Abstract
Human memory T cells (MTC) are poised to rapidly respond to antigen re-exposure. Here, we derived the transcriptional and epigenetic programs of resting and ex vivo activated, circulating CD4+ and CD8+ MTC subsets. A progressive gradient of gene expression from naïve to TCM to TEM is observed, which is accompanied by corresponding changes in chromatin accessibility. Transcriptional changes suggest adaptations of metabolism that are reflected in altered metabolic capacity. Other differences involve regulatory modalities comprised of discrete accessible chromatin patterns, transcription factor binding motif enrichment, and evidence of epigenetic priming. Basic-helix-loop-helix factor motifs for AHR and HIF1A distinguish subsets and predict transcription networks to sense environmental changes. Following stimulation, primed accessible chromatin correlate with an augmentation of MTC gene expression as well as effector transcription factor gene expression. These results identify coordinated epigenetic remodeling, metabolic, and transcriptional changes that enable MTC subsets to ultimately respond to antigen re-encounters more efficiently.

Abstract
Ulcerative Colitis (UC) is a chronic disease, in the progression of which an immune overreaction may play an important role. IL-22 is a member of the IL-10 superfamily of cytokines and is pleiotropic in immune regulation and inflammatory responses. IL-22 can produce protective effects, promote wound healing and tissue regeneration, while it can also induce inflammatory reactions when it is chronically overexpressed. Extensive literatures reported that IL-22 played an essential role in the pathogenic development of UC. IL-22 participates in the whole disease process of UC involving signaling pathways, gene expression regulation, and intestinal flora imbalance, making IL-22 a possible candidate for the treatment of UC. In this paper, the latest knowledge to further elucidate the role of IL-22 in UC was summarized and analyzed.

Abstract
IL-22 plays a crucial role in promoting inflammation, antimicrobial immunity and tissue repair at barrier surfaces. The role of IL-22 in colitis is still controversial: while IL-22 has a protective effect on gut epithelium in acute injuries, it also enhances colitis in a context-dependent manner. Here, we summarize the Yin and Yang of IL-22 in colitis. Particularly, we emphasize the role of innate lymphoid cells (ILCs) in IL-22 production and regulation. A previously underappreciated transcription factor, Musculin (MSC), has been recently identified to be expressed in not only Th17 cells, but also RORγt+/Id2+ IL-22-producing group 3 ILCs in the gut of naïve mice. We hypothesize that the co-expression and interaction of MSC with the key transcription repressor Id2 in developing lymphoid cells (e.g., in LTi cells) and ILC precursors might fine tune the developmental programs or regulate the plasticity of adaptive Th subset and innate ILCs. The much-elevated expression of IL-22 in MSC-/- ILC3s suggests that MSC may function as: 1) a transcription suppressor for cytokines, particularly for IL-22, and/or 2) a gatekeeper for specific lineages of Th cells and innate ILCs as well. Amelioration of colitis symptoms in MSC-/- mice by IL-22-blocking agent IL-22BP-Fc suggests a counterintuitive pathogenic role of IL-22 in the absence of MSC as a checkpoint. The theory that exuberant production of IL-22 under pathological conditions (e.g., in human inflammatory bowel disease, IBD) may cause epithelial inflammation due to endoplasmic reticulum (ER) stress response is worth further investigation. Rheostatic regulation of IL-22 may be of therapeutic value to restore homeostatic balance and promote intestinal health in human colitis.

Abstract
Intestinal inflammatory reactions and resulting tissue injuries are two major aspects of inflammatory bowel disease (IBD). The regulatory factors involved in the pathogenesis of IBD remain unclear. Recent studies showed that musculin (MSC) as a transcription suppressor participates in the regulation of certain immune functions. The purpose of this study was to determine the impact of MSC deficiency on colonic injury and inflammatory reaction under IBD, where wild-type (WT, +/+) and MSC-knockout (MSCKO, MSC-/-) mice were induced for disease by dextran sulfate sodium (DSS) in drinking water. Immunohistochemistry hematoxylin-eosin (H&E) staining, enzyme-linked immunosorbent assay (ELISA), and quantitative real-time polymerase chain reaction (qRT-PCR) were used to analyze the matching samples from groups of different genotypes. The colonic epithelial injury in the MSC-/- IBD group was much severer than that in the +/+ IBD group, concurrent with higher IL-22 levels from the supernatant of ex vivo cultured colon tissues in the MSC-/- IBD group than those in the +/+ IBD group. The mRNA levels of IL-22 in mesenteric lymph nodes (MLN) also manifested similar tendency. MSC deficiency may enhance the inflammatory reactions in the gut via excessive secretion of IL-22, leading to aggravated colonic epithelial injury under IBD.

Abstract
Transcription suppressor Musculin (MSC) is enriched in pro-inflammatory Th17 and IL-22-producing ILC3s. While MSC+/+ mice survived DSS-induced colitis, MSC-/- mice showed elevated pro-inflammatory cytokines with severer pathology, reduced body weight, and earlier death. Reversal of colitis symptoms in MSC-/- mice by IL-22 antagonism suggests the existence of MSC:IL-22 regulatory axis.

Abstract
We recently demonstrated that human T-helper (Th) 17 cells, unlike Th1 cells, do not proliferate in response to T-cell receptor stimulation, mainly because of their reduced capacity to produce and respond to IL-2. In this study, we show that their lower responsiveness to IL-2 is due to the selective expression of Musculin (MSC), a member of the basic helix-loop-helix transcription factors. We show that MSC expression in human Th17 cells is retinoic acid orphan receptor (ROR)γt-dependent, and allows the upregulation of PPP2R2B, a regulatory member of the protein phosphatase 2A (PP2A) enzyme. High PPP2R2B levels in human Th17 cells were responsible for the reduced STAT5B Ser-193 phosphorylation upon IL-2 signalling and, therefore, impaired STAT5B DNA binding and transcriptional activity on IL-2 target genes. PP2A, observed in Th17 cells, controls also STAT3, dephosphorylating Ser727, thus increasing its activity that plays a crucial role in Th17 development and/or maintenance. Thus, our findings identify an additional mechanism responsible for the limited expansion of human Th17 cells, and could provide a further explanation for the rarity of these cells in inflamed tissues.

The transcription factor musculin promotes the unidirectional development of peripheral T reg cells by suppressing the T H2 transcriptional program. Nat Immunol 2017; 18:344-353.

Abstract
Although master transcription factors (TFs) are key to the development of specific T cell subsets, whether additional transcriptional regulators are induced by the same stimuli that dominantly repress the development of other, non-specific T cell lineages has not been fully elucidated. Through the use of regulatory T cells (Treg cells) induced by transforming growth factor-β (TGF-β), we identified the TF musculin (MSC) as being critical for the development of induced Treg cells (iTreg cells) by repression of the T helper type 2 (TH2) transcriptional program. Loss of MSC reduced expression of the Treg cell master TF Foxp3 and induced TH2 differentiation even under iTreg-cell-differentiation conditions. MSC interrupted binding of the TF GATA-3 to the locus encoding TH2-cell-related cytokines and diminished intrachromosomal interactions within that locus. MSC-deficient (Msc-/-) iTreg cells were unable to suppress TH2 responses, and Msc-/- mice spontaneously developed gut and lung inflammation with age. MSC therefore enforced Foxp3 expression and promoted the unidirectional induction of iTreg cells by repressing the TH2 developmental program.
