Dendritic cells (DCs) are critical to initiate the immune response and maintain tolerance, depending on different status and subsets. The expression profiles of microRNAs (miRNAs) in various DC subsets and haematopoietic stem cells (HSCs), which generate DCs, remain to be fully identified. Here we examine miRNomes of mouse bone marrow HSCs, immature DCs, mature DCs and IL-10/NO-producing regulatory DCs by deep sequencing. We identify numerous stage-specific miRNAs and histone modification in HSC ...[more]

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.

Batf3 maintains Irf8 autoactivation for commitment of a novel clonogenic progenitor of CD8+DCs

Project description:The transcription factors Batf3 and IRF8 are required for development of CD8α+ conventional dendritic cells (cDCs), but the basis for their actions was unclear. Here, we identify two novel Zbtb46+ progenitors that separately generate CD8α+ and CD4+ cDCs and arise directly from the common DC progenitor (CDP). Irf8 expression in the CDP depends on prior PU.1-dependent autoactivation, and specification of pre-CD8 DC progenitors requires IRF8 but not Batf3. However, upon pre-CD8 DC specification, Irf8 autoactivation becomes Batf3-dependent at a CD8α+ cDC-specific enhancer containing multiple AP1-IRF composite elements (AICEs) within the Irf8 superenhancer. CDPs from Batf3-/- mice that specify toward pre-CD8 DCs fail to complete CD8α+ cDC development due to decay of Irf8 autoactivation, and divert to the CD4+ cDC lineage. Examination of histone modifications (H3K27ac and H3K4me1) and 2 transcription factors (Batf3 and Irf8) and the p300 co-factor binding in 3 different dendritic cell subsets

microRNA atlas of dendritic cell (DC) development

Project description:We determined the microRNA profile of conventional DCs, plasmacytoid DCs, in vitro derived conventional DCs, and DC precursors in the bone marrow. We then compared conventional DCs to plasmacytoid DCs, conventional DCs and in vitro conventional DCs. In addition, we used MDS analysis to compare all the profiles. 14 profiles were produced. Duplicates of LSKs, CMPs, CLPs, CDPs, conventional DCs, plasmacytoid DCs, in vitro cDCs were sequenced.

Proteome and phophoproteome analysis of distinct dendritic cell maturation states

Project description:Depending on their environment and their exposure to various factors, dendritic cells (DCs) exist in different activation and maturation states. The versatility of DCs allows them to shape the immune system towards an inflammatory or tolerant state depending on the antigens and the environment they encounter. In this study we aimed to provide a proteomic catalogue of differentially expressed and differentially phosphorylated proteins between distinct DC maturation states, brought about by bacteria that differ in their endotoxicity. To achieve this, we have performed unlabeled shotgun proteomics and phosphoproteomics on cell fractions obtained from murine bone marrow DC cultures. The symbiont B. vulgatus stimulation was used to obtain semi-mature DCs, and the pathobiont E. coli stimulation was used to obtain mature DCs. For both shotgun proteome and phosphoproteome analysis two biological replicates consisting of 8 mice were used. Each biological replicate were run as 3 technical replicates.

In vivo LPS responses in murine splenic CD8 and CD11b DC subsets

Project description:Background: Dendritic cells (DCs) are critical for regulating CD4 and CD8 T cell immunity, controlling Th1, Th2, and Th17 bias, generating inducible Tregs, and inducing tolerance. Multiple DC subsets have been identified in the mouse that are thought to have evolved to control these different immune outcomes. However, how these subsets differentially respond to inflammatory and/or tolerogenic signals in order to accomplish their divergent functionality remains unclear. Results: We analysed the responses of murine, splenic CD8 and CD11b DC subsets to in-vivo stimulation with lipopolysaccharide using RNA-Seq and systems biology approaches and observed responses are highly subset-specific. We reanalysed multiple datasets from the literature and show that these subset responses are obscured when analysing signaling at the population level. We show that the subset-specificity is due to the unique regulation of distinct TLR4 pathway modulators that ‘fine-tune’ a common TLR4 cascade rather and not due to major differences in signaling pathways or transcription factors. Conclusions: We propose the Pathway Modulation Model wherein common signaling pathways are regulated by unique sets of modulators allowing for distinct immune responses in closely related DC subsets. We extend these observations using analagous datasets from the literature and show that our model provides a global mechanism for generating cell subset-specific signaling in multiple subpopulations in mouse and man. Splenic CD8 and CD11b DC subsets from LPS stimulated (10 pooled animals) and Control (5 pooled animals) mice were analysed by RNA-Seq.
