Sex-based comparison of CD4+ T cell DNA methylation patterns in SLE reveals pro-inflammatory epigenetic changes in men

ABSTRACT: Male patients with systemic lupus erythematosus (SLE) experience severe disease compared to female patients, despite the disease being more prevalent in females. For the time, we compared genome-wide differential methylation in CD4+ T cells between male (n=12) and female (n=10) SLE patients.

LC-MS of PBMC in SLE and healthy control

Project description:Systemic Lupus Erythematosus (SLE) is a systemic autoimmune disease that displays a significant gender difference in terms of incidence and severity. However, the underlying mechanisms accounting for sexual dimorphism remain unclear. To reveal the heterogeneity in the pathogenesis of SLE between male and female patients. PBMC were collected from 15 patients with SLE (7 males, 8 females) and 15 age-matched healthy controls (7 males, 8 females) for proteomic analysis. Enrichment analysis of proteomic data revealed that type I interferon signaling and neutrophil activation networks mapped to both male and female SLE, while male SLE has a higher level of neutrophil activation compared with female SLE. Our findings define gender heterogeneity in the pathogenesis of SLE and may facilitate the development of gender-specific treatments.

Gene expression in RNP autoantibody+ systemic lupus erythematosus (SLE) patient blood

Project description:The goal of this study was to characterize gene expression profiles in RNP autoantibody+ SLE versus healthy blood donors with a focus on select cytokines that may be important in B cell activation and differentiation, including BAFF, IL-21, and IL-33. We utilized Affymetrix microarrays to characterize the global program of gene expression in the SLE patients, and to identify differentially expressed genes in patients compared to healthy controls. We examined a cohort of 79 consecutive patients classified as anti-ribonuclear protein (anti-RNP)+ systemic lupus erythematosus (SLE). All patients provided RNA samples obtained after providing informed consent. There were 73 female and 6 male subjects. Disease duration ranged from 0 to 453 months with a median of 37.5 months. SLE Disease Activity Index (SLEDAI) ranged from 0 to 31 with a median of 6. mRNA from the blood of a SLE cohort (79 patients with some repeat visits for a total of 99 arrays) and 30 healthy volunteers (one array per volunteer) were analyzed.

RNA-seq of peripheral blood mononuclear cell (PBMC) derived from normal healthy donors and systemic lupus erythematosus (SLE) patients

Project description:Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease. There is no cure for SLE. The mechanism involves an immune response by autoantibodies against a person's own tissues. However, the mechanism underlying imbalance of autoantibodies is not clear. In this experiment, peripheral blood was obtained from normal healthy donors and systemic lupus erythematosus (SLE) patients. Peripheral blood mononuclear cells (PBMC) were separated by Ficoll separation solution. Samples of four (total eight) donors were pooled and Samples of four (total eight) SLE patients were pooled. The aim was to characterize the mRNA profile of SLE patients compared to healthy donors and find the new target of diagnosis or treatment for SLE.

Proteomic profiling of healthy and SLE isolated B-cells

Project description:B cells orchestrate the autoimmune responses in patients with systemic lupus erythematosus (SLE), but broad based B-cell directed therapies only show modest efficacy while attenuating humoral immune responses to vaccines and inducing acquired immunodeficiency. used proteomic and transcriptomic analyses of B cells from patients with SLE and healthy individuals and demonstrated a dominant DDR in SLE B cells.

Activation of the Interferon Pathway is Dependent upon Autoantibodies in African-American SLE Patients, but not in European-American SLE Patients

Project description:Systemic lupus erythematosus (SLE) is a heterogeneous disease which leads to different levels of serum autoantibodies to RNA-binding proteins (anti-RBP) and interferon-Î± (IFN-Î±), which plays an important pathogenic role in SLE, between European-American (EA) and African-American (AA) patients. We aimed to explore how IFN-related gene expression pathways differ in patients according to their ancestry and anti-RBP profile Whole blood from 33 female SLE patients and 16 matched controls from EA and AA ancestral backgrounds was analyzed through Affymetrix Gene 1.0 ST gene expression arrays and the data were further studied through Ingenuity Pathways Analysis for canonical pathway comparison. An independent replication cohort of more than 100 SLE patient samples and 30 controls was used to test the hypotheses generated by the microarray data, using qPCR to quantify gene expression.

Changes in the Pattern of DNA Methylation Associate with Twin Discordance in SLE

Project description:This is the first high-throughput analysis of DNA methylation in autoimmune diseases. We have used a cohort of MZ twins discordant for three diseases whose clinical signs often overlap: systemic lupus erythematosus (SLE), rheumatoid arthritis and dermatomyositis. Only MZ twins discordant for SLE featured widespread changes in the DNA methylation status of a significant number of genes. Individual analysis confirmed the existence of DNA methylation and expression changes in genes relevant to SLE pathogenesis. Our findings not only identify potentially relevant DNA methylation markers for the clinical characterization of SLE patients but also support the notion that epigenetic changes may be critical in the clinical manifestations of autoimmune disease. Total DNA isolated by standard procedures from 59 White Blood Cell (WBC) samples corresponding to monozygotic twins discordant for three different autoimmune diseases: systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and dermatomyositis (DM) and two additional controls for each MZ twin pair.
