TranscriptomicsGene expression profiling of splenic XCR1+ dendritic cells from untreated or day 1.5 MCMV-infected mice
The goal of this experiment was to use global gene expression profiling to assess the global genetic reprogramming of spleen XCR1+ DC early after MCMV infection in vivo, using on Affymetrix Mouse Gene 1.0 ST Array. Comparison of the gene expression programs of XCR1+ dendritic cells isolated from the...

TranscriptomicsA fraction of steady state splenic XCR1+ dendritic cells undergo an homeostatic maturation as assessed by their upregulation of CCR7 or of IL-12, and by their profound genetic reprogramming
XCR1+ dendritic cells (DC) have been shown to excel in antigen cross-presentation for the activation of naïve CD8 T cells. This property was reported to be associated to the subset of the XCR1+ DC expressing IL-12b upon ex vivo stimulation for 24 h with a mixture of CpG, IFN-γ, and GM-CSF (Lin ML ...

TranscriptomicsThymic XCR1+ dendritic cells undergo a functional maturation irrespective of type I interferon and of the microflora
Dendritic cells (DC) play critical roles in central and peripheral T cell tolerance. DC found in the steady-state periphery undergo an homeostatic, tolerogenic, maturation that promotes interaction with naive T cells and induction of abortive responses. In contrast, thymic DC are thought to exist so...

TranscriptomicsGene expression profiling of mouse spleen XCR1+ DC at steady state, 3 hours after polyI:C or 12 hours after STAg i.v. injection
The goal of this experiment was to use global gene expression profiling to compare the global genetic reprogramming of spleen XCR1+ DC upon in vivo stimulation with a viral-type ligand, polyI:C which strongly induces type I interferons, versus with a ligand derived from an intracellular parasite whi...

TranscriptomicsThymic XCR1+ dendritic cells undergo a functional maturation fundamentally similar to that of peripheral tolerogenic XCR1+ dendritic cells
Dendritic cells (DC) play critical roles in central and peripheral T cell tolerance. DC found in the steady-state periphery undergo an homeostatic, tolerogenic, maturation that promotes interaction with naive T cells and induction of abortive responses. In contrast, thymic DC are thought to exist so...

TranscriptomicsH3K9me3 Cut&Tag on hematopoietic stem cells sorted from mice 1 month after they were irradiated (2Gy total body irradiation = IR) or not (non irradiated = NIR) and with or without prior TNFa treatment (IR_TNF)
Analysis of the RNA-seq data performed in IR vs NIR hematopoietic stem cells show the loss of the TNF_via_NFKB signature. We showed that the loss of this signature could be associated with H3K9me3 loss at specific retrotransposable elements . To validate this association, we tested if TNFa treatment...

GenomicsH3K9me3 ChIP-seq on hematopoietic stem cells sorted from mice 1 month after they were irradiated (2Gy total body irradiation = IR) or not (non irradiated = NIR)
We aim at understanding how ionizing radiations (IR) increase the risk of developing myeloid leukemia. We recently showed that IR leads to the derepression of retroelements. We demonstrated that retroelements expression in aged HSCs is regulated by the heterochromatin repressive histone mark H3K9me3...

TranscriptomicsBroad and largely overlapping molecular changes arise in thymic and peripheral XCR1+ dendritic cells upon tolerogenic and immunogenic maturation [reanalyzed samples]
This series contains re-analyzed samples from GSE39555, GSE39556 and GSE15907. DC were isolated from lymphoid organs as previously described (Vremec et al., 2000). Normalized data are available on the SuperSeries record, GSE71171.
