New roles of tumor-derived exosomes in tumor microenvironment

引用

Chinese Journal of Cancer Research 2024年第2期36卷 151-166页

作者： Shiqian Chen Jinzhe Sun Huan Zhou Hongbin Lei Dan Zang Jun Chen department of Oncology the Second Hospital of Dalian Medical UniversityDalian 116023China department of Radiotherapy the Second Hospital of Dalian Medical UniversityDalian 116023China

Throughout tumorigenesis, the co-evolution of tumor cells and their surrounding microenvironment leads to the development of malignant phenotypes. Cellular communication within the tumor microenvironment(TME) plays a critical role in influencing various aspects of tumor progression, including invasion and metastasis. The release of exosomes, a type of extracellular vesicle, by most cell types in the body, is an essential mediator of intercellular communication. A growing body of research indicates that tumor-derived exosomes(TDEs) significantly expedite tumor progression through multiple mechanisms, inducing epithelial-mesenchymal transition and macrophage polarization, enhancing angiogenesis, and aiding in the immune evasion of tumor cells. Herein, we describe the formation and characteristics of the TME, and summarize the contents of TDEs and their diverse functions in modulating tumor development. Furthermore, we explore potential applications of TDEs in tumor diagnosis and treatment.
