Project description:We used microarray to compare gene expression between CD161++/CD161+/CD161-CD8+ T cells from human cord blood. Lymphocytes from freshly obtained human cord blood samples were isolated by Ficoll density centrifugation. CD8+ T cells were purified by negative selection using magnetic beads and subsequently labelled with fluorescent antibodies prior to sorting using MoFlo MLS cell sorter (Dako).

Project description:T lymphocytes are conventionally divided into subsets based upon expression of co-receptors, cytokines and surface molecules. By mRNA microarray analysis, T lymphocytes that express the C-type lectin CD161 were identified to share a transcriptional profile, which led to the identification of an innate function across these previously defined subsets, including CD8, CD4 and TCRgd T cells. Gene expression of sort purified, resting CD161++, CD161+ and CD161- CD8+ T cells from peripheral blood was measured in 4 healthy donors.

Project description:We used microarrays to compare gene expression between healthy human CD161++CD8aa and CD161++CD8ab T cells. We sorted freshly obtained peripheral blood mononucleocytes from healthy controls by first using magnetic beads to negatively select for CD8a+ T cells, fluorescently labelling isolated cells with antibodies and subsequent sorting using MoFlow MLS cell sorter (DAKO). Sorted samples were snap frozen. RNA was later extracted from the sorted populations prior to hybridization to Affymetrix arrays.

Project description:We applied a cell population transcriptomics strategy to sorted human memory CD8 T cells to define novel immune signatures of latent tuberculosis infection (LTBI) and understand the phenotype of tuberculosis (TB)-specific T cells. We found a 41-gene signature that could discriminate between memory CD8 T cells from healthy LTBI subjects and noninfected controls. The gene signature was dominated by genes known to be associated with mucosal associated invariant T cells (MAITs) and reflected the lower frequency of MAITs observed in individuals with LTBI. There was no evidence for a conventional CD8 T cell specific signature between the two cohorts. We therefore investigated the MAITs in more detail in these cohorts. Phenotyping based on Vα7.2 and CD161 expression and MR1 tetramers revealed 2 distinct populations of CD8+Vα7.2+CD161+ T cells: MR1 tetramer+ and MR1 tetramer−, both of which had a distinct gene expression profile compared to CD8 memory T cells. Transcriptomic analysis of LTBI vs. noninfected individuals did not reveal significant differences for MR1 tetramer+ cells. However, gene expression of MR1 tetramer− cells showed a very different profile with large inter-individual diversity and a TB-specific signature. This was further strengthened by a more diverse TCR-α and -β repertoire of MR1 tetramer− cells as compared to MR1 tetramer+. Thus, cell population transcriptomics revealed a dominant MAIT signature in CD8 memory T cells that upon detailed investigation provided novel insights into the phenotype of different MAIT populations implicated in tuberculosis.

Project description:T lymphocytes are conventionally divided into subsets based upon expression of co-receptors, cytokines and surface molecules. By mRNA microarray analysis, T lymphocytes that express the C-type lectin CD161 were identified to share a transcriptional profile, which led to the identification of an innate function across these previously defined subsets, including CD8, CD4 and TCRgd T cells. Gene expression of magnetically enriched, resting CD161+ and CD161- CD4+ T cells from peripheral blood was measured in 3 healthy donors.

Project description:In comparison with allogeneic hematopoietic stem cell transplantation using other sources, umbilical cord blood transplantation (UCBT) offers substantial clinical advantages including a lower incidence and severity of acute graft-versus-host disease (GVHD) despite the use of allogeneic UCB stem cells with more disparate HLA. However, detailed pathophysiology of acute GVHD developed after UCBT has not yet been clarified. Here, we examined the roles of inflammatory cells in the pathogenesis of acute GVHD following UCBT, by expression profiling of a total of 595 genes in each of 4 subsets (CD4+, CD8+, CD14+, and CD56+) of peripheral blood mononuclear cells (PBMCs), which were taken from 3 patients with hematologic malignancy, in whom acute GVHD had developed after UCBT. We compared expression profiles measured during acute GVHD with those measured opon discharge (recovery phase), for each subset of PBMCs to identify immuno-regulatory genes which were assumed to be linked to the pathogenesis of acute GVHD. Keywords: disease state analysis Peripheral blood mononuclear cells (PBMCs) were taken from 3 patients with hematologic malignancy, in whom acute GVHD had developed after cord blood transplantation. CD4+, CD8+, CD14+, and CD56+ cell subsets were isolated from the PBMCs of 2 patients, while only CD8+ and CD56+ cell subsets were isolated from the PBMCs of a patient. PBMCs were taken twice - during acute GVHD phase and upon discharge (recovery phase), from each patient. By using a custom-made fibrous oligonucleotide DNA microarray Genopal (Mitsubishi Rayon), we compared expression profiles of 595 unique genes measured during acute GVHD with those measured upon discharge (recovery phase), for each subset of PBMCs.
