     <dcterms:abstract xml:lang="fr">Le syndrome de Sjögren (SGS) est une maladie auto-immune caractérisée par la destruction de l’épithélium des glandes exocrines causant un syndrome sec, et dont la principale complication est le lymphome. De nouveaux biomarqueurs diagnostiques et pronostiques sont nécessaires dans le SGS. Les vésicules extracellulaires (EVs) plasmatiques sont des candidates prometteuses, dont le potentiel n’a pas été exploré. Nous caractérisons ici sur le plan phénotypique et protéomique les EVs de patients atteints de SGS primaire (pSS, n=12), en comparaison à des donneurs sains (n=10) et à des patients atteints de lupus érythémateux systémique (n=12). Nous montrons que des populations spécifiques d’EVs plasmatiques sont augmentées dans le pSS et identifions une signature protéomique spécifique dans les EVs plasmatiques de patients atteints de pSS. Globalement, nos résultats valident la pertinence des EVs plasmatiques comme biomarqueurs dans le SGS.</dcterms:abstract>
     <dcterms:abstract xml:lang="en">Sjögren syndrome (SjS) is an autoimmune disease characterized by the destruction of the exocrine glands epithelia, causing sicca symptoms, and whose main complication is lymphoma. There is a need for new diagnostic and prognostic biomarkers in SjS. Plasmatic extracellular vesicles (EVs) are promising biomarker candidates, but their potential has not yet been explored in SjS. Herein, we characterize EVs from primary SjS patients (pSS, n=12) at the phenotypic and proteomic levels, compared to healthy donors (HD, n=10) and systemic lupus erythematosus patients (SLE, n=12). We show that specific plasmatic EVs subpopulations are increased in pSS. We also identify a specific pSS proteomic signature in plasmatic EVs. Overall, our results support the relevance of plasmatic EVs as biomarkers in SjS.</dcterms:abstract>
