Progress in mechanism of tumor-derived exosomes on myeloid-derived suppressor cells / 中华微生物学和免疫学杂志

ABSTRACT

Myeloid-derived suppressor cells (MDSCs) play an important immunosuppressive role in the tumor microenvironment. Tumor cells can regulate the immunosuppressive function of MDSCs in the tumor microenvironment through exosomes, thereby affecting the development of tumors. Tumor-derived exosomes (TEXs) promote the development of MDSCs and improve their immunosuppressive function in the tumor microenvironment mainly by participating in the processes such as intercellular information exchange and information transmission. Moreover, the miRNAs in TEXs will also be transferred to recipient cells to inhibit the immunosuppressive function of MDSCs by inducing the negative regulation of target genes. This review summarized the progress in the mechanism of TEXs on MDSCs.
