Project description:Activation of the T cell-mediated immune response has been associated with changes in the expression of specific miRNAs. However, the role of miRNAs in the development of an effective immune response is just beginning to be explored. Here we report a microRNA expression profile showing a list of microRNAs, which are highly up-regulated or down-regulated in human memory T cells compared to naive T cells, thus suggesting a possible role of these microRNAs in T lymphocyte differentiation. Keywords: Primary Tissue miRNA Expression profile We used microarrays to profile miRNA expression in human naive and central memory CD4+ and CD8+ T lymphocytes

Project description:Gene expression data of primary human naive and memory CD4+T lymphocytes purified from peripheral blood are generated to be analyzed in different ways such as for traditional searching of differentially expressed genes between the two cell subsets or in combination to in-silico data of microRNAs target prediction for microRNAs known to be characteristically expressed in the two cell subsets. Two cell subsets (cell types) FACS purified from peripheral blood of six samples/healthy donors (samples #3,5,6,7,026,065). Naive CD4+ T cells were extracted from all 6 samples and 6 biological replicas were obtained (3N, 5N, 6N, 7N, 026N, 065N), while memory CD4+T cells were extracted from 4 samples and 4 biological replicas were obtained (3m, 5m, 6m, 7m). Both naive and memory replicas from samples 3, 5, 6 and 7 were hybridized onto two beadsarrays each while those from samples 026 and 065 were hybridized on 1 beadsarray each (for a total of 18 beadsarrays used). For analysis purposes naive cells samples 3N, 5N, 6N and 7N can be considered paired with memory samples 3m, 5m, 6m and 7m respectively, since they are obtained from the same blood samples/healthy donors.

Project description:Comparsion of the transcriptomes of naive, resting memory and activated memory CD4+ T lymphocytes. Peripheral blood lymphocytes were collected at baseline and day 13 post-inoculation of a healthy subject administered with vaccinia virus. Cells were isolated by FACs using antibodies against CD4, CD45RO and CD38.

Project description:Comparison of the transcriptome of naive (CD45RA+ CD27+) and differentiated (CD27-CD28-) CD4+ lymphocytes from newborns with congenital human cytomegalovirus infection (cord blood samples) and pregnant women diagnosed with primary CMV infection. Naive cells from HCMV uninfected newborns were used as a control.

Project description:Naive CD4+ T cells are the common precursors of multiple effector and memory T cell subsets and possess a high plasticity in terms of differentiation potential. This stem-cell like character is important for cell therapies aiming at regeneration of specific immunity. Cell surface proteins are crucial for recognition and response to signals mediated by other cells or environmental changes. Knowledge of cell surface proteins of human naive CD4+ T cells and their changes during the early phase of T cell activation is urgently needed for a guided differentiation of naive T cells and may support the selection of pluripotent cells for cell therapy.<br>Periodate oxidation and aniline-catalyzed oxime ligation (PAL) technology was applied with subsequent quantitative LC-MS/MS (PAL-qLC-MS/MS) to generate a dataset describing the surface proteome of human naive CD4+ T cells and to monitor dynamic changes during the early phase of activation. This led to the identification of 173 N-glycosylated surface proteins, of which 24 were previously not known to be expressed on human naive CD4+ T cells or have no defined role within T cell activation. To independently confirm the proteomic dataset and to analyse the cell surface by an alternative technique a systematic phenotypic expression analysis of surface antigens via flow cytometry was performed. This screening expanded the previous dataset, resulting in 229 surface proteins which are expressed on naive unstimulated and activated CD4+ T cells. Furthermore, we generated a surface expression atlas based on transcriptome data, experimental annotation and predicted subcellular localization, and correlated the proteomics result with this transcriptional dataset.<br>This extensive surface atlas provides an overall naive CD4+ T cell surface resource and will enable future studies aiming at a deeper understanding of mechanisms of T cell biology allowing the identification of novel immune targets usable for the development of therapeutic treatments.
