Cytokine expression in macrophages and splenic CD4+ T-cells

ABSTRACT: This experiment was designed to study the cytokine gene expression profile of macrophage under 50uM DU exposure. the experiment was repeated three time, with duplicate spots for each gene on the array. Conclusion: DU exposure induces the expressions of IL-10, NF-kBP65, and Midkine and other cytokine genes, indicating the immunomodulation abilities of DU. (GSM43230-GSM43241) This experiment was designed to study the cytokine gene expression of splenic CD4+ T-cells under 100uM DU exposure in 24 hours. Conclusion: DU induces Th2 cytokine gene expression (eg. IL-5), and midkine, as well as other cytokine genes, indicating the abilities of DU in promoting Th2 shifting during differtiation.

In vitro immune toxicity of depleted uranium: effects on murine macrophages, CD4+ T cells, and gene expression profiles.

Wan Bin B Fleming James T JT Schultz Terry W TW Sayler Gary S GS

Environmental health perspectives 20060101 1

Depleted uranium (DU) is a by-product of the uranium enrichment process and shares chemical properties with natural and enriched uranium. To investigate the toxic effects of environmental DU exposure on the immune system, we examined the influences of DU (in the form of uranyl nitrate) on viability and immune function as well as cytokine gene expression in murine peritoneal macrophages and splenic CD4+ T cells. Macrophages and CD4+ T cells were exposed to various concentrations of DU, and cell d ...[more]

DUSP10 constrains innate IL-33-mediated cytokine production in ST2hi memory-type pathogenic Th2 cells

Project description:Memory CD4+ T helper (Th) cells are crucial for acquired immunity and protection from infectious microorganisms, and also drive pathogenesis of chronic inflammatory diseases, such as asthma. ST2hi memory-type Th2 cells have been identified as a pathogenic subpopulation capable of directly inducing eosinophilic airway inflammation. These ST2hi pathogenic Th2 cells produce large amounts of IL-5 upon stimulation via their TCR, but not in response to IL-33. In contrast, IL-33 alone induces cytokine production in ST2+ group 2 innate lymphoid cells (ILC2). We investigated the molecular mechanism that controls the innate function of IL-33-induced cytokine production, and identified a MAPK phosphatase Dusp10, as a key negative regulator of IL-33–induced cytokine production in Th2 cells. We found that Dusp10 is expressed by ST2hi pathogenic Th2 cells but not by ILC2, and Dusp10 expression inhibits IL-33-induced cytokine production by preventing GATA3 activity through inhibition of p38 MAPK phosphorylation. Strikingly, deletion of Dusp10 rendered ST2hi Th2 cells able to directly respond to IL-33 exposure and produce IL-5. Thus, DUSP10 constrains IL-33–induced cytokine production in ST2hi pathogenic Th2 cells by controlling p38-mediated GATA3 function.

The Effect of Steroid and ERa agonism on Th2 cells

Project description:Allergic asthma is a T helper 2 (Th2) cell-associated inflammatory disease, driven by cytokines such as IL-4, IL-5, and IL-13. Th2 cells express the G-protein-coupled receptor CRTh2, a receptor for prostaglandin D2 (PGD2) that influences Th2 function and survival. Inhaled glucocorticosteroids are the primary treatment of allergic asthma and improve asthma symptoms by inhibiting Th2 cytokine production. Women are more likely than men to have severe asthma and to have symptoms requiring a hospital visit. These findings lead us to consider a mechanism by which female sex hormones could influence Th2 cell response to glucocorticosteroid. Using whole-mRNA sequencing, we examined gene expression in primary Th2 cells following exposure to glucocorticosteroids (0.1µM) in the presence or absence of an estrogen mimic, PPT (10µM).

Genome-wide analysis of mouse macrophages stimulated with IL-4 (bone marrow macrophages) (Affymetrix)

Project description:Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from bone marrow derived macrophages upon exposure to 20 ng/ml of IL-4 for 18 hours. Bone marrow derived macrophages were stimulated with the Th2 cytokine IL-4, for RNA extraction and hybridization on Affymetrix microarrays.

