Then mouse brain vascular endothelial cell (EC), human umbilical vein EC, neuroblastoma cell, and human hepatocyte cell were treated with exosomes, and changes of the protein expression in mouse brain vascular EC cells were identified.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>Proteomics analysis results showed that 859 shared proteins were detected in SDEs from ischemic and hemorrhagic MMD patients with 231 differently expressed compared with healthy controls. Bioinformatic analysis revealed dysregulated cell growth and maintenance and indicated disturbed actin dynamics in MMD, with CFL1 (Cofilin-1) and ACTR2\/3 (actin-related protein 2\/3; also known as ARP2\/3) downregulated in ischemic and hemorrhagic patients\u2019 SDEs. We also found immunity dysfunction in hemorrhagic MMD. Following treatment with MMD SDEs, mouse brain vascular EC cells showed significantly higher levels of proliferation and more ethynyl-2-deoxyuridine-positive cells compared with the healthy control group, while there were no obvious changes in the human umbilical vein EC and human hepatocyte cell. Interestingly, we also found that SDEs from ischemic MMD promoted neuroblastoma cell proliferation. Proteomic analysis of mouse brain vascular EC cells suggested that SDEs from hemorrhagic MMD patients induced dysfunction of the mitochondria in cerebrovascular ECs.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>This study highlighted potential molecular mechanisms underlying the pathogenesis of MMD patients, thereby providing new therapeutic strategies for MMD.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/strokeaha.120.032297","type":"journal-article","created":{"date-parts":[[2021,8,2]],"date-time":"2021-08-02T09:00:31Z","timestamp":1627894831000},"page":"3351-3361","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":43,"title":["Proteomic Profiling of Exosomes From Hemorrhagic Moyamoya Disease and Dysfunction of Mitochondria in Endothelial Cells"],"prefix":"10.1161","volume":"52","author":[{"given":"Xia","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Medical Molecular Biology, Department of Immunology, Institute of Basic Medical Sciences Chinese Academy of Medical Sciences, School of Basic Medicine Peking Union Medical College, Beijing, China (X.W., Y.J., J.W., W.G.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cong","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Fifth Medical Centre of PLA General Hospital, Beijing, China (C.H., L.D.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangjie","family":"Jia","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Medical Molecular Biology, Department of Immunology, Institute of Basic Medical Sciences Chinese Academy of Medical Sciences, School of Basic Medicine Peking Union Medical College, Beijing, China (X.W., Y.J., J.W., W.G.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayu","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Medical Molecular Biology, Department of Immunology, Institute of Basic Medical Sciences Chinese Academy of Medical Sciences, School of Basic Medicine Peking Union Medical College, Beijing, China (X.W., Y.J., J.W., W.G.)."},{"name":"Department of Histology and Embryology, Basic Medical University, China Medical University, Shenyang (J.W.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9907-512X","authenticated-orcid":true,"given":"Wei","family":"Ge","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Medical Molecular Biology, Department of Immunology, Institute of Basic Medical Sciences Chinese Academy of Medical Sciences, School of Basic Medicine Peking Union Medical College, Beijing, China (X.W., Y.J., J.W., W.G.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7210-056X","authenticated-orcid":true,"given":"Lian","family":"Duan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Fifth Medical Centre of PLA General Hospital, Beijing, China (C.H., L.D.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1969.00480090076012"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.114.007407"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jstrokecerebrovasdis.2017.11.026"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0036386"},{"key":"e_1_3_6_6_2","first-page":"1-8","article-title":"Trial Investigators.
