    Extracellular vesicles (EVs) mediate normal physiological homeostasis and pathological processes by facilitating intercellular communication. Research of EVs in basic science and clinical settings requires both methodological standardization and development of reference materials (RM). Here, we show insights and results of biological RM development for EV studies. We used a three-step approach to find and develop a biological RM. First, a literature search was done to find candidates for biological RMs. Second, a questionnaire was sent to EV researchers querying the preferences for RM and their use. Third, a biological RM was selected, developed, characterized, and evaluated. The responses to the survey demonstrated a clear and recognized need for RM optimized for the calibration of EV measurements. Based on the literature, naturally occurring and produced biological RM, such as virus particles and liposomes, were proposed as RM. However, none of these candidate RMs have properties completely matching those of EVs, such as size and refractive index distribution. Therefore, we evaluated the use of nanoerythrosomes (NanoE), vesicles produced from erythrocytes, as a potential biological RM. The strength of NanoE is their resemblance to EVs. Compared to the erythrocyte-derived EVs (eryEVs), NanoE have similar morphology, a similar refractive index (1.37), larger diameter (70% of the NanoE are over 200nm), and increased positive staining for CD235a and lipids (Di-8-ANEPPS) (58% and 67% in NanoE vs. 21% and 45% in eryEVs, respectively). Altogether, our results highlight the general need to develop and validate new RM with similar physical and biochemical properties as EVs to standardize EV measurements between instruments and laboratories.

  6. [해외논문]   Effect of shear stress in the flow through the sampling needle on concentration of nanovesicles isolated from blood

    초록

    During harvesting of nanovesicles (NVs) from blood, blood cells and other particles in blood are exposed to mechanical forces which may cause activation of platelets, changes of membrane properties, cell deformation and shedding of membrane fragments. We report on the effect of shear forces imposed upon blood samples during the harvesting process, on the concentration of membrane nanovesicles in isolates from blood. Mathematical models of blood flow through the needle during sampling with vacuumtubes and with free flow were constructed, starting from the Navier-Stokes formalism. Blood was modeled as a Newtonian fluid. Work of the shear stress was calculated. In experiments, nanovesicles were isolated by repeated centrifugation (up to 17,570xg) and washing, and counted by flow cytometry. It was found that the concentration of nanovesicles in the isolates positively corresponded with the work by the shear forces in the flow of the sample through the needle. We have enhanced the effect of the shear forces by shaking the samples prior to isolation with glass beads. Imaging of isolates by scanning electron microscopy revealed closed globular structures of a similar size and shape as those obtained from unshaken plasma by repetitive centrifugation and washing. Furthermore, the sizes and shapes of NVs obtained by shaking erythrocytes corresponded to those isolated from shaken platelet-rich plasma and from unshaken platelet rich plasma, and not to those induced in erythrocytes by exogenously added amphiphiles. These results are in favor of the hypothesis that a significant pool of nanovesicles in blood isolates is created during their harvesting. The identity, shape, size and composition of NVs in isolates strongly depend on the technology of their harvesting.

  7. [해외논문]   KeepEX, a simple dilution protocol for improving extracellular vesicle yields from urine

    초록

    Urinary extracellular vesicles (EVs) are a promising source of biomarkers, which can be obtained in a non-invasive manner. However, the yield of EVs from urine samples may be insufficient for various analyses due to the entrapment of EVs by the Tamm-Horsfall protein (THP) meshwork. Here, we developed a simple dilution protocol to increase the urinary EV yield by disrupting the interaction between THP filaments and EVs with the help of alkaline pH and lowered ionic concentration. The integrity of the EVs and THP was assessed by electron microscopy. The effect of the protocol on the EV yield was quantified against an undiluted control by western blotting of four EV markers, nanoparticle tracking analysis and measuring of the RNA/miRNA concentration of the EV samples. The average EV yield from the dilution protocol was 2-7 fold the yield from the undiluted control i.e. increased by 130-624% as measured by western blotting and NTA. The yield increased most from samples with a high THP to EV ratio. The morphology and size range of the EVs were unaltered by the protocol. However, RNA/miRNA yields were the same as from the undiluted control and THP filaments could still be detected in EV samples. The dilution protocol, that we named KeepEX, provides a simple and efficient way to prevent loss of EVs thus increasing their yield from urine. Since KeepEX does not require individual adjustment of sample pH nor extra centrifugation steps, it could be used on its own or in combination with other EV purification protocols to improve EV isolation particularly from small urine volumes.

