Description
We performed total RNA-Seq of murine Th1 cells which were four times reactivated in vitro in the presence of irradiated APC'srepeatedly activated in vitro. Overall design: CD4+CD62Lhi (naive) cells were isolated from C57BL/6 mice, activated with aCD3 and aCD28 an cultured under Th1 polarizing conditions in the presence of irradiated APCs. Every sixth day cells were harvested, restimulated with aCD3 and aCD28 and cultured under Th1 polarizing conditions in the presence of irradiated APCs APCs. After four rounds of restimulation, total RNA was extracted and cDNA libraries for total RNA sequencing were generated using “TruSeq® Stranded Total RNA Library” kit (Illumina, San Diego, CA, USA).

Gene expression profiling of cells isolated ex vivo is a unique tool to assess gene expression in vivo. Exemplified for CD4+CD45RO+ effector/memory T helper (T E/M) lymphocytes of human peripheral blood, we have analyzed different isolation procedures and storage conditions for the introduction of bias.

Description
CD4+ T lymphocytes are key to immunological memory, but little is known about the lifestyle of memory CD4+ T lymphocytes. We showed that in the memory phase of specific immune responses to antigens, most of the memory CD4+ T lymphocytes relocated into the bone marrow (BM) within 3-8 weeks after their generation, a process involving integrin a2. Antigen-specific memory CD4+ T lymphocytes expressed Ly-6C to a high degree, unlike most splenic CD44hiCD62L- CD4+ T lymphocytes. In adult mice, more than 80% of Ly-6Chi CD44hiCD62L- memory CD4+ T lymphocytes were in the BM. In the BM, they are located next to IL-7-expressing VCAM-1+ stroma cells, and were in a resting state. Upon challenge with antigen, they rapidly expressed cytokines and CD154 and induced the production of high-affinity antibodies, indicating their functional activity in vivo and marking them as professional memory T helper cells

Description
PreB cells were analyzed for differences in gene expression before and after the overexpression of miR-221. In order to dissect possible targets for the miR-221, gene expression profiles of preB cells un-induced or induced for the miR-221 expression after 8, 16 and 24 hours were compared. All induction time-points, e.g. after 8, 16 and 24 hours were compared to un-induced preB cells and to each other group.

Description
This study demonstrates quantitative and qualitative differences between type I IFN signatures in autoimmunity and viral infection using purified CD4pos T cells and CD16pos- and CD16neg-monocyte subsets. We were able to discriminate between cell-specific viral response signatures and the pathogenically amplified IFN signatures observed in autoimmunity. The differences were of both a qualitative and quantitative nature, as the signatures in the patients with SLE were characterized by much more complexly compiled gene patterns with increased absolute gene expression levels.

Description
To udnderstand the tissue-resident features of antigen-specific memory T cells of the bone marrow and spleen, we performed RNA-Seq and compared expression levels of genes of resting LCMV.GP66-77 specific CD4 T cells isolated from bone marrow (BM) and spleen of LCMV.GP61-80 primed C57BL/6 mice. Overall design: C57BL/6 mice were primed at day 0 with LCMV.GP61-80-NP-MSA + poly(I:C) and immunized again at day 14 with LCMV.GP61-80 + poly(I:C). Sixty days after the last immunization mice were sacrificed and LCMV.GP66–77-specific CD69+ and CD69- memory CD4 T cells were isolated from BM and spleen.

Description
The basic helix-loop-helix transcriptional repressor twist1, as an antagonist of nuclear factor B (NF-B)-dependent cytokine expression, is involved in the regulation of inflammation-induced immunopathology. We could show that twist1 is expressed by activated T helper (Th) 1 effector memory cells. Induction of twist1 in Th cells is dependent on NF-B, nuclear factor of activated T cells (NFAT), and interleukin (IL)-12 signaling via signal transducer and activator of transcription (STAT) 4. Expression of twist1 is transient following T-cell receptor engagement, and increases upon repeated stimulation of Th1 cells. Imprinting for enhanced twist1 expression is characteristic of repeatedly restimulated effector memory Th cells and thus of the pathogenic memory Th cells of chronic inflammation. Th lymphocytes from the inflamed joint or gut tissue of patients with rheumatic diseases, Crohns disease or ulcerative colitis express high levels of twist1. Expression of twist1 in Th1 lymphocytes limits the expression of the cytokines interferon-, IL-2 and tumor necrosis factor-, and ameliorates Th1-mediated immunopathology in delayed-type hypersensitivity and antigen-induced arthritis. In order to identify the effect of twist1 expression on the function of Th cells, twist1 was ectopically expressed and the transcriptome was compared to empty-virus infected control cells. In addition, this experiment allows for the identification of genes regulated by the transcription factor twist1.
