Project description:Human Naïve-like CD8 T cells induced by the Yellow Fever Vaccine 17D were compared to the conventional subsets in total CD8 T cells Samples originate from peripheral blood mononuclear cells (PBMC) from 8 different donors vaccinated with the YF-17D vaccine 1'000 cells from various CD8 T cells subsets were purified by flow cytometry, from 8 vaccinees (donors d1 to d8); the subsets (cell types) include: A2/NS4b tetramer positive CCR7+ CD45RA+ CD8 T cells (A2_NS4b Naïve-like), Total Naive (CCR7+ CD45RA+), Total Tscm (CCR7+ CD45RA+ CD58+ CD95+), Total CM (CCR7+ CD45RA-) and Total Effectors (CCR7 negative).

Project description:The aim was to assess miRNA expression in 3 human ex-vivo CD8+ T cell subsets which span from antigen inexperienced cells (NaM-CM-/ve) to early memory cells (central memory, Tcm) and later stage memory cells (effector memory, Tem) CD8+ T cells were sorted on a FACS Aria II machine. N = naM-CM-/ve = CD8+, CCR7+, CD45RA+, CD45RO-, Tcm = central memory = CD8+, CCR7+, CD45RA-, CD45RO-,Tem= effector memory = CD8+, CCR7-, CD45RA-, CD45RO+ PBMC were isolated from 3 healthy human donors and sorted by FACS into 3 CD8+ T cell subsets. Total RNA was purified using the miRVANA kit (Ambion)

Project description:Epigenetic therapy overcame alemtuzumab resistance in patients with relapsed T-cell prolymphocytic leukemia and induced the expression of treatment related genes. Method: patient PBMCs from Ficoll, normal patient PBMCS enriched for CD3+/CD8+ or CD3+/CD8+/CD45RA+/CCR7- were extracted in Trizol. Conclusion: Gene expression profiles were changed by epigenetic therapy, likely activating treatment response genes silenced by carcinogenesis. Total RNA from patient Peripheral Blood Mononuclear Cells (PBMC) or from normal negatively enriched CD3+/CD8+/CCR7-/CD45RA+(CD45RO-) blood

Project description:To examine the broad impact of IL-27 on human T lymphocytes, we performed a microarray analysis assessing >20,000 well annotated genes on purified naïve (CD45RA+CD45RO-CCR7+) and central memory (CD45RA-CD45RO+CCR7+) CD4+ and CD8+ T cells from three healthy donors that were activated in vitro (plate bound anti-CD3 and soluble anti-CD28) in the presence or absence of human recombinant IL-27 (100 ng/mL). Our goal was to investigate the impact of interleukin-27 on the gene expression profil of human CD4 and CD8 T lymphocytes.

Project description:Cells were isolated from healthy human donors (n=2). Unstimulated cells. Cells were stained with CD4, CD45RA, CCR7 and CXCR7. Using flow cytometry, 4 CD4+ T cell populations were sorted: (1) Naïve (CD45RA+CCR7+CXCR5-), (2) Central memory (CD45RA-CCR7+CXCR5-), (3) Effector memory (CD45RA-CCR7-CXCR5-) and (4) CXCR5+ cells (CD45RA-CCR7-CXCR5+)

Project description:To understand the regulation of cytotoxicity by decidual CD8+ T cells (CD8+ dT) at the maternal-fetal interface, gene expression analysis of CCR7-CD45RA- effector-memory CD8+ T cells isolated from peripheral blood of unrelated healthy controls and decidual tissue from first trimester (6-12 weeks) and term (>37 weeks) pregnancy was performed. Furthermore, first trimester decidual effector-memory CD8+ T cells were stimulated with anti-CD3/CD28 in the presence of IL-2 for 12 hours or 72 hours. RNA was isolated and gene expression profiles were generated by employing Affymetrix HG_U133_Plus 2 arrays on the Affymetrix Geneatlas system.

Project description:Human CD8+ T cells are functionally heterogeneous and can be divided into distinct subsets according to CCR7 and CD45RA expression levels. Among the subsets, CCR7-CD45RA+ CD8+ T cells are considered to be terminally differentiated cells and designated as Temra. Temra show attenuated ability to proliferate and produce IFN-gamma in response to TCR stimulation, while Temra show improved function after IL-15 treatment. To clarify the transcriptional signatures induced by the stimulations, Temra were purified using flow cytometry, stimulated with IL-15 or with anti-CD3/CD28 (TCR stimulation), or cultured without stimulation for 2 days, and subjected to microarray analysis.
