RNA-seq of Treg and Tconv subsets from murine spleen

ABSTRACT: While unique subsets of Treg cells have been described in some non-lymphoid tissues, their relationship to Treg cells in secondary lymphoid organs and circulation remains unclear. We have identified a recirculating and highly suppressive effector Treg cell subset that expresses the α2 integrin, CD49b, and exhibits a unique tissue distribution. To identify genes and pathways enriched in CD49b+ Treg cells, we performed RNA-seq of splenic CD49b+ and CD49b− Treg cells that were of otherwise similar activation status based on expression of CD44 and CD62L. This revealed that splenic CD49b+ Treg cells express genes related to migration and activation, but are relatively depleted of genes whose expression is TCR-dependent in Treg cells. These results shed light on the identity and development of a functionally potent subset of mature effector Treg cells that recirculates through and surveys peripheral tissues.

TCR sequencing of Treg and Tconv subsets from murine spleen

Project description:While unique subsets of Treg cells have been described in some non-lymphoid tissues, their relationship to Treg cells in secondary lymphoid organs and circulation remains unclear. We have identified a recirculating and highly suppressive effector Treg cell subset that expresses the α2 integrin, CD49b, and exhibits a unique tissue distribution. We used TCR sequencing to ask whether CD49b+ activated Treg cells and CD49b− activated Treg cells represent stable states of Treg cell differentiation instructed by distinct TCR repertoires. We did not find a pattern of clonotypes that was specific to either subset, suggesting that essentially all CD49b− Treg cells could give rise to CD49b+ cells. These results shed light on the identity and development of a functionally potent subset of mature effector Treg cells that recirculate through and survey peripheral tissues.

Single-cell RNA-seq of splenic Treg and Tconv cells

Project description:While unique subsets of Treg cells have been described in some non-lymphoid tissues, their relationship to Treg cells in secondary lymphoid organs and circulation remains unclear. We have identified a short-lived effector Treg cell subset that expresses the α2 integrin, CD49b, and exhibits a unique tissue distribution. Projection of the CD49b+ Treg signature onto the Treg phenotypic landscape as inferred by single-cell RNA-seq analysis, placed these cells at the apex of the Treg developmental trajectory. These results shed light on the identity and development of a functionally potent subset of mature effector Treg cells that recirculate through and survey peripheral tissues.

Treg cells from human blood differentiate into non-lymphoid tissue-resident effector cells upon TNFR2 costimulation

Project description:Regulatory T (Treg) cells can facilitate transplant tolerance and attenuate autoimmune- and inflammatory diseases. Therefore, it is clinically relevant to stimulate Treg cell expansion and function in vivo and to create therapeutic Treg cell products in vitro. We report that TNF receptor 2 (TNFR2) is a unique costimulus for naïve, thymus-derived (t)Treg cells from human blood that promotes their differentiation into non-lymphoid tissue (NLT)-resident effector Treg cells, without Th-like polarization. In contrast, CD28 costimulation maintains a lymphoid tissue (LT)-resident Treg cell phenotype. We base this conclusion on transcriptome and proteome analysis of TNFR2- and CD28-costimulated CD4+ Treg cells and conventional T (Tconv) cells, followed by bioinformatic comparison with published transcriptomic Treg cell signatures from NLT and LT in health and disease, including autoimmunity and cancer. These analyses illuminate that TNFR2 costimulation promotes Treg cell capacity for survival, migration, immunosuppression and tissue regeneration. Functional studies confirmed improved migratory ability of TNFR2-costimulated tTreg cells. Flow cytometry validated the presence of the TNFR2-driven Treg cell signature in effector/memory Treg cells from the human placenta as opposed to blood. Thus, TNFR2 can be exploited as driver of NLT-resident Treg cell differentiation for adoptive cell therapy or antibody-based immunomodulation in human disease.

Transcriptional profiling of Regulatory T (Treg) cells and CD4+ conventional T (Tconv) cells from vTreg53 TCR transgenic and PPARg reporter mice

Project description:We reported transcriptional characterization of Treg and Tconv cells from thymic, splenic, and visceral adipose tissue (VAT) of vTreg53 TCR transgenic mice and control littermates. We examined the effect of Foxp3 on splenic and VAT CD4+ T cell transcriptome. We profiled gene expression in a novel PPARg+ splenic Treg population. We uncovered that the characteristic phenotype of VAT Treg cells was acquired in two stages.

