Project description:We report the transcriptome analysis of epidermal CD8 tissue resident memory T (TRM) cells from healthy human skin. Specifically, epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM cells from healthy human skin were sorted by FACS. Differential gene expression analysis revealed functional dichotomy of epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM 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.

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.

Project description:Initially identified as a functional marker for resident-memory (Trm) CD8+ T cells, CD103 (encoded by ITGAE gene) has broad roles in immunity and diseases. Elucidating the function and regulation of CD103 is thus of importance. This study revealed that the CD103 expression by CD8 T cells under steady state contributes to the clearance of acute viral infection. More importantly, it discovered TGF-SKI-Smad4 a critical signaling axis in restricting CD103 expression in CD8+ T cells for their function. Mechanistically, by ChIP-Seq and ChIP analysis, SKI associated with Smad4 was found to directly and epigenetically suppress CD103 transcription. This study therefore reveals a novel TGF-SKI-Smad4 pathway to specifically enable CD103 expression in CD8+ T cells for protective immunity.

Project description:Tissue resident memory T cells (TRM) provide superior protection against infection localised to extra-lymphoid compartments in the body. Here we show that CD103+CD8+ TRM cells develop in skin from killer cell lectin-like receptor (KLR)G1-negative precursors that selectively infiltrate the epithelial layer. In the skin, a combination of chemokine-guided epithelial entry, local interleukin (IL)-15 and transforming growth factor (TGF)-β signalling is required for formation and survival of these long-lived memory cells. Importantly, TRM differentiation results in the gradual acquisition of a unique transcriptional profile that differs from that expressed by memory cells in the circulation and other types of skin-resident intra-epithelial T cells, such as the dendritic epidermal T cells (DETC). We provide a comprehensive molecular and developmental framework for the local differentiation of a distinct type of peripheral memory T cell that contributes to an important first-line of immune defence in barrier tissues such as skin and mucosa. 24 samples were analyzed: 3 replicates of memory gB-T CD8+. CD103+ T cells isolated from the skin of C57/BL6 mice on day 30 p.i. with HSV KOS. 3 replicates of memory P14 CD8+ T cells isolated from gut of mice on day 60 p.i. with LCMV Armstrong. 3 replicates of memory gB-T CD8+ T cells from the lung of mice on day 30 p.i. with influenza WSN. 3 replicates of memory CD62L high CD8+ T cells from the spleen of mice on day 30 p.i. with HSV KOS. 3 replicates of memory CD62L low CD8+ T cells from the spleen of mice of day 30 p.i. with HSV KOS. 3 replicates of γδ-DETC isolated from the skin of C57/BL6 mice on day 30 p.i. with HSV KOS. 3 replicates of αβ-DETC from naive TCRδ-/- mice; and 3 replicates of naive gB-T CD8+ T cells from the spleen of naive gB-T transgenic mice.

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

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.
