Abstract

Primary Sjögren syndrome (pSS) is a chronic autoimmune disease mainly affecting salivary and lacrimal glands. The current pSS biomarkers, serum autoantibodies, are negative in many pSS patients diagnosed with histopathology changes, indicating the need of novel biomarkers. The current therapies of pSS are merely short-term symptomatic relief and can't provide effective long-term remedy. Extracellular vehicles (EVs) are nano-sized lipid bilayer-delimited particles spontaneously released by almost all types of cells and carrying various bioactive molecules to mediate inter-cellular communications. Recent studies found that EVs from salivary gland epithelial cells and immune cells play essential roles in pSS pathogenesis. Correspondingly, EVs and their cargos in plasma and saliva are promising candidate biomarkers for pSS diagnosis. Moreover, EVs from mesenchymal stem cells have shown promises to improve pSS treatment by modulating immune responses. This review summarizes recent findings in roles of EVs in pSS pathogenesis, diagnosis, and treatment of pSS, as well as related challenges and future research directions.

Keywords: Extracellular vesicle; Immune modulation; Mesenchymal stem cells; MicroRNAs; Primary Sjögren’s syndrome; Salivary diagnostics.
