Transcription profiles of WT or MST1/2-KO total, CD8+ and CD8- DCs in vivo

Project description:CD8+ DCs play key role in CD8+ T cell priming, however, the underlying signaling mechansim is unclear. We used a data-driven network-based systems biology approach and identified Hippo signaling kinases as key selective modualtors in CD8+ DCs. We focused on Mst1/Stk4 to further investigate the novel function of Hippo signaling in CD8+ DCs. All transcriptional profies were evalated by microarray. 1) We used microarrays of total DCs in previous (GSE98481) and current studies to reverse engineer a DC-specific signaling interactome (DCI). 2) We integrated DCI with profiles of sorted CD8+ with CD8- DCs to identify signaling drivers of CD8+ DCs. 3) We profiled and compared Mst1/2-KO with WT cells from total, CD8+ and CD8- DCs to understand the mechanism of Mst1 in CD8+ DCs.

The Hippo kinase MST1 negatively regulates the differentiation of follicular helper T cells

Project description:In order to explore the regulatory mechanism of MST1 kinase on Tfh differentiation and function, we sorted Tfh cells in the spleen of WT and Mst1 KO mice 8 days after intraperitoneal sensitization, and extracted total RNA from the collected cells as samples for sequencing analysis.

Transcriptional profile of WT, PRR and IFN-/- dendritic cells stimulated with poly IC in vivo

Project description:Analysis of the specific transcriptional changes on DCs provided by direct pattern recogition receptor (PRR) or IFNAR signaling that are required for DC maturation after poly IC stimulation. Results provide important information about the intricate differentiation process of DC maturation and the importance of type I IFNs for DC immunogenicity. WT/IFNA-/- or WT/PRR-/- mixed-chimera mice were injected with 50 ug Poly-IC i.p. in vivo 4 and 14 hr later, wild type and KO CD11chi CD3- DX5- B220- DCs were FACS sorted based on CD45.2 expression. Total RNA was isolated and expression profile was compared between unstimulated and activated WT and KO DCs.

Human CD1c+ dendritic cells drive the differentiation of CD103+ CD8+ mucosal T cells via TGF-?

Project description:In comparison to murine dendritic cells (DCs), less is known about the function of human DCs in tissues. Here, we analyzed, using lung tissues from humans and humanized mice, the role of human CD1c+ and CD141+ DCs in determining the type of CD8+ T cell immunity to live-attenuated influenza virus (LAIV) vaccine. We found that both lung DC subsets acquired influenza antigens in vivo and expanded specific cytotoxic CD8+ T cells in vitro. However, lung-tissue-resident CD1c+ DCs but not CD141+ DCs were able to drive CD103 expression on CD8+ T cells and promote CD8+ T cell accumulation in lung epithelia in vitro and in vivo. CD1c+ DCs induction of CD103 expression was dependent on membrane-bound TGF-?1. Thus, CD1c+ and CD141+ DCs generate CD8+ T cells with different properties, and CD1c+ DCs specialize in the regulation of mucosal CD8+ T cells. Total RNA were isolated from purified human CD1c+ (BDCA1+) and CD141+ (BDCA3+) mDCs sorted from different tissues, including human blood, spleen and lungs of humanized mice, and human lungs. Eighteen samples in total were analyzed from different donors and tissues.

Gene expression comparison among spleen dendritic cells, brain microglia, brain dendritic cells and bone marrow monocytes

Project description:To understand the functional relationship between brain dendritic cells (brain DCs) and other myeloid cells, we compared the gene expression profile of m/chDCs to that of bone marrow monocytes, brain microglia and classical spleen CD8+ and CD8- DCs. In order to obtain enough brain DCs for mRNA extraction, we expanded brain DCs with in vivo Flt3L treatment before purification. This study includes data from FACs Aria-purified brain DCs, bone marrow monocytes, brain microglia and classical spleen CD8+ and CD8- DCs. The genearray was performed to compare expression of cell surface endocytic receptor, cytokine receptors, TLRs, transcription factors, molecules for antigen processing and presentation. Each Series consists of 3 individuall samples

Expression data from in vitro derived dendritic cells generated in the presence of FLT3-L from wt and miR-142-/- BM cells

Project description:2 types of dendritic cells (DCs) can be generated in vitro in the presence of Flt3-L: CD4+ equivalent CD24- DCs and CD8+ equivalent CD24+ DCs. miR-142-/- mice show a severe defect in the generation of CD4+ equivalent CD24- DCs. To understand the underlying mechanism, RNA expression was analyzed by Affymetrix microarray from the 2 in vitro subtypes of DCs derived from miR-142+/+ and miR-142-/- bone marrow cells. We used microarrays to detail the global programme of gene expression in the presence or absence of miR-142 in in vitro derived DCs. Bone marrow cells from miR-142+/+ and miR-142-/- C57Bl/6 mice were isolated and incubated in the presence of Flt3-L for 8 days. in vitro derived wt and ko dendritic cells were devided into CD4+ and CD8+ equivalent DCs by FACS and sorted with a FACS-Aria. RNA was isolated and gene expression was investigated

Effect of loss of PKC theta and p50+cRel on gene expression post T-cell stimulation

Project description:OT-1 Transgenic CD8 T-cells were isolated from spleens of WT, PKCθ theta KO, and p50 cRel DKO mice. The T-cells were either cultured with non-pulsed DC (WT only and signified as "WT - UN") or with BMDCs pulsed with the OVA peptide SIINFEKL (N4) (WT, PKCθ theta KO, and p50 cRel DKO and signified as 'genotype - N4') at a ratio of 1:10 (DC:T-cell) for 18 hours. DCs then were depleted from the culture and RNA was made from the T-cells to measure gene expression at the early / late stage of T-cell activation

Hippo kinases Mst1 and Mst2 sense and amplify IL-2R−STAT5 signaling in Treg cells to establish stable regulatory activity

Project description:Interleukin-2 (IL-2) and downstream transcription factor STAT5 are important for maintaining regulatory T (Treg) cell homeostasis and function. Tregs can respond to low levels of IL-2, but the mechanisms by which STAT5 is activated during partial IL-2 deficiency remain uncertain. We identified the serine-threonine kinase Mst1 as a signal-dependent amplifier of IL-2−STAT5 activity in Tregs. Tregs had high Mst1 and Mst2 (Mst1−Mst2) activity that was crucial to prevent tumor resistance and autoimmunity. Mechanistically, Mst1−Mst2 sensed IL-2 signals to promote the STAT5 activation necessary for Treg cell homeostasis and lineage stability, and maintain the highly suppressive phophorylated-STAT5+ Treg cell subpopulation. Unbiased quantitative proteomics revealed an association of Mst1 with the cytoskeletal DOCK8−LRCHs module that shaped activity Rho-family GTPase Rac activity, which in turn mediated STAT5 activation in Tregs. Collectively, IL-2−STAT5 signaling critically depends upon Mst1−Mst2 functions to maintain a stable Treg cell pool and immune tolerance. We used microarrays to compare the global transcription profiles of WT and Mst1/Mst2-null Treg cell populations
