In the past years, significant clinical advances have been made in the treatment of cancer through the immune system. As a new vaccine method for cancer immunotherapy, AEX shows great potential for the treatment of numerous tumors. The successful development of AEX-based vaccines will further expand the weaponry to battle cancer. In addition to the AEX-based vaccine, tumor cell-derived exosomes (TEX)-based cancer vaccines and dendritic cell-derived exosomes (DEX)-based vaccines have also been developed for immunotherapy.
