They contain a variety of specific microRNAs (miRNAs) and signaling molecules, and have important research value in tumorigenesis, tumor diagnostic classification and immunotherapy. The effect of exosomes on tumorigenesis is a doubleedged sword, and the miRNAs act as molecular markers and contribute to classify morphologically intractable tumors such as glioblastoma. In antineoplastic therapy, exosomes can be used as drug carriers or induce a new type of immunotherapy through their own characteristics.
