摘要

Chemokine CCL5 (RANTES), as a key mediator of intercellular communication in cancers, and its role in cancer development, metastasis and immune escape has received increasing attention. CCL5 and its receptors are important components of the tumor microenvironment and play a tumor promoting role in different ways by triggering signaling pathways through binding to the primary receptor CCR5. CCL5 was viewed as indispensable “gate keepers” of immunity and inflammation, it remains unclear of CCL5-mediated intercellular communication. Therefore, in this review, we summarize the latest information on the origin, structure, and characterization of CCL5 and role of CCL5 in the tumor microenvironment. It includes CCL5-mediated intercellular communication through exosomes, microvesicles and others in breast, lung, and ovarian cancers. CCL5 has a multifaceted role in cancer and has potential applications as a biomarker for cancer diagnosis and prognosis, which provides theoretical bases and therapeutic targets for the development of new cancer therapeutic strategies.