Genome-wide analysis reveals unique regulation of transcription of Th2-specific genes by GATA3

Project description:Differentiation of naive CD4 T cells into type 2 helper (Th2) cells is accompanied by chromatin remodeling and increased expression of a set of Th2-specific genes including those encoding Th2 cytokines. IL-4-mediated STAT6 activation induces high levels of transcription of GATA3, a master regulator of Th2 cell differentiation, and enforced expression of GATA3 induces Th2 cytokine expression. However, it remains unclear whether the expression of other Th2-specific genes is induced directly by GATA3. A genome-wide unbiased ChIP-seq analysis revealed that GATA3 bound to 1,279 genes selectively in Th2 cells, and 101 genes in both Th1 and Th2 cells. Simultaneously, we identified 26 highly Th2-specific STAT6-dependent inducible genes by a DNA microarray analysis-based three-step selection processes, and among them 17 genes showed GATA3 binding. We assessed dependency on GATA3 for the transcription of these 26 Th2-specific genes, and 10 genes showed increased transcription in a GATA3-dependent manner while 16 genes showed no significant responses. The transcription of the 16 GATA3-nonresponding genes was clearly increased by the introduction of an active form of STAT6, STAT6VT. Therefore, although GATA3 has been recognized as a master regulator of Th2 cell differentiation, many Th2-specific genes are not regulated by GATA3 itself but in collaboration with STAT6. Th1 and Th2 subsets are profiled for mRNA expression Examination of GATA3-binding and 3 different histone modifications in Th1 and Th2 cells.

Identification of a new pathway for Th1 cell development induced by cooperative stimulation with IL-4 and TGFbeta [Agilent]

Project description:IL-4 plays an important role in the induction of Th2 and Th9 cells as well as in the inhibition of Th1 cell generation. We herein show that a combination of IL-4 and TGFbeta augment the development of Th1 cells that express CD103 (CD103+ Th1 cells) if IFNgamma is present. The T-box containing transcription factor, eomesodermin (Eomes) is preferentially expressed in CD103+ Th1 cells, and is involved in IFNgamma production. The induction of T-bet during early T cell activation is essential for the formation of the active chromatin at both the Eomes and IFNgamma gene loci. TGFbeta is required for the induction of Eomes and CD103, as well as the inhibition of Th2 cytokine expression. In addition, IL-4 induces Eomes transcription through activation of the Stat6 signaling pathway. IFNgamma-producing CD103+ Th1 cells are detected in the IEL of normal mice, and their numbers significantly decrease in Tbet- and Stat6-deficient mice. These results represent the first molecular mechanism of IL-4/TGFbeta-dependent augmentation of Th1 cell generation, and raise the possibility that IL-4 and TGFbeta may simultaneously enhance the Th1 cell-mediated immune responses under certain cytokine conditions. Th9+IFNgamma and Th9 cells are profiled for mRNA expression

Cytokine receptor modulation by interleukin-2 broadly regulates T helper cell lineage differentiation

Project description:T helper (Th) cells control host defense to pathogens. IL 12R expression is required for Th1, IL-4RM-NM-1 for Th2, and IL-6RM-NM-1/gp130 for Th17 differentiation to allow responsiveness to IL-12, IL-4, and IL-6, respectively. IL-2 via STAT5 controls Th2 differentiation by regulating the Th2 cytokine gene cluster and Il4ra expression. Here we show that IL-2 regulates Th1 differentiation, inducing STAT5-dependent IL-12RM-NM-22 and T-bet expression, with impaired human Th1 differentiation when IL-2 was blocked. Th1 differentiation was also impaired in mouse Il2-/- T cells but restored by IL-12RM-NM-22 expression. Consistent with IL-2M-bM-^@M-^Ys inhibition of Th17 differentiation, IL-2 decreased Il6ra and Il6st/gp130 expression, and Il6st augmented Th17 differentiation even when IL-2 was present. Thus, IL-2 influences T-cell differentiation by modulating cytokine receptor expression to help specify/maintain differentiated states. Genome-wide mapping of STAT1,STAT4,STAT5A,STAT5B binding to their target genes in Th1 or human CD4+ cells was conducted

Single-cell and bulk RNA-seq of Th2

Project description:Th2 cell is a subset of CD4+ T helper (Th) cells, which regulates the immunity to extracellular parasites and allergic inflammation. Th2 cells specifically secrete Type 2 cytokines such as IL-4, IL-5, IL-13, and also express many universal cytokines like IL-2 and GM-CSF. While theses cytokines are indispensable for Th2 cell mediated response, there is complex heterogeneity in the pattern of cytokine production among Th2 cell population. As previous studies were mainly conducted at population levelref, here we took advantage of single-cell RNA-seq to explore heterogeneity in in vitro differentiated Th2 cells. Although a few single cell researches about Th2 cells was conducted, there is no comprehensive understanding of the heterogeneity of Th2 lineage yet, inspiring us to make some difference on this issue. Our studies identify that cytokine genes contributed most to the transcriptome heterogeneity of Th2 cells; expression of universal cytokines showed bimodality, but not Th2 specific cytokines.
