The tumor microenvironment (TME) of GBM is very complex and includes various cell types, such as immune cells, endothelial cells, astrocytes, and microglia. The TME plays a crucial role in the development of GBM and its resistance to therapy. One important part of the TME is extracellular vesicles (EVs), which help cells communicate and contribute to different aspects of GBM progression. They help the tumor grow and spread by increasing cellular proliferation, invasion, and survival. They also play a key role in angiogenesis by transferring pro-angiogenic factors to endothelial cells, which help form new blood vessels that provide the tumor with essential nutrients and oxygen. Within the context of immune modulation, EVs derived from GBM cells contain immunosuppressive molecules that alter the function of immune cells in the TME, enabling the tumor to escape immune surveillance. This immunosuppressive environment is marked by elevated levels of regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSCs), and tumor-associated macrophages (TAMs). Furthermore, EVs contribute to therapeutic resistance by transferring drug-resistance factors from resistant to sensitive tumor cells, enhancing their capacity to withstand chemotherapy and radiotherapy. The RNA cargo of EVs, which includes microRNAs and long non-coding RNAs, plays a crucial role in modulating gene expression and cellular responses to treatment. In conclusion, EVs are vital in the development and progression of GBM by influencing angiogenesis, immune modulation, and therapeutic resistance. Targeting EV-mediated communication presents a promising therapeutic strategy for addressing the challenges posed by this deadly brain tumor.</div></div>","PeriodicalId":73007,"journal":{"name":"Extracellular vesicle","volume":"5 ","pages":"Article 100075"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While techniques for isolating sEV from large body fluids auch as blood and urine are relatively well-developed, isolating sEV from solid organs remains challenging. This is because the preparations are often seen contaminated with <em>intracellular</em> vesicles due to cell breakage resulting from the treatments used to release sEV from the extracellular matrix. Here, we introduce a new gentle method that allows for the reliable isolation of sEV from heart and liver tissues with high purity and yield. The protocol involves an initial treatment of tissues with selected collagenase, followed by consecutive differential centrifugation and density-gradient ultracentrifugation to separate sEV from cells and large EV (lEV), and further density-gradient ultracentrifugation to fractionate sEV subpopulations. Characterization of the preparations reveals markedly enhanced cellular survival and reduced co-purification of extracellular non-vesicular particles as well as subcellular organelles. Moreover, we found that sEV isolated from heart, liver, and plasma are similar in morphology and size, but differ in density and protein marker distributions among sEV subpopulations.

Biodistribution studies reveal tIL-10 presence in placental and fetal membranes within 5 min, persisting for up to 3 h.
