ABSTRACT: To investigate the function of Embigin on LTA1 induced-CD4+TRM cells, we immunized CD4cre x Embfl/fl mice with OmpX and LTA1 at Day0 and Day21, and isolated CD4+ cells from Embfl/fl CD4cre-(WT) and Embfl/fl CD4cre+(KO) mice from the lung by magnetic beads. We then performed gene expression profiling analysis using data obtained from RNA-seq of CD4+cells from 5 WT and 5 KO mice.
Project description:We report gene expression changes in Cul3 deficient thymic CD4+ T cells We used microarrays to detail the global programme of gene expression changes upon removal of Cul3 during thymic development CD25-, CD1dPBS57-, gdTCR - CD4+ Single positive cells from thymocytes of CD4Cre-Cul3fl/fl (LM) and CD4 Cre+Cul3fl/fl (KO) were sort purified and total RNA was extracted using Trizol and analysed by microarray.
Project description:A microarray study performed in iTreg of miR-31fl/fl/CD4Cre and control mice to identify genes that are regulated by the miR-31. CD4+ naïve T cells from miR-31fl/fl mice and miR-31fl/flCD4Cre mice were used to induce iTreg in vitro. Four independent experiments were performed.
Project description:Purpose: To compare the transcriptomes of activated CD4 T effector cell populations in the presence and absence of STAT3 at 8 days post-infection using high-throughput RNA sequencing analysis. Methods: Cell sorting of the populations was done using the markers Ly6c and PSGL-1 CD4 T cell Ly6c and PSGL-1 population mRNA profiles 8 days post-LCMV infection of wild type (WT) and STAT3fl/fl Cd4cre mice were generated by mRNA sequencing using Illumina HiSeq 2000.
Project description:Collagen type II-induced arthritis (CIA) is a disease, which includes inflammatory and autoimmune reactions. Spleen protein extracts were subjected to 2D-DiGE and MS-MALDI-TOF/TOF analysis to identify proteins that were different in concentration ally expressed in CD38-KO and B6 WT mice with arthritis or with inflammation. Using multivariate analyses, in Col-II-immunized mice 20 differentially expressed spleen protein species were able to discriminate between WT and CD38-KO mice. Among them, multiple serotransferrin (Tf) species were identified. In contrast, in CFA/IFA-treated mice, the distinct protein profile, which discriminates between CD38-KO and WT mice, was unrelated with Tf. Unexpectedly, non-immunized CD38-KO mice showed a distinct proteome profile as compared with that in non-immunized WT mice, and again multiple protein species were identified as Tf. By using a LC-TOF-MS method to separate and detect Tf glycopeptide glycoforms in serum samples, differences in the Tf glycosylation pattern between CD38-KO and WT mice sera were found in both non-immunized and CIA+ mice. Data on Tf spots separated by 2-DE indicate differences in glycosylation related with NeuGc content. In summary, Tf changed significantly in its glycosylation pattern in mice with arthritis
Project description:miRNA regulate gene expression at the post-transcriptionnal level. To gain further insight into this process, we analysed by Affymetrix microarray, the transcriptome of Dicer WT or Dicer deleted mouse CD4 T cells. Mouse CD4 T cells were sorted by flow cytometry from control CD4Cre neg Dicer lox/lox or CD4Cre pos Dicer lox/lox animals, total RNA was extracted using RNA bee and amplified before hybridization onto Mouse Gene arrays. Three biological replicate were analysed for each condition (3 Dicer WT control and 3 Dicer KO).
Project description:A microarray study performed in iTreg of miR-31fl/fl/CD4Cre and control mice to identify genes that are regulated by the miR-31. CD4+ naM-CM-/ve T cells from miR-31fl/fl mice and miR-31fl/flCD4Cre mice were used to induce iTreg in vitro. Four independent experiments were performed. MiR-31fl/fl/CD4Cre mice (6 wk old) and age-matched control mice were sacrificed, and the spleen were removed and teased into cell-single suspensions and filtered through a 40 M-NM-<m cell strainer. NaM-CM-/ve CD4+CD25-Foxp3gfp-CD62Lhi T cells were sorted by FACSAria III (BD bioscience).The medium used for T cell cultures was RPMI-1640 (Gibco) supplemented with 10% heat-inactivated FBS (Gibco), 2 mM L-glutamine (Gibco), 100 U/ml penicillin, 100 M-NM-<g/ml streptomycin, and 5 mM M-NM-2-mercaptoethanol (Gibco). The CD4+ NaM-CM-/ve T cells were stimulated with plate-bound anti-CD3 (5 M-NM-<g/ml) plus soluble anti-CD28 (2 M-NM-<g/ml) under iTreg cell differentiation conditions (mTGF-M-NM-21, 5 ng/ml and rmIL-2, 40 ng/ml; R&D Systems). After 4 days, harvested cell ,the RNA was extracted in Trizol and then purified using the miRNeasy Micro Kit (Qiagen). This submission shows the data obtained from 3 individual miR-31fl/fl/CD4Cre mice mice measured against 3 control mice.
Project description:To investigate the function of Bcl11b in activated C57Bl/6 mouse CD4+ T cells, we deleted Bcl11b in vivo using a Bcl11b-fl/fl;Cd4cre-ert2 tamoxifen-inducible strategy. We then cultured CD4 T cells isolated from these mice 3 days in resting or activating condtions. Finally, we performed gene expression profiling analysis using data obtained from RNA-seq of 3-5 samples per genotype per condition.
Project description:To characterize the effect of loss of Ets1 in Non-TFH and TFH cells, we performed gene expression RNAseq analysis for T follicular helper (TFH) and Non-T follicular helper (Non-TFH) cells in WT (Ets1 fl/fl) and Ets1 KO (CD4-cre Ets1 fl/fl) mice.
Project description:This study investigates the role of store-operated calcium entry (SOCE) in T cell-mediated immune responses to pulmonary influenza A virus (IAV) infection and allergic airway inflammation after immunization by house dust mite (HDM) allergens. We conducted a comparative gene expression analysis of antigen-specific CD4+ T cells from wildtype (WT) and Orai1fl/fl Cd4Cre mice that were adoptively transferred to TCRalpha knockout mice followed by sensitization / challenge with HDM or infection with influenza A virus (IAV) strain x31. Donor CD4+ T cells were isolated from the lungs of host mice at days 9 (IAV) and 14 (HDM), RNA was isolated and processed for bulk RNA sequencing.
