Description
To understand the nature of glucocorticoids targeting non-immune cell function, we generate RNA sequencing data from 3 human podocyte cell lines derived from 3 kidney transplant donors and identify the genes that are significantly regulated in dexamethasone-treated podocytes compared to vehicle-treated cells.Our results represent a significant step forward in the genome-wide characterization of the molecular effects of glucocorticoids on human podocytes. The resource generated in this study is important for understanding the targeting of non-immune cell function by glucocorticoids and also for designing more specific podocyte-targeted agents for MCN therapy. Overall design: Transcriptome profiles of human podocytes treated with vehicle and dexamethasone were generated by RNA-sequencing using Illumina HiSeq 2500

Description
Co-stimulatory molecules of the CD28 family on T lymphocytes integrate cues from innate immune system sensors, and modulate activation responses in conventional CD4+ T cells (Tconv) and their FoxP3+ regulatory counterparts (Treg). To better understand how costimulatory and co-inhibitory signals might be integrated, we profiled the changes in gene expression elicited in the hours and days after engagement of Treg and Tconv by anti-CD3 and either anti-CD28, -CTLA4, -ICOS, -PD1, -BTLA or -CD80.

Description
We report transcriptional characterization of skeletal muscle macrophage subsets in normal and injured muscle after intramuscular injection with cardiotoxin. We profiled transcriptional differences in macrophage subsets from mice depleted of Treg cells using Foxp3-DTR mice. We uncovered an IFN-g-centered regulatory loop, in which Treg cells inhibit NK and T cells to control macrophage accumulation and phenotype during muscle regeneration.

Description
This study was performed to understand what controls the aggressivity of the pancreatic infiltrate during type-I diabetes development. We used the BDC2.5 transgenic mouse model. Samples were obtained at the age of onset of insultis. Depending on their genetic background, mice transgenic for the BDC2.5 T cell receptor present very different forms of insulitis. The NOD genetic background leads to a benign insulitis whereas the C57Bl/6-H2g7/g7 leads to an aggressive insulitis. We first studied how antigen-specific T cells are affected by these differences by obtaining the transcriptional profiles of BDC2.5 T cells from pancreas and pancreatic lymph nodes. We also compared the gene expression profiles of the entire leukocyte population present in the pancreatic lesion.

Description
Three innate (B1-B, NKT, CD8aaT cells) and adaptive (B2-B, CD4T, CD8abT cells) cell-types were sorted by FACS. Three biological replicates for NKT, CD4T, CD8aaT, CD8abT cells and two biological replicates for B1 and B2 cells were generated and the expression profiles were determined using Affymetrix Mu74Av2 chip. Comparisons between the sample groups allow the identification of genes differentially expressed between the innate and adaptive cell-types.

Description
The aim of this study was to determine the effect of transgenic Aire expression on the transcriptional profile of a tissue that normally does not express Aire: pancreatic islets. The transcriptional profile of transgenic RIP-Aire27 islets was compared to non-transgenic littermate islets as well as to archival NOD thymic medullary epithelial cells (MEC) data. All data were from non-obese diabetic (NOD) mice

Description
The first T cells to arrive in the liver were mostly T regulatory (Treg) cells and metabolically active, highly proliferative T conventional (Tconv) cells. The Tconv cells had unusually high expression of PD-1 and the IL-33 receptor, ST2. As these PD-1+ Tconv cells accumulated in the tissue, they gradually lost their expression of ST2, ceased to proliferate and acquired an anergic phenotype. Overall design: Gene expression profiles of flow cytometry sorted DAPI negative CD45 positive TCRb positive CD4 positive Foxp3 negative cells from liver of 5- and 10-day-old B6.Aire-KO mice

Description
The CD4+Foxp3+ regulatory T cells play an essential role in maintaining tolerance via their suppressive function on conventional T cells. The intracellular signaling pathways that regulate Foxp3 expression are largely unknown. In this study we describe a novel inhibitory role for AKT in regulating de novo induction of Foxp3 both in vivo and in vitro. A constitutively active allele of AKT significantly diminished TGF- induced Foxp3 induction via a rapamycin-sensitive pathway, establishing a role for the AKT-mTOR axis in Treg cells. Moreover, the observed impairment in Foxp3 induction was paralleled by a selective downmodulation of the imparted Treg transcriptional signature highlighting the importance of the balance of intracellular signals in Treg differentiation . Our results provide a basis for further elucidation of molecular mechanisms that regulate Foxp3 induction and identify AKT as an important negative regulator of this process.
