Effects of TNF-alpha blocking in sorted Th17 cells from co-cultures of human CD4-positive and CD14-positive cells

ABSTRACT: Human CD4+ T cells and CD14+ monocytes from healthy donors were co-cultured with anti-CD3 for three days in the presence or absence of TNF-alpha mAb (Adalimumab). Classical Th17 cells (Th17) or those generated in the presence of the inhibitor (iTh17) were then sorted and analyzed by full transcriptome microarray analysis.

Effects of TNF-alpha blocking in sorted Th17 cells from co-cultures of human CD4-positive and CD14-positive cells

Project description:Human CD4+ T cells and CD14+ monocytes from healthy donors were co-cultured with anti-CD3 for three days in the presence or absence of TNF-alpha mAb (Adalimumab). Classical Th17 cells (Th17) or those generated in the presence of the inhibitor (iTh17) were then sorted and analyzed by full transcriptome microarray analysis. A total of 18 samples consisting of paired samples from 9 healthy volunteers were compared. Sorted Th17 cells from co-cultures containing either Adalimumab (1 microgram/ml) or not were obtained from each of the donors, and compared by full transcriptome profiling.

Characterization of microRNA signature in activated CD4+ T, polyclonal Th17 (Th17 poly), OVA-specific Th17 (Th17 Ag-sp) cell skewed cultures

Project description:To determine specific miRNAs for Th17 cells, we performed comparative miRNA screening of activated CD4+ T, polyclonal Th17 (Th17 poly) and OVA-specific Th17 (Th17 Ag-sp) cell skewed cultures or Th17 Ag-sp sorted cells. The expression of miRNAs analyzed by microarray revealed 27 miRNAs exclusively expressed in culture or sorted Th17 Ag-sp cell subset.

CIP2A negatively regulates Th17 differentiation

Project description:Interleukin 17 (IL-17) producing T helper 17 (Th17) cells are critical drivers of pathogenesis in a variety of autoimmune and inflammatory diseases. Strategies to mitigate excessive Th17 response thus remain an attractive target for immunotherapies. Here we report that Cancerous Inhibitor of Protein Phosphatase 2A (CIP2A) regulates IL-17 production by Th17 cells in human and mouse. Using CIP2A knock-out (KO) mice and siRNA-mediated CIP2A silencing in human primary CD4+ T cells, we demonstrated that CIP2A silencing results in a significant increase in IL-17 production. Interestingly, CIP2A deficient Th17 cells were characterized by increased strength and duration of STAT3 (Y705) phosphorylation. Genome-wide gene expression profile as well as the p-STAT3 (Y705) interactome of CIP2A deficient Th17 cells identified that CIP2A regulates the strength of the interaction between Acylglycerol kinase (AGK) and STAT3, and thereby, modulates STAT3 phosphorylation as well as expression of IL-17 in Th17 cells. Our results uncover the physiological function of CIP2A in Th17 cells and provides new opportunities for therapeutic intervention in Th17 cell mediated diseases.

Mouse Th17 T cells, IL-23 stimulated

Project description:Interleukin 23 (IL-23) triggers pathogenic features in pro-inflammatory, IL-17-secreting T cells (Th17 and Tγδ17) that play a key role in the development of inflammatory diseases. However, the IL-23 signaling cascade remains largely undefined. Here we used quantitative phosphoproteomics to characterize IL-23 signaling in primary murine Th17 cells. We quantified 6,888 phosphorylation sites in Th17 cells, and found 168 phosphorylations regulated upom IL-23 stimulation. IL-23 increased the phosphorylation of the myosin regulatory light chain (RLC), an actomyosin contractibility marker, in Th17 and Tγδ cells. IL-23-induced RLC phosphorylation required JAK2 and ROCK catalytic activity, and the study of the IL-23/ROCK axis revealed an unexpected role of IL-23 in the migration of Tγδ17 and Th17 cells. Moreover, pharmacological inhibition of ROCK reduced Tγδ17 recruitment to inflamed skin upon challenge with inflammatory agent Imiquimod. This work: i) provides new insights into phosphorylation networks that control Th17 cells, ii) widely expands the current knowledge on IL-23 signaling, and iii) contributes to the increasing list of immune cells subsets characterized by global phosphoproteomic approaches.

Differentially expressed microRNAs in antigen-specific Th17 cell cultures from WT and CD69KO mice

Project description:To explore miRNA signature in T cells during moderate (wild type BALB/c) and severe (cd69-/- in BALB/c background) EAM development, we performed microarray experiments with OVA-specific Th17 (Th17 Ag-sp) cell skewed cultures. The comparison of miRNA profiles from Th17 Ag-sp subsets of cd69-/- and wild type mice, with severe and mild EAM respectively, revealed a number of deregulated miRNAs.

LKB1/STK11-sensing of mitochondrial function controls Th17 cell responses

Project description:T helper 17 (Th17) cells are a distinct subset of CD4+ T cells necessary for maintaining gut homeostasis and have prominent roles in autoimmunity and inflammation. Th17 cells have unique metabolic features, including a stem cell-like signature and reliance on mitochondrial respiratory chain function and tricarboxylic acid (TCA) cycle to coordinate metabolic and epigenetic remodeling. Dynamic changes in mitochondrial membrane morphology are key to sustain organelle function. However, it remains unclear whether mitochondrial membrane remodeling orchestrates metabolic and differentiation events in Th17 cells. Here we demonstrate that mitochondrial membrane fusion and tight cristae organization are required for Th17 cell function (i.e. cytokine expression). As a genetic model system we employ Th17 specific deletion of optic atrophy 1 (OPA1), a gene that encodes a protein involved in mitochondrial inner membrane fusion and cristae organization. As a result, we find that Th17 cells rely on mitochondrial fusion (due to their low metabolic activity). Here, we carry out DIA-based differential quantitative proteomic analysis of murine wild-type and OPA1 knock-out Th17 cells. Through Ingenuity pathway analysis and together with transcriptional and metabolomic profiling we identify the serine/threonine kinase liver associated kinase B1 (LKB1/STK11) as an essential node coupling mitochondrial function to IL-17A cytokine expression in T cells.
