Cancer is more than just a group of rapidly growing cells, it’s a complex environment where tumor cells talk to each other and their surroundings. A major way they do this is through tiny packages called extracellular vesicles (EVs). These are nano-sized particles released by both cancer cells and nearby non-cancerous cells. They carry important cargo like proteins, RNA, and fats that help send signals between cells.
In a recent review published in Molecular Cancer, researchers from the Czech Academy of Sciences, dive deep into how EVs play a key role in cancer. These vesicles can promote tumor growth by helping cancer cells build new blood vessels (angiogenesis), spread to other parts of the body (metastasis), and hide from the immune system (immune evasion). What’s more, they can carry special molecules that researchers might be able to detect in blood samples, making them useful for liquid biopsies, a promising alternative to more invasive diagnostic procedures.

EVs mediate multiple immunosuppressive mechanisms that collectively contribute to tumor immune evasion, promoting angiogenesis, tumor growth, and metastasis, thereby highlighting the crucial role of EVs in shaping the immunosuppressive tumor microenvironment.

The review also explores how EVs could be turned into tools for treatment. Since they are naturally good at delivering messages between cells, scientists are looking at how EVs might be used to carry drugs directly to cancer cells or help train the immune system to fight tumors more effectively.
By understanding how these vesicles work, scientists hope to create more personalized and precise cancer treatments that improve outcomes and reduce side effects.
