(Submitter supplied) Global DNA hypomethylation in CD4+ cells in SLE patients was suggested to play a key role in the pathogenesis. To identify new methylation-sensitive genes, we integrated genome-wide DNA methylation and mRNA profiling in CD4+ cells of MRL/lpr (MRL) and C57BL6/J (B6) mice. We identified Ctse, in which 13 methyl-CpGs within 583 bp region of intron 1 were hypomethylated, and mRNA upregulated in MRL compared with B6 mice. more...

(Submitter supplied) To identify any differentially expressed miRNAs in the CD4+ T cells of lupus. 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 human lupus. By using high-throughput microRNA profiling analysis, we identified that two miRNAs (miR-21 and miR-148a) overexpressed in CD4+ T cells from both lupus patients and lupus-prone MRL/lpr mice,which promote cell hypomethylation by repressing DNA methyltransferase 1 (DNMT1) expression.

(Submitter supplied) Systemic lupus erythematosus (SLE) damages multiple organs by producing various autoantibodies. Insufficient interleukin-2 (IL-2) production causes decreased regulatory T cells and permits expansion of autoreactive T cells in the development of SLE. We here show that decreased miR-200a-3p causes IL-2 hypoproduction through directly recruiting ZEB1 or ZEB2 and CtBP2 (ZEB1/ZEB2-CtBP2) complex in SLE T cells. more...

(Submitter supplied) Our previous study demonstrated a significant upregulation of a large set of miRNAs at the genomic imprinted Dlk1-Dio3 locus in lymphocytes of diverse murine lupus-prone strains. The upregulation of Dlk1-Dio3 miRNAs in lupus-prone mice is correlated with the global DNA hypomethylation. In this study, by performing genome-wide DNA methylation analysis, we reported that Dlk1-Dio3 genomic region in CD4+ T cells of MRL/lpr mice was hypomethylated, further linking hypomethylation to the increased expression of Dlk1-Dio3 miRNAs in lupus. more...

(Submitter supplied) This study performed Illumina Methylation450 analysis of CD4+ T-cells, CD19+ B-cells and CD14+ Monocytes from lupus patients and controls. A validation cohort was further analyzed with the same platform using CD4+ T-cells, CD45RO-CD45RA+ naive T-cells, CD45RO+CD45RA- memory T-cells, and CD25+CD127- regulatory T-cells.

(Submitter supplied) Our study has demonstrated that significant number of differential genes in SLE was involved in IFN, TLR signaling pathways and inflammatory cytokines. The enrichment of differential genes has been associated with aberrant DNA methylation, which may be relevant to the pathogenesis of SLE. Our observations laid the groundwork for further diagnostic and mechanistic studies of SLE and LN.

(Submitter supplied) Systemic lupus erythematosus (SLE) is a chronic-relapsing autoimmune disease of incompletely understood etiology. Recent evidence strongly supports an epigenetic contribution to the pathogenesis of lupus. To understand the extent and nature of dysregulated DNA methylation in lupus T cells, we performed a genome-wide DNA methylation study in CD4+ T cells from 12 lupus patients and 12 normal healthy controls. more...

(Submitter supplied) Lung CD4+ T cell responses may determine outcomes in pediatric pnuemonia. We therefore sought to define the transcriptional response and underlying DNA methyaltion landscape of lung CD4+ T cells by treating neonatal (~5 days of age) and juvenile (~15 days of age) mice with 2.8 million CFUs of E. coli or PBS (control) by aspiration. 48 hours later, lung CD4+ T cells were isolated by magnetic bead pre-enrichment and fluorescence-activated cell sorting for RNA-sequencing (RNA-seq) and modified reduced representation bisulfite sequencing (mRRBS).