Non-classical CD4+CD49b+ regulatory T cells as a better alternative to conventional CD4+CD25+ T cells to dampen arthritis severity

Project description:Regulatory T (Treg) cells actively control pathological immune responses and immunotherapeutic strategies triggering an increase in the number and/or the function of endogenous Treg cells emerge as a promising therapeutic strategy in autoimmune diseases to restore tolerance. A remarkable heterogeneity in peripheral Treg cells has been evidenced and underscored the need to better characterize them and compare their suppressive function to determine which Treg subset will be optimally suitable for a given clinical situation. We demonstrated that repetitive injections of immature dendritic cells (DC) expand FoxP3-negative CD49b+ Treg cells that display an effector memory phenotype. Transcriptome analysis of ex-vivo isolated Treg-expanded by DC injections contains multiple transcripts of the canonical Treg signature shared mainly by CD25+ but also by other Treg subphenotypes. We provided an in-depth characterization of the CD49b+ Treg cells phenotype underscoring their similarities with CD25+ Treg cells and highlighting some specific expression pattern for several markers including LAG3, KLRG1, CD103, ICOS, CTLA-4 and GZB. Comparison of their suppressive mechanism in vitro and in vivo with that of FoxP3-positive Treg cells provide evidence of their potent suppressive activity in vivo, partly dependent on IL-10 secretion. Altogether our results underscore the therapeutic potential of IL-10 secreting CD49b+ Treg cells in arthritis and strongly suggest that expression of several canonical markers and suppressive function could be FoxP3-independent All gene expression profiles were obtained from highly purified T cell populations sorted by flow cytometry. To reduce variability, cells from multiple mice were pooled for sorting, and two to three replicates were generated for all groups. RNA from 2.5-10 x 105 cells was amplified, labeled, and hybridized to Affymetrix M430v2 microarrays.

Bulk RNA-seq of OX40 wt and KO spleen Treg and Tconv

Project description:Regulatory T cells (Tregs) are essential for limiting adaptive immunity, and restrain type-2 inflammation in allergic disease. As Tregs function locally, the mechanisms that coordinate their suppressive role in the inflamed niche are of great interest. Here we show that group 2 innate lymphoid cells (ILC2) are critical mediators of IL-33-driven Treg expansion in allergic inflammation. ILC2-derived OX40L promotes the local expansion of Gata3high Tregs, which possess distinct transcriptional and functional programmes that enforce co-localisation with ILC2 in the inflamed airways. Using OX40 Treg-conditional mutant mice, we show that Gata3high Tregs are important for restraining adaptive type-2 immunity. Mechanistically, Gata3high Tregs modulate OX40L bioavailability on ILC2, which controls effector memory Th2 cell formation. As such, ILC2 can simultaneously engage both the effector and regulatory arms of adaptive type-2 immunity via the OX40L-OX40 signalling axis. More specifically, ILC2-Treg interactions serve as a critical feedback mechanism to control adaptive type-2 immunity.

Lack of phosphatidylinositol 3-kinase VPS34 in regulatory T cells leads to a fatal lymphoproliferative disorder without affecting their development

Project description:Regulatory T (Treg) cells are essential for the maintenance of immunological tolerance, yet the molecular components required for their maintenance and effector functions remain incompletely defined. Inactivation of VPS34 in Treg cells led to an early, lethal phenotype, with massive effector T cell activation and inflammation, like mice lacking Treg cells completely. However, VPS34-deficient Treg cells developed normally, populated the peripheral lymphoid organs and effectively supressed conventional T cells in vitro. Our data suggest that VPS34 is required for the maturation of Treg cells or that mature Treg cells depend on VPS34 for survival. Functionally, we observed that lack of VPS34 activity impairs cargo processing upon transendocytosis, that defective autophagy contributes to, but is not sufficient to explain this lethal phenotype, and that loss of VPS34 activity induces a state of heightened metabolic activity that may interfere with metabolic networks required for maintenance or suppressive functions of Treg cells.

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

Project description: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.
