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: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. 64 samples of IL4 DC, and 64 samples of monocytes stimulated by media (controls, designated 1 and 2 to indicate biological replicates), Menomune (Neisseiria meningitis vaccine, MGL), Fluzone 09-10 (Influenza vaccine, FZ), Havrix (Hepatitis A vaccine, HEPA), Ixiaro (Japanese encephalitis vaccine, JPE), ActHib (Haemophilus influenza vaccine, HIB) and Pneumovax (Pneumococcus vaccine, PVX), Engerix-B (Hepatitis B vaccine, HEPB), Zostavax (Herpes Zoster vaccine, HER), and Gardasil (Human Papilloma virus vaccine, HPV), LPS, Ipol (Polio vaccine, POL), Rabies vaccine (RAB), toxoid-based vaccine (TDAP), Varivax (Varicella vaccine, VAR)

Project description:Human dendritic cells play a fundamental role in the initiation of long-term adaptive immunity during vaccination against influenza. Understanding the early response of human DCs to vaccine challenge is thus essential to determine the nature and magnitude of maturation signals that strongly correlate with vaccine effectiveness. Here, we show that the non-adjuvanted trivalent Fluzone®09-10 (TIV-09) induces monocyte-derived DCs (moDCs), purified blood conventional DCs (cDCs) and plasmacytoid DCs (pDCs) to express CD80, CD83, and CD86, and secrete cytokines. TIV-09 stimulated the secretion of type I interferons (IFN) IFN-α and IFN-β and type III IFN IL-29 by moDCs and cDCs subsets. The vaccine also induced the production of IL-6, TNF and the chemokines IP-10 and MIP-1β. Conversely, the non-adjuvanted monovalent H1N1 California vaccine (MIV-09), which was commercialized in 2009 during the H1N1 epidemics and displayed lower effectiveness in retrospective studies, did not induce the production of type I IFN in moDCs and blood cDCs. Furthermore, it inhibited the TIV-09-induced secretion of type I IFN by these DCs. Yet, both vaccines induced pDCs to secrete type I IFN indicating that different influenza vaccines activate different molecular signaling pathways in different DC subsets. In vivo, the baseline IFN signature was decreased upon administration of the H1N1 vaccine in 3/3 pediatric lupus patients. These results suggest that subtypes of non-adjuvanted influenza vaccines elicit long-term protection through different mechanisms and that a vaccine’s ability to induce an IFN response in DCs may palliate the absence of adjuvant and increase vaccine efficacy.

Project description:Dendritic cell (DC) vaccine was among the first FDA-approved cancer immunotherapies, but has been limited by the modest cytotoxic T lymphocyte (CTL) response and therapeutic efficacy. Here we report a facile metabolic labeling approach that enables targeted modulation of adoptively transferred DCs for developing enhanced DC vaccines. We show that metabolic glycan labeling can reduce the membrane mobility of DCs, which activates DCs and improves the antigen presentation and subsequent T cell priming property of DCs. Metabolic glycan labeling itself can enhance the antitumor efficacy of DC vaccines. In addition, the cell-surface chemical tags (e.g., azido groups) introduced via metabolic glycan labeling also enable in vivo conjugation of cytokines onto adoptively transferred DCs, which further enhances CTL response and antitumor efficacy. Our DC labeling and targeting technology provides a new strategy to improve the therapeutic efficacy of DC vaccines, with minimal interference upon the clinical manufacturing process.
