The TNF family member TL1A induces IL-22 secretion in committed human TH17 cells via IL-9 induction

ABSTRACT: TL1A contributes to the pathogenesis of several chronic inflammatory diseases, including Inflammatory Bowel Diseases by enhancing TH1, TH17, and TH2 responses. TL1A mediates a strong co-stimulation of these TH subsets particularly of mucosal CCR9+ T cells. However, the signaling pathways that TL1A induces in different TH subsets are incompletely understood. Here, we investigated the function of TL1A on human TH17 cells. TL1A together with TGF- IL-6, and IL-23 enhanced the secretion of IL-17 and IFN- from human CD4+ memory T cells. TL1A induced the expression of the transcription factors BATF and T-bet that correlated with the secretion of IL-17 and IFN-. In contrast, TL1A alone induced high levels of IL-22 in memory CD4+ T cells and committed TH17 cells. However, TL1A did not enhance expression of IL-17A in TH17 cells. Expression of the transcription factor aryl hydrocarbon receptor that regulates expression of IL-22 was not affected by TL1A. We performed transcriptome analysis of TH17 cells to determine genes that are transcriptionally regulated by TL1A. transcriptome analysis revealed increased expression of IL-9 in response to TL1A.

Mouse Th17 T cells, IL-23 stimulated

Project description:Interleukin 23 (IL-23) triggers pathogenic features in pro-inflammatory, IL-17-secreting T cells (Th17 and Tγδ17) that play a key role in the development of inflammatory diseases. However, the IL-23 signaling cascade remains largely undefined. Here we used quantitative phosphoproteomics to characterize IL-23 signaling in primary murine Th17 cells. We quantified 6,888 phosphorylation sites in Th17 cells, and found 168 phosphorylations regulated upom IL-23 stimulation. IL-23 increased the phosphorylation of the myosin regulatory light chain (RLC), an actomyosin contractibility marker, in Th17 and Tγδ cells. IL-23-induced RLC phosphorylation required JAK2 and ROCK catalytic activity, and the study of the IL-23/ROCK axis revealed an unexpected role of IL-23 in the migration of Tγδ17 and Th17 cells. Moreover, pharmacological inhibition of ROCK reduced Tγδ17 recruitment to inflamed skin upon challenge with inflammatory agent Imiquimod. This work: i) provides new insights into phosphorylation networks that control Th17 cells, ii) widely expands the current knowledge on IL-23 signaling, and iii) contributes to the increasing list of immune cells subsets characterized by global phosphoproteomic approaches.

TL1A is a central regulator of group 3 innate lymphoid cell function in colitis

Project description:Inflammatory bowel disease (IBD) results from a dysregulated interaction between the microbiota and a genetically susceptible host. Genetic studies have linked TNFSF15 polymorphisms and its protein TNF-like ligand 1A (TL1A) with IBD, but the functional role of TL1A in linking tissue homeostasis and intestinal inflammation is not known. Here, using cell-specific genetic deletion models, we report an essential role for CX3CR1+ mononuclear phagocyte (MNP)-derived TL1A, which is induced by adherent IBD-associated microbiota, in regulating group 3 innate lymphoid cell (ILC3) production of IL-22 and mucosal healing in acute colitis. However, in contrast to this protective role in acute colitis, TL1A-dependent expression of OX40L in MHCII+ ILC3 during colitis leads to co-stimulation of antigen-specific T cells and is required for chronic T cell colitis. These results identify a new role for ILC3 in regulating intestinal T cells and reveal a central role for TL1A in regulating ILC3 barrier immunity during colitis.

