Co-expression of CD163 and CD141 Identifies Human Circulating IL-10-Producing Dendritic Cells (DC-10) [expression array]

Project description:Tolerogenic dendritic cells (DC) are key players in maintaining immunological homeostasis, dampening immune reactions, and promoting tolerance. DC-10, a tolerogenic population of human IL-10-producing DC characterized by the expression of HLA-G and ILT4, play a pivotal role in promoting tolerance via T regulatory type 1 (Tr1) cells. Thus far, the absence of specific biomarkers that uniquely identify DC-10 limited their studies in vivo. By gene expression profiling of in vitro differentiated human DC, we identified CD141 and CD163 as specific surface markers for DC-10. The co-expression of CD141 and CD163 in combination with CD14 and CD16 enables the ex vivo isolation of blood circulating DC-10. FACS-isolated CD14+CD16+CD141+CD163+ cells (ex vivo DC-10) from peripheral blood of healthy subjects produced spontaneously and upon activation IL-10 and limited levels of IL-12. Moreover, in vitro stimulation of allogeneic naive CD4+ T cells with ex vivo isolated CD14+CD16+CD141+CD163+ cells induced the differentiation of allo-specific Tr1 cells. Finally, ex vivo isolated CD14+CD16+CD141+CD163+ cells and in vitro differentiated DC-10 exhibited a similar transcriptional profile, characterized by anti-inflammatory and pro-tolerogenic signature. These results provide new insight into the DC-10 phenotype and on the role of circulating DC-10 in modulating T cell responses and promoting Tr1 cells. These findings open the opportunity to track DC-10 in vivo and to define their role in physiological and pathological settings.

Coexpression of CD163 and CD141 identifies human circulating IL-10-producing dendritic cells (DC-10).

Moreover, in vitro stimulation of allogeneic naive CD4+ T cells with ex vivo DC-10 induced the differentiation of alloantigen-specific CD49b+LAG-3+ Tr1 cells. Finally, ex vivo DC-10 and in vitro generated DC-10 exhibited a similar transcriptional profile, which are characterized by an anti-inflammatory and pro-tolerogenic signature. These results provide new insights into the phenotype and molecular signature of DC-10 and highlight the tolerogenic properties of circulating DC-10. These findings open the opportunity to track DC-10 in vivo and to define their role in physiological and pathological settings.

Function of human CD141+ DC and CD1c+ DC in a humanized mouse model in vivo

Project description:Human immune cell subsets develop in immunodeficient mice following reconstitution with human CD34+ haematopoietic stem cells. These “humanized” mice are useful models to study human immunology and human-tropic infections, autoimmunity and cancer. However, some human immune cell subsets are unable to fully develop or acquire full functional capacity due to a lack of cross-reactivity of many growth factors and cytokines between species. “Classical” (c) DC arise from a separate precursor to monocytes and initiate and direct T cell responses. In mice they can be further categorized into cDC1, which mediate Th1 and CD8+ T cell responses, and cDC2, which mediate Th2 and Th17 responses. The gene expression profiles and phenotype human CD141+ DC and CD1c+ DC subsets align with mouse cDC1 and cDC2 respectively but there are also key interspecies differences. Human CD141+ DC and CD1c+ DC develop in humanized mice but the extent to which they resemble their human blood counterparts is not yet known. We therefore analyzed the gene expression profiles of CD141+ DC and CD1c+ DC in humanized mice and demonstrated that they closely resemble those in human blood, making this an attractive model in which to study human DC in vitro or on vivo. We further used this model to explore changes in DC subsets after activation with TLR3 and TLR7/8 ligands, poly I:C and R848 in vivo. A core panel of genes consistent with DC maturation status were upregulated by both subsets. R848 specifically upregulated genes associated with Th17 responses by CD1c+ DC, whilst poly I:C upregulated IFN-λ genes specifically by CD141+ DC. Thus CD141+ DC and CD1c+ DC share a similar activation profiles in vivo but also have induce unique signatures that support specialized roles in CD8+ T cell priming and Th17 responses respectively.

Gene expression profiling dendritic cells (DC) producing IL-10

Project description:To identify factors associated with the immunosuppressor activity of IL-10+ DC, these cells were obtained from VertX mice immunized with OVA+imiquimod and compared with IL-10- DCs from the same mice and from VertX mice, either untreated or vaccinated with OVA+poly(I:C).

Human Skin CD141+ Dendritic Cells Regulate Cutaneous Immunity via the Neuropeptide Urocortin-2

Project description:Skin immune homeostasis is a multi-faceted process where dermal dendritic cells (DDCs) are key in orchestrating responses to environmental stressors. We have previously identified CD141+CD14+DDCs as a skin-resident immunoregulatory population that is vitamin-D3(VitD3) inducible from monocyte-derived DCs(moDCs), termed CD141hiVitD3 moDCs. We demonstrate CD141+DDCs and CD141hiVitD3 moDCs share key immunological features including cell surface markers, reduced T-cell stimulation, IL-10 production, and a common transcriptomic signature. Bioinformatic analysis identified the neuroactive ligand receptor pathway and the neuropeptide, urocortin-2(UCN2), as a potential immunoregulatory candidate molecule. Incubation with VitD3 up-regulated UCN2 in CD141+DCs and ultraviolet-B(UVB) irradiation induced UCN2 in CD141+DCs in healthy skin in vivo. Notably, CD141+DDC generation of suppressive Tregs was dependent upon the UCN2 pathway as in vivo administration of UCN2 reversed skin inflammation in humanized mice. We propose the neuropeptide UCN2 as a novel skin DC- derived immunoregulatory mediator with a potential role in UVB and VitD3 dependent skin immune homeostasis.
