Ular Science, La Trobe University, Bundoora, AustraliaIntroduction: The prospective of utilizing exosomes (endosomal derived vesicles) as a therapeutic delivery program of biological and chemical drugs are an active location of clinical phase investigation. Nonetheless, the field is currently facing challenges such as the insufficient release of exosomes, their heterogeneity and reproducibility of isolation. These troubles may well be overcome by way of the improvement of artificial extracellular vesicles (EVs). Cell-derived mimetic nanovesicles (M-NVs) is usually generated from quite a few cell lines with benefits for example, reproducibility, big scale production, uniformity, price effectiveness as well as a uncomplicated purification system. While various studies have shown that M-NVs have comparable morphology, size and therapeutic possible to exosomes, comprehensive characterization and to what extent these artificial EV elements mimics exosomes stay elusive. Methods: Within this study, M-NVs generated by subjecting cells for the extrusion, were comprehensively characterized and compared to the exosomes by proteomic and transcriptomic evaluation. Benefits: We analysed the proteome amongst M-NVs and exosomes to provide essential insights into important membrane surface attributes of exosomes for cargo sorting and therapeutics delivery are preserved in M-NVs (158 proteins). Additionally, our study highlighted differences in protein post-translational modifications amongst M-NVs, as distinct from exosomes, employing a non-targeted informatic method, specifically displaying phosphorylation, ubiquitination, and thiophosphorylation as enriched protein modifications in M-NVs. Compact RNA evaluation reveals that unlike exosomes, the RNA cargo of M-NVs is similar to that in the parental cells. Also, we discovered that M-NVs might be useful for packaging proteins or RNA which are globally enriched in cells. Certainly, this may perhaps overcome the challenges involved in selective packaging of therapeutic proteins or RNAs into exosomes.JOURNAL OF EXTRACELLULAR VESICLESSummary/Conclusion: In summary, outcomes from this study provides important insights into omics of M-NVs cargo in comparison to exosomes and eventually its prospective as therapeutic delivery method.
