Transciptional profile analysis of the gonadal (peri-uterine) white adipose tissue of pregnant mice

Project description:In this study we performed RNA sequencing to determine the transcriptome of the gonadal white adipose tissue of pregnant wild type mice. We further assessed, using conditional RankΔFoxn1 knockout mice (which lack expression of Rank in the thymic epithelia), how the expression of the receptor Rank in the thymic medullary epithelia affects the transcriptional program of this tissue during pregnancy, and whether adoptive transfer of natural regulatory Tregs can rescue the alterations observed in the RankΔFoxn1 dams. For this study, we isolated at day E17.5 of pregnancy, the gonadal (peri-uterine) white adipose tissue of wildtype RankWt as well as of RankΔFoxn1 dams pregnant females that were treated at days E0.5-2.5 of pregnancy with either vehicle (PBS) or with 1x105 sorted-purified wild-type natural Tregs isolated from RankWt pregnant E7.5-8.5 donors (denoted as RankΔFoxn1_Treg). For the isolation of viable Tregs for the transplant, we generated RankWt dams that express GFP from the Foxp3 promoter (by crossing to reporter mice), and use the expression of GFP to mark and isolate bona fide Tregs and, in addition, Neuropilin1 to denote the thymic origin of the Tregs. Of note, RankWt as well as of RankΔFoxn1 dams mice also carried the GFP-Foxp3 transgene and where treated with vehicle solution (PBS) at day E0.5-2.5. Total RNA was extracted from the isolated gonadal white adipose tissue of the three described cohorts (RankWt_veh, RankΔFoxn1_veh, and RankΔFoxn1_Treg) and analyzed by Quant-seq. Our study shows how the presence of Rank receptors in the thymic epithelium, functioning via natural Tregs, regulate the inflammatory and metabolic pathways implicated in adipose tissue biology during pregnancy.

IFNg+ vs IFNg- Treg

Project description:Gene expression studies comparing IFNg+ Tregs versus IFNg- Tregs from human peripheral blood Ex vivo sorted Tregs (CD25highCD127neg) were stimulated for 4 hours and IFNg-secreting cells were detected by a IFNg-capture kit. The samples were resorted based on IFNg expression.

Gene expression by Treg subsets

Project description:Thymic-derived natural T regulatory cells (nTregs) are characterized by functional and phenotypic heterogeneity. Recently, a small fraction of peripheral Tregs have been shown to express Klrg1, but it remains unclear the extent Klrg1 defines a unique Treg subset. Here we show that Klrg1+ Tregs represent a terminally differentiated Treg subset derived from Klrg1- Tregs. This subset is a recent antigen-responsive and a highly activated short-lived Treg population that expresses enhanced levels of Treg suppressive molecules and that preferentially resides within mucosal tissues. The development of Klrg1+ Tregs also requires extensive IL-2R signaling. This activity represents a distinct function for IL-2, independent from its contribution to Treg homeostasis and competitive fitness. These and other properties are analogous to terminally differentiated short-lived CD8+ T effector cells. Our findings suggest that an important pathway driving antigen-activated conventional T lymphocytes also operates for Tregs. Gene expression analysis was performed of this and other Treg subsets based on expression of CD62L, CD69, and Klrg1 to define the molecular properties of Klrg1+ Tregs and its relationship to other Treg subsets found in the peripheral immune tissues. Mice were euthanized, spleen cell preparations were made, and each Treg subset was isolated by FACS cell sorting. RNA was immediately prepared for processing.
