Exosomes as therapeutic solutions for pancreatic cancer

Download Type: External Link

Exosomes promote progression and metastasis in pancreatic cancer (PC). Exosomes promote chemoresistance in PC. Exosomes carry signals between PC cells and its surrounding microenvironment cells. Exosomes can be used as biomarkers or targets for PC management.

 Pancreatic cancer (PC) is one the deadliest cancers worldwide. It is characterized by elevated mortality rates because of the lack of effective diagnostic methods, the dense stroma that shields the tumor from effective drug penetration, and the emergence of chemoresistance. Recent research has elucidated the role of PC-derived exosomes in driving and fueling PC progression, metastasis, and chemoresistance by transporting key molecules from tumor cells to recipient cells in the tumor microenvironment (TME). In this review, we delineate some of the key exosomal molecules involved in immune suppression and reprogramming of the TME, the establishment of metastatic niches, and drug resistance. We also explore the potential of exosomes as both diagnostic tools for early PC detection and management and as therapeutic targets.
