Extracellular vesicles (EVs) are lipid membrane vesicles released by cells. They carry active biomolecules including DNA, RNA, and protein which can be transferred to recipient cells. Isolation and purification of EVs from culture cell media and biofluids is still a ...

Extracellular vesicles (EVs) are cell-derived vesicles generated through a process of cell membrane shedding or storage vesicle release, as occurs during apoptosis, necrosis or exocytosis. Initially perceived as cellular by-products or ‘dust’ of insignificant biological importance, recent research has shed ...

Proteomic studies of circulating vesicles are hampered by difficulties in purifying vesicles from plasma and serum. Isolations are contaminated with high-abundance blood proteins that may mask genuine vesicular-associated proteins and/or simply provide misleading data. In this brief report, we explored ...

Lung cancer is one of the leading causes of cancer-related death. At the time of diagnosis, more than half of the patients will have disseminated disease and, yet, diagnosing can be challenging. New methods are desired to improve the diagnostic ...

Exosomes have proven roles in regulating immune response, antigen presentation, RNA and protein transfer, and cell-cell (organ-organ) interaction/signaling. These microvesicles can be considered a mechanism of non-classical secretion of proteins, and they represent a subproteome, thus assisting in the difficult ...

Human placenta releases specific nanovesicles (i.e. exosomes) into the maternal circulation during pregnancy, however, the presence of placenta-derived exosomes in maternal blood during early pregnancy remains to be established. The aim of this study was to characterize gestational age related ...

Exosomes are membrane-bound vesicles found in all biological fluids. AML patients’ plasma collected at diagnosis contains elevated exosome levels relative to normal donor (ND) plasma. The molecular profile of AML exosomes changes in the course of therapy and may serve ...

Microparticles (MPs) and exosomes are released by cells using different mechanisms. Thus, quantitative as well as qualitative changes of both particle populations, MPs and exosomes, in patients with coronary artery disease (CAD) might reflect an altered activation status of the ...

Extracellular α-synuclein is important in the pathogenesis of Parkinson’s disease (PD) and also as a potential biomarker when tested in the cerebrospinal fluid (CSF). The performance of blood plasma or serum α-synuclein as a biomarker has been found to be ...

A major but hitherto overseen component of the blood/plasma secretome is that of extracellular vesicles (EVs) which are shed from all blood cell types. These EVs are made up of microvesicles (MVs) and exosomes. MVs, 100nm-1μm in diameter, are released ...
