Project description:Gene expression profile was compared between CD8+CD122+ T cells and CD8+CD122- T cells. mRNA taken from CD8+CD122+ cells or CD8+CD122- cells collected by cell sorting from C57BL/6 mice spleen was amplified and analyzed by using gene chip of Agilent.

Project description:We show that Ly49+CD122+ CD8+ Treg have a distinct expression profie compared to conventional Foxp3+ CD4+ Treg and CD49 lo CD122+ CD8 effector like cells. RNA was extracted from sorted cells and sent for sequencing

Project description:The maintenance of immune homeostasis requires regulatory T cells (Tregs). Given their intrinsic self-reactivity, Tregs must stably maintain a suppressive phenotype to avoid autoimmunity. We report that impaired expression of the transcription factor (TF) Helios by FoxP3+ CD4 and Qa-1-restricted CD8 Tregs results in defective regulatory activity and autoimmunity in mice. Helios-deficient Treg develop an unstable phenotype during inflammatory responses characterized by reduced FoxP3 expression and increased effector cytokine expression secondary to diminished activation of the STAT5 pathway. CD8 Treg also require Helios-dependent STAT5 activation for survival and to prevent terminal T cell differentiation. Definition of Helios as a key transcription factor that stabilizes regulatory T-cells in the face of inflammatory responses provides a genetic explanation for a core property of regulatory T-cells. We used microarrays to detail the global programs of gene expression by CD8 Treg (CD44+CD122+Ly49+) and conventional memory type of CD8 cells (CD44+CD122+Ly49-).

Project description:The close functional relationship between macrophages and dendritic cells has long been recognised. Here, we have examined the gene expression profiles of splenic macrophages and the splenic resident dendritic cell subsets, and demostrate that macrophages and DC show different gene expression profiles. Further, we show that the DC subsets are closer to one another in gene expression profile than they are to macrophages. We here identify a list of differentially expressed genes between the DC subsets, and between DC and macrophages Splenic macrophages, CD8+ and CD8- cDC were analyzed

Project description:Transcriptional profiling of mouse in-vitro derived CD8+ cells (obtained after culturing BM-HSCs isolated from B6 mice) with OP9-DL1 cells for 35 days were compared to CD8+ thymocytes isolated from 4-5 weeks old B6 mice. Our goal was to determine similarities and differences in gene expression profile between in vitro-derived CD8+ cells and CD8+ cells isolated from the thymus. The procedure of in vitro differentiation of HSC using OP9-DL1 cocultures was previously described by: Schmitt, T. M., and J. C. Zuniga-Pflucker. 2002. Induction of T cell development from hematopoietic progenitor cells by delta-like-1 in vitro. Immunity 17:749-756 and Holmes, R., and J. C. Zuniga-Pflucker. 2009.

Biological replicates: 2 different samples of in vitro-derived CD8+ T cells from day 35 were compared to 2 different samples of thymic CD8+ cells.

Project description:The peri-bronchial zone of chronic obstructive pulmonary disease (COPD) is the site of extensive infiltration of immune cell, allowing persistent contacts between resident cells and immune cells. Tissue fibrocytes interaction with CD8+ T cells and its consequences were investigated. We show that fibrocytes and CD8+ T cells are found in vicinity in distal airways and that potential interactions are more frequent in tissues from COPD patients compared to those of control subjects. Increased proximity and clusterization between CD8+ T cells and fibrocytes are associated with altered lung function. Tissular CD8+ T cells from COPD patients promote fibrocyte chemotaxis via the CXCL8-CXCR1/2 axis. CD8+ T cells establish short-term interactions with fibrocytes, that trigger CD8+ T cell proliferation in a CD54- and CD86-dependent manner, pro-inflammatory cytokines production, CD8+ T cell cytotoxic activity and fibrocyte immunologic signaling. We defined a computational model describing these intercellular interactions and calibrated the parameters based on our experimental measurements. We showed the model’s ability to reproduce histological ex vivo characteristics, and observed major contributions of fibrocyte-mediated CD8+ T cell proliferation and fibrocyte death in COPD development. Using the model to test therapeutic scenarios, we predicted a recovery time of several years, and the failure of targeting independently chemotaxis or interacting processes. Altogether, our study reveals that local interactions between fibrocytes and CD8+ T cells can occur in vivo and could jeopardize the balance between protective immunity and chronic inflammation in bronchi of COPD patients.

Project description:Analyzing and comparing proteome and phosphoproteome profiling between CD8+ DC and CD8- DC not only will be very helpful to understand the molecular mechanisms regulating CD8+/- DC differentiation and function but also can screen CD8+ or CD8- DC specific regulatory pathways or molecules.

Project description:Thymocyte-thymocyte interaction can be very efficiently occur in CIITAtgpIV-/- mouse. We analyzed the gene expression profile between CD8+ T cells generated in CIITAtgpIV-/- mouse, and compared it to that of CD8+ T cells from B6 WT mouse. In this dataset, we include the expression data obtained from CD8 single positive thymocytes generated in CIITAtgpIV-/- mouse and B6 WT mouse. These data are used to obtain 279 genes that showed differentially increased expression in CIITAtgpIV-/- mouse.
