Project description:Tregs from spleen and thymus of naive Wild-type mice and mice lacking Dendritic Cells (deltaDC) were analyzed. Thymus derived Tregs of both strains show similar expression patterns, peripheral splenic Tregs from deltaDC mice differ from Tregs of WT mice.
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.

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. 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.
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
