... In the emerging field of phyto-nanotechnology, 30–200 nm plant-derived extracellular vesicles (PDEVs) are now known to contain active biomolecules that mediate cell-to-cell communication processes in a manner very similar to exosomes in mammalian cells. The ability to deliver cargo across cellular membranes suggests that botanical systems could be used in the mass production of therapeutic vectors ...

Abstract:
... Activation of hepatic stellate cells (HSCs) is a key cause of liver fibrosis. However, the mechanisms leading to the activation of HSCs are not fully understood. In the pathological process, acid-sensing ion channel 1a (ASIC1a) is widely involved in the development of inflammatory diseases, suggesting that ASIC1a may play an important role in liver fibrosis. We found that in an acidic environment, ...
... Sesquiterpenyl epoxy-cyclohexenoids (SECs) that depend on a polyketide synthase–terpenoid synthase (PKS–TPS) pathway are widely distributed in plant pathogenic fungi. However, the biosynthesis and function of the acetylated SECs still remained cryptic. Here, we identified that AOL_s00215g 273 (273) was responsible for the acetylation of SECs in Arthrobotrys oligospora via the construction of Δ273, ...

Abstract:
... SCOPE: Phenotypic switch of macrophage polarization in adipose tissue has been associated with obesity‐induced adipose tissue inflammation (OATI). Therefore, this study aims to explore the possible mechanism of adipocytes‐derived exosomes (ADEs) carrying microRNA‐1224 (miR‐1224) in M2 macrophage polarization of OATI. METHODS AND RESULTS: miR‐1224‐knockout (miR‐1224‐KO) mice for this study, and iso ...
... Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder in women of childbearing age. Adipose mesenchymal stem cells (AMSCs) secrete cytokines involved in the regulation of metabolism and immunity. However, it remains unclear whether exosomes secreted by AMSCs (AMSC-EXOs) can rescue the polycystic phenotype and metabolic dysfunction in PCOS ovaries. Here, we show that ...
... miR-495 and miR-142–3p suppress inflammatory response. Circ_0075932 is overexpressed in the burned skin of obese individuals and is involved in the regulation of PUM2 and AuroraA kinase, thus activating the NF-kB pathway. Obesity significantly influences the length of hospital stay for paediatric burn patients, who present symptoms of slower healing or greater functional impairment. In this study, ...
... Anthocyanins are a group of phytochemicals responsible for the purple or red color of plants. Additionally, they are recognized to have health promoting functions including anti-cardiovascular, anti-thrombotic, anti-diabetic, antimicrobial, neuroprotective, and visual protective effect as well as anti-cancer activities. Thus, consumption of anthocyanin supplement or anthocyanin-rich foods has been ...

Abstract:
... Point-of-care testing (POCT), as one part of in vitro diagnostic (IVD), has been gradually used in early diagnosis and personalized treatment in the clinics. Accurate and sensitive detection of clinically related biomarkers is valuable, especially using the methods with simple, rapid, high throughput, miniaturization, and low cost. Nowadays, various biomolecules have been regarded as biomarkers fo ...
... Correct elucidation of physiological and pathological processes mediated by extracellular vesicles (EV) is highly dependent on the reliability of the method used for their purification. Currently available chemical/physical protocols for sample fractionation are time-consuming, often scarcely reproducible and their yields are low. Immuno-capture based approaches could represent an effective purifi ...
... In light of the significance of exosomes in cancer diagnosis and treatment, it is important to understand the components and functions of exosomes. Herein, an all-in-one strategy has been proposed for comprehensive characterization of exosomal proteins based on nanoporous TiO₂ clusters acting as both an extractor for exosome isolation and a nanoreactor for downstream molecular profiling. With the ...

Abstract:
... Unresolved inflammation compromises diabetic wound healing. Recently, we reported that inadequate RNA packaging in murine wound-edge keratinocyte-originated exosomes (Exoκ) leads to persistent inflammation [Zhou, X.ACS Nano2020, 14(10), 12732−12748]. Herein, we use charge detection mass spectrometry (CDMS) to analyze intact Exoκ isolated from a 5 day old wound-edge tissue of diabetic mice and a he ...

Abstract:
... BACKGROUND: Toxoplasma gondii is a zoonotic intracellular protozoon that is estimated to infect about 30% of the world’s population, resulting in toxoplasmosis in immunocompromised patients and adverse outcomes in cases of primary infection during pregnancy. Exosomes are tubular vesicles secreted by cells, and function in intercellular communication. It has been reported that the exosomes secreted ...
... Despite emerging importance of tumor cells-derived exosomes in cancer metastasis, the heterogeneity of exosome populations has largely hampered systemic characterization of their molecular composition, biogenesis, and functions. This study communicates a novel method for predicting and targeting pre-metastatic sites based on an exosome model “fluorescent cancer glyconanosomes” displaying N-glycans ...
... Extracellular vesicles (EVs) have emerged as promising candidates for multiple biomedical applications. Major types of EVs include exosomes, microvesicles, and apoptotic bodies (ABs). ABs are conferred most properties from parent cells in the final stages of apoptosis. A wide variety of sources and stable morphological features are endowed to ABs by the rigorous apoptotic program. ABs accommodate ...
... Exosomes are vesicle-like bodies of that are actively secreted by cells to the extracellular surrounding with a diameter of 40–100 nm. They have several physiological functions, such as cell-cell communication, antitumor immunity, and angiogenesis promotion. Exosomes have many important roles and are extensively distributed in various fluids throughout the body, and therefore, they are of signific ...
... Cancer-cell-derived exosomes are regarded as noninvasive biomarkers for early cancer diagnosis because of their critical roles in intercellular communication and molecular exchange. A robust aptamer-initiated catalytic hairpin assembly (AICHA) fluorescence assay is proposed for universal, sensitive detection of cancer-derived exosomes. The AICHA was verified with the specific detection of MCF-7 ce ...
... The consumption of bovine colostrum by newborn calves during the first days of life is essential to ensure the transfer of passive immunity. In addition to critical IgG, colostrum also contains non-IgG biomolecules, including microRNA (miRNA). The present study investigated the profiles of miRNA in small extracellular vesicles (sEV) isolated from bovine colostrum with high (256.5 ± 5.7 mg/mL, mean ...

Abstract:
... BACKGROUND: Oligodendrocyte precursor cells (OPCs) can proliferate and differentiate into oligodendrocytes, the only myelin-forming cells in the central nervous system. Proliferating OPCs promotes remyelination in neurodegenerative diseases. Astrocytes (ASTs) are the most widespread cells in the brain and play a beneficial role in the proliferation of OPCs. Connexin 47 (Cx47) is the main component ...
... Spinal cord injury (SCI) is catastrophic to humans and society. However, there is currently no effective treatment for SCI. Autophagy is known to serve critical roles in both the physiological and pathological processes of the body, but its facilitatory and/or deleterious effects in SCI are yet to be completely elucidated. This study aimed to use primary Schwann cell-derived exosomes (SCDEs) to tr ...
... BACKGROUND: To adapt to daily changes in the external environment, organisms have developed circadian rhythm systems with a period of approximately 24 h. Many studies have reported that both circadian rhythms and exosomes play important roles in the development and metastasis of tumors. However, whether circadian clock genes can affect the progression of tumors by regulating exosomes remains uncle ...
