REV-ERBα regulates regulatory T cell function in inflammatory bowel disease [CUT&RUN]

ABSTRACT: Colonic Rorgt+Foxp3+ Treg cells are critical to maintain intestinal homeostasis and prevent inflammatory bowel diseases by suppressing exuberant innate and adaptative immune responses. In this study, In this study, we found that REV-ERB was highly expressed in colonic RORt+Foxp3+ Treg cells and essential for their differentiation and function. Deletion of REV-ERB in Treg cells lead to diminished colonic RORt+Foxp3+ Treg cell populations even at steady state, and render mice more susceptible to TNBS and/or oxazolone-induced colitis. As a transcriptional repressor, REV-ERB can directly repress the expression of pro-inflammatory cytokines IL-17a and IL-17f, and promote RORt expression through Bhlhe40-c-maf axis in RORt+Foxp3+ Treg cells. Furthermore, REV-ERB also orchestrate RORt genome-wide distributions and co-regulate core signature genes in RORt+Foxp3+ Treg cells, including IL-10, CTLA-4, Icos, c-maf.

REV-ERBα regulates regulatory T cell function in inflammatory bowel disease [RNA-seq]

Project description:Colonic Rorgt+Foxp3+ Treg cells are critical to maintain intestinal homeostasis and prevent inflammatory bowel diseases by suppressing exuberant innate and adaptative immune responses. In this study, In this study, we found that REV-ERBa was highly expressed in colonic RORgt+Foxp3+ Treg cells and essential for their differentiation and function. Deletion of REV-ERB in Treg cells lead to diminished colonic RORgt+Foxp3+ Treg cell populations even at steady state, and render mice more susceptible to TNBS and/or oxazolone-induced colitis. As a transcriptional repressor, REV-ERBa can directly repress the expression of pro-inflammatory cytokines IL-17a and IL-17f, and promote RORgt expression through Bhlhe40-c-maf axis in RORgt+Foxp3+ Treg cells. Furthermore, REV-ERB also orchestrate RORgt genome-wide distributions and co-regulate core signature genes in RORgt+Foxp3+ Treg cells, including IL-10, CTLA-4, Icos, c-maf.

Discrete Functions of Rev-erba Couple Metabolism to the Clock [array]

Project description:Circadian and metabolic physiology are intricately intertwined, as illustrated by Rev-erb , a transcription factor (TF) that functions both as a core repressive component of the cell autonomous clock and as a regulator of metabolic genes. Here we show that Rev-erb modulates the clock and metabolism by different genomic mechanisms. Clock control requires Rev-erb to bind directly to the genome at its cognate sites, where it competes with activating ROR TFs. By contrast, Rev-erb regulates metabolic genes primarily by recruiting the HDAC3 corepressor to sites to which it is tethered by cell type-specific transcription factors. Thus, direct competition between Rev-erb and ROR TFs provides a universal mechanism for self-sustained control of molecular clock across all tissues, whereas Rev-erb utilizes lineage-determining factors to convey a tissue-specific epigenomic rhythm that regulates metabolism tailored to the specific need of that tissue.

The nuclear receptor REV-ERBa modulates Th17 cell differentiation and function by competing with RORgt

Project description:T helper 17 (Th17) cells produce interleukin-17 (IL-17) cytokines and drive inflammatory responses in autoimmune diseases such as multiple sclerosis and rheumatoid arthritis. The differentiation of Th17 cells is dependent on the retinoic acid receptor-related orphan nuclear receptor RORgt. Here we identify REV-ERBa (encoded by Nr1d1), a member of the nuclear hormone receptor family (NHR), as a transcriptional repressor that antagonizes RORgt function in Th17 cells. REV-ERBa binds to ROR response elements (RORE) in Th17 cells and inhibits the expression of RORgt-dependent genes such as Il17a and Il17f. Furthermore, elevated REV-ERBa expression or treatment with a synthetic REV-ERB agonist significantly delays the onset and impedes the progression of experimental autoimmune encephalomyelitis (EAE), a Th17 cell-mediated autoimmune disease. These results suggest that modulating REV-ERB activity may hold therapeutic potential for treatment of Th17 cell-mediated autoimmune diseases.

c-Maf-dependent Treg cell control of intestinal TH17 cells and IgA establishes host–microbiota homeostasis

Project description:Foxp3+ regulatory T (Treg) cells are essential for immunological tolerance and homeostasis. In peripheral tissues, Treg cells acquire enhanced suppressive functions and co-opt distinct transcriptional modules, allowing context and tissue-dependent immune regulation. Here we show that the transcription factor c-Maf was highly expressed by effector Treg cells and controlled their IL-10 production. In the intestine, c-Maf was required for the differentiation of RORgt+ microbiota-dependent Treg cells, and restricted their production of inflammatory cytokines. Consequently, Treg cell-specific loss of c-Maf resulted in perturbed intestinal homeostasis, microbial dysbiosis and a selective failure to control Th17 responses during homeostasis and upon chemically induced epithelial damage. Molecular profiling revealed that c-Maf regulated expression of key genes of the transcriptional signature of intestinal Treg cells, including Rorc and Il10. Thus, our study identifies a key role of c-Maf in preserving the identity and function of intestinal Treg cells, essential for the control of intestinal immune homeostasis.

Project description:We report the genomic regions enriched for Rev-erb(beta) binding in WT mouse liver, in addition to the false positive regions enriched by ChIP for Rev-erb(alpha) in Rev-erb(alpha) KO liver. In conjunction with previously published data for Rev-erb(alpha) in GSE26345 (GSM647029, GSM647033, and GSM647034), we report the common and subtype specific cistromes for Rev-erb using a quantitative analysis method.

Ndfip1 restricts mTORC1 signalling and glycolysis in regulatory T cells to prevent autoinflammatory disease

Project description:Project abstract: Foxp3+ T regulatory (Treg) cells have important functions in suppressing immune cell activation and establishing normal immune homeostasis. How Treg cells maintain their identity is not completely understood. Here we show that Ndfip1, a co-activator of Nedd4-family E3 ubiquitin ligases, is required for Treg cell stability and function. Ndfip1 deletion in Treg cells disrupts immune homeostasis and results in autoinflammatory disease. Ndfip1-deficient Treg cells are highly proliferative and are more likely to lose Foxp3 expression to become IL-4-producing TH2 effector cells. Proteomic analyses indicate that Ndfip1 deficiency alters the metabolic signature of Treg cells. Metabolic profiling reveals elevated glycolysis and increased mTORC1 signalling. Additional data suggest that Ndfip1 restricts Treg cell metabolic capacity and IL-4 production via distinct mechanisms. Thus, Ndfip1 preserves Treg lineage stability by preventing the expansion of highly proliferative and metabolically active cells that can cause immunopathology via secretion of IL-4.
