Identification of VIMP/SELS as a gene inhibiting cytokine production in human CD4+ effector T cells

ABSTRACT: Many players regulating the CD4+ T cell-mediated inflammatory response have already been identified. However, the critical nodes that constitute the regulatory and signaling networks underlying CD4 T cell responses are still missing. Using a correlation-network-guided approach, here we identified VIMP (VCP-interacting membrane protein, also known as SELS), one of the 25 genes encoding selenoproteins in humans, as a gene regulating the effector functions of human CD4 T cells, especially production of several cytokines including IL2 and CSF2. We identified VIMP as an endogenous inhibitor of cytokine production in CD4 effector T cells via both, the E2F5 transcription regulatory pathway and the Ca2+/NFATC2 signaling pathway. Our work not only indicates that VIMP might be a promising therapeutic target for various inflammation-associated diseases, but also shows that our network-guided approach can significantly aid in predicting new functions of the genes of interest.

C/EBPβ regulates lipid metabolism and Pparg isoform 2 expression in alveolar macrophages

Project description:Pulmonary alveolar proteinosis (PAP) is a syndrome characterized by accumulation of surfactant lipoproteins within the lung alveoli. Alveolar macrophages (AMs) are crucial for surfactant clearance and their differentiation depends on colony-stimulating factor 2 (CSF2) and the establishment of an AM-characteristic gene regulatory network. Here we report that the transcription factor C/EBPβ is essential for the development of the AM identity, as demonstrated by transcriptome and chromatin accessibility analysis. Furthermore, C/EBPβ-deficient AMs showed severe defects in proliferation, phagocytosis and lipid metabolism, collectively resulting in a PAP-like syndrome. Mechanistically, the long C/EBPβ protein variants LAP* and LAP together with CSF2 signaling induced expression of Pparg isoform2, but not isoform1, a molecular regulation that was also observed in other CSF2-primed macrophages. These results uncover C/EBPβ as a key regulator of AM cell fate and as the missing link between CSF2 and Pparg isoform 2 expression, thereby regulating lipid turnover in AMs.

Profiling of human CD4+ T subsets identifies a Th2-specific non-coding RNA GATA3-AS1

Project description:Host defense against diverse pathogens involves the recruitment and differentiation of CD4+ T effector subsets including T helper 1 (Th1), Th2, Th17 and induced regulatory T (Treg) cells. Surface phenotype studies have revealed subset-specific surface markers for the identification and purification of human primary CD4+ T effector subsets. In the present study, we aimed to characterize the mRNA and large intergenic non-coding RNA (lincRNA) expression differences between human primary CD4+ T effector subsets and identify potential subset-specific genes. To achieve this goal, mRNA and lincRNA microarray profiling of flow cytometry-sorted human primary Th1, Th2, Th17 and Treg cells was performed. Principal component and pathway analyses revealed subset-specific gene expression patterns. A Th2-specific lincRNA, GATA3-AS1, also termed FLJ45983, was identified in primary immune cells and tissues, as well as in in vitro polarized CD4+ T effector subsets. Further analysis showed that GATA3-AS1 was a potential diagnostic marker in allergy, a Th2-associated disease. This first systematic genome-wide analysis of gene expression differences between primary CD4+ T effector subsets may help to identify novel regulatory protein-coding genes and lincRNAs regulating CD4+ T cell subset differentiation, as well as potential diagnostic markers. As an example, we identified a GATA3-associated Th2-specific marker lincRNA GATA3-AS1. Gene expression microarray analysis of flow-cytometry sorted human primary naÃ¯ve CD4+ T cells, CD4+ T central memory cells, Th1, Th2, Th17 and Treg cells from buffy coat of four healthy controls Gene expression microarray analysis was performed using SurePrint G3 Human Gene Expression 8X60K microarray.

Blimp-1 and c-Maf regulate common and unique immune gene networks to protect against distinct pathways of pathobiont-induced colitis [scRNA-Seq]

Project description:Using single-cell RNA-seq of colon lamina propria leukocytes (LPL), together with ATAC-seq, ChIP-seq and RNA-seq from colon LPL and sorted CD4+ T from colon lamina propria during oral infection with the pathobiont Helicobacter hepaticus we show that Blimp-1 and c-Maf both positively regulate Il10 gene expression, but also cooperate to negatively regulate a large network of proinflammatory effector genes in T cells. While T cell-specific deletion of either Prdm1, Maf or both transcription factors did not result in overt inflammation of the colon at steady state, H. hepaticus infection resulted in mild/moderate colitis in both the Prdm1fl/flCd4Cre and Maffl/flCd4Cre single T cell-specific transcription factor deficient mice, while the double knockout Prdm1fl/flMaffl/flCd4Cre infected mice suffered severe colitis and showed a massive increase in T cell effector genes in colonic LPL. Blimp-1 and c-Maf cooperate to negatively regulate genes including Ifng, Csf2, Il23r, Stat4, Il18r1 and Il2rg, and deletion of both these transcription factors in T cells translated to an exacerbated pathogenic TH1, IFN-g+GM-CSF+ effector cell response. c-Maf, additionally negatively regulated Il17a expression which was elevated in the LPL as assessed by bulk RNA-seq and scRNA-Seq analysis in the H. hepaticus infected Maffl/flCd4Cre mice.

Time-series microRNA profiling of in-vitro differentiated human CD4+T-cells

Project description:Differentiation of CD4+T-cells into effector subsets is a critical component of the adaptive immune system and an incorrect response can lead to autoimmunity or immune deficiency. Cellular differentiation including T-cell differentiation is accompanied by large-scale transcriptional changes, including expression of microRNAs involved in suppressing mRNA expression. We combined time-series microRNA and mRNA expression to construct a CD4+T-cell microRNA/mRNA regulatory network and identified 25 subnetworks (modules) which were associated with multiple T-cell related diseases. This dataset was designed to assess how microRNA expression changes over time during human CD4+T-cell differentiation and used to construct a microRNA/mRNA regulatory network. Matching mRNA expression profiling is available in E-GEOD-60678.

RNAi knock down of VCP in human HeLa cells

Project description:Study of the effects of the VCP knockdown. VCP (p97, yeast cdc48) is a hexameric AAA ATPase involved in various cellular functions including degradation of proteins by the ubiquitin-proteasome system. We examine the consequences of the reduction of VCP levels after RNAi of VCP in HeLa cells. We find ~30 transcripts upregulated in a sequence independent manner. Those transcripts encode proteins involved in endoplasmic reticulum stress, apoptosis, and amino acid starvation.
