Tumor-derived exosomes in the cancer immune microenvironment and cancer immunotherapy

Tumor-derived exosomes (TDEs) are key immune regulators in the tumor microenvironment. They have been shown to reshape the immune microenvironment and prevent antitumor immune responses via their immuno-suppressive cargo, thereby determining responsiveness to cancer therapy. By delivering suppressive cargo to the immune cells, TDEs directly or indirectly influence the functions and antitumor activities of immune cells. TDE-based therapy is emerging as a cutting-edge and promising strategy for inhibiting tumor progression or enhancing antitumor immunity. Therefore, in this study, we reviewed the mechanism by which TDEs regulate immune cells and their applications in immunotherapy.

Automated summary

Tumor-derived exosomes (TDEs) play a critical role in regulating the immune microenvironment of tumors and have the ability to suppress immune responses, thus impacting the effectiveness of cancer therapy. By delivering suppressive factors to immune cells, TDEs directly or indirectly influence immune cell function and antitumor activities. TDE-based therapy is emerging as a promising strategy for inhibiting tumor progression and enhancing antitumor immunity.
