Next Generation Sequencing Facilitates Quantitative Analysis of adipose tissue Treg and LN Treg Transcriptomes

ABSTRACT: The goal of this study is to reveal unique features of adipose Tregs and to study mechanisms underlying how mediator Med23 regulate adipose Treg function in aged mice. Therefore, mRNA profiles of LN Tregs (from 4-month old Foxp3Cre mice) and adipose Tregs (from 4-month old Foxp3Cre, 4-month old obese Foxp3Cre, 10-month old Foxp3Cre and 10-month old Med23fl/fl;Foxp3Cre mice) were generated by deep sequencing, single experiment, using Illumina HiSeq2000. We compared transcriptome features between lymph node-derived Tregs and adipose Tregs from 4-month old lean or obese mice. Using unbiased comparative gene expression analyses, we found adipose Tregs display an up-signature of Insr (Insulin receptor) and Hif1a, while Pparg acts as a positive control. We next compared gene expression profiles of adipose Tregs from 10-month old Med23fl/fl;Foxp3Cre (MKO) and Foxp3Cre (WT) mice. adipose Med23-ΔTreg cells display impaired transcription of Pparg and Il1rl1 (ST2), and they simultaneously acquire the expression of Nt5e (CD73), while Entpd1 (CD39) expression was not dramatically altered. Our studies implicate protective roles of CD73hi adipose Tregs and offer new therapeutic strategies against age-associated metabolic syndrome.

Next Generation Sequencing Facilitates Quantitative Analysis of Adipose Tregs from Foxp3Cre and Hif1afl/fl;Foxp3Cre mice

Project description:The goal of this study is to study mechanisms underlying how HIF-1α regulates adipose Treg function. Therefore, mRNA profiles of adipose Tregs (from 4-month old Foxp3Cre and Hif1afl/fl;Foxp3Cre mice) were generated by deep sequencing, single experiment, using Illumina HiSeq TEN. We compared gene expression profiles of adipose Tregs from Hif1afl/fl;Foxp3Cre and Foxp3Cre mice. Using unbiased comparative gene expression analyses, we found adipose HIF-1α-ΔTreg cells showed higher expression of Nt5e gene and simultaneously down-regulated canonical adipose Treg genes (including Pparg, Il1rl1, Klrg1, Areg). Therefore, these data suggested a dependency of HIF-1α on PPAR-γ expression in adipose Tregs.

Single-cell sequencing of wt and Rbx1-deficient Treg cells from mice

Project description:Single-cell RNA sequencing (scRNA-seq) was utilized to unbiasedly dissect the cellular heterogeneity of wt vs. Rbx1-deficient CD4+YFP+ Treg cells from the peripheral lymph nodes of inflammation-free female Foxp3cre/wt and Foxp3cre/wt;Rbx1fl/fl mice.

Gene expression profile of regulatory T cells (Tregs) isolated from visceral adipose tissue and lymph nodes of mice sufficient and deficient of Pparg expression in Tregs

Project 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. All gene expression profiles were obtained from highly purified (double-sorted) T cell populations sorted by flow cytometry. To reduce variability, cells from multiple mice were pooled. Triplicates were generated for all groups. Raw data were preprocessed with the RMA algorithm in GenePattern and averaged expression values were used for analysis.

Transcriptomic analysis of Treg and Tconv cells from inflamed tissues of mice that are deficient for TNFR2 in Treg cells

Project description:Methods: Foxp3Cre-ERT2 x Tnfrsf1bFlox/Flox (icKO) and Foxp3Cre-ERT2 control (Ctrl) mice were immunized with MOG35-55 peptide to induce active EAE. From day 7 to 14, they were treated with Tamoxifen to delete TNFR2 only in Tregs. At day 14, Tregs and Tconvs were purified by flow cytometry from the inflamed central nervous system (CNS) or draining lymph nodes (dLN) for RNA extraction Results: In the CNS, TNFR2-deficient Tregs have lower expression of several Treg cell-signature genes and increased expression of genes normally expressed by Tconvs. The expression of 185 and 229 genes was respectively down- and up-regulated in Tconvs isolated from the CNS of mutant animals, compared to controls. Tconvs from icKO mice displayed a highly activated phenotype.

PPARg marks splenic precursors of multiple nonlymphoid-tissue Treg compartments [scTCR-seq]

Project description:Foxp3+CD4+ regulatory T cells (Tregs) regulate most types of immune response as well as several processes important for tissue homeostasis – for example, metabolism and repair. Dedicated Treg compartments – with distinct transcriptomes, T-cell-receptor repertoires, and growth/survival factor dependencies – have been identified in several nonlymphoid tissues. These Tregs are specifically adapted to function and operate in their home tissue – when, where and how do they take on their specialized characteristics? We recently reported that a splenic Treg population expressing low levels of the transcription factor, PPARg, contains precursors of Tregs residing in visceral adipose tissue. This finding made sense given that PPARg, the “master-regulator” of adipocyte differentiation, is required for the accumulation and function of Tregs in visceral adipose tissue but not in lymphoid tissues. Here we use single-cell RNA sequencing, single-cell Tcra and Tcrb sequencing, and adoptive-transfer experiments to show that, unexpectedly, the splenic PPARglo Treg population is transcriptionally heterogeneous and engenders Tregs in multiple nonlymphoid tissues beyond visceral adipose tissue, e.g. skin and liver. The existence of a general pool of splenic precursors for nonlymphoid-tissue Tregs opens new possibilities for regulating their emergence experimentally or therapeutically.
