RNA-seq of bulk Treg and Tconv cells from murine liver and lymphoid tissues

ABSTRACT: With the aim of understanding how Treg cells in highly vascularized tissues are related to Treg cells in other organs, we performed RNA-seq analysis of bulk Treg and Tconv cells isolated from liver, blood, spleen, and the liver-draining portal lymph node. This revealed a clear separation of cell transcriptomes by both tissue and Treg/Tconv identity, with cells from the liver falling between blood- and spleen-derived cells. Compared to splenic Treg cells, hepatic Treg cells were enriched for genes related to proliferation and activation, and genes encoding chemokine and cytokine receptors.

miRNA expression in CD4+CD25- conventional (Tconv) and CD4+CD25+ regulatory T (Treg) cells

Project description:miRNA expression profiling in highly purified murine CD4+ Tconv and Treg cells. FoxP3-GFP-hCre1a(high) reporter mice were used to separate both populations based on surface markers and presence or absence of GFP. Two-condition experiment, Tconv vs. Treg. Biological replicates: 1 Tconv, 1 Treg, purified from the same pooled mice. One replicate on 1 array.

Human IFNG+/- Treg and Tconv transcriptome

Project description:Microarray used to detail the global gene transcription underlying sorted IFNg+ and IFNg- Tregs (CD4+CD25+CD127lo) and Tconv (CD4+CD25-CD127+) for fresh (unexpanded) and 14 day expanded cells from human blood. Treg and Tconv were FACS isolated from five healthy subjects (median age of 26, range 22-30). Sorted cells were separated into two groups: the first group was stimulated for 4 hours with PMA/ionomycin and labeled with the IFNg cytokine capture kit (Miltenyi Biotech) followed by FACS isolation of IFNg- and IFNg+ populations. The second set was expanded to day 14 prior to reactivation and cytokine cell capture. For each IFNg sorted population, cells were pelleted and flash frozen before RNA isolation and processing.

Gene expression profiles of human Treg and Tconv cells induced by signals of pseudostarvation

Project description:We have employed whole genome microarray expression profiling of human Treg and Tconv cells as a discovery platform to identify genes differentially expressed upon signal of pseudostarvation (either mTOR inhibition or leptin neutralizaion) responsible for proliferation of Treg cell on one side and inhibition of Tconv cells on the other. Human Treg and Tconv cells isolated from healthy donors were pretreated or not with rapamycin or leptin mAb and stimulated with anti-CD3 and anti-CD28 beads for 12h.

Role of interleukin 2 on gene expression in lymph node Foxp3+CD4+ regulatory (Treg) and conventional T (Tconv) cells

Project description:Interleukine 2 (IL-2) is still one of the most interesting cytokines in T cell biology with its ability to control immune homeostasis by maintaining the functional identity of Foxp3+ regulatory T (Treg) cells and the expansion of activated conventional T (Tconv) cells. Yet, how IL-2 exactly enables Treg cells to suppress autoreactive Tconv cells and to maintain their identity is unclear. Using a mouse model in which IL-2 signaling via its high affinity receptor CD25 is selectively impaired, the “Il2ramut/mut” mouse, we report that Treg cells that only receive low IL-2 signals keep Il2ramut/mut but not WT Tconv cells “in check”, suggesting equal IL-2 signals in Treg and Tconv cells is essential to safeguard immune homeostasis. Furthermore, the comparative analysis of gene expression and epigenetic landscape of Il2ramut/mut and WT Treg cells support a model in which IL-2 "locks in” Treg cell identity and functions in vivo by controlling their genome-wide chromatin accessibility.

Tconv and Treg gene expression and repertoire analysis of ZAC mice

Project description:Autoimmune diseases, such as rheumatoid arthritis (RA), are believed to be caused, in part, by a defect in the selection of T cells. Developing T cells undergo a process known as “negative selection” where self-derived proteins are presented to the cells; those that react to the self-peptides are either eliminated, or develop into regulatory T cells (Tregs), which suppress immune responses by conventional T cells (Tconvs). In order to study self-reactive T cell receptors (TCRs), and their likely target antigens, we performed single cell repertoire analysis in ZAC mice with impaired TCR signaling. We sequenced TCR and transcriptomes of Treg and Tconv single cells from arthritic ZAC mice spleen (n=2). We discovered a cluster of pro-inflammatory Th17 Tconv cells in ZAC spleens that was absent in WT mice. ZAC Th17 TCRs showed clonal expansion. Different mice had different TCR sequences, which is expected.

Proteomics reveals unique identities of human TGF-β-induced and thymus-derived CD4+ regulatory T cells

Project description:The CD4+ regulatory T (Treg) cell lineage comprises thymus-derived (t)Treg cells and peripherally induced (p)Treg cells. As a model for Treg cells, studies employ TGF-β-induced (i)Treg cells generated from CD4+ conventional T (Tconv) cells in vitro. Here, we describe the relationship of iTreg cells to tTreg and Tconv cells. Proteomic analysis revealed that iTreg, tTreg and Tconv cell populations each have a unique protein expression pattern. iTreg cells had very limited overlap in protein expression with tTreg cells, regardless of cell activation status and instead shared signaling and metabolic proteins with Tconv cells. tTreg cells had a uniquely modest response to CD3/CD28-mediated stimulation. As a benchmark, we used a previously defined proteomic signature that sets ex vivo naïve and effector phenotype Treg cells apart from Tconv cells and includes unique Treg cell properties (Cuadrado et al., Immunity, 2018). This Treg cell core signature was largely absent in iTreg cells. We also used a proteomic signature that distinguishes ex vivo effector Treg cells from Tconv cells and naïve Treg cells. This effector Treg cell signature was partially present in iTreg cells. In conclusion, iTreg cells are distinct from tTreg cells and share limited features with ex vivo Treg cells at the proteomic level.
