【 摘 要 】

Exosomes are small membrane vesicles of endocytic origin secreted by most cell types. They play important roles in intercellular communications and many physiological processes. DCs-derived exosomes can prime naïve T cells and activate NK cells to shrink the tumor. Tumor-derived exosomes carry a variety of tumor antigens that trigger the robust tumor antigen-specific immune response. Tumor-derived exosomes also contain metastasis or invasive-related molecules, which maybe potential targets for cancer immunotherapy. Effector T cells-derived exosomes possess cytotoxic activity of their original cells, thus cause tumor cells lysis. In this review, we summarized the recent advances on the biogenesis and composition of exosomes, the functions of anti-tumor immune response, and the promising applications on cancer immunotherapy of exosomes from different origins. Exosomes schlep efficient targets homing to tumor sites and tend to be a promising new tool of immunotherapy to fight cancer in a cell-free system.
