Micro-RNAs (miRNAs) derived from small extracellular vesicles (sEVs) have been recognized as novel circulating biomarkers of disease. To identify specific miRNAs derived from plasma sEVs for TDs\u2019 diagnosis and prognosis, we used official EV isolation and purification methods to characterize the plasma-derived EV miRNAs from children with different types of TDs. Nanoparticle tracking analysis, transmission electron microscopy, and immunoblot analysis of EV surface markers were applied to confirm the features and quality of sEVs. The RNA sequencing (RNA-seq) approach was adapted to identify novel circulating sEVs-derived miRNAs with altered expression levels in paired comparisons of TDs versus healthy controls (HCs), transient tic disorder (TTD) versus chronic motor or vocal tic disorder (CTD), and TTD versus Tourette Syndrome (TS). GO term and KEGG pathway were performed for functional analysis and the receiver operator curve analysis was followed to test the diagnosis efficacy of differentially expressed miRNAs (DEMs) derived from plasma sEVs among paired groups, namely, TDs versus HCs, TTD versus CTD, and TTD versus TS. As a result, 10 miRNAs (hsa-let-7a, hsa-let-7b, hsa-let-7c, hsa-let-7e, hsa-let-7f, hsa-miR-25-3p, hsa-miR-29a-3p, hsa-miR-30b-5p, hsa-miR-125b-5p, and hsa-miR-1469) have demonstrated a significantly different expression signature in the TDs group compared to HCs with excellent area under curve (AUC) values of 0.99, 0.973, 0.997, 1, 0.99, 0.997, 0.987, 0.993, 0.977, and 0.997, respectively, and the diagnostic efficacy of miRNAs was also estimated for discriminating TTD from CTD or TS. In our research, we finally obtained several potential sEVs-derived miRNA biomarkers to assess the diagnosis and prognosis of TDs.<\/jats:p>","DOI":"10.3390\/brainsci12070829","type":"journal-article","created":{"date-parts":[[2022,6,26]],"date-time":"2022-06-26T09:00:13Z","timestamp":1656234013000},"page":"829","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Micro-RNAs from Plasma-Derived Small Extracellular Vesicles as Potential Biomarkers for Tic Disorders Diagnosis"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7833-9990","authenticated-orcid":false,"given":"Yilong","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Neurology, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"},{"name":"National Clinical Research Center for Child Health, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuebin","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Neurology, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"},{"name":"National Clinical Research Center for Child Health, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haihua","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Neurology, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"},{"name":"National Clinical Research Center for Child Health, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengying","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Neurology, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"},{"name":"National Clinical Research Center for Child Health, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaotong","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Neurology, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"},{"name":"National Clinical Research Center for Child Health, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Neurology, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"},{"name":"National Clinical Research Center for Child Health, Children\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"513","DOI":"10.1097\/WCO.0000000000000356","article-title":"Tics and Tourette\u2019s: Update on pathophysiology and tic control","volume":"29","author":"Ganos","year":"2016","journal-title":"Curr.
