Project description:GPR15+ vs GPR15- tumor-associated Tregs
| PRJNA713801 | ENA
Project description:GPR15 is an orphan G-protein coupled receptor and its expression is abundant among T cells in the large intestine lamina propria. We used microarrays to examine charateristics of GPR15- vs GPR15+ CD4+ T cells in LILP and identified distinct classes of up-regulated genes in GPR15+ CD4+ T cells. We have generated GFP knock-in mice in GPR15 locus and used GFP as a maker for GPR15 expression. In heterozygous mice, GPR15+CD4+ T cells and GPR15-CD4-T cells were sorted and RNA was prepared from them.

Project description:We performed RNA-seq analysis of Tregs isolated from Foxp3RFP/∆2Foxp3GFP-cre female mice. CD4+GFP+RFP+ (WT Tregs) and CD4+GFP+RFP- (Foxp3∆2 Tregs) cells were sorted from colon lamina propria to a typical purity of >95%. In order to obtain enough RNA for sequencing, we combined the cells sortd from the cLP of three mice for library construction. Genes that were upregulated (532 genes) and downregulated (497 genes) in Foxp3∆2 Tregs

Project description:EAE was induced in female FOXP3 fate mapping mice. At peak of disease, immune cells were isolated from brain and spinal cord (pooled as CNS) and spleen. Next, FOXP3+ and exFOXP3 T cells were FACS-sorted based on RFP and GFP expression.

Project description:The orphan chemoattractant receptor GPR15 is important for homing T lymphocytes to the large intestine, thereby maintaining intestinal immune homeostasis. However, the molecular mechanisms underlying the regulation of GPR15 expression remain elusive. Here we show a central role of the aryl hydrocarbon receptor (Ahr) in promoting GPR15 expression both in mice and human, thus gut homing of T lymphocytes. Mechanistically, Ahr directly binds to open chromatin regions of the Gpr15 locus to enhance its expression. Ahr transcriptional activity in directing GPR15 expression was modulated by two transcription factors, Foxp3 and RORγt, both of which are expressed preferentially by gut Tregs in vivo. Specifically, Foxp3 interacted with Ahr and enhanced Ahr DNA binding at the Gpr15 locus, thereby promoting GPR15 expression. In contrast, RORγt plays an inhibitory role at least in part by competing with Ahr binding to the Gpr15 locus. Our findings thus demonstrate a key role for Ahr in regulating Treg intestinal homing under the steady state and during inflammation, and the importance of Ahr-RORγt-Foxp3 axis in regulating gut homing receptor GPR15 expression by lymphocytes.

Project description:TIGIT+ Tregs suppress Th1 and Th17 responses while sparing Th2 responses. Analysis of global gene expression of TIGIT+ vs. TIGIT- Tregs from naive mice reveled that TIGIT+ Tregs display an activated phenotype and are enriched for Treg signature genes including the Treg effector molecule Fgl2 which enables them to selectively spare Th2 responses. TIGIT+ and TIGIT- Tregs were sorted from naïve Foxp3-GFP KI mice (pooled spleen and lymph nodes) TIGIT: T cell immunoreceptor with Ig and ITIM domains

Project description:Using Foxp3.RFP Rag.GFP reporter mice, mature Tregs in the thymus were characterized by performing RNA sequencing on Rag.GFP– and Rag.GFP+ Tregs that were isolated from the thymus and Tregs isolated from the spleen

Project description:A comparative analysis of gene expression of 3 different experiments; 1. Perinate or adult-tagged GFP+YFP+ and bulk GFP+YFP- Tregs, 2. FL or BM-derived Tregs 3. Perinate or adult thymic Tregs. 1. Foxp3-eGFP-Cre-ERT2 x Rosa26-YFP lineage-reporter mice were injected ip with tamoxifen (4 injections, every third day) between 0-10 (perinate) or 35-45 (adult) days of age, and keep until 8 weeks of age. Perinate or adult-tagged GFP+YFP+ cells and bulk GFP+YFP- were double-sorted. 2. Hematopoietic progenitor cells were isolated from E18.5 fetal liver of CD45.1 congenic mice or from bone marrow of 5 weeks old CD45.2 B6 mice via negative selection of Thy1.2+ cells. The two populations were mixed at a 1:1 ratio, and were iv-transferred into irradiated (1000 rad) Rag-1-KO mice. FL or BM-derived Tregs were double sorted after reconstitution. 3. Foxp3-GFP+ Tregs were double-sorted from perinate (4 days old) or adult (5 weeks old) thymi. RNA from whole samples was amplified, labeled, and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays.

Project description:Donminant negative transform growth factor receptor II (DNR) mice were served as a murine primary biliary cirrhrosis model. CD4+Foxp3+ Regulatory T cells (Tregs) play a critical role in self-tolerance and in regulating PBC. In order to determine whether DNR mice derived Tregs processed defective function compared with WT Tregs, CD4+Foxp3+ Treg cells were sorted from DNR and WT mice, respectively, then gene expression analysis was performed by using the Affymetrix GeneChip Mouse Genome 430 2.0 arrays CD4+Foxp3+ Tregs were sorted from the spleen of 10-week-old DNR mice and B6 wild-type mice, respectively. RNA of each sample was then extracted and hybridized on Affymetrix microarrays to detail differences between DNR Tregs and WT Tregs in gene expression.
