32290097	Alphaherpesvirus gB Homologs Are Targeted to Extracellular Vesicles, but They Differentially Affect MHC Class II Molecules.	No abstract available
32318822	Immunoassay-type biosensor based on magnetic nanoparticle capture and the fluorescence signal formed by horseradish peroxidase catalysis for tumor-related exosome determination.	MNPs were used as the substrate to capture exosomes by modifying the CD63 antibody on MNPs surface.
32322309	Effect of circulating exosomes derived from normal-weight and obese women on gluconeogenesis, glycogenesis, lipogenesis and secretion of FGF21 and fetuin A in HepG2 cells.	Plasma exosomes isolated from four obese (O-Exo) women and four normal-weight (N-Exo) female candidates were characterized for size, zeta potential, and CD63 protein expression and were used for stimulation of HepG2 cells.
32328746	Protective effects of bovine milk exosomes against oxidative stress in IEC-6 cells.	To assess the protective effects of exosomes, IEC-6 cells were pretreated with exosomes, followed by H The isolated bovine milk exosome were positive for CD63 and CD9 expression.
32338917	Comparative Glycomic Analysis of Exosome Subpopulations Derived from Pancreatic Cancer Cell Lines.	A hierarchical clustering analysis using 19 glycomic profiles confirmed that most subpopulations, except CD81-positive exosomes, could be distinguished according to the host-cell species. Principal component analysis and subsequent lectin-affinity capturing of intact exosomes highlighted that CD81-positive exosomes preferentially expressed not PHA-L- but LEL-binding proteins on their surfaces. The surfaces of extracellular vesicles were labeled with Cy3 and captured by magnetic beads with antibodies against tetraspanins (CD9, CD63, and CD81).
32342086	An engineered exosome for delivering sgRNA:Cas9 ribonucleoprotein complex and genome editing in recipient cells.	To improve the loading efficiency of Cas9 proteins into exosomes, we artificially engineered exosomes by fusing GFP and GFP nanobody with exosomal membrane protein CD63 and Cas9 protein, respectively.
32350252	A live cell reporter of exosome secretion and uptake reveals pathfinding behavior of migrating cells.	Our previous live-cell reporter, pHluorin-CD63, allows dynamic subcellular monitoring of exosome secretion in migrating and spreading cells.
32350913	Pancreatic cancer-derived exosomes induce apoptosis of T lymphocytes through the p38 MAPK-mediated endoplasmic reticulum stress.	We (1) treated peripheral T lymphocytes with pancreatic cancer-derived exosomes, tagged CD63 with tdTomato, to trace exosome transfer from pancreatic cancer cells to T lymphocytes; (2) carried out a cytotoxicity assay of exosome-treated T lymphocytes using the Real Time Cellular Analysis system; (3) performed RNA sequencing and gene set enrichment analysis to explore the pivotal signaling pathway that mediates apoptosis in exosome-treated T lymphocytes; and (4) demonstrated the role of p38 mitogen-activated protein kinase (MAPK) and endoplasmic reticulum (ER) stress in exosome-induced T-lymphocyte apoptosis.
32368986	Anti-Inflammatory Effects of Plasma Circulating Exosomes Obtained from Normal-Weight and Obese Subjects on Hepatocytes.	The exosomes were characterized and approved for CD63 expression (common exosomal protein marker) and morphology/size using the western blot and TEM methods, respectively.
32375155	A Pilot Study of Urinary Exosomes in Alzheimer's Disease.	Exosomes can spread toxic amyloid-beta (Aβ) and hyperphosphorylated tau between cells, contributing to neuronal loss in Alzheimer's disease (AD). In this study, enzyme-linked immunosorbent assay was used to detect the levels of Aβ1-42 and P-S396-tau (normalized by CD63) in urinary exosomes of AD patients and matched healthy subjects. The differences in levels of Aβ1-42 and P-S396-tau and the quantity of urinary exosomes between AD patients and healthy controls may provide a basis for early diagnosis of AD. We found that the levels of Aβ1-42 and P-S396-tau in the urinary exosomes of AD patients were higher than those of matched healthy controls.
