PMID	Title	Abstract
24288129	Curcumin promotes exosomes/microvesicles secretion that attenuates lysosomal cholesterol traffic impairment.	Curcumin stimulated the release of cholesterol and the lysosomal β-hexosaminidase enzyme, as well as the exosome markers, flotillin-2 and CD63.
24335901	Reduced MiR-675 in exosome in H19 RNA-related melanogenesis via MITF as a direct target.	In addition to RNase resistance, FACS analysis showed anti-CD63-positive exosomes in culture supernatants, suggesting miR-675 could be released extracellularly and delivered to neighboring cells without degradation.
24393345	Ovarian cancer cell invasiveness is associated with discordant exosomal sequestration of Let-7 miRNA and miR-200.	Cell-conditioned media were collected and exosomes were isolated by differential and buoyant density centrifugation and characterised by Western blot (CD63 and CD9). RESULTS: Exosomes were identified with by the presence of typical cup-shaped spherical vesicle and the expression of exosome markers: CD63, CD9.
24428462	Differences in exosome populations in human breast milk in relation to allergic sensitization and lifestyle.	Furthermore, women with an anthroposophic lifestyle had significantly lower MUC1 expression on their HLA-DR-enriched milk exosomes and up-regulated levels of CD63 on CD63-enriched exosomes compared with nonanthroposophic mothers. Isolated exosomes were captured on anti-MHC-class II- or anti-CD63 beads and analyzed by flow cytometry. Notably, mothers whose children developed sensitization had an increased amount of HLA-ABC on their milk exosomes enriched for CD63. Significantly lower levels of MUC1 were detected on CD63-enriched exosomes from sensitized mothers compared with nonsensitized.
24450402	Platelets store laminins 411/421 and 511/521 in compartments distinct from α- or dense granules and secrete these proteins via microvesicles.	The exosomes were immunoprecipitated with magnetic microbeads coated with anti-CD63 antibodies.
24569882	The p75 neurotrophin receptor evades the endolysosomal route in neuronal cells, favouring multivesicular bodies specialised for exosomal release.	Consistently, depolarisation by KCl induced the liberation of previously endocytosed full-length p75 into the extracellular medium in exosomes.
24614226	Extracellular vesicles in luminal fluid of the ovine uterus.	The isolated extracellular vesicles were positive for two common markers of exosomes (CD63 and HSP70) by Western blot analysis.
24662828	Exosomal HIF1α supports invasive potential of nasopharyngeal carcinoma-associated LMP1-positive exosomes.	Further, immunohistochemical analysis of NPC tumor tissues revealed direct correlation between protein levels of LMP1 and of the endosome/exosome marker tetraspanin, CD63, which suggests an increase in exosome formation in this EBV-positive malignancy. In addition, we provide evidence that HIF1α itself participates in exosome-mediated pro-metastatic effects in recipient cells, as exosome-mediated delivery of active and inactive forms of HIF1α results in reciprocal changes in the expression of E- and N-cadherins associated with EMT. We now demonstrate that endogenous HIF1α is detectable in exosomes and that LMP1 significantly increases levels of HIF1α in exosomes.
24722878	Microfluidic device (ExoChip) for on-chip isolation, quantification and characterization of circulating exosomes.	To capture specific exosomes, we employed "ExoChip", a microfluidic device fabricated in polydimethylsiloxane (PDMS) and functionalized with antibodies against CD63, an antigen commonly overexpressed in exosomes.
24825548	Cardiomyocytes mediate anti-angiogenesis in type 2 diabetic rats through the exosomal transfer of miR-320 into endothelial cells.	While exosomes derived from GK myocytes (GK-exosomes) displayed similar size and molecular markers (CD63 and CD81) to those originated from the control Wistar rat myocytes (WT-exosomes), their regulatory role in angiogenesis is opposite.
