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.

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.

Intestinal CD103- Trm cells are first responders to secondary infection

Project description:To address both the plasticity of intestinal Trm subsets and their unique contributions to tissue and systemic immunity, we have generated mice to fate map CD103+ Trm cells after primary infection and follow their location and functionality during secondary infection. We found that the intestinal CD103– Trm subset are the primary responders to secondary infection and observed limited expansion of the CD103+ Trm subset. To understand the unique features of CD103– Trm cells that allow this population to respond more quickly to secondary infection and to understand the gene expression changes that accompany Trm reactivation, we performed RNA-sequencing on CD103+Tomato+ and CD103–Tomato– LP Trm cells.

Transcription profiling by array of excisional biopsy wounds from young and old human subjects to measure the influence of age on cutaneous wound healing

Project description:The aim of this experiment was measure the influence of age on cutaneous wound healing using human subjects. Increaded age has been associated with delayed wound healing in mouse models and in humans. Gene expression was compared between excisional biopsy wounds from young and old subjects.

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.

RNA-seq transcriptome analysis of epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- T cells from healthy human skin

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.
