Bulk RNAseq of Sort-purified IV- Primary (1M) or Quaternary (4M) Tcirc (IV- CD69-/CD103-) or Trm (IV- CD69+/CD103+) Memory P14 cells isolated from Spleen or Mediastinal Lymph Nodes

Project description:Purpose: The goals of this study are to compare the phenotypic, transcriptomic, trafficking and functional atttibutes of Influenza-experienced circulating or resident memory phenotype cells from the spleen or lung-draining mediastinal lymph nodes. Results: Following read alignment, gene expression profiles were computed using featureCounts. Filtering and visualization of differentially expressed genes with a log2fold change >1.5<-1.5 and a p value of less than 0.05 were identified using Partek GS software and for some figures values from Partek were normalized and displayed using GraphPad Prism. Gene set enrichment and functional assignment were performed in DAVID bioinformatics resources and software from the Broad Institute.

Human CD4+CD103+ cutaneous resident memory T cells are found in the circulation of healthy subjects

Project description:Tissue-resident memory T cells (TRM) persist locally in non-lymphoid tissues where they provide front-line defense against recurring insults. TRM at barrier surfaces express the markers CD103 and/or CD69 which function to retain them in epithelial tissues. In humans, neither the long-term migratory behavior of TRM nor their ability to re-enter the circulation and potentially migrate to distant tissue sites have been investigated. Using tissue explant cultures, we found that CD4+CD69+CD103+ TRM in human skin can downregulate CD69 and exit the tissue. Additionally, we identified a skin-tropic CD4+CD69-CD103+ population in human lymph and blood that is transcriptionally, functionally and clonally related to the CD4+CD69+CD103+ TRM population in the skin. Using a skin xenograft model, we confirmed that a fraction of the human cutaneous CD4+CD103+ TRM population can re-enter circulation, and migrate to secondary human skin sites where they re-assume a TRM phenotype. Thus, our data challenge current concepts regarding the strict tissue compartmentalization of CD4+ T cell memory in humans.

Differential gene expression of tissue-resident memory and effector memory T cells in breast cancer

Project description:Two infiltrating T cell populations (CD8+CD69+CD103+ and CD8+CD69+CD103-) were isolated from 3 breast cancer tumors by FACS for gene expression profiliing.

Induced CD103+ Dendritic Cells

Project description:Multiple subsets of FLT3L-dependent dendritic cells (DCs) control T cell tolerance and immunity. In mouse tissues, CD8α-like DCs are identified by CD103 expression. This DC subset efficiently enters lymph nodes and cross-presents antigens, rendering CD103+ DCs promising targets for therapeutic tolerance induction or vaccination. However, only limited numbers of CD103+ DCs can be isolated with current methods. Moreover, bone marrow cultures with FLT3L produce complex mixtures of DC subsets. We developed a novel method for generating large numbers of Batf3-dependent CD103+ DCs. We used microarray analysis to compare in vitro generated CD103+ and CD103- DCs and correlated their expression patterns to published profiles and signatures of DC subsets.

Whole-transcriptome profiling of murine steady state CD69+ and CD69- memory CD8+ T cells from the bone marrow [expression microarray]

Project description:To understand the tissue-resident features of memory CD8+ T cell subpopulations isolated from the bone marrow according to the tissue retention marker CD69, we compared the global gene expression of ex vivo isolated CD69+ and CD69- bone marrow memory CD8+ T cells.

RNA sequencing of NK cells in human lung

Project description:Human lung tissue-resident NK cells (trNK cells) are likely to play important roles in viral infections, inflammation and cancer. However, knowledge about lung trNK cells is lacking but is fundamental for exploiting these cells in therapeutic approaches. Here we analysed the transcriptome of CD69+CD49a+CD103+CD16-CD56bright, CD69+CD49a+CD103-CD16-CD56bright, CD69+CD49a-CD103-CD16-CD56bright, CD69-CD49a-CD103-CD16-CD56bright, and CD56dimCD16+NKG2A+CD57- NK cells isolated from human lung.

Transcription profile of CD103- vs CD103+ dendritic cells derived from CX3CR1+c-kit+- bone marrow cells (M1993 M2067)

Project description:We hypothesize that under homeostatic as well as inflammatory conditions circulating monocytes and/or their bone marrow-derived progenitors might contribute to the replenishment of CD103+ and CD103- DC in lymphoid and non-lymphoid compartments. To that end, bone marrow cells from CX3CR1+/gfp C57BL/6 mice were sorted as follows: lineage negative (CD3, CD19, NK1.1, Ter119, Ly6G and CD11c) CX3CR1+c-kit+. Sorted cells were further cultured in vitro under the continuous presence of GM-CSF. lin-CX3CR1+c-kit+ bone marrow cells gave rise to CD103+ and CD103- DC in vitro. To test whether CD103 might be a suitable marker that allows the differentiation of functionally distinct DC subsets generated in vitro, CD11c+CD103+ and CD11c+CD103- DC were sorted from day 5 cultures of lin-CX3CR1+c-kit+ cells and analyzed by whole mouse genome microarrays from Agilent technologies. Compared to CD103+ DC, CD103- DC displayed a strong up-regulation of transcripts for genes involved in innate immunity, whereas those involved in costimulation were down-modulated. Our data suggest distinct functional activity of these two DC subsets. Keywords: Transcriptional profiling-Cell type comparison We compared the transcriptional profile of CD11c+CD103+ and CD11c+CD103- dendritic cells by use of Agilent Whole Mouse Genome Microarrays. Two sets of samples were generated independently as real biological replicates. The microarray analysis was performed as a dual-color experiment, including a dye-swap.
