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.

miRNAs expression in kidney tissues of systemic lupus erythematosus (SLE) individuals

Project description:MicroRNAs (miRNAs) have been implicated as fine-tuning regulators controlling diverse biological processes at the level of posttranscriptional repression. Dysregulation of miRNAs has been described in various disease states, including inflammatory autoimmune diseases. By using high-throughput microRNA profiling analysis, we identified a series of miRNAs dysregulated in local inflammatory lesions of human patients with autoimmune diseases such as SLE. We isolated the renal biopsy samples from eight SLE patients as well as tumor adjacent kidney tissues from four kidney cancer patients as controls for comparison. Total RNA was extracted for the TaqManM-BM-. Low Density Assay v3.0

Transcriptomic signature in patients with systemic lupus erythematosus (SLE) [T cells]

Project description:T cell abnormalities are well-known features of patients with systemic lupus erythematosus (SLE). The role of CD4 and CD8 T lymphocytes, however, remains poorly understood with data suggesting both protective and deleterious roles. This project aimed to identify a cell-specific transcriptional signature in patients with SLE that could be used as a prognostic disease marker. The overall objective is to correlate the clinical presentation with specific RNA signatures to determine if there are signatures that correlate with disease outcome

Autoantibody profiling of sera from individuals with Systemic Lupus Erythematosus (SLE) by protein microarray

Project description:We developed a protein microarray to identify autoantigens in Systemic Lupus Erythematosus (SLE). Baculovirus-Sf9 cell expression system was used to create a protein microarray with 1543 full-length human proteins expressed with a biotin carboxyl carrier protein (BCCP) folding tag. We assayed sera from UK and USA SLE individuals (total n=277), age/ancestry matched control cohorts (n=280) and a confounding disease cohort (n=92).

A single cell approach to map cellular subsets involved in Systemic Lupus Erythematosus (SLE) heterogeneity

Project description:In this study, we analyzed the transcriptomes of ~276k single PBMCs from 33 childhood SLE (cSLE) and 11 healthy matched donors (cHD). Our findings were validated in an independent cohort including 8 adult SLE (aSLE) patients and 6 matched controls (aHD; ~132k PBMCs).
