Notably, chemical or genetic modifications to the surface of EVs can further strengthen their targeting ability. These advancements not only improve the specificity of RNA therapies but also address the challenges of RNA delivery associated with traditional methods.

This study explores the potential of arrestin domain-containing protein 1 (ARRDC1)-mediated microvesicles (ARMMs)—a type of extracellular vesicles formed at the plasma membrane—as a novel platform for packaging and delivering CRISPR-Cas9 complexes. We achieved efficient Cas9 packaging into ARMMs by directly fusing Cas9 with ARRDC1. Two different ARRDC1-Cas9 fusion constructs were designed, and both demonstrated gene-editing efficiency comparable to unmodified Cas9. The fusion with a shorter version of ARRDC1 (sARRDC1), which includes only the minimal motifs required for vesicle budding, proved particularly effective in enhancing Cas9 packaging. Additionally, the incorporation of vesicular stomatitis virus glycoprotein (VSV-G) further improved ARMMs budding and Cas9 encapsulation. We tested gene editing in U2OS cells with an exogenous GFP gene and in human neuronal cells targeting the endogenous amyloid precursor protein (APP) gene, which is associated with the Alzheimer's disease. The combination of ARMMs and VSV-G resulted in high editing efficiency, with ARMMs targeting the APP gene in neuronal cells significantly reducing pathogenic amyloid peptides. These results highlight ARMMs as a versatile and effective platform for CRISPR-Cas9 delivery, with strong potential for therapeutic applications in neurodegenerative and other genetic diseases.</div></div>","PeriodicalId":73007,"journal":{"name":"Extracellular vesicle","volume":"5 ","pages":"Article 100082"},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143927767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent advancements in exosome biology have unveiled their crucial role in cell signaling and paracrine-mediated functions. In this article, we will highlight the concept of exofection. In this well-defined donor-recipient relationship, donor cells produce specific biomolecules encapsulated within exosomes, which are then delivered to recipient cells. This process is particularly crucial when recipient cells experience functional deficiencies due to physiological or pathological conditions. Upon receiving the exosomal cargo, recipient cells transiently express and exhibit the functional activity of the delivered molecules. The functional enhancement mediated by exofection is transient, gradually diminishing once the delivery from the donor cells declines, and the recipient cell no longer needs specific function. Utilizing studies from various fields, we highlight the diverse biological contexts in which exofection operates. For instance, mitochondria-containing EVs from brain endothelial cells restore mitochondrial function and tight junction integrity in ischemic brain tissues. In contrast, exosomes from TNF-α-preconditioned mesenchymal stromal cells regulate autophagy and inflammation in acute pancreatitis. Similarly, Th2 cell-derived EVs promote eosinophil survival during airway inflammation, and umbilical cord blood exosomes accelerate wound healing by enhancing angiogenesis and fibroblast function. The role of exosomes in complex pathophysiological contexts such as myocardial infarction, glioblastoma, and liver failure can be crucial. In each scenario, the donor cells' exosomal cargo modulates recipient cell functions, promoting tissue repair, immune regulation, or metastasis. This work expands the conceptual framework of exofection and emphasizes its potential impact on therapeutic development and understanding the pathophysiology of various diseases.</div></div>","PeriodicalId":73007,"journal":{"name":"Extracellular vesicle","volume":"5 ","pages":"Article 100081"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we compared four methods for suEV isolation, including ultracentrifugation (UC), ultracentrifugation with DTT treatment (DTT + UC), filtration and ultracentrifugation (F + UC), and filtration and ultrafiltration (F + UF). We evaluated their recovery, EV purity, and proteomic coverage using multiple techniques. The combination of filtration and ultracentrifugation (F + UC) showed the best performance with efficient removal of uromodulin fibers and successful in-depth proteome identification. Furthermore, we performed a deep-going proteomic analysis and characterized suEV subsets purified by the four methods. Lastly, we developed a statistical approach to evaluate universal suEV proteins, independent of the isolation techniques used, by calculating the correlation between protein abundance and sample purity.
