PMID	Title	Abstract
28114422	A Comparative Study of Serum Exosome Isolation Using Differential Ultracentrifugation and Three Commercial Reagents.	The isolated exosomes were characterized based upon size, quantity, zeta potential, CD63 and CD9 protein expression, and exosomal RNA (exRNA) quality and quantity using several complementary methods: nanoparticle tracking analysis (NTA) with ZetaView, western blot, transmission electron microscopy (TEM), the Agilent Bioanalyzer system, and droplet digital PCR (ddPCR).
28116765	Urinary exosomes as a novel biomarker for evaluation of α-lipoic acid's protective effect in early diabetic nephropathy.	In summary, we emphasize short-term α-LA could protect the kidney in the early DN against general oxidative stress, particularly the urinary CD63-positive exosome could be a potential sensitive and therapeutic indicator. Notably, the CD63 expressing of exosomes in urine was found higher in the normoalbuminuria patients compared with those in microalbuminuria, parallelly only declined markedly after α-LA administration in normoalbuminuria patients.
28129550	ATP binding cassette A1 (ABCA1) mediates microparticle formation during high-density lipoprotein (HDL) biogenesis.	MPs do not contain apoA-I, but contain flotilin-2, a marker of plasma membrane, and CD63, an exosome marker.
28161063	Influence of maternal BMI on the exosomal profile during gestation and their role on maternal systemic inflammation.	Total exosomes and specific placenta-derived exosomes were determined by Nanoparticle Tracking Analysis (NanoSight™) using quantum dots coupled with CD63 or PLAP antibodies.
28167415	A visible and colorimetric aptasensor based on DNA-capped single-walled carbon nanotubes for detection of exosomes.	Aptamers, specific to exosomes transmembrane protein CD63, are absorbed onto the surface of s-SWCNTs and improve the minic peroxidase activity of s-SWCNTs, which can efficiently catalyze H Copyright © 2017 Elsevier B.V.

28251957	[Contamination of exosome preparations, isolated from biological fluids].	All exosome preparations (over 200) contained exosomes, which were identified by immuno-electron microscopy using antibodies to tetraspanins CD63 or CD9.
28346015	The role of exosomes derived from cerebrospinal fluid of spinal cord injury in neuron proliferation in vitro.	The results demonstrated these exosomes all expressed CD9, CD63, CD81, Alix and Tsg101; however, only exosomes derived from cerebrospinal fluid of SCI could promote proliferation of neuron via ERK signaling pathway, and decrease cell apoptosis.

28360912	Exosomes Isolated from Ascites of T-Cell Lymphoma-Bearing Mice Expressing Surface CD24 and HSP-90 Induce a Tumor-Specific Immune Response.	No abstract available
28485529	Exosomes mediate interepithelial transfer of functional P-glycoprotein in chronic rhinosinusitis with nasal polyps.	P-gp content of purified mucus exosomes was characterized by transmission electron microscopy and enzyme-linked immunosorbent assay. P-gp was significantly enriched in CRSwNP exosomes relative to control (median 198.5; interquartile range 123.6-270.5 vs. 74.4; 41.3-95.0 pcg P-gp/10 Here we demonstrate the presence and P-gp enrichment of mucus-derived exosomes, or rhinosomes, in CRSwNP. The aims of this study were 1) to determine whether CRSwNP mucus exosomes are enriched with P-gp, and 2) whether exosomal P-gp can be functionally transferred to autologous epithelial cells as a putative mechanism for the proinflammatory overexpression of P-gp in CRSwNP.
