TranscriptomicsMicroarray analyses of lymph node dendritic cells (DCs) stimulated in vitro with papain or LPS
T helper type 2 (Th2) responses are induced by protease allergens and helminthes. However the molecular mechanisms that initiate Th2 responses are poorly understood. To obtain insight into this mechanism, we performed a microarray analysis of lymph node DCs stimulated in vitro with the protease alle...

TranscriptomicsTranscriptomes of monocyte-derives DCs stimulated with various compounds
Little is known about the early transcriptional events in innate immune signaling in immature and tolerogenic monocyte-derived dendritic cells (DCs), the professional antigen-presenting cells of our immune system. TLR ligands usually induce a proinflammatory transcriptional response, whereas IL10 an...

TranscriptomicsGene expression profiling of BDC2.5 CD4T cells isolated from NOD mice after in vivo antigen stimulation with either DEC205+ or DCIR2+ DCs.
We identified DCIR2+DCs but not DEC205+DCs as able to induce peripheral T cell tolerance in pre-diabetic autoimmune NOD mice. To determine what distinct genetic programs are elicited in the auto-reactive CD4 T cells early after stimulation by these two DC subsets, we utilized adoptive transfer of BD...

TranscriptomicsTranscriptome of inflammatory myeloid DCs in psoriasis
Background: Previous work has identified CD11c+CD1c- dendritic cells (DCs) as the major 'inflammatory' dermal DC population in psoriasis vulgaris and CD1c+ DCs as the 'resident' cutaneous DC population. Objective: To further define molecular differences between these two myeloid dermal DC populatio...

TranscriptomicsExpression data from NOD and C57BL/6 mouse pancreas CD8α- Dendritic Cells (DCs) under steady-state and after in-vitro LPS stimulation
Abstract Two major dendritic cell (DC) subsets have been described in the islets of mice: The immunogenic CD8α-CD11b+ DCs and the tolerogenic CD8α+CD103+ DCs. We have recently reported on reduced numbers of the minor population of tolerogenic CD8α+CD103+ DCs in the pancreas of 5 week old pre-dia...

TranscriptomicsTranscription profiling of human monocyte derived dendritic cells treated with DC-SIGN initiates an immature dendritic cell phenotype triggering Rho activation that is utilised by HIV-1
DC-SIGN is a C-type lectin expressed by dendritic cells (DCs) that binds HIV-1, sequestering it within multivesicular bodies to facilitate transmission to CD4+ T cells. Here we characterize the molecular basis of signalling through DC-SIGN by large-scale gene expression profiling and phosphoproteome...

TranscriptomicsSplenic CD8+ and CD8- DCs
Analysis of gene expressions in mouse splenic dendritic cells (DCs). DCs were purified into two subsets, CD8-positive and -negative ones. DCs were expanded in vivo by injecting Flt3L-producing tumors into the backs of C57BL/6 mice. To expand DCs in vivo, Flt3L-producing B16 melanoma cells were inje...

TranscriptomicsDC response to Respiratory syncytial virus from adult peripheral and cord blood
Respiratory syncytial virus (RSV) is a major cause of morbidity and mortality. Previous studies have suggested that T cell responses may contribute to RSV immunopathology, which could be driven by dendritic cells (DCs). DCs are productively infected by RSV, and during RSV infections, there is an inc...

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

TranscriptomicsTranscription profiling of murine dendritic cells in the presence and absence of interferon (IFN)-gamma to identify a tolerogenic signature in IDO-competent dendritic cells.
Although much is known on the transcriptional profiles of dendritic cells (DCs) during maturation, the molecular switches critical for the acquisition of a tolerogenic program by DCs are still obscure. In the present study, we explored the gene expression pattern of CD8+ DCs purified from the mouse ...
