Aquaporin gene therapy corrects Sjogren's syndrome phenotype in mice

Project description:Primary Sjögren’s syndrome (pSS) is a chronic autoimmune disease that is estimated to affect 35 million people worldwide. Currently, no effective treatments exist for Sjögren’s syndrome, and there is a limited understanding of the physiological mechanisms associated with xerostomia and hyposalivation. The present work revealed that aquaporin 5 expression, a water channel critical for salivary gland fluid secretion, is regulated by bone morphogenetic protein 6. In- creased expression of this cytokine is strongly associated with the most common symptom of primary Sjögren’s syndrome, the loss of salivary gland function. This finding led us to develop a novel ther- apy in the treatment of Sjögren’s syndrome by increasing the water permeability of the gland to restore saliva flow. Our study demon- strates that the targeted increase of gland permeability not only resulted in the restoration of secretory gland function but also re- solved the hallmark salivary gland inflammation and systemic inflam- mation associated with disease. Secretory function also increased in the lacrimal gland, suggesting this local therapy could treat the sys- temic symptoms associated with primary Sjögren’s syndrome.

IgG Autoantigen Array using sera from primary Sjogren's syndrome patients and non-Sjogren's syndrome controls

Project description:Sera were acquired from the Sjogren's International Collaborative Clinical Alliance (SICCA) biorepository and were assayed for IgG autoantibodies. The autoantigen array was performed to identify the specific autoantibodies that were enriched in pSS patients.

Transcription profiling by array of parotid tissue from Primary Sjögren’s Syndrome and controls

Project description:Primary Sjögren’s syndrome (pSS) is a chronic autoimmune disease with complex etiopathogenesis. Here we use Affymetrix U133 plus 2.0 microarray gene expression data from human parotid tissue. Parotid gland tissues were harvested from 17 pSS and 14 14 non-pSS sicca patients and 18 controls. The data were used in the following article: Nazmul-Hossain ANM, Pollard RPE, Kroese FGM, Vissink A, Kallenberg CGM, Spijkervet FKL, Bootsma H, Michie SA, Gorr SU, Peck AB, Cai C, Zhou H, Horvath S, Wong DTW (2012) Systems Analysis of Primary Sjögren’s Syndrome Pathogenesis in Salivary Glands: Comparative Pathways and Molecular Events in Humans and a Mouse Model. Parotid gland tissues were harvested from 17 pSS and 14 non-pSS sicca patients and 18 controls.

Epigenetic regulation during the pathologic process from human primary Sjögren’s syndrome to mucosa-associated lymphoid tissue lymphoma

Project description:Primary Sjögren’s syndrome (pSS) is a systemic autoimmune disease characterized by reduced activity of the exocrine glands (principally the salivary and lacrimal glands) due to chronic lymphocytic infiltration. pSS has been closely associated with an enhanced risk of mucosa-associated lymphoid tissue (MALT) lymphoma. However, the dynamic epigenetic changes in gland cells accompanied with this pathogenesis are not fully understood. In present study, the labial gland (LG) and parotid gland (PG) tissues from two pSS patients with lymphoma were harvested including LG with negative antinuclear antibodies (ANA) and LG with positive ANA at the first diagnosis of pSS, as well as PG with and without lymphoma tissues at the second diagnosis of MALT. RNA-seq of these tissues were studied. This data is benefit to advanced understanding the dynamic development of MALT from pSS, emphasizing the importance of epigenetic alterations in regulating transcription during the pathologic process.

ChIP-seq of H3K4/9/27/36/79me3 were performed.

Gene expression analysis of total B, CD4+ T and epithelial cells in lacrimal glands from the NOD mouse model of Sjogren's syndrome

Project description:Despite being one of the most common rheumatologic diseases, there is still no disease-modifying drug for primary Sjögren’s syndrome (pSS). Advancing our knowledge of the target tissue has been limited by the low dimensionality of histology techniques and the small size of human salivary gland biopsies. The goal of this study was to characterize the gene expression profile of total B cells, CD4+ T cells and epithelial cells in the target tissue of the most commonly-used model of pSS (the NOD model of pSS characterized by severe dacryoadenitis developing in males between 8 and 16 weeks of age).

Proteomics of saliva, plasma, and salivary gland tissue in Sjögren’s syndrome and non-Sjögren patients identify novel biomarker candidates

Project description:Objective: The aim of this study was to characterize and compare the proteome in whole saliva, plasma, and salivary gland tissue in patients with primary Sjögren’s syndrome (pSS) and patients having symptoms of pSS, but not fulfilling the classification criteria, and to search for diagnostic biomarker candidates for pSS. Methods: Liquid chromatography tandem mass spectrometry was conducted on whole saliva, plasma, and labial salivary gland tissue samples from 24 patients with pSS and 16 non-Sjögren control subjects (non-pSS). Gene Ontology (GO)-terms and Kyoto Encyclopedia of Genes and Genomes (KEGG)-pathways were applied for functional annotation. Results: 1,013 proteins were identified in whole saliva, 219 in plasma, and 3,166 in salivary gland tissue. In saliva, 40 proteins differed significantly between the two groups. In pSS, proteins involved in immunoinflammatory processes were upregulated, whereas proteins related to salivary secretion were downregulated. The combination of neutrophil elastase, calreticulin, and tripartite motif-containing protein 29 yielded a receiver-operating characteristic (ROC) value of 0.97 (CI 0.93-1.00). Protein expression in plasma and salivary gland tissue did not differ between the patient groups. Conclusion: The salivary proteome of patients with pSS differed from that of non-pSS patients, indicating that saliva proteomics represents a promising non-invasive diagnostic tool for pSS.
