Heterogeneity of Extracellular Vesicles and Non-Vesicular Nanoparticles in Glioblastoma.

ABSTRACT: It is increasingly clear that intercellular communication is largely mediated by lipid-bilayer, membrane-bound extracellular vesicles (EVs) and amembranous, non-vesicular extracellular particles (NVEPs), including exomeres and the recently identified supermeres. To elucidate the cargo and functional roles of these carriers, we performed a comprehensive analysis of their lipid, protein and RNA content in the context of colorectal cancer and glioblastoma (GBM). Our results demonstrate that EVs exhibit distinct density profiles correlated with specific biomolecular signatures. Moreover, EVs and NVEPs display notable differences in their protein and RNA composition, which confer distinct functional attributes. Supermeres are notably enriched in components involved in extracellular matrix remod
