PMID	Title	Abstract
34562426	Mast cells-derived exosomes worsen the development of experimental cerebral malaria.	Exosomes were successfully isolated from culture supernatants of mouse MCs line (P815 cells) and characterized by spherical vesicles with the diameter of 30-150 nm, and expression of typical exosomal markers (e.g., CD9, CD63, and CD81).
34567283	Cancer-Derived Exosomal miR-651 as a Diagnostic Marker Restrains Cisplatin Resistance and Directly Targets ATG3 for Cervical Cancer.	The exosomes isolated from HeLa cells were rich in CD63, CD9, and CD81 proteins, thereby identifying the isolated exosomes.
34567775	Electrochemical micro-aptasensors for exosome detection based on hybridization chain reaction amplification.	Specifically, exosomes are enriched on CD63 aptamer-functionalized electrodes and then recognized by HCR products with avidin-horseradish peroxidase (HRP) attached using EpCAM aptamers as bridges.
34616478	Paeoniflorin Effect of Schwann Cell-Derived Exosomes Ameliorates Dorsal Root Ganglion Neurons Apoptosis through IRE1α Pathway.	ER stress initiating factor GRP78, the IRE1 Compared with the exosomes in the HG group, the exosomes after the intervention of PF can significantly reduce the expression of GRP78, IRE1 PF regulates the information of ER stress carried by SC-EXOs and further affects downstream of IRE1 Copyright © 2021 Yanbo Zhu et al. Exosomes were obtained from SCs by ultracentrifugation and identified according to marker proteins, including CD63, Alix, Hsp70, and TSG101.
34632781	Rolling Circle Amplification-Assisted Flow Cytometry Approach for Simultaneous Profiling of Exosomal Surface Proteins.	In this work, specific anti-CD63 antibody-conjugated magnetic beads were first utilized to capture exosomes.
34635251	ExoPRIME: Solid-phase immunoisolation and OMICS analysis of surface-marker-specific exosomal subpopulations.	Here, we report a direct, one-step exosome sampling technology, ExoPRIME, for selective capture of CD63 Copyright © 2021 Elsevier B.V. All rights reserved.
34645935	Exosomal CD63 in critically ill patients with sepsis.	CD63 is one of the tetraspanin protein family members that is ubiquitously expressed on exosomes and is involved in the signal transduction of various types of immune cells.
34656547	Plasma exosomal proteomic studies of corneal epithelial injury in diabetic and non-diabetic group.	TEM indicated that the exosomes had a double-concave disc-like appearance, with a size of about 100 nm, and Western blot expressed as CD63 and TSG101.
34684727	Proteomic Signature of Extracellular Vesicles for Lung Cancer Recognition.	By applying targeted mass spectrometry with stable isotope-labeled peptide standards, we assessed the levels of 28 EV-associated proteins, including the conventional exosome markers CD9, CD63, CD81, CD82, and HSPA8, in vesicles derived from the lung cancer cell lines NCI-H23 and A549.
34686196	Decreased exosome-delivered miR-486-5p is responsible for the peritoneal metastasis of gastric cancer cells by promoting EMT progress.	Exosomes from GC9811 cells (Con-Exo) and from GC9811-P cells (PM-Exo) were extracted by ultracentrifugation, which were identified with transmission electron microscopy (TEM) and nanoparticle trafficking analysis, as well as the expression of CD9, CD63, and CD81 detected by Western blot assay.
