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:Human dendritic cells (DCs) 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 exposure is thus essential to determine the nature and magnitude of maturation signals that have been shown to strongly correlate with vaccine effectiveness. In 2009, the H1N1 influenza epidemics fostered the commercialization of the nonadjuvanted monovalent H1N1 California vaccine (MIV-09) to complement the existing nonadjuvanted trivalent Fluzone 2009-2010 vaccine (TIV-09). In retrospective studies, MIV-09 displayed lower effectiveness than TIV-09. We show that TIV-09 induces monocyte-derived DCs (moDCs), 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 (IFNs) IFN-α and IFN-β and type III IFN interleukin-29 (IL-29) by moDC and cDC subsets. The vaccine also induced the production of IL-6, tumor necrosis factor, and the chemokines IFN-γ-inducible protein 10 (IP-10) and macrophage inflammatory protein-1β (MIP-1β). Conversely, MIV-09 did not induce the production of type I IFNs in moDCs and blood cDCs. Furthermore, it inhibited the TIV-09-induced secretion of type I IFNs by these DCs. However, both vaccines induced pDCs to secrete type I IFNs, indicating that different influenza vaccines activate distinct molecular signaling pathways in DC subsets. These results suggest that subtypes of nonadjuvanted influenza vaccines trigger immunity through different mechanisms and that the ability of a vaccine to induce an IFN response in DCs may offset the absence of adjuvant and increase vaccine efficacy.

Project description:We exploited label-free quantitative mass spectrometry to compare primary human blood Dendritic cells (DCs) subsets protein expression to identify new markers. Subsets distinguished are: Plasmacytoid DCs (pDC) and BDCA3+ and CD1c+ myeloid DCs and CD16+ monocytes. The dendritic cells were analyzed by LC-MS/MS and processed by MaxQuant for identification and LFQ quantification.

Project description:Dendritic cell (DC) are critical initiators and regulators of immunity to pathogens, vaccines, tumors and tolerance to self. Mouse and human dendritic cells (DCs) are comprised of functionally specialized subsets, but precise interspecies correlation is currently incomplete and hampers the full translation of murine findings to human DC-based clinical therapies. In this study, we show that murine lung and gut lamina propria CD11b+ DC populations are comprised of two subsets: FLT3- and IRF4-dependent CD24+CD64- DCs and contaminating CSF-1R-dependent CD24-CD64+ macrophages. CD11b+CD24+CD64- DCs are instrumental in inducing Th17 cell immune response in the steady state and upon Aspergillus fumigatus challenge. We also identified human CD1c+CD11b+ DCs as the functional homologue of mouse mucosal CD11b+ DCs. Our findings highlight the conservation of key immune functions across species and aid the translation of murine studies to human DC immunobiology. The data for the associated human studies have been stored within GSE35459. Gene Expression from total RNA from specific mouse dendritic cell subsets purified by FACS

Project description:Dendritic cells (DCs) are critical in mediating immunity to pathogens, vaccines, tumors and tolerance to self. Significant progress has been made in the study of DC subsets in murine models but the translation of these findings to human DC immunobiology has not been fully realized. Murine splenic CD8+ DC and CD103+ DC possess potent antigen cross-presenting capacity. Although recent evidence points to human blood CD141+ DCs as the functional equivalent of CD8+ DC, the precise identity of the human migratory cross-presenting DC has remained elusive. We performed phenotypic and functional analyses to interrogate the DC compartment of human non-lymphoid tissues and identified three distinct subsets: i) CD141high DCs, ii) CD1c DCs and iii) CD14+ DCs. Only CD141high DCs were capable of cross-presenting soluble antigen. Comparative transcriptome analysis of steady state monocyte and DC subsets between mouse and human confirmed conservation between species, aligning the following subsets together: i) human CD141high DCs with mouse CD8+ and CD103+ DCs, ii) human CD1c+ DCs with mouse CD4+ DCs and iii) human CD14+ DC with mouse monocyte subsets. The lack of positive association between human CD1c+ DCs and mouse non-lymphoid tissue CD11b+ DCs highlights heterogeneity and predicts the existence of a monocyte-like cell within the CD11b+ DCs.
