PMID	Title	Abstract
31647995	Endothelial acid ceramidase in exosome-mediated release of NLRP3 inflammasome products during hyperglycemia: Evidence from endothelium-specific deletion of Asah1 gene.	However, it remains unknown whether and how exosomes mediate the release of NOD-like receptor pyrin domain 3 (NLRP3) inflammasome products such as interleukin-1 beta (IL-1β) from endothelial cells.
31660712	Ultrasensitive Detection of Exosomes by Target-Triggered Three-Dimensional DNA Walking Machine and Exonuclease III-Assisted Electrochemical Ratiometric Biosensing.	CD63 aptamer and EpCAM aptamer were used for the detection of MCF-7 cell-secreted exosome.
31665020	Clinical significance of PD-L1 expression in serum-derived exosomes in NSCLC patients.	Exosomes were next solubilized for Exo-PD-L1 detection by enzyme-linked immuno-sorbent assay (ELISA).
31666406	[Exosomes secretion and autophagy in long-term protection of neurons from excitotoxic damage].	Exosomes are secreted at the development of resistance during deprivation and at the first 24 h after preconditioning, as was shown by dot blot of extracellular fluid using anti-CD63 antibody.
31675489	Environmental pollutant induced cellular injury is reflected in exosomes from placental explants.	Regardless of treatment, placental expressed exosomes markers (PLAP, CD9, CD63, 81 and ALIX), had a size distribution between 50 and 175 nm and were present in the conditioned medium at 5-8 x 10 Environmental exposure of placental explants did not change the quantity of exosomes or their characteristics.
31676071	Disruption of Core 1-mediated O-glycosylation oppositely regulates CD44 expression in human colon cancer cells and tumor-derived exosomes.	CD44 in exosomes might be a potential biomarker of aberrant O-glycosylation. CD63 immunoaffinity-purified exosomes are examined for CD44 expression by flow cytometric analyses. Exosomes derived from LS174T and LSC human colon cancer cell lines were isolated from cell culture supernatant and pulled down using tetraspanin-specific antibody CD63 immunoaffinity magnetic beads. In this research, we aimed to investigate whether CD44 expression in cells and exosomes can be influenced by disruption of Core 1-mediated O-glycosylation. The percentages of CD44 in exosomes derived from abnormally O-glycosylated cells are significantly higher compared with those derived from normal ones, however, which is surprisingly contrary to the cellular expression levels of CD44.
31712601	Extracellular Vesicle-derived circular RNAs confers chemoresistance in Colorectal cancer.	Our exosomes were translucent cup-shaped structures under TEM with differential expression of TSG101, CD9, and CD63.
31713717	Human breast milk exosomes attenuate intestinal damage.	HBM exosomes were isolated and characterized by positive CD63 and negative calnexin markers from western blot, nanoparticle tracking analysis and transmission electron microscopy.
31736169	Exosomes derived from adipose tissue, bone marrow, and umbilical cord blood for cardioprotection after myocardial infarction.	Exosomes were derived from BMMSCs, ADMSCs, and UCBMSCs, and identified by morphological observation and CD63 expression detection. NRCMs treated with exosomes derived from BMMSCs, ADMSCs, and UCMSCs reduced the NRCM apoptosis and promoted angiogenesis by increasing levels of VEGF, bFGF, and HGF.
31743567	Medial calcification in the arterial wall of smooth muscle cell-specific Smpd1 transgenic mice: A ceramide-mediated vasculopathy.	The study was performed to test whether lysosomal acid sphingomyelinase (murine gene code: Smpd1)-derived ceramide contributes to the small extracellular vesicle (sEV) secretion from SMCs and consequently leads to AMC.
