Transcriptional and functional analysis of CD1c+ human dendritic cells identifies a CD163+ subset priming CD8+CD103+ T cells [Breast_iLN]

Project description:Dendritic cells (DC) are antigen presenting cells controlling T cell activation. In human, the diversity, ontogeny and functional capabilities of DC subsets are not fully understood. Here, we identified circulating CD88-CD1c+CD163+ DC (termed as DC3) as an immediate precursor of inflammatory CD88-CD14+CD1c+CD163+FcεRI+ DC. DC3 develop via a specific pathway activated by GM-CSF, independent from the cDC-restricted (CDP) and monocyte-restricted (cMoP) progenitors. As classical DC, but unlike monocytes, DC3 drove the activation of naïve T cells. In vitro, DC3 displayed a distinctive ability to prime CD8+ T cells expressing a tissue-homing signature and the epithelial homing alpha-E integrin (CD103) through transforming growth factor-b (TGF-β) signaling. In vivo, DC3 infiltrated luminal breast cancer primary tumors and DC3 infiltration correlated positively with CD8+CD103+CD69+ tissue-resident memory T cells. Altogether, these findings define DC3 as a lineage of inflammatory DC endowed with a strong potential to regulate tumor immunity.

Human CD1c+ dendritic cells drive the differentiation of CD103+ CD8+ mucosal T cells via TGF-?

Project description:In comparison to murine dendritic cells (DCs), less is known about the function of human DCs in tissues. Here, we analyzed, using lung tissues from humans and humanized mice, the role of human CD1c+ and CD141+ DCs in determining the type of CD8+ T cell immunity to live-attenuated influenza virus (LAIV) vaccine. We found that both lung DC subsets acquired influenza antigens in vivo and expanded specific cytotoxic CD8+ T cells in vitro. However, lung-tissue-resident CD1c+ DCs but not CD141+ DCs were able to drive CD103 expression on CD8+ T cells and promote CD8+ T cell accumulation in lung epithelia in vitro and in vivo. CD1c+ DCs induction of CD103 expression was dependent on membrane-bound TGF-?1. Thus, CD1c+ and CD141+ DCs generate CD8+ T cells with different properties, and CD1c+ DCs specialize in the regulation of mucosal CD8+ T cells. Total RNA were isolated from purified human CD1c+ (BDCA1+) and CD141+ (BDCA3+) mDCs sorted from different tissues, including human blood, spleen and lungs of humanized mice, and human lungs. Eighteen samples in total were analyzed from different donors and tissues.

Retinoic acid signaling during priming licenses intestinal CD103+ CD8 TRM cell differentiation

Project description:CD8 tissue-resident memory T (TRM) cells provide front-line protection at barrier tissues; however, mechanisms regulating TRM cell development are not completely understood. Priming dictates the migration of effector T cells to the tissue, while factors in the tissue induce in situ TRM cell differentiation. Whether priming also regulates in situ TRM cell differentiation uncoupled from migration is unclear. Here, we demonstrate that T cell priming in the mesenteric lymph nodes (MLN) regulates CD103+ TRM cell differentiation in the intestine. In contrast, T cells primed in the spleen were impaired in the ability to differentiate into CD103+ TRM cells after entry into the intestine. MLN priming initiated a CD103+ TRM cell gene signature and licensed rapid CD103+ TRM cell differentiation in response to factors in the intestine. Licensing was regulated by retinoic acid signaling and primarily driven by factors other than CCR9 expression and CCR9-mediated gut homing. Thus, the MLN is specialized to promote intestinal CD103+ CD8 TRM cell development by licensing in situ differentiation.

Transcriptional and Functional Analysis of CD1c+ Human Dendritic Cells Identifies a CD163+ Subset Priming CD8+CD103+ T Cells.

Project description:Dendritic cells (DCs) are antigen-presenting cells controlling T cell activation. In humans, the diversity, ontogeny, and functional capabilities of DC subsets are not fully understood. Here, we identified circulating CD88-CD1c+CD163+ DCs (called DC3s) as immediate precursors of inflammatory CD88-CD14+CD1c+CD163+FcεRI+ DCs. DC3s develop via a specific pathway activated by GM-CSF, independent of cDC-restricted (CDP) and monocyte-restricted (cMoP) progenitors. Like classical DCs but unlike monocytes, DC3s drove activation of naive T cells. In vitro, DC3s displayed a distinctive ability to prime CD8+ T cells expressing a tissue homing signature and the epithelial homing alpha-E integrin (CD103) through transforming growth factor β (TGF-β) signaling. In vivo, DC3s infiltrated luminal breast cancer primary tumors, and DC3 infiltration correlated positively with CD8+CD103+CD69+ tissue-resident memory T cells. Together, these findings define DC3s as a lineage of inflammatory DCs endowed with a strong potential to regulate tumor immunity.

An unconventional integrin b3 and CD103 heterodimer improves the anti-tumor immunity of tissue-resident T cells

Project description:Current cancer immunotherapies promote recovery of CD103+ tissue-resident memory T cells (Trm) population of the tumor-infiltrating T lymphocytes (TILs). However, not all treated patients exhibit improved anti-tumor immunity and survival, likely due to the immunophenotypical diversity among the CD103+ Trm TILs. Utilising multifaceted proteomics approaches and patients’ clinical analyses, we discovered an unusual subset of CD8+ Trm TILs expressing non-canonical integrin β3 early during T cells activation. The integrin β3 surprisingly heterodimerises with CD103 on T cells, leading to unconventional granulysin-mediated cytotoxicity, elevated alternative bioenergy usage and efficient T cell migration, with minimal overall exhaustion. Importantly, early-stage non-small cell lung carcinoma (NSCLC) patients with enriched presence of integrin β3+CD103+ Trm TILs exhibited better clinical prognosis, with improved T cell immunophenotype, hence confirming the beneficial role of this unusual subset of Trm TILs. These unconventional anti-tumor T cell features provide new avenues and future opportunities for designing better translational immunotherapy strategies.

Cross-presenting CD103+ dendritic cells are protected from influenza virus infection

Project description:CD8+ cytotoxic T cells are critical for viral clearance from the lungs upon influenza virus infection. The contribution of cross-presentation to the induction of anti-viral cytotoxic T cells remains debated. Here, we used a recombinant influenza virus expressing a NS1-GFP reporter gene to visualize the route of antigen presentation by lung dendritic cells (DC) upon viral infection in vivo. We found that lung CD103+ DC are the only subset to carry intact GFP protein to the draining lymph nodes. Strikingly, lung migratory CD103+ DC are not productively infected by influenza virus and thus induce virus-specific CD8+ T cells through the cross-presentation of antigens from virally infected cells. We also show that CD103+ DC resistance to infection correlates with an increased antiviral state in these cells that is dependent on the expression of IFN receptor alpha. In conclusion, these results establish that efficient cross-priming by migratory lung DC is coupled to the acquisition of an anti-viral status, which is dependent on type I IFN signaling pathway. mRNA profiles were generated by deep-sequencing in Illumina HiSeq2000 from alveolar macrophages and CD103+ dendritic cells from lungs of untreated and flu-treated mice
