Project description:The precise molecular mechanisms controlling tissue resident T cell (Trm cell) development remain unclear. In our studies, we have found that the vitamin A metabolite all-trans retinoic acid (atRA) synergises with TGFβ to promote Trm cells. We further show that polyclonal activation of naive splenic CD8 T cells in the presense of IL-2, IL-15, TGFβ + atRA leads to the development of CD69+CD103+ Trm cells. We have examined the transcriptome of CD8 T cells under IL-2/15, IL-2/15/atRA, IL-2/IL-15/TGFβ and IL-2/IL-15/TGFβ/atRA conditions.

Project description:The specifying signals provided by the tissue microenvironment to promote acquisition of Trm features vary across anatomical niches, and those delivered in the large intestine (LI) remain largely uncharacterized. Here we show that following migration of activated T cells from the priming lymph nodes, antigen recognition in the tissue microenvironment is crucial to establish LI CD8 Trm. In the absence of tissue-confined antigen, T cells fail to generate memory precursors and to accumulate in the tissue. Local antigen presentation boosts Trm generation in a dose-dependent manner, and prompts transient acquisition of a distinctive transcriptional program including key signatures of gut Trm. The definitive transcriptional landscape of LI Trm cells comprises both features that are shared with Trm at other locations, as well as unique elements. Our findings identify antigen presentation in the gut microenvironment as a key step in the generation of large LI CD8 Trm, providing key insight for the optimization of mucosal immunization strategies.

Project description:Ageing can compromise antitumor immunity, but the underlying mechanism by which ageing causes CD8+ T cell dysfunction and thus limits their antitumor activity remains poorly understood. We found that ageing greatly impaired the generation of CD8+ tissue-resident memory T (TRM) cell subset in non-lymphoid tissues (NLTs). And here we presented that in vitro differentiation of TRM cells was inhibited in the aged CD8+ T cell group compared to the young CD8+ T cell group.

Project description:Purpose: To characterize the tumor-specific TRM cells in LNs, skin, lung and liver in mice with melanoma-associated vitiligo (MAV). Bulk RNA-seq was performed to identify populations of CD8 T cells with TRM transcriptional characteristics. Methods: CD8+THy1.1+ T cells were sorted from DLN, skin lung and liver of MAV mice and bulk RNA-sequenced Results: Heterogenouse CD8 memory populations with both circulatating and resident phenotypes were identified. Conclusions: Tumor-specific CD8 T cells form TRM responses in tumor-draining LNs.

Project description:The aim of the experiment was to understand the clonal relationship between CD8+ central memory blood T cells (TCM) and the in-vivo matured TCM tissue-resident memory-like T cells (TRM) on day 14. TCM were FACS sorted from human PBMCs (n=5). Half of the cells were processed on day 1 and half of the cells of each donor were matured into TRM with anti-CD3, IL-15 and TGF beta for 14 days. Both day 1 TCM and matured day 14 TRM-like cells were further processed using the 5´10X genomics workflow.

Project description:This study seeks a better understanding of the functional differences between naturally acquired murine CD8+ T resident memory (Trm) cells of three distinct mucosal environments; the small intestine, the lung and the liver. CD8+ Trm cells of healthy young adult mice were retrieved from their respective organ environments by automated organ disintegration and MACS sorting, and compared with each other by whole genome gene expression profiling. Peripheral blood derived circulating CD8+ Tem cells were also analyzed, serving as nonresident peripheral memory T cell controls, in an attempt to identify common characteristics of resident mucosal CD8+ Trm subsets, as well.

Project description:CD8 Tissue Resident Memory (TRM) induction
| PRJNA1036221 | ENA
Project description:Tissue resident memory (Trm) represent a newly described memory T cell population. We have previously characterized a population of Trm that persists within the brain following acute virus infection. Although capable of providing marked protection against a subsequent local challenge, brain Trm do not undergo recall expansion following dissociation from the tissue. Furthermore, these Trm do not depend on the same survival factors as the circulating memory T cell pool as assessed either in vivo or in vitro. To gain greater insight into this population of cells we compared the gene-expression profiles of Trm isolated from the brain to circulating memory T cells isolated from the spleen following an acute virus infection. Trm displayed altered expression of genes involved in chemotaxis, expressed a distinct set of transcription factors and overexpressed several inhibitory receptors. Cumulatively, these data indicates that Trm are a distinct memory T cell population disconnected from the circulating memory T cell pool and displaying a unique molecular signature which likely results in optimal survival and function within their local environment. 13 samples were analyzed: 5 replicates of memory OT-I CD8+.CD103- T cells isolated from the spleen of mice on day 20 p.i. with VSV-OVA. 5 replicates of memory OT-I CD8+CD103+ T cells isolated from the brain of mice on day 20 p.i. with VSV-OVA; and 3 replicates of memory OT-I.CD8+ CD103- T cells isolated from the brain of mice on day 20 p.i. with VSV-OVA

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.
