Project description:Investigating differential gene expression between clinical phenotypes in primary Sjögren's Syndrome using matched healthy controls as a further comparator group. Samples are derived from the UK Primary Sjögren's Syndrome Registry (UKPSSR)
Project description:We compared subsets of B cells as follows: Bm1 cells; CD38-IgD+, naïve B cells; CD38+IgD+, pre-germinal centre B cells; CD38highIgD+ and memory B cells; CD38±IgD that were collected from patients with primary Sjögren's syndrome. As a result, list of 623 differentially expressed genes was created. We found interferon signature genes and HLA genes were mostly up-regulated in patients compared to healthy controls.
Project description:A causal mediation analysis of DNA methylation as a mediator of nearby genetic association with Sjögren's syndrome using data collected from 131 female members of the Sjögren's International Collaborative Clinical Alliance registry, comprising of 64 Sjögren's syndrome cases and 67 non-cases.
Project description:Sjögren's syndrome is an autoimmune disease manifesting primarily as dryness of eyes and mouth. In this study, we compared gene expression in PBMCs between age- and gender-matched patients with Sjögren's syndrome (diagnosed by ACR criteria) and healthy controls. Cells were collected in heparinized tubes and PBMCs were prepared using Ficoll.
Project description:To elucidate gene expression signatures of liver induced by Sjögren's syndrome, we have employed whole genome microarray expression profiling as a discovery platform.
Project description:Labial gland tissues were obtained from three individuals diagnosed with pSS and three healthy donors. All participants were recruited from the Rheumatology and Immunology Department of Kunshan First People's Hospital during 2022.
Project description:Genome wide DNA methylation profiling of human labial salivary gland (LSG) biopsy samples obtained from 28 female members of the Sjögren's International Collaborative Clinical Alliance (SICCA) Registry. The Illumina HumanMethylation450 BeadChip platform was used to obtain DNA methylation profiles across more than 450,000 highly informative CpG sites. Samples included 15 non-case glands, and 13 glands from patients with Sjögren's Syndrome.
Project description:We report that bone marrow derived macrophages from our Sjögren's syndrome mouse model exhibit an elevated inflammatory response to both apoptotic cells and TLR stimuli according to RNA-Seq data and pathway anyalysis
