Project description:While dendritic cells (DCs) are known to play a major role in the process of vaccination, the mechanisms by which vaccines induce protective immunity in humans remain elusive. Herein, we used gene microarrays to characterize the transcriptional programs induced over time in human monocyte-derived DCs (moDCs) in vitro in response to influenza H1N1 Brisbane, Salmonella enterica and Staphylococcus aureus. We built a data-driven modular analytical framework focused on 204 pathogen-induced gene clusters. The expression of these modules was analyzed in response to 16 well-defined ligands, targeting TLRs, cytoplasmic PAMP receptors and cytokine receptors. This multi-dimensional framework covers the major biological functions of APC, including the IFN response, inflammation, DC maturation, T cell activation, antigen processing, cell motility and histone regulation. This framework was used to characterize the response of monocytes and moDCs to 14 commercially available vaccines. These vaccines displayed quantitatively and qualitatively distinct modular signatures in monocytes and DCs, in particular Fluzone and Pneumovax, highlighting the functional and phenotypic differences between APC subsets. This modular framework allows the application of systems immunology approaches to study early transcriptional changes in human APC subsets in response to pathogens and vaccines, which might guide the development of improved vaccines. 38 samples of IFNa DC and 39 samples of IL4 DC stimulated by CL097, CpG 2006, CpG 2216, Flagellin, IFNa, IL10, IL15, IL1b, LPS, MDP, PAM3, Poly I:C, Poly I:C-LMW-Lyovec, R837 or TNFa

Project description:The mechanisms by which vaccines interact with human APCs remain elusive. We applied systems biology to define the transcriptional programs induced in human DCs by pathogens, innate receptor ligands and vaccines. Upon exposing DCs to influenza, Salmonella enterica and Staphylococcus aureus, we built a modular framework containing 204 pathogen-induced transcript clusters. Module fingerprints were then analyzed in DCs activated with 16 innate receptor ligands. This framework was then used to characterize human monocytes, IL-4 DC and blood DC subsets responses to 13 vaccines. Different vaccines induced distinct signatures based on pathogen type, adjuvant formulation and APC targeted. Fluzone broadly activated IL-4 DC whereas pneumovax only activated monocytes and gardasil (HPV) only activated CD1c+ mDC. This highlights that different antigen-presenting cells respond to different vaccines. Finally, the blood signatures from individuals vaccinated with fluzone or infected with influenza were interpreted using these modules. We identified a signature of adaptive immunity activation following vaccination and symptomatic infections, but not asymptomatic infections. These data, offered with a web interface, might guide the development of improved vaccines. 5 donors; 88 samples; duplicate technical replicates for the medium control for each donor for the BDCA1+ mDC population; single medium control for each donor for the BDCA3+ mDC population (15 total medium controls).

Project description:Monocytes cultured in media containing GM-CSF and IL4 for 5 days normally differentiate into immature dendritic cells which, upon further stimulation with LPS for an additional 2 days, acquire a mature phenotype. In the present study, we evaluated the effect of human cord-blood mesenchymal stem cells (MSC) on human monocyte differentiation into immature and mature DCs by examining the trancriptional profile of the cells that were obtained after both the differentiation and maturation stages.

Project description:Variation in individuals' responses to environmental factors is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We measured gene expression from resting and stimulated dendritic cells (DCs) derived from the peripheral blood of healthy individuals. We stimulated the primary DCs with E. coli lipopolysaccharide (LPS), influenza virus or the cytokine IFNβ, and associated genetic variation between individuals with the observed variation in gene expression and gene induction. We collected peripheral blood from each human donor. We isolated peripheral blood mononuclear cells by Ficoll, and magnetically sorted them for CD14+CD16- monocytes. We then differentiated the monocytes into monocyte-derived dendritic cells (MoDCs) by culturing the cells for 7 days with GM-CSF and IL-4. We stimulated the cells with E. coli lipopolysaccharide (LPS) for 2.5 hr or 5 hr, influenza (PR8 dNS1) for 10 hr, or recombinant IFN-beta for 6.5 hr. Finally, we lysed the cells and ran Nanostring on the lysates.

The genetic basis of such variation is poorly understood. We measured gene expression from resting and stimulated dendritic cells (DCs) derived from the peripheral blood of healthy individuals. We stimulated the primary DCs with E. coli lipopolysaccharide (LPS) or influenza virus. Using serial replicate samples, we selected genes that showed evidence of reproducibility within the serial replicates. We collected peripheral blood from each human donor. We isolated peripheral blood mononuclear cells by Ficoll, and magnetically sorted them for CD14+CD16- monocytes. We then differentiated the monocytes into monocyte-derived dendritic cells (MoDCs) by culturing the cells for 7 days with GM-CSF and IL-4. We stimulated the cells with E. coli lipopolysaccharide (LPS) for 5 hr or influenza (PR8 dNS1) for 10 hr. Finally, we lysed the cells and isolated total RNA for microarray.

Project description:Excessive inflammation within the central nervous system is injurious, but an immune response is also required for its repair. Macrophages are versatile cells that adopt different properties depending upon their microenvironment. Exposing macrophages to interleukin-4 and -13 (IL4/IL13) has incurred interest for their reparative properties. Unexpectedly, while macrophages exposed to the classic pro-inflammatory signals (interferon-γ/lipopolysaccharide, IFN/LPS) killed neurons and oligodendrocytes in culture, the addition of LPS to IL4/IL13-treated macrophages profoundly elevated IL10, repair metabolites (lactate, ornithine), glucose metabolism and the oligodendrocyte-trophic heparin-binding epidermal growth factor (HBEGF); cells did not display pro-inflammatory or neurotoxic features. In mice with spinal cord demyelination, locally-applied IL4/IL13 was insufficient to alter responses beyond controls; remarkably, the LPS/IL4/IL13-treated animals significantly increased lesional phagocytic macrophages/microglia, lactate and HBEGF levels, oligodendrogenesis and remyelination. We report a remarkably reparative state of macrophages that is unexpectedly generated by the integration of pro- (LPS) and anti- (IL4/IL13) inflammatory activation cues.
