Project description:The archetypal Th2 cytokine interleukin 4 (IL-4) has previously been shown to alternatively activate dendritic cells (DCs) both in vitro and in vivo.To more fully understand the impact of IL-4 dependent alternative activation of DCs, we used mRNA microarrays to define their transcriptional profile. RNAs were extracted from bone marrow-derived dendritic cells (BMDCs). Two groups of samples were taken, with three biological replicates in each: control untreated, and treated with recombinant-IL4 (at 20 ng/ml).

Project description:Because of their potent immunoregulatory capacity, dendritic cells (DCs) have been exploited as therapeutic tools to boost immune responses against tumors or pathogens, or dampen autoimmune or allergic responses. Murine bone marrow-derived DCs (BM-DCs) are the closest known equivalent of the blood monocyte-derived DCs that have been used for human therapy. Current imaging methods have proven unable to properly address the migration of injected DCs to small and deep tissues in mice and humans. This study presents the first extensive analysis of BM-DC homing to lymph nodes (and other selected tissues) after intravenous and intraperitoneal inoculation. Following intravenous delivery, DCs accumulated in the spleen, and preferentially in the pancreatic and lung-draining lymph nodes. In contrast, DCs injected intraperitoneally were found predominantly in peritoneal lymph nodes (pancreatic in particular), and in omentum-associated lymphoid tissue. This uneven distribution of BM-DCs, independent of the mouse strain and also observed within pancreatic lymph nodes, resulted in the uneven induction of an immune response in different lymphoid tissues. These data have important implications for the design of systemic cellular therapy with DCs, and in particular underlie a previously unsuspected potential for specific treatment of diseases such as autoimmune diabetes and pancreatic cancer.

Project description:Purpose:The purpose of this study is to detect activated or silenced genes during LPS-induced dendritic cell maturation. Gene expression differences between two samples could be found using transcriptome profiling (RNA-seq) analysis. Methods:Mouse dendritic cells were generated from bone marrow cells in RPMI-1640 medium with recombinant mouse GM-CSF and IL-4, mature DCs were obtained after LPS induced maturation. Immature DCs and mature DCs were sorted respectively based on maturation marker CD86 and Iab(MHCII) using flowcytrometer. DC mRNA profiles were generated by deep sequencing,using Illumina Results: We mapped about 10 million sequence reads per sample to the mouse genome, identified 1,300 upregulated genes and 1,475 dow regulated genes during dendritic cell maturation.

Project description:Following UV irradiation of skin, dendritic cells (DCs) differentiating from the bone marrow (BM) of mice have a reduced ability to prime new immune responses; their reduced immunogenicity is maintained for at least 16 weeks in UV-chimeric mice. We hypothesized that different metabolic states underpin changes in DC function. Compared with DCs from the BM of non-irradiated mice, DCs from the BM of UV-irradiated mice produced more lactate and utilized greater amounts of glucose, a profile that was supported by greater glycolytic flux when incubated in low-serum-containing medium. Responses to a mitochondrial stress test were similar suggesting that the DCs from the BM of UV-irradiated mice had not switched from a profile of oxidative phosphorylation, but were imprinted for greater glycolytic responses. After microarray profiling, RT-qPCR confirmation and Ingenuity pathway analysis, greater expression of the enzyme, 3-hydroxyanthranilate 3,4-dioxygenase, was identified as a potential contributor to increased glycolysis by BM-differentiated DCs. This enzyme provides the final step of the biosynthetic pathway from tryptophan to quinolinate, the universal de novo precursor to the pyridine ring of nicotinamide adenine dinucleotide (NAD), and may provide a mechanism to ensure sufficient NAD is available to support enhanced glycolysis. Increased lactate production was also measured for DCs from the BM of 16-week engrafted UV-chimeric mice and suggests long-lasting imprinting of progenitor cells for altered immunometabolism in their progeny cells. This study provides evidence of changes to metabolic states that associate with altered DC function.

Project description:Background : Poxviruses have been shown to be efficient vectors for the production of protective immune responses in host species but also in on host species. Myxoma virus belongs to poxviridae family. In order to evaluate the capacity of (MYXV) as a vaccine vector in ruminants, we invistigated its interactions with bone marrow-derived dendritic cells (BM-DC). DCs are the most potent antigen-presenting cells and play a crucial role during the priming and reactivation of antigen-specific immune responses . Following infection by a pathogen, the functional changes of DC are essential since priming and polarization of the immune response depend on these changes . Therefore a better understanding of the modifications in gene expression of proinflammatory cytokines, chemokines and stimulatory molecules expression may prove useful in predicting whether or not a vaccine vector will be effective. Moreover, it may help identifying modifications for improving its efficacy. Methodology/Principal Findings: We investigated in vitro the interactions between recombinant MYXV expressing GFP protein, SG33-GFP and ovine BM-DCs. To gain a global view of the gene remodelling induced by MYXV, we infected BM-DCs from three sheep with SG33-GFP at different multiplicity of infection (MOI) (0, 1, 3) during different time (0, 3, 8 hours). We measured the expression of 15K probes in BM-DCs after each kind of conditions with ovine Agilent microarrays. Furthermore, a selected number of genes were confirmed by RT-qPCR. MYXV infection induces a strong reprogramming of the cells leading to the expression of pro-inflammatory cytokines and mobilisation of type I IFN pathways, cellular death and features associated with the activation of the adaptive immune response. Conclusion/Significance: Microarray profiling of a poxvirus-DC interaction help to delineate some interesting features of a vector candidate in ovine, and pave the way for additional improvements of a promising platform.

Project description:Sepsis is associated with profound immune dysregulation that increases the risk for life-threatening secondary infections: Dendritic cells (DCs) undergo functional reprogramming due to yet unknown changes during differentiation in the bone marrow (BM). We investigated whether T cells alter the gene expression in the bone marrow during sepsis using microarrays.
