Project description:Human FOXP3+CD25+CD4+ regulatory T cells (Tregs) play a dominant role in the maintenance of immune homeostasis. Several genes are known to be important for murine Tregs, but for human Tregs the genes and underlying molecular networks controlling the suppressor function still largely remain unclear. We here performed a high-time-resolution dynamic analysis of the transcriptome during the very early phase of human Treg/ CD4+ T-effector cell activation. After constructing a correlation network specific for Tregs based on these dynamic data, we described a strategy to identify key genes by directly analyzing the constructed undirected correlation network. Six out of the top 10 ranked key hubs are known to be important for Treg function or involved in autoimmune diseases. Surprisingly, PLAU (the plasminogen activator urokinase) was among the 4 new key hubs. We here show that PLAU was critical for expression regulation of FOXP3, EOS and several other important Treg genes and the suppressor function of human Tregs. Moreover, we found Plau inhibits murine Treg development and but promotes the suppressive function. Further analysis unveils that PLAU is particularly important for memory Tregs and that PLAU mediates Treg suppressor function via STAT5 and ERK signaling pathways. Our study shows the potential for identifying novel key genes for complex dynamic biological processes using a network strategy based on high-time-resolution data, and highlights a critical role of PLAU in both human and murine Tregs. The construction of a dynamic correlation network of human Tregs provides a useful resource for the understanding of Treg function and human autoimmune diseases. The high-time-resolution time-series transcriptomic data during the very early phase of human Treg/Teff activation could be generally used for further mechanistic analysis of human Treg function. These data could be further used for biological network analysis, dynamic analysis, modeling by experimental researchers, bioinformaticians, computational biologists and systems biologists. We have measured the genome-wide expression of 38,500 genes (probes) by performing a high-time-resolution time-series analysis during the activation process of human regulatory T cells /CD4+ T-effector cells at 19 time points for the first 6h with an equal interval of 20 min. We have also overexpressed the GARP gene in human effector T cells and measured the genome-scale expression for the GARP-overexpressed cells and ThGFP cells at time point 0, 100 and 360min following activation. The stimulation source used in this work is a combination of anti-CD3/-CD28 Dynal beads with IL2 100U/ml.

Project description:To obtain the molecular signature of the effect that the IL-2 therapeutic dose induces on T cells in vivo, we performed gene array analysis. Since it was critical to perform this analysis on highly purified Tregs and Teffs, and also because activated Teffs can acquire CD25 expression, we used GFP-Foxp3 knock-in mice which allow for the purification of Tregs and Teffs based on the GFP expression. Illumina gene array was carried out on FACS sorted CD4+ GFP+ (Tregs) and CD4+ GFP- (Teffs) of mice that received either PBS or the curative schedule of IL-2, 2 hours after the last injection.<br><br>Further raw data files are available on the FTP site for this experiment.

Project description:Goals and objectives of this study: to identify genes preferentially induced in human CD4+CD25hi Treg cells following T-cell activation with potential role for stabililization & maintenance of the regulatory program. Keywords: T-cell receptor stimulation, gene-regulation, comparative gene expression profiling Homo sapiens CD4+CD25- and CD4+CD25hi T cells were sorted from healthy individual donors and analyzed ex vivo (non-activated) or 1 day following T-cell receptor activation using anti-CD3/IL2 and anti-CD3/-CD28/IL2 (activated), respectively.

Project description:The PI3K pathway has emerged as a key regulator of regulatory T cell (Treg) development and homeostasis and is required for full Treg-mediated suppression. To identify new genes involved in PI3K-dependent suppression we compared the transcriptome of WT and p110delta D910A Tregs. Among the genes that were differentially expressed was CD38. Here we show that CD38 is expressed mainly by a subset of Foxp3+CD25+CD4+ T cells originating in the thymus and on Tregs in the spleen. CD38high WT Tregs showed superior suppressive activity and CD38low Tregs failed to upregulate CD73, a surface protein which is important for suppression. However, Tregs from heterozygous CD38+/- mice were unimpaired despite their lower levels of CD38 expression. Therefore, CD38 can be used as a marker for Tregs with high suppressive activity and the impaired Treg function in p110delta D910A mice can in part be explained by the failure of CD38high cells to develop.

Project description:CD4+Foxp3+ regulatory T cells (Tregs) accumulate in skeletal muscle from dystrophin-deficient mdx mice. Analysis of global gene expression in muscles from mdx mice treated with anti-CD25 compared with muscles from mdx mice treated with control antibody revealed that Tregs partially protect mdx mice from muscle pathology and promote muscle repair/regeneration. Mdx mice received 2 ip injections of 100 mg of anti-CD25 mAb (clone PC61) or rat IgG (Jackson Immunoresearch) at days 17 and 20 of age. Muscles were dissected 7 days after the last injection.
