Extracellular vesicles (EVs) derived from tumors play a pivotal role in cancer therapy, particularly in modulating immune responses and tumor microenvironments. A study demonstrated that tumor-derived extracellular vesicles (TEVs) often express immuno-evasive ligands like CD47, which inhibit phagocytosis by dendritic cells and macrophages, thereby facilitating tumor survival (ref: Ding doi.org/10.1038/s41565-024-01783-2/). This finding underscores the importance of engineering TEVs to mask these ligands, enhancing the efficacy of tumor vaccination strategies. Additionally, research revealed that EVs containing acyl-CoA synthetase long-chain family member 4 (ACSL4) from hepatocellular carcinoma cells can induce senescence in hepatocytes, promoting a tumor-supportive microenvironment (ref: Hou doi.org/10.1158/0008-5472.CAN-24-0832/). Furthermore, melanoma-derived EVs were shown to convert normal dermal fibroblasts into carcinoma-associated fibroblasts through miR-92b-3p-mediated PTEN downregulation, highlighting the role of EVs in tumor progression (ref: Kewitz-Hempel doi.org/10.1002/jev2.12509/). These studies collectively illustrate the dual role of EVs in both promoting tumor growth and serving as potential therapeutic targets in cancer treatment. Moreover, engineered EVs containing MAP kinase kinase 1 (MEK1) have been shown to enhance anti-tumor immunity, suggesting a promising avenue for future immunotherapeutic strategies (ref: Searles doi.org/10.1002/jev2.12515/).

Extracellular vesicles (EVs) are increasingly recognized for their role in immune modulation, particularly in the context of exercise and inflammation.

Collectively, these findings underscore the importance of EVs in disease diagnostics and the need for further exploration of their biomarker potential.

Understanding the mechanisms by which extracellular vesicles (EVs) exert their functions is critical for harnessing their therapeutic potential. Recent research has focused on the role of EVs in drug delivery and immune modulation.
