Project description:Themis1, a recently described T-lineage specific protein, is essential for thymic positive and negative selection. Although Themis1 has been clearly identified as a component of the T cell antigen receptor (TCR) signalosome, its precise role in TCR signaling remains unclear. Here, we used quantitative proteomic and TCR signaling reporter mice to gain insight into Themis1 signaling function. Mass spectrometry analysis of the Themis1 interactome identified Grb2, SHP1 and Vav1 as the principal interacting partners of Themis1 in thymocytes. The dataset contains mass spectrometry results from the analysis of 6 different kind of AP-MS purifications (based on immunoprecipitation using a Themis1 antibody) starting from the following samples: - thymocytes from WT mice, non stimulated (noted WT NS) - thymocytes from WT mice, stimulated with pervanadate (noted WT P) - thymocytes from GRB2 +/- mice (with decreased expression of GRB2), non stimulated (noted GRB2 NS) - thymocytes from GRB2 +/- mice (with decreased expression of GRB2), stimulated with pervanadate (noted GRB2 P) - thymocytes from Themis1 -/- mice (knock-out for Themis1), non stimulated (noted KO NS) - thymocytes from Themis1 -/- mice (knock-out for Themis1), stimulated with pervanadate (noted KO P) Three biological replicates were prepared for these 6 different conditions (noted, 1,2,3), yielding 18 analyzed samples. Three technical nanoLC-MS runs were acquired for each sample (noted R1, R2, R3), leading to the 54 nanoLC-MS raw files contained in the dataset.

Project description:To gain a molecular view of E-proteins with respect to the development of Foxp3+ T cells, we perform microarray studies that would identify transcription factors that are up-regulated as E-proteins levels fall and and Foxp3 expression rises. We hypothesize that such transcription factors activate the synthesis of key proteins necessary for the development of Foxp3+ cells in the thymus (or in the periphery). Among the possible proteins (negatively regulated by E-protein are those involved in IL-2 signaling, since the latter has been shown to be critical for the development of Foxp3+ cells in the thymus. In the planned studies we will extract mRNA from sorted Foxp3+GFP+ thymocytes from wild type (WT) mice and similar cells from E-protein deficient thymocytes. However, since Foxp3+ thymocytes in WT mice already have reduced E-protein levels, differences between thymocytes from these mice and E-protein deficient mice might be minimal. We therefore will also extract mRNA from Foxp3-negative thymocytes from WT mice whose E-proteins levels have not fallen sufficient low to allow Foxp3 expression and Foxp3-negative thymocytes from E-protein deficient mice whose E-proteins are necessarily low but have not expressed Foxp3 for unrelated reasons.

Project description:T cell development is accompanied by epigenetic changes that ensure the silencing of stem cell-related, and the activation of lymphocyte-specific programs. How transcription factors influence these changes remains unclear. We show that the Ikaros transcription factor interacts with the Polycomb Repressive Complex 2 (PRC2) in CD4-CD8- thymocytes, and allows its binding to >200 developmentally-regulated genes, many of which are expressed in hematopoietic stem cells. Loss of Ikaros in CD4-CD8- cells leads to diminished histone H3 Lys27 (H3K27) trimethylation and ectopic expression of these genes. Ikaros binding triggers PRC2 recruitment and H3K27 trimethylation. Furthermore, Ikaros interacts with PRC2 independently of the Nucleosome Remodeling and Deacetylation complex. Our results identify Ikaros as a fundamental regulator of PRC2 function in developing T cells.
