Small extracellular vesicles (sEVs) are released by cells into various biological fluids, providing a window to ascertain the cellular status of the source cells. Although many aspects of sEV biology are still enigmatic, analysis of sEV contents in biofluids offers readouts with broad applications, and may be superior or complementary to other assays of liquid biopsy. sEVs carry cell-derived biomaterials, including nucleic acids, proteins, lipids, and metabolites. RNAs are dominant components packed in sEVs, consisting of various biotypes. Protected by the phospholipid bilayer outer membrane of the sEVs, sEV RNAs are remarkably stable. Therefore, the RNA cargos originated from the cancer cells might have high potential as biomarkers in analysis of oncological features. This review will (1) characterize the RNA species loaded into sEVs as well as the related RNA metabolism; (2) summarize the molecular mechanisms of RNA sorting into sEVs, and (3) discuss the potential of using liquid biopsy of sEV RNAs in oncology for early diagnosis of tumor, assessment of tumor burden, response to therapy and monitoring minimal residual disease for recurrence and disease progression.</p></div>","PeriodicalId":73007,"journal":{"name":"Extracellular vesicle","volume":"1 ","pages":"Article 100015"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773041722000105/pdfft?md5=c7e3c8140ad3c669eaf9324e681432da&pid=1-s2.0-S2773041722000105-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43268004","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}

However, due to the immunosuppressive effects of the tumor microenvironment, it is still hard to activate T cells in situ. Especially, antigen-specific T cell activity is further limited as tumor cells can evade T cell attack via PD-1/PD-L1 axis. During this work, we used a dendritic cells (DCs)-derivate exosome vaccine to build an immunotherapeutic system that can simultaneously mediate antigenic T cell activity by carrying T cells activating CD80 and MHC to induce humoral immunity. More importantly, in order to interrupt tumor immune escape, we also engineered anti-PD-L1 antibodies (aPD-L1) to block PD-1/PD-L1 axis at the same time. Our antigens-feeding DCs-exosomes with aPD-L1 engineering represents a promising strategy for enhanced cancer immunotherapy by robust activating T cells. The outcomes demonstrated that Exo-OVA-aPD-L1 was successful in inhibiting the growth, recurrence, and metastasis of melanoma.</p></div>","PeriodicalId":73007,"journal":{"name":"Extracellular vesicle","volume":"1 ","pages":"Article 100012"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773041722000075/pdfft?md5=f8857c50cc77e4b859d5feff22fff131&pid=1-s2.0-S2773041722000075-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41261453","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}

However, the mechanisms by which EVs induce tissue repair have not been well demonstrated. Previous work indicates that activation of hepatic stellate cells (HSCs) may contribute to the progression of liver fibrosis. Here, we investigate the therapeutic potential of EVs derived from human placental mesenchymal stem cells (hP-MSCs) for the treatment of carbon tetrachloride (CCl4)-induced liver injury. Our data revealed that EVs derived from hP-MSCs effectively ameliorate liver injury by attenuating inflammation and fibrosis. Further data revealed that heparan sulfate proteoglycans (HSPGs) on the surface of HSCs mediate the internalization of EVs. Furthermore, EVs could inhibit the epithelial–mesenchymal transition (EMT) process in HSCs through the downregulated TGF-<span><math><mi>β</mi></math></span>/Smad pathway, which was mediated by miR-744-5p in EVs. Meanwhile, glycosaminoglycans on the surface of EVs play a crucial anti-inflammatory role. In conclusion, our results provide evidence that hP-MSC-derived EVs promote the recovery of liver injury by targeting HSPGs on HSCs and inhibiting liver inflammation through glycosaminoglycans from EVs. These findings may provide a novel theoretical basis for the treatment of liver fibrosis based on EVs.</p></div>","PeriodicalId":73007,"journal":{"name":"Extracellular vesicle","volume":"1 ","pages":"Article 100018"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773041722000130/pdfft?md5=d75954f4d1b9af37bd48505b0a9c2691&pid=1-s2.0-S2773041722000130-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46753630","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}
