Expression data from Tregs purified from WT-CD3KO or IIKO-CD3KO chimeras

ABSTRACT: Disruption of TCR /MHC class II interactions leads rapidly to alterations of the common CD4 Treg transcriptional signature Self-deprived, non-functional Tregs were compare to fully functional Tregs by microarrays. CD3ε-/- mice were lethally irradiated and their immune system reconstituted with WT mouse (WT-CD3KO chimeras) or IIKO mouse (IIKO-CD3KO) Bone Marrow cells. Twenty eight days later, peripheral Tregs from these chimeras were purified for RNA extraction and hybridization on Affymetrix microarrays.

Expression data from self-deprived regulatory CD4 T cells

Project description:Disruption of TCR /MHC class II interactions leads rapidly to alterations of the common CD4 Treg transcriptional signature Self-deprived, non-functional Tregs were compare to fully functional Tregs by microarrays. Total T cells from the periphery of WT mice were adoptively transferred into CD3ε-/- recipient mice lacking or not MHC class II molecule expression (MHC II- or MHC II+ recipient mice, respectively). Five days later, peripheral Tregs transferred in MHC II - competent (CD4CD25B6) or - deficient (CD4CD25IIko) recipient were purified for RNA extraction and hybridization on Affymetrix microarrays.

Role of Adenosine 2A Receptors (A2AR) on regulatory T cells (Tregs)

Project description:The adenosine 2A receptor (A2AR) is expressed on regulatory T cells (Tregs), but the functional significance is currently unknown. We compared the gene expression between wild-type (WT) and A2AR knockout (KO) Tregs and between WT Tregs treated with vehicle or a selective A2AR agonist. FACS-sorted GFP positive Tregs from WT or A2AR KO FoxP3GFP mouse spleen and lymph nodes were incubated 18 hr with vehicle (DMSO), a separate set of WT Tregs were incubated with the selective A2AR agonist ATL1222 10 nM (Dogwood Pharmaceuticals, Inc.) for 18 hr prior to RNA isolation.

Gene expression profiling of murine WT and DNR Tregs

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.

Distinguishing innate memory CD8+ T from homeostatically expanded CD8+ T cells

Project description:Innate memory phenotype (IMP) CD8+ T cells are non-conventional αβ T cells exhibiting features of innate immune cells, and are significantly increased in the absence of non-receptor tyrosine kinase ITK. Their developmental path and function are not clear, particularly whether they can contribute to antigen specific responses. We found that WT bone marrow gives rise to IMP CD8+ T cells in irradiated MHCI-/- recipients, resembling those in Itk-/- mice determined by expression of surface markers. However, CD8+ T cells share similar expression of memory markers. We used microarrays to compare the global programme of gene expression to determine whether the CD8+ T cells selected by hematopoietic MHCI are IMP CD8+ T cells as observed in the absence of ITK, or the result of homeostatic expansion of T cell contamination in the donor bone marrow. Through analysis of global gene expression correlation and differential expression, we determined that hematopoietic MHCI dependent IMP CD8+ T cells generated in irradiated MHCI-/- recipients, resemble those in Itk-/- mice, but distinct from CD8+ T cells derived via homeostatic proliferation. Cell sorting was performed using a FACSAria Cell Sorter (BD Biosciences, San Diego, CA). IMP CD8+ T cells (TCRβ+CD8α+CD44hi) were sorted from splenocytes of WT→MHCI-/- chimeras 8 weeks post transplantation and 8-week old Itk-/- mice. To generate HP cells, naïve CD8+ T cells (TCRβ+CD8α+CD44lo) were sorted and injected into Rag1-/- recipients (0.5 million /mouse, retro-orbital injection), followed by sorting of TCRβ+CD8α+ splenocytes 8 weeks post adoptive transfer. We sought to compare cells with the same gender and age, thus all donors were female, and ages (absolute age for Itk null and age post transfer for chimeras and HP model) were 8 weeks.

TIGIT+ Tregs

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
