Transcriptional regulation of adaptive NK and CD8 T cell responses [RNA-Seq]

ABSTRACT: 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.

Transcriptional and epigenetic regulation of adaptive NK cell responses [ChIP-Seq]

Project description:Natural killer (NK) cells are innate lymphocytes that possess features of adaptive immunity such as clonal expansion and generation of long-lived memory. Interleukin (IL)-12 signaling through its downstream transcription factor STAT4 is required for the generation of memory NK cells following expansion, while type I interferon through STAT1 is important for NK cell expansion. Here, we identify gene loci that are highly enriched for STAT4 binding using ChIP-seq for STAT4 and the permissive histone mark H3K4me3 in activated NK cells. In addition, we identify gene loci that are high enriched for STAT1 binding in response to type I interferon signaling.

Transcription factor IRF8 orchestrates the adaptive natural killer cell response

Project description: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. Here, we show that IRF8 is required in a cell-intrinsic manner for NK cell-mediated protection against mouse cytomegalovirus (MCMV) infection. During exposure to MCMV, IRF8 is robustly upregulated in NK cells by IL-12 and STAT4, which promotes epigenetic remodeling of the Irf8 locus. Moreover, IRF8 facilitates the proliferative burst of virus-specific NK cells by promoting expression of a suite of DNA replication and cell cycle genes, and directly regulating Zbtb32, a master regulator of NK cell proliferation during viral challenge. These results identify a novel function and cell-type specific regulation for IRF8 in host antiviral immunity, and provide a mechanistic understanding of virus susceptibility in patients with IRF8 mutations.

STAT4 promotes Bhlhe40 induction to drive protective IFN-g from natural killer cells during viral infection [RNA-Seq]

Project description:NK cells represent a cellular component of the mammalian innate immune system, and mount rapid responses against viral infection, including the secretion of the potent anti-viral effector cytokine IFN-g. Following mouse cytomegalovirus (MCMV) infection, Bhlhe40 was the most highly induced transcription factor in NK cells among the basic helix-loop-helix family. Bhlhe40 upregulation in NK cells depended upon IL-12 and IL-18 signals, with the promoter of Bhlhe40 enriched for STAT4 and the permissive histone H3K4me3, and STAT4-deficient NK cells showing an impairment of Bhlhe40 induction and diminished H3K4me3. Transcriptomic and protein analysis of Bhlhe40-deficient NK cells revealed a defect in IFN-g production during MCMV infection, resulting in diminished protective immunity following viral challenge. Finally, we provide evidence that Bhlhe40 directly promotes IFN-g by binding throughout the Ifng loci in activated NK cells. Thus, our study reveals how STAT4-mediated control of Bhlhe40 drives protective IFN-g secretion by NK cells during viral infection.

Divergent role for STAT5 in the adaptive responses of natural killer cells

Project description:Natural killer (NK) cells are innate lymphocytes with the capacity to elicit adaptive features, including clonal expansion and immunological memory. Because signal transducer and activator of transcription 5 (STAT5) is essential for NK cell development, the role of this transcription factor and its upstream cytokines IL-2 and IL-15 during infection have not been carefully investigated. In this study, we investigate how STAT5 regulates transcription during viral infection. We demonstrate that STAT5 is induced in NK cells by IL-12 and STAT4 early after infection, and that partial STAT5 deficiency results in a defective capacity of NK cells to generate long-lived memory cells. Furthermore, we find a functional dichotomy of IL-2 and IL-15 signaling outputs during viral infection, whereby both cytokines drive clonal expansion, but only IL-15 is required for memory NK cell survival. We thus highlight a novel role for STAT5 signaling in promoting an optimal antiviral NK cell response.

Natural killer cell sensing of infected cells compensates deficient Toll-like receptor but not IFN-I activity for mouse resistance to cytomegalovirus

Project description:Plasmacytoid dendritic cells (pDC) are the major source of type I IFN (IFN-I) in vivo during Murine Cytomegalovirus (MCMV) infection. This response requires pDC-intrinsic MyD88-dependent signaling by Toll Like Receptors 7/9. Provided that they express appropriate recognition receptors such as Ly49H, Natural Killer (NK) cells can directly sense and kill MCMV-infected cells. While MyD88- and Ly49H-dependent responses can contribute to MCMV control, the objective is to understand the relative importance of these 3 mechanisms. In order to decipher the relative impact of MyD88- and Ly49H-dependent mechanisms during MCMV infection, we performed a genome-wide expression analysis on total spleen of Ly49H-/-MyD88+/+, Ly49H-/-MyD88-/-, Ly49H+/+MyD88+/+ and Ly49H+/+MyD88-/- BALB/c mice at different time points after MCMV infection (d0, d1,5, d2, d3 and d6). This study includes data from the spleen BALB/c mice, under steady-state or MCMV condition at different time points. 2 to 5 mice for each mouse strain for each time point were used, and were hybridized on 5 separate batches of gene chips.

Shared and distinct metabolic demands for innate and adaptive cytotoxic lymphocytes during viral infection

Project description:Natural Killer (NK) cells and CD8+ T cells share many characteristics at steady state and during viral infection. In this study, we interrogate the metabolic pathways that fuel NK cell effector function in response to mouse cytomegalovirus (MCMV) infection. This dataset contains transcriptional profiling of wild-type and LDHA-deficient Ly49Hpositive NK cells at steady state and early after infection.

Fate mapping of single NK cells identifies a type 1 innate lymphoid-like lineage that bridges innate and adaptive recognition of viral infection [scRNAseq_spleen_LN_total_NK]

Project description:Upon viral infection, NK cells expressing certain germline-encoded receptors are selected, expanded and maintained in an adaptive-like manner. Currently, these are thought to differentiate along a common pathway. However, by fate mapping of single NK cells upon murine cytomegalovirus (MCMV) infection, we identified two distinct NK cell lineages that contributed to adaptive-like responses. One was equivalent to conventional NK (cNK) cells while the other was transcriptionally similar to type 1 innate lymphoid cells (ILC1s). ILC1-like NK cells showed splenic-residency and strong cytokine production but also recognized and killed MCMV-infected cells, guided by activating receptor Ly49H. Moreover, they induced clustering of conventional type 1 dendritic cells and facilitated antigen-specific T cell priming early during MCMV infection, which depended on Ly49H and the NK cell-intrinsic expression of transcription factor Batf3. Thereby, ILC1-like NK cells bridge innate and adaptive viral recognition and unite critical features of cNK cells and ILC1s.
