(Submitter supplied) 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. more...

(Submitter supplied) T-lymphocyte activation is efficiently mimicked in vitro by treatment with anti CD3 / anti CD28 antibodies. We report miR-21 induction upon CD3/CD28 stimulation of primary T-lymphocytes. In order to assess the function of miR-21 in T-lymphocytes we interfered with miR-21 function by lentiviral transduction of a miR-21 sponge construct. MRNA profile of miR-21 sponge and control transduced T-lymphocytes 48hrs after stimulation.

(Submitter supplied) The aim was to assess miRNA expression in 3 human ex-vivo CD8+ T cell subsets which span from antigen inexperienced cells (Naïve) 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 = naïve = CD8+, CCR7+, CD45RA+, CD45RO-, Tcm = central memory = CD8+, CCR7+, CD45RA-, CD45RO-,Tem= effector memory = CD8+, CCR7-, CD45RA-, CD45RO+

(Submitter supplied) In marmoset T cells transformed by Herpesvirus saimiri (HVS), a viral U-rich noncoding RNA, HSUR 1, specifically mediates degradation of host microRNA-27 (miR-27). High-throughput sequencing of RNA after crosslinking immunoprecipitation (HITS-CLIP) identified mRNAs targeted by miR-27 as enriched in the T-cell receptor (TCR) signaling pathway, including GRB2. Accordingly, transfection of miR-27 into human T cells attenuates TCR-induced activation of mitogen-activated protein kinases (MAPKs) and induction of CD69. more...

(Submitter supplied) The development and propagation of an adaptive immune response to an invading pathogen is a highly orchestrated process that involves the precise regulation of cytokine expression. Naïve CD4+ T lymphocytes give rise to T helper (Th) cell subsets with functions that are tailored to their respective roles in host defense. MicroRNAs are important regulators of most cellular processes, including many responses in the immune system. more...

(Submitter supplied) Primary biliary cholangitis (PBC), formally known as primary biliary cirrhosis, is an autoimmune liver disease of unknown pathogenesis. Consequently, therapeutic targets for PBC have yet to be identified. As CD4+ T cells play a pivotal role in immunological dysfunction observed in PBC, we analyzed microRNA(miRNA) and mRNA expression in CD4+ T cells to investigate PBC pathogenesis and identify novel therapeutic targets.

(Submitter supplied) MicroRNAs (miRNAs) are evolutionary conserved, non-coding, gene regulatory RNA molecules found in both plants and animals and amongst almost every cell and tissue type. They are about 22 nucleotides long and are involved in silencing of mRNA through sequence specific binding to the 3’ untranslated region (UTR) of the mRNA subsequently causing translational repression and/or will promote the degradation of protein-coding mRNA. more...

(Submitter supplied) T cell-specific deletion of PTEN induces premalignancy in CD4+ CD8+ (DP) immature T cells in the thymus, which progresses to the development of mature CD4+ T cell lymphomas in the lymph nodes and spleen. As part of a screen to identify factors that inhibit progression to malignancy, we compared miRNA expression in premalignant PTEN-deficient DP thymocytes versus wild-type controls.

(Submitter supplied) This study describes differential miRNA expression in small intestinal lamina propria leukocyte samples longitudinally during the course of SIV infection of rhesus macaques. Notably, the T-cell activation associated miR-15b, miR-142-3p, miR-142-5p and miR-150 expression was significantly downregulated at 90 and 180DPI. Further, reporter and overexpression assays validated IRAK1 as a direct miR-150 target. more...

(Submitter supplied) MicroRNAs (miRNAs) are noncoding RNAs of approximately 22 nucleotides in length that usually suppress the translation of target messenger RNAs (mRNAs) through partial complementarity to the 3¡¦ untranslated region (3¡¦ UTR) of protein-coding mRNAs in animals. However, there is increasing evidence that miRNAs can also reduce the steady-state levels of their target mRNAs in animals. In this investigation, both miRNA and mRNA profiles from the undifferentiated human embryonic stem cell line hES-T3 (T3ES), hES-T3 derived embryoid bodies (T3EB) and hES-T3 differentiated fibroblast-like cells (T3DF) were quantitatively determined. more...

(Submitter supplied) Buffy coats from four independent human donors were enriched for CD4+ cells using MACS CD4 beads and LS columns. Cells were subsequently sorted into Naïve, Central Memory and Effector Memory using following markers: Naive: CD4+CD25–CD45RA+CCR7+; Central Memory: CD4+CD25–CD45RA–CCR7+; Effector Memory: CD4+CD25-CD45RA-CCR7-. Total RNA from these cell subsets was extracted and 100ng was used for Nanostring SPRINT run according to manufacturer's instructions. more...
