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

ABSTRACT: 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.

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 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.

Expression analysis of murine splenic B-cells after retroviral transduction with a constitutively active variant of IRF5 (IRF5-4D)

Project description:Genome-wide gene expression analysis of murine splenic B-cells following retroviral transduction with a constitutively active IRF5 (IRF5-4D) Illumina WG-6 v2.0 arrays were hybridized to determine the gene expression profile of murine splenic B-cells following retroviral transduction with i) control virus (MSCV-IRES-CFP) or ii) IRF5-4D virus (MSCV-IRF5-4D-CFP). All hybridizations were done in biological triplicates.

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).

Expression analysis of Reh cells after transfection with constitutively active variants of IRF5 (IRF5-4D) and/or constitutively active IKKÎ²(EE)

Project description:Genome-wide gene expression analysis of Reh cells following transfection with constitutively active IRF5-4D, constitutively active IKKÎ²(EE), or both in combination. Affymetrix U133 Plus 2.0 oligonucleotide arrays were hybridized to determine the gene expression profile of acute lymphoblastic leukemia-derived Reh cells following transfection with i) control constructs, ii), a constitutively active variant of IRF5 (IRF5-4D), iii) a constitutively active variant of the IkB kinase Î² (IKKÎ²(EE)), or iv) IRF5-4D in combination with IKKÎ²(EE). All hybridizations were done in biological duplicates.

TASL is the SLC15A4-associated adaptor for IRF5 activation by TLR7–9

Project description:Toll-like receptors (TLRs) have a crucial role in the recognition of pathogens and initiation of immune responses. Here we show that a previously uncharacterized protein encoded by CXorf21—a gene that is associated with systemic lupus erythematosus—interacts with the endolysosomal transporter SLC15A4, an essential but poorly understood component of the endolysosomal TLR machinery also linked to autoimmune disease. Loss of this type-I-interferon-inducible protein, which we refer to as ‘TLR adaptor interacting with SLC15A4 on the lysosome’ (TASL), abrogated responses to endolysosomal TLR agonists in both primary and transformed human immune cells. Deletion of SLC15A4 or TASL specifically impaired the activation of the IRF pathway without affecting NF-κB and MAPK signalling, which indicates that ligand recognition and TLR engagement in the endolysosome occurred normally. Extensive mutagenesis of TASL demonstrated that its localization and function relies on the interaction with SLC15A4. TASL contains a conserved pLxIS motif (in which p denotes a hydrophilic residue and x denotes any residue) that mediates the recruitment and activation of IRF5. This finding shows that TASL is an innate immune adaptor for TLR7, TLR8 and TLR9 signalling, revealing a clear mechanistic analogy with the IRF3 adaptors STING, MAVS and TRIF. The identification of TASL as the component that links endolysosomal TLRs to the IRF5 transcription factor via SLC15A4 provides a mechanistic explanation for the involvement of these proteins in systemic lupus erythematosus.

Assessing chromatin accessibility in WT and STAT4-/- ILC1s

Project description:STAT4 dynamically interacts with the genomic landscape and functions in modulating chromatin accessibility to influence gene expression. We aimed to evaluate the impact of STAT4 on chromatin accessibility of colonic lamina propria ILC1s. To address this aim, we sorted ILC1s from the colonic LP of unmanipulated C57BL/6 and STAT4-/- mice and performed the assay for transposase-accessible chromatin using sequencing (ATAC-seq).
