总结了靶向星形胶质细胞的外泌体,以及星形胶质细胞来源的靶向其他类型细胞的外泌体的作用,并对基于外泌体的通信网络的潜在研究方向进行展望。这项综述得出以星形胶质细胞为重点的基于外泌体的细胞间通信对大脑不同条件下的生物学或病理过程具有重要意义。

Abstract: Astrocytes are the most abundant glial cells in the central nervous system; they participate in crucial biological processes, maintain brain structure, and regulate nervous system function. Exosomes are cell-derived extracellular vesicles containing various bioactive molecules including proteins, peptides, nucleotides, and lipids secreted from their cellular sources. Increasing evidence shows that exosomes participate in a communication network in the nervous system, in which astrocyte-derived exosomes play important roles. In this review, we have summarized the effects of exosomes targeting astrocytes and the astrocyte-derived exosomes targeting other cell types in the central nervous system. We also discuss the potential research directions of the exosome-based communication network in the nervous system. The exosome-based intercellular communication focused on astrocytes is of great significance to the biological and/or pathological processes in different conditions in the brain. New strategies may be developed for the diagnosis and treatment of neurological disorders by focusing on astrocytes as the central cells and utilizing exosomes as communication mediators.

Key words: astrocytes, communication, exosomes, neurological disorders, targeting mechanism
