Valiente M, Obenauf AC, Jin X, et al. Fluids Barriers CNS. Tumor cell-derived exosomes usually carry important signal molecules, such as miRNA, which can reshape the tumor microenvironment by regulating immune response and angiogenesis, thus participating in the metastasis of tumor cells [13]. Astrocytes participate in almost all the functions of the CNS starting from the development and its role in providing structural and functional support for neurons and for maintaining the physical barrier between the blood and brain interface with the support of endothelial cells.

Fong and his colleagues demonstrated that uptake of miR-122-containing exosomes secreted by breast cancer cells leads to decreased expression of PKM2 and GLUT1 in astrocytes and reduced glucose ingestion [32]. showed that the exosomes derived from breast cancer cells could transfer miR-181c to brain endothelial cells and change the expression of tight junction proteins as well as the position of actin filaments, thereby disrupting the tight junction between endothelial cells and leading to increased BBB permeability [14].
