Description
We identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To establish the role of Pparg in shaping the VAT Tregs gene profile and cell dynamics, Tregs from lymph nodes and visceral adipose tissue of mice sufficient and deficient of Pparg expression in Tregs were double sorted for microarray analysis.

Description
We identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To explore the contribution of Pparg1 and 2 in the generation of the VAT Tregs-specific gene signatures, CD4+FoxP3- T cells were transduced with Foxp3+/- Pparg1 (or Pparg2), treated with Pioglitazone or vehicle, and double sorted for microarray analysis.

Description
The NOD (nonobese diabetic) mouse strain develops a characteristic autoimmune syndrome that closely resembles human type I diabetes. It has been suggested that NOD mice exhibit both numerical deficiency in CD4+CD25+ regulatory T cells (Treg) and reduced suppressive activity. We compared sorted CD4+CD25+ Tregs from the spleens of 6-7 week-old female NOD and nondiabetic B6.H2g7 mice. Tregs were 932% and 951% Foxp3+ in NOD and B6.H2g7 cells, respectively, on post-sort reanalysis. "Conventional" CD4+CD25- T cells (Tconv) are included as reference populations. Surprisingly, Treg "signature" is similar between the two strains, with only a few probesets that subtly deviate.

Description
The transcription factor Foxp3 is usually considered the master regulator for the CD4+CD25+ "Treg" lineage, which plays a key role in controlling immune and autoimmune responses, and is characterized by a unique transcriptional signature. We have performed a meta-analysis of this signature in Treg cells in several conditions to delineate the elements that can be ascribed to T cell activation, TGFbeta signaling, or Foxp3 itself. We find that these influences synergize to activate many of the signatures components. Foxp3 and TGFbeta signaling have interconnected relationships, as Foxp3 is induced by TGFbeta while enhancing TGFbetas positive feedback loop. Much of the Treg signature cannot be ascribed to Foxp3, as it contains gene clusters that are co-regulated, but cannot be transactivated, by Foxp3. This suggests that the Treg lineage is specified at a higher level of regulation, upstream of Foxp3, which does control some of the lineages essential immunoregulatory attributes.

Description
The presence of different types of immune cells in adipose tissue has been demonstrated in numerous studies. Whereas cells of the immune system in white adipose tissue contribute to the low-grade chronic inflammation under obese conditions, their function in brown adipose tissue (BAT) remains largely elusive. Here we report a role of regulatory T (Treg) cells in BAT physiology.Ablation of Treg cells resulted in massive invasion of macrophages into BAT concordant with rearrangement of BAT morphology. Treg ablated animals displayed reduced energy expenditure. Our results for the first time demonstrate a functional role of Treg cells in the regulation of energy homeostasis.

Description
Comparisons of global gene-expression profiles revealed a greater distinction between CD4+ Treg cells and CD4+ conventional (Tconv) T cells residing in abdominal (epidydimal) fat versus in more standard locations such as the spleen, thymus and LN.

Lean, but not obese, fat is enriched for a unique population of regulatory T cells that affect metabolic parameters.
