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.

Project description:Dendritic cells (DC) develop from hematopoietic stem cells, which is guided by instructive signals through cytokines. DC development progresses from multipotent progenitors (MPP) via common DC progenitors (CDP) into DC. Flt3 ligand (Flt3L) signaling via the Flt3/Stat3 pathway is of pivotal importance for DC development under steady state conditions. Additional factors produced during steady state or inflammation, such as TGF-beta1 or GM-CSF, also influence the differentiation potential of MPP and CDP. Here, we studied how gp130, GM-CSF and TGF-beta1 signaling influence DC lineage commitment from MPP to CDP and further into DC. We observed that activation of gp130 signaling promotes expansion of MPP. Additionally, gp130 signaling inhibited Flt3L-driven DC differentiation, but had little effect on GM-CSF-driven DC development. The inflammatory cytokine GM-CSF induces differentiation of MPP into inflammatory DC and blocks steady state DC development. Global transcriptome analysis revealed a GM-CSF-driven gene expression repertoire that primes MPP for differentiation into inflammatory DC. Finally, TGF-beta1 induces expression of DC-lineage affiliated genes in MPP, including Flt3, Irf-4 and Irf-8. Under inflammatory conditions, however, the effect of TGF- beta1 is altered: Flt3 is not upregulated, indicating that an inflammatory environment inhibits steady state DC development. Altogether, our data indicate that distinct cytokine signals produced during steady state or inflammation have a different outcome on DC lineage commitment and differentiation. 6 samples in total.

Project description:Dendritic cells (DCs) in lymphoid tissue comprise conventional DCs (cDCs) and plasmacytoid DCs (pDCs) that develop from common DC progenitors (CDPs). CDPs are Flt3+c-kitintM-CSFR+ and reside in bone marrow. Here we describe a two-step culture system that recapitulates DC development from c-kithiFlt3-/lo multipotent progenitors (MPPs) into CDPs and further into cDC and pDC subsets. MPPs and CDPs are amplified in vitro with Flt3 ligand, stem cell factor, hyper-IL-6 and insulin- like growth factor-1. The four-factor cocktail readily induces self-renewal of MPPs and their progression into CDPs and has no self-renewal activity on CDPs. The amplified CDPs respond to all known DC poietins and generate all lymphoid tissue DCs in vivo and in vitro. Additionally, in vitro CDPs recapitulate the cell surface marker and gene expression profile of in vivo CDPs and possess a DC-primed transcription profile. Transforming growth factor-β1 (TGF-β1) impacts on CDPs and directs their differentiation towards cDCs. Genome-wide gene expression profiling of TGF-β1-induced genes identified transcription factors, such as interferon regulatory factor-4 (IRF-4) and RelB, that are implicated as instructive factors for cDC subset specification. TGF-β1 also induced the transcription factor inhibitor of differentiation/DNA binding 2 (Id2) that suppresses pDC development. Thus, TGF-β1 directs CDP differentiation into cDC by inducing both cDC instructive factors and pDC inhibitory factors. 20 samples in total.

Project description:Dendritic cells (DC) are professional antigen presenting cells that comprise different subsets: classical DC type 1 and 2 (cDC1 and cDC2, respectively) and plasmacytoid DC (pDC). In this study cDC1 or pDC were obtained in a two-step in vitro culture system according to Felker et al., J. Immunol. 185, 5326-5335, 2010. Briefly, mouse bone marrow cells were first amplified with a specific cytokine cocktail and then induced to differentiate into DC with Flt3 ligand. cDC1 are CD11c+ CD11b+ XCR1+ and pDC are CD11c+ CD11b- B220+ and thus cDC1 and pDC were obtained by FACS sorting and subjected to Omin-ATAC-seq analysis. As an example of practical application of HINT-ATAC, we performed Omin-ATAC-seq experiments of cDC and pDC cell populations and used HINT-ATAC to detect footprints within ATAC-seq peaks of each of these two cells. Next, we estimated changes in binding activity for all factors with a motif in JASPAR. Cell-specific TF activity is measured by the depth of footprints and number of reads flanking regions. Two known cDC factors, BATF3 and HES1, are detected. In summary, we demonstrated that HINT-ATAC is capable of identifying relevant factors for dendritic cell specification.
