PMID	Title	Abstract
29416092	CD63, MHC class 1, and CD47 identify subsets of extracellular vesicles containing distinct populations of noncoding RNAs.	No abstract available
29430178	Engineered exosome-mediated delivery of functionally active miR-26a and its enhanced suppression effect in HepG2 cells.	The engineered exosomes were shown to bind selectively to HepG2 cells via the scavenger receptor class B type 1-Apo-A1 complex and then internalized by receptor-mediated endocytosis. The tumor cell-targeting function of these engineered exosomes was introduced by expressing in 293T cell hosts, the gene fusion between the transmembrane protein of CD63 and a sequence from Apo-A1.
29450143	Purified horse milk exosomes contain an unpredictable small number of major proteins.	Well-purified exosomes contained from five to eight different major proteins: CD81, CD63 receptors, beta-lactoglobulin and lactadherin were common to all preparations, while actin, butyrophilin, lactoferrin, and xanthine dehydrogenase were found only in some of them.
29452091	Expression profiles and clinical value of plasma exosomal Tim-3 and Galectin-9 in non-small cell lung cancer.	Exosomes were isolated from plasma by commercial exosome precipitation solution and identified by western blotting of CD63 and transmission electron microscopy.
29468680	Proinflammatory role of blister fluid-derived exosomes in bullous pemphigoid.	Furthermore, CD63 was localized mostly to keratinocytes and infiltrative granulocytes in skin lesions, suggesting that these cells were the possible sources of exosomes in blister fluid. We found that exosomes isolated from blister fluids of patients with bullous pemphigoid showed the expected size and expressed the marker proteins CD63, CD81, and CD9.
29484119	Breast cancer cell-derived exosomes and macrophage polarization are associated with lymph node metastasis.	The MDA-MB-231 cancer cell line expressing the exosomal CD63-red fluorescence (RFP) fusion protein was generated to noninvasively visualize exosome transfer into cancer cells and macrophages.
29518183	Cardioprotection by cardiac progenitor cell-secreted exosomes: role of pregnancy-associated plasma protein-A.	PAPP-A knockdown prevented CPC exosome-mediated cardioprotection both in vitro and in vivo. Proteomics profiling identified pregnancy-associated plasma protein-A (PAPP-A) as one of the most highly enriched proteins in CPC vs. BMC exosomes. The active form of PAPP-A was detected on CPC exosome surfaces. These results suggest that CPC-secreted exosomes may be more cardioprotective than BMC-secreted exosomes, and that PAPP-A-mediated IGF-1 release may explain the benefit. Vesicle preparations were predominantly composed of exosomes based on particle size and marker expression (CD9, CD63, CD81, Alix, and TSG-101).
29539618	Non-Proximal Renal Tubule-Derived Urinary Exosomal miR-200b as a Biomarker of Renal Fibrosis.	Sorting the proximal tubular exosomes with the CD13 protein marker revealed that miR-200b in the CD13+ group was extremely low; however, the result was significantly different in the CD13- group but not in the CD13+ group.
29575602	Exosomal tetraspanins as regulators of cancer progression and metastasis and novel diagnostic markers.	CD151 preferentially targets exosomes to lung, lymph node and stroma cells. EXO CARTA database shows the presence of CD151 in exosomes of colorectal, melanoma, ovarian and prostate cancers.
29626979	Placental exosomes profile in maternal and fetal circulation in intrauterine growth restriction - Liquid biopsies to monitoring fetal growth.	Total and specific placenta-derived exosomes were determined using quantum dots coupled with CD63 Maternal concentrations of CD63 Quantification of placental exosomes in maternal plasma reflects fetal growth and it may be a useful indicator of placental function.
