Chromatin accessibility analysis of CNS4-sufficient and defincient regulatory T cells, Treg cell precursors, and mature and semimature CD4 single positives

ABSTRACT: We have discovered that deletion of a conserved regulatory element upstream of the Foxp3 gene, termed CNS4, results in the abrogation of IL-2 mediated induction of Foxp3 expression during regulatory T cell development. However, the mice still harbor a reduced but functional population of Treg cells. To understand potential compensatory mechanisms driving the differentiation and expansion of regulatory T cells in the absence of CNS4, we profiled CNS4-deficient and -sufficient regulatory T cells, as well as related cell types, from the thymuses of male mice by ATAC-sequencing.

A distal Foxp3 enhancer enables interleukin-2 dependent thymic Treg cell lineage commitment for robust immune tolerance

Project description:STAT5 transcription factor activation downstream of the Interleukin-2 receptor (IL-2R) induces expression of Foxp3, a critical step in the differentiation of regulatory T (Treg) cells. Due to the pleiotropic outputs of IL-2R signaling, it is unclear whether STAT5 acts directly on the Foxp3 locus to promote its expression . Here, we report that IL-2 – STAT5 signaling converged on an enhancer (CNS4) during Foxp3 induction. CNS4 facilitated and sustained the IL-2 dependent CD25+Foxp3– precursor to Treg cell transition in the thymus. Its deficiency resulted in markedly impaired Treg cell generation in neonates, which was partially mitigated with age. While the thymic Treg cell paucity caused by CNS4 deficiency did not result in autoimmunity on its own, it exacerbated autoimmune manifestations caused by disruption of the Aire gene. Thus, CNS4 enhancer activity ensures robust Treg cell differentiation early in postnatal life and cooperatively with other tolerance mechanisms, minimizes autoimmunity.

Gene expression profiles of CD4SP Foxp3GFP-CD25+ Treg precursors and Foxp3GFP-CD25- thymocytes

Project description:We investigated at which stage of maturation commitment to a stable Foxp3-expressing phenotype takes place. We assessed stability of Foxp3 expression in thymic Foxp3+ Treg subsets of different maturity, defined by CD24 expression. Next we compared gene expression profiles of Foxp3+ Treg subsets (+) of different maturity (24lo, 24int, 24hi) and could identify a set of genes that were specifically up or downregulated in Foxp3+ Tregs, but not in Foxp3- conventional T cells, in a maturation-dependent manner. Gene expression of Foxp3+ Treg subsets (+) of different maturity (24lo, 24int, 24hi) compared to their Foxp3- conventional Tcell subsets (-) counterpart.

Human Treg LC-MSMS - Foxp3 drives oxidative phosphorylation and protection from lipotoxicity

Project description:Regulatory T cells (Treg) have been shown to adopt a catabolic metabolic programme with increased capacity for fatty acid oxidation fuelled oxidative phosphorylation (OXPHOS). The role of Foxp3 in this metabolic shift is poorly understood. Here we show that Foxp3 was sufficient to induce a significant increase in the spare respiratory capacity of the cell, the extra OXPHOS capacity available to a cell to meet increased demands on energy in response to work. Foxp3-expressing cells were enhanced in their ability to utilise palmitate for respiration and, in addition, the activity of electron transport complexes I, II and IV were enhanced following Foxp3 expression. Foxp3 also imparts a selective advantage in ATP generation capacity, one that might be exploited as a source of adenosine for functional immunomodulation. In order to explore possible mechanisms for these differences in metabolism we conducted a quantitative proteomics study to compare the contribution of TGFβ and the transcription factor Foxp3 to the Treg proteome. We used quantitative mass spectrometry to examine differences between proteomes of nuclear and cytoplasmic Foxp3-containing CD4+ T cells from various sources with Foxp3- activated CD4 T cells, as well as Treg from human peripheral blood. Gene set enrichment analysis of our proteomic datasets demonstrated that Foxp3 expression is associated with a significant up regulation of several members of the mitochondrial electron transport chain. Not only does Foxp3 influence genes directly concerned with immune function, but also with the energy generating functions of Treg.

Foxp3 ablation in peripheral mature regulatory T cells

Project description:Analysis of Foxp3 ablated peripheral regulatory T cells. Regulatory T cells require the expression of the transcription factor Foxp3 for thymic development. It is not known whether continuous expression of Foxp3 is required for the maintained function of mature regulatory T cells in the periphery. Results indicate changes to the regulatory T cell developmental program in the absence of Foxp3. Keywords: genetic modification
