Microarray analysis of WT ESAM+ and ESAM- cDC subsets

ABSTRACT: 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.

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.

The affect of specific ablation of Runx3 from Esam splenic dendritic cells

Project description:Esam/CD4+ dendritic cells are part of the innate immunity essential for priming and activating of CD4+ T cells To identify Runx3 responsive genes Esam dendritic cells were freshly sorted from macs enriched splenic DCs taken from 6 weeks old mice. Four samples from four mice were sorted and analyzed where in each littermates pair consisted of a control and Runx3 conditional KO. Mice lacking Runx3 specifically in the DC compartment were produced by crossing Runx3fl/fl mice onto CD11c-Cre mice. This mating scheme generated Runx3fl/fl/CD11c:Cre (CD11c-DC-Runx3Δ) mice.
