IRF5 genetic risk variants drive myeloid-specific IRF5 hyper-activation and pre-symptomatic SLE

ABSTRACT: The IRF5-SLE risk haplotype is associated with SLE disease severity. We hypothesized that neutrophils from healthy risk donors would carry a pathogenic gene signature compared to non-risk donors. To compare basal neutrophil gene signature between risk and non-risk healthy individuals, fresh whole blood was collected from healthy donors, and granulocytes were extracted from the remaining pellet following Ficoll purification. RNA-seq libraries were prepared from globin-reduced RNA extracted from the granulocytes using the Qiagen RNA preparation kit.

Transcriptome analysis of peripheral blood from Lyn-deficient mouse SLE model lacking Ifnar1 or Irf5

Project description:To clarify the role of interferon regulatory factor 5 (IRF5) other than inducing type I interferons (IFNs) in the pathogenesis of systemic lupus erythematosus (SLE), we performed transcriptome analysis of peripheral blood from Lyn-deficient mice with concomitant Ifnar1 or Irf5 deficiency. The results of gene set enrichment analysis (GSEA) suggest that IRF5 is involved in the induction of not only IFN-inducible genes (ISGs) but also oxidative phosphorylation (OXPHOS)-related genes in the SLE pathogenesis.

Genome-wide profiling of target genes for the systemic lupus erythematosus-associated transcription factors IRF5 and STAT4

Project description:IRF5 and STAT4 are strongly associated with human systemic lupus erythematosus (SLE). By performing chromatin immunoprecipitation-sequencing (ChIP-Seq) in human peripheral blood mononuclear cells (PBMCs), we identified more than 7000 target genes for IRF5 and STAT4 in stimulated PBMCs. Contrarily, without stimulation IRF5 seemed to be inactive, and STAT4 only showed low levels of transcriptional regulatory activity. Target genes of IRF5 and STAT4 were identified in human PBMCs with or without stimulation using ChIP-Seq.

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.

Gene expression profiling in wild-type, Irf5-KO, Lyn-KO and Lyn/Irf5-DKO BMDCs unstimulated or stimulated with CpG-B ODN

Project description:To characterize the relationship between IRF5 and Lyn in innate immune responses at a genome-wide scale, we performed gene expression microarray analysis for wild-type (WT), Irf5-KO, Lyn-KO and Lyn/Irf5-DKO bone marrow-derived dendritic cells (BMDCs) with or without 6 h-stimulation with 150 nM CpG-B ODN. We extracted the transcripts that were upregulated by CpG-B ODN in WT BMDCs, further upregulated in Lyn-KO BMDCs and then downregulated in Lyn/Irf5-DKO BMDCs (fold change â?¥ 2, false discovery rate < 0.05). When these 79 transcripts were sorted by their expression levels in Lyn-KO BMDCs, most of the top 20 genes (13 out of 20) were those encoding type I interferons (IFNs), indicating that Lyn particularly suppresses IRF5 induction of type I IFNs. BMDCs from WT, Irf5-KO, Lyn-KO and Lyn/Irf5-DKO mice in a C57BL/6 background were unstimulated or stimulated with CpG-B ODN. Biological triplicate for each genotype were analyzed (24 samples in total).

Genome-wide maps of chromatin state of IRF5+/+ and IRF5-/- CD4+ mouse T cells

Project description:Genetic variants in IRF5 are associated with multiple immune-mediated diseases. IRF5 has been predominantly focused on for its regulation of myeloid-derived cells. We found that IRF5 contributes to CD4+ T cell outcomes and that it regulates early T cell receptor-initiated signaling and subsequently translocates to the nucleus where it binds to promoters of various genes regulated with T cell activation. We report the chromatin state of freshly isolated and activated IRF5+/+ and IRF5-/- CD4+ T cells in vitro. While there are minimal differential peaks between freshly isolated IRF5+/+ and IRF5-/- CD4+ T cells, once activated multiple differential peaks are observed between IRF5+/+ and IRF5-/- CD4+ T cells.

Transcriptional profiles of pediatric SLE neutrophils and Healthy neutrophils cultured with SLE sera or Interferon

Project description:Mature neutrophis were freshly isolated from blood of pediatric systemic lupus erythematosus (SLE) patients and healthy donors. Illumina microarray was used to assess transcriptional changes between SLE group and Control group. To uderstand further the gene expression difference between SLE and healthy neutrofils, neutrophils from healthy donors were cultured with autologous sera, SLE sera or Interferon and microarray data was used to compare with fresh SLE neutrophils. (Expt 1) Neutrophils from 21 SLE samples (19 patients) and 12 healthy donors were isolated, and extracted RNAs were used generate microarray data. (Expt 2) Neutrophils isolated from 2 healthy children (not used in the first experiment) were cultured with autologous sera (control), Interferon alpha (100U and 1000U), and 4 SLE sera and 6 SLE sera for 6 hours and RNAs were extract for microarray experiment.