  8. [해외논문]   Extracellular vesicles in food: Experimental evidence of their secretion in grape fruits  

    Perez-Bermudez, P. ; Blesa, J. ; Soriano, J.M. ; Marcilla, A.

    초록

    In the last decade, the number of studies related with extracellular vesicles (EVs) has dramatically grown since their role as key part of intercellular communication has been confirmed. EVs, as transporter of distinct bioactive molecules, can take part in different physiological mechanisms and have been gaining attention as potential tools with a wide range of therapeutic effects. Whereas a high number of studies have been published related to mammalian derived EVs, including products as food source, the existence of EVs in plants still is controversial. Recent descriptions of vesicles derived from edible plants show that they might contain pharmacological active molecules. In this context, EVs from food are attracting increasing interest due to their relevance in modulating cellular processes (involved in health and disease), as well as therapeutic vehicles. The present work aims to summarize the current knowledge on exosomes in foods, actually limited to only four FAO groups (Milk, Starchy roots and tubers, Nuts and seeds, and Fruits). In addition, we have further characterized EVs isolated from grape berry juice by classical differential centrifugation, and described a preliminary dissection of their secretion in vivo.

  9. [해외논문]   Metabolically active extracellular vesicles released from hepatocytes under drug-induced liver-damaging conditions modify serum metabolome and might affect different pathophysiological processes

    초록

    Hepatocytes are involved in the endogenous and drug metabolism; many of the enzymes involved in those processes are incorporated into extracellular vesicles and secreted into the bloodstream. Liver-damaging conditions modify the molecular cargo of those vesicles significantly. However, no information about the effect of these hepatic vesicles on the extracellular environment is available. Drug-induced liver damage increases the number of circulating extracellular vesicles and affects the release and content of hepatocyte-derived vesicles. In this work, we evaluated the metabolic effect of these vesicles on the composition of the serum. We performed a targeted ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS) metabolomics analysis of serum samples. The samples had been first incubated with hepatic extracellular vesicles from hepatocytes challenged with acetaminophen or diclofenac. The incubation affected the serum levels of 67 metabolites, such as amino acids and different species of lipids. The metabolites included various species of phosphatidylcholines and phosphatidylethanolamines. These compounds are the components of biological membranes; our observations suggest that the vesicles might take part in remodelling and maintenance of the membranes. Alterations in the levels of some other serum metabolites might have deleterious consequences, for example, the tetracosanoic acid with its cardiovascular effects. However, some of the metabolites whose levels were increased, including alpha-linoleic and tauroursodeoxycholic acids, have been reported to have a protective effect. Our targeted metabolomics analysis indicated that the hepatic extracellular vesicles act as nano-metabolic machines supplying the extracellular environment with the means to integrate diverse tissue responses. In conclusion, we show that the hepatic extracellular vesicles are metabolically active and might play a role in the physiopathological response to hepatic insults, including drug-induced liver injury.

    초록

    It was the aim of this work to determine whether the plasma concentration of extracellular vesicles (EVs) in active diabetic Charcot neuroarthropathy (CN) is connected to the inflammatory markers, temperature elevation in the affected foot and concentration of soluble receptor for advanced glycation end products (RAGE). EVs were isolated from peripheral blood of 35 patients with active CN. EVs were counted after repetitive centrifugation and washing of samples, by flow cytometry. Foot temperature was measured by infrared thermometer. Concentration of soluble receptor for advanced glycation end products (RAGE) was determined by enzyme-linked immunosorbent assay (ELISA). We found statistically significant correlations of EV concentration (but not soluble RAGE concentration) with C-Reactive Protein (CRP) and with temperature difference between the affected and the contralateral foot (r=0.40, p=0.032; r=0.89, p -8 , respectively). We provide evidence that the concentration of EVs is related to elevation of markers of inflammation (CRP and foot temperature difference) in acute Diabetic CN. EV-based markers could be considered as a potential aid in early diagnosis of CN.
