(Submitter supplied) Dendritic cells (DCs) are a complex group of cells which play a critical role in vertebrate immunity. They are subdivided into conventional DC (cDC) subsets (CD11b and CD8alpha in mouse) and plasmacytoid DCs (pDCs). Natural killer cells are innate lymphocytes involved in the recognition and killing of abnormal self cells, including virally infected cells or tumor cells. DCs and NK cells are activated very early upon viral infections and regulate one another. more...

(Submitter supplied) The injection of the pathogen-associated molecular pattern Polyinosinic-polycytidylic acid (poly(I:C)) leads to the activation of various immune cells, including dendritic cells (DCs) and Natural Killer (NK) cells. This activation is due to different innate cytokines produced early after injection, in particular IFN-I. The objective of the study was to compare the pattern of expression of IFN-I stimulated genes between DC and NK cells. more...

(Submitter supplied) Murine Cytomegalovirus (MCMV) infection leads to the activation of various immune cells, including dendritic cells (DCs) and Natural Killer (NK) cells. This activation is partly driven by innate cytokines including IFN-I, which are induced early after infection. The objective was to address the role of different innate cytokines in shaping DC subsets and NK cell responses, in particular the role of cell intrinsic responses to IFN-I. more...

(Submitter supplied) The goal of this experiment was to use global gene expression profiling to assess the global genetic reprogramming of different types of splenic mononuclear phagocytes early after MCMV infection in vivo. This study includes new samples (GSM3178486-GSM3178497; available below) profiling splenic CD11b+ conventional dendritic cells (cDC2), classical monocytes (cMo) and red pulp macrophages (RPM) from untreated or day 1.5 MCMV-infected mice together with re-analysis of previously published data in order to examine the similarities in the pDC gene expression profiles across datasets. more...

(Submitter supplied) Plasmacytoid dendritic cells (pDC) are the major source of type I interferons (IFN-I) during viral infections, in response to triggering of endosomal Toll Like Receptors (TLR) 7 or 9 by viral single-stranded RNA or unmethylated CpG DNA, respectively. IFN-I production in pDC occurs in specialized endosomes encompassing preformed signaling complexes of TLR7 or 9 with their adaptor molecule MyD88 and the transcription factor interferon regulatory factor 7 (IRF7). more...

(Submitter supplied) Cytokine signaling via signal transducer and activator of transcription (STAT) proteins is crucial for optimal antiviral responses of natural killer (NK) cells. However, the pleiotropic effects of both cytokine and STAT signaling preclude the ability to precisely attribute molecular changes to either source. In this study, we employ a multi-“omics” approach to deconstruct and rebuild the complex interaction of three major STAT signaling pathways in NK cells. more...

(Submitter supplied) Type I interferons are critical anti-viral cytokines during virus infections and have also been implicated in the pathogenesis of systemic lupus erythematosus (SLE). The secretion of type I interferon of pDCs is modulated by Siglec-H, a DAP12 associated receptor on pDCs. We showed that Siglec-H deficient pDCs produce more of the type I interferon IFN-α in vitro and that Siglec-H ko mice produce more IFN-α after murine cytomegalovirus (mCMV) infection in vivo, leading to efficient clearance of the virus. more...

(Submitter supplied) Natural killer (NK) cells are innate lymphocytes that have been recently appreciated to display features of adaptive immunity in response to viral infection. Biallelic mutations in the IRF8 gene have been reported to cause familial NK cell deficiency and susceptibility to severe viral infection in humans; however, the precise role of this transcription factor in regulating NK cell function remained unknown. more...

(Submitter supplied) Natural killer (NK) cells are innate lymphocytes that possess features of adaptive immunity such as clonal expansion and generation of long-lived memory. Here we look at transcriptional profiles of NK cells throughout several time points during MCMV infection, ex-vivo cytokine stimulation, and/or deficiency of key transcription factors such as STAT4, STAT1, and Runx1. In addition, we profile parallel time points of MCMV-specific CD8 T cells during infection and memory formation.

(Submitter supplied) The ability of dendritic cells (DCs) to activate immunity is linked to their maturation status. In prior studies we have shown that selective antibody-mediated blockade of inhibitory FcgRIIB receptor on human DCs in the presence of activating immunoglobulin (Ig) ligands leads to DC maturation and enhanced immunity to antibody-coated tumor cells. Here we show that Fcg receptor (FcgR) mediated activation of human monocytes and monocyte-derived DCs is associated with a distinct gene expression pattern, including several inflammation associated chemokines as well as type 1 interferon (IFN) response genes including the activation of signal transducer and activator of transcription 1 (STAT1). more...

(Submitter supplied) Purpose: Controlling the balance between immunity and immunopathology is crucial for host resistance to pathogens. Upon infection, activation of the hypothalamic-pituitary-adrenal (HPA) axis leads to the production of glucocorticoids (GCs). However, the pleiotropic effects of these steroid hormones make it difficult to decipher their precise role in vivo. Our purpose was to study how GCs regulate the function of group 1 ILCs in spleen and liver upon Murine Cytomegalovirus (MCMV) infection. more...

(Submitter supplied) The aim of the project is to characterize the heterogeneity of murine plasmacytoid dendritic cells (pDCs) and to decipher their activation trajectory during a viral infection in vivo. To this end, individual splenic pDCs were transcriptionally profiled at ground state and at the time of their peak production of type I interferon (IFN-I) during mouse cytomegalovirus infection, with enrichment of IFN-I-producing pDCs based on the use of a reporter mouse strain and on their down-regulation of LIFR.

(Submitter supplied) Plasmacytoid dendritic cells (pDC) are the major source of type I and type III interferons (IFN-I/III) during viral infections, in response to triggering of endosomal Toll Like Receptors (TLRs) 7 or 9 by viral single-stranded RNA or unmethylated CpG DNA, respectively. Interestingly, this function is restricted to a minor fraction of pDC (Zucchini et al. Int. Immunol. 2008). In this project, we aimed at identifying the molecular pathways involved in inducing IFN-I/III production in this minor faction of pDC during in vivo infection by the mouse cytomegalovirus (MCMV). more...
