Klf4 expression in conventional dendritic cells is required for T helper 2 cell responses

Project description:Subset-specific and progenitor gene expression analysis of Klf4+/+ and Klf4-/- DCs. The two major lineages of classical dendritic cells (cDCs) express and require either IRF8 or IRF4 transcription factors for their development and function. IRF8-dependent cDCs promote anti-viral and T-helper 1 (Th1) cell responses, whereas IRF4-expressing cDCs have been implicated in controlling both Th2 and Th17 cell responses. Here, we have provided evidence that Kruppel-like factor 4 (Klf4) is required in IRF4-expressing cDCs to promote Th2 but not Th17 cell responses in vivo. Conditional Klf4 deletion within cDCs impaired Th2 cell responses during Schistosoma mansoni infection, Schistosoma egg antigen (SEA) immunization, and house dust mite challenge (HDM), without affecting cytotoxic T lymphocyte (CTL), Th1 and Th17 cell responses to herpes simplex virus, Toxoplasma gondii and Citrobacter rodentium infections. Further, Klf4 deletion reduced IRF4 expression in pre-cDCs and resulted in selective loss of IRF4-expressing cDCs subsets in several tissues. These results indicate that Klf4 guides a transcriptional program promoting IRF4-expressing cDCs heterogeneity. Bone marrow progenitors and skin draining LN subsets were harvested from 4 Klf4fl/fl cre negative or Vav1-icre mice and were sorted to >95% purity on the FACS Aria 3.

Expression in LT-HSC after in vitro culture in mSCF, mTpo, mFlt3L, hIGFBP2 and Angptl5.

Project description:Mouse LT-HSC were sorted and cultured in mScf, mTpo, mFlt3L, hIGFBP2 and Angptl5 for 2 days. These expression values were related to insertions of gamma-retroviral, lentiviral or alpharetroviral vectors carrying GFP which were retrieved after serial murine BM transplantation. The relation between gene expression in the cells responsible for long-term hematopoiesis and location of vector integration was investigated. Biological duplicate measurements of murine sorted and cultured LT-HSC (LSK, CD34-, CD135-)

Dysregulated TLR7 signaling drives anemia via development of hemophagocytic macrophages

Project description:The debilitating autoimmune disease Systemic Lupus Erythematosus (SLE) is closely associated with Toll-like receptor (TLR) 7 and type I interferon (IFN) activity in humans and in murine SLE-like disease. Two central manifestations of SLE affect the myeloid lineage of the immune system, myeloid expansion and anemia. Yet, whether these symptoms are linked and the role of TLR7 and/or type I IFN in these processes is unclear. Here we show that TLR7 signaling promotes cell-autonomous, phosphoinositide 3-kinase (PI3K)- and mammalian target of rapamycin (mTOR)-dependent macrophage development from the common myeloid progenitor (CMP). Strikingly, this TLR7-driven macrophage development requires and is enhanced by type I IFN. Genome-wide transcriptional profiling and functional studies demonstrated that TLR7 promoted the expression of Spic, the master regulator of splenic red pulp macrophages (RPM) and preferential development of hemophagocytic RPM-like cells from CMP in vitro. We found increased incidence of RPM-like cells in vivo in a mouse model of SLE caused by TLR7 overexpression, which correlated with decreased red blood cell (RBC) count and anemia. These findings demonstrate a mechanism by which TLR7 signaling promotes anemia that is of clinical significance in SLE, other rheumatological diseases and chronic viral infections. This work also identifies a previously unknown molecular pathway by which TLR signaling and type I IFN synergize to promote myeloid development from hematopoietic progenitors. CMP were sorted from the bone marrow of wild-type C57BL/6 mice, cultured with SCF+R848 or SCFr+MCSF, and CD11b+F4/80+ macrophages sorted after 5 days, n=3 per group

Microarray analysis of WT ESAM+ and ESAM- cDC subsets

Project description:Defense against attaching and effacing (A/E) bacteria requires the sequential generation of IL-23 and IL-22 to induce protective mucosal responses. While the critical source of IL-22 has been identified as CD4+ and Nkp46+ innate lymphoid cells (ILCs), the precise source of IL-23 is unclear. Here, we use genetic techniques to deplete specific classical dendritic cell (cDC) subsets and analyze immunity to the A/E pathogen Citrobacter rodentium. We find that Zbtb46+ cDCs, and specifically Notch2-dependent intestinal CD11b+ cDCs, but not Batf3-dependent CD103+ cDCs, are required for IL-23 production and immunity against C. rodentium. Notch2 controls cDC differentiation at a terminal step mediated by lymphotoxin signaling. Importantly, these results provide the first demonstration of a non-redundant function of CD11b+ cDCs in vivo. Analysis of differentially expressed genes in ESAM+ and ESAM- CD11b+ and DEC205+ splenic classical DC subsets. Splenocytes were harvested from WT C57Bl/6 or WT Cx3cr1-gfp mice and cDC subsets sorted to >95% purity on the FACSAriaII.

Dendritic cell-derived IL-2 promotes apoptosis of terminally mature cells via a novel autocrine signaling pathway

Project description:Dendritic cells (DCs) are crucial for sensing pathogens and triggering immune response. GM-CSF myeloid dendritic cells (GM-DCs) secrete several cytokines including IL-2 upon activation by pathogen associated molecular pattern (PAMP) ligands. DC IL-2 has been shown to be important for innate and adaptive immune responses, however its importance in DC physiology has never been demonstrated. This is due to ambiguity in expression of the CD122 subunit of the IL-2 trimeric receptor complex crucial for signaling. We show here that autocrine IL-2 signaling is functional in GM-DCs in early time window of stimulation with PAMPs. IL-2 signaling selectively activates the JAK/STAT5 pathway by assembling holo-receptor complexs at the cell surface. Autocrine IL-2 signaling inhibits survival of PAMP matured GM-DCs which is crucial for maintaining immune tolerance and preventing autoimmunity. Our findings suggest immune regulation by a novel autocrine signaling pathway that can potentially be exploited in DC immunotherapy. Microarray technology was used to understand the role of IL-2 signaling in DC. Microarray was performed to investigate the role of IL-2 signaling in DC physiology. Hence Wt or IL-2-/- BMDCs were either treated or not with curdlan for 6h and taken for microarray.
