PMID	Title	Abstract
34321877	Antibacterial Effect of Honey-Derived Exosomes Containing Antimicrobial Peptides Against Oral Streptococci.	Recently, our group found exosome-like extracellular vesicles (EVs) in Molecular characterization of HEc-EVs identified for the first time important conserved exosome markers such as CD63 and syntenin, and the antibacterial molecules MRJP1, defensin-1 and jellein-3 were found as intravesicular cargo.
34335040	Release and Actions of Inflammatory Exosomes in Pulmonary Emphysema: Potential Therapeutic Target of Acupuncture.	However, EA of non-specific BL23 together with ST36 acupoint had no effects on NLRP3 inflammasome activation, exosome release and associated lung pathology during emphysema. IL-1β, a prototype NLRP3 inflammasome activating product, was also found to have increased in the lung during emphysema, which was colocalized with CD63 (an exosome marker), an indicative of inflammatory exosome formation. NLRP3 inflammasome activation in concert with increased release of exosomes containing IL-1β or other inflammasome products contributes to the development of lung inflammation and injury during PPE-induced emphysema and that EA of lung-specific acupoints attenuates inflammasome activation and exosome release, thereby reducing inflammatory response in the lung of mice with emphysema. The present study tested the hypothesis that exosome-mediated release of NLRP3 inflammasome products instigates the inflammatory response in the lung during emphysema, a type of chronic obstructive pulmonary disease (COPD) and that electroacupuncture (EA) may attenuate emphysema by inhibition of NLRP3 inflammasome activation and consequent inflammation.
34366842	The Depolarization-Evoked, Ca2+-Dependent Release of Exosomes From Mouse Cortical Nerve Endings: New Insights Into Synaptic Transmission.	The structural and biochemical analysis unveiled that supernatants contain vesicles that have the size and the shape of exosomes, which were immunopositive for the exosomal markers TSG101, flotillin-1, CD63, and CD9.
34383347	Exosomal tumor necrosis factor-α from hepatocellular cancer cells (Huh-7) promote osteoclast differentiation.	Huh-7 exosomes were characterized for size and exosome marker expressions (CD63, Alix).
34384449	Isolation and identification of exosomes from feline plasma, urine and adipose-derived mesenchymal stem cells.	Detected particles showed the normal size (30-100 nm) and morphology described for exosomes, as well as presence of the transmembrane protein (TSG101, CD9, CD63, and CD81) known as exosomal marker.
34407412	CD63-mediated cloaking of VEGF in small extracellular vesicles contributes to anti-VEGF therapy resistance.	As described here, we demonstrate that cancer-derived small extracellular vesicles package increasing quantities of VEGF and other factors in response to anti-VEGF therapy. The packaging process of VEGF into small extracellular vesicles (EVs) is mediated by the tetraspanin CD63.
34423573	Primary breast cancer biomarkers based on glycosylation and extracellular vesicles detected from human serum.	Our aim was to develop an approach to detect the aberrant glycosylation of mucins and extracellular vesicle-associated glycoproteins from human sera using fluorescent nanoparticles, and preliminarily evaluate this approach for the differential diagnosis of breast cancer. The glycosylation of circulating extracellular vesicle-associated glycoproteins, and mucins may offer targets for detection methods and have been only explored in a limited capacity.
34434533	Androgens alter the heterogeneity of small extracellular vesicles and the small RNA cargo in prostate cancer.	In this study, we report that plasma-derived circulating vesicles consisting of CD9 and double-positive for CD9 and Prostate Specific Membrane Antigen (PSMA) are increased in patients with advanced metastatic prostate cancer, whereas double positives for CD9 and CD63 small extracellular vesicles (S-EVs) are significantly higher in patients with localised prostate cancer.
34440851	Ewing Sarcoma-Derived Extracellular Vesicles Impair Dendritic Cell Maturation and Function.	Here, EVs were purified from EwS and fibroblast cell lines and exhibited characteristics of small EVs, including size (100-170 nm) and exosome markers CD63, CD81, and TSG101.
34442609	The Specific Gravity-Free Method for the Isolation of Circulating Tumor KRAS Mutant DNA and Exosome in Colorectal Cancer.	We present a dual isolation system including a polydopamine (PDA)-silica-coated alginate bead for circulating tumor DNA (ctDNA) capture and an anti-CD63 immobilized bead for exosome capture.