G-Protein-Coupled Receptor 68 Negatively Regulates IL-22 Production in Human Th17 Cells

Project description:Purpose: To identify novel genes regulated by the aryl hydrocarbon receptor that influence human Th17 cell function. Methods: Naïve CD4 T cells from peripheral blood of six healthy human volunteers were cultured under four experimental conditions for three days: anti-CD3 and anti-CD28 antibodies (Media control), Media with Th17 conditions (IL-6, TGF-b, IL-1b, IL-23), Th17+FICZ and Th17+CH223191. Total RNA was extracted from each sample on day 3 and sequenced in a paired-end 2x50bp strategy on an Illumina HiSeq1500. A total of six donors were analyzed. Results: AhR activation with FICZ suppressed IL-17 production from human CD4 T cells and increased IL-22. AhR inhibition with CH223191 potently suppressed IL-22 and modestly increased IL-17 production. On day 3, the number of significantly regulated genes for each treatment were 975 (Th17), 88 (Th17+FICZ) and 142 (Th17+CH223191). 11 common genes were significantly regulated by all three treatments. One of these, GPR68, was investigated further in functional studies since its expression correlated with IL-22 production. Activation of GPR68 with a positive allosteric modulator suppressed IL-22 concentrations in human Th17 cell cultures. Conclusions: Our study demonstrates that GPR68 activation can negatively regulate IL-22 production from human CD4 T cells in the presence of an AhR agonist. RNA-seq is a powerful method to identify novel gene targets that regulate cytokines involved in chronic inflammatory diseases.

Gene expression profile of human epidermal keratinocytes in response to IFNgamma, IL-4, IL-6, IL-17A and IL-22

Gene expression profile of human epidermal keratinocytes in response to IFNgamma, IL-4, IL-6, IL-17A and IL-22

Project description:To understand the role of epidermal keratinocytes in immunopathology of skin diseases with predominant T helper (Th) cell responses, we measured the genome-wide transcriptional profile of human keratinocytes in response to IFNgamma, IL-4, IL-17A or IL-22, major cytokines produced by Th1, Th2, Th17 or Th22 cells, respectively. IL-6 was also included in the transcriptional profile analysis because a variety of pro-inflammatory stimuli stimulate human keratinocytes to produce IL-6 that has an autocrine or paracrine role in epidermal immunity. We aimed to discover commonly expressed genes in human keratinocytes in response to pro-inflammatory cytokines, which would be associated with common pathophysiological responses in various skin diseases such as skin permeability barrier disruption or epidermal hyperplasia. Normal human keratinocytes (NHKs) were stimulated with IFNγ, IL-4, IL-6, IL-17A and IL-22 for 24 hours and harvested for total RNA extraction and hybridization on Affymetrix microarrays.

Th22 cells represent a distinct human T cell subset involved in epidermal immunity and remodeling

Project description:Th subsets are defined according to their production of lineage-indicating cytokines and functions. In this study, we have identified a subset of human Th cells that infiltrates the epidermis in individuals with inflammatory skin disorders and is characterized by the secretion of IL-22 and TNF-a, but not IFN-g, IL-4, or IL-17. In analogy to the Th17 subset, cells with this cytokine profile have been named the Th22 subset. Th22 clones derived from patients with psoriasis were stable in culture and exhibited a transcriptome profile clearly separate from those of Th1, Th2, and Th17 cells; it included genes encoding proteins involved in tissue remodeling, such as FGFs, and chemokines involved in angiogenesis and fibrosis. Primary human keratinocytes exposed to Th22 supernatants expressed a transcriptome response profile that included genes involved in innate immune pathways and the induction and modulation of adaptive immunity. These proinflammatory Th22 responses were synergistically dependent on IL-22 and TNF-a. Furthermore, Th22 supernatants enhanced wound healing in an in vitro injury model, which was exclusively dependent on IL-22. In conclusion, the human Th22 subset may represent a separate T cell subset with a distinct identity with respect to gene expression and function, present within the epidermal layer in inflammatory skin diseases. Future strategies directed against the Th22 subset may be of value in chronic inflammatory skin disorders.

IL-22-dependent dysbiosis and mononuclear phagocyte depletion contribute to steroid-resistant gut graft-versus-host disease in mice I

Project description:CD4+ and CD8+ T cells can reciprocally differentiate into Th/Tc1, Th/Tc17 and Th/Tc22. Although alloreactive Th/Tc1 cells play a critical role in initiating pathogenesis of gut acute graft-versus-host disease (Gut-aGVHD), the pathogenic T cells in steroid-resistant Gut-aGVHD (SR-Gut-aGVHD) remains unclear. Here, we show that in murine models of SR-Gut-aGVHD, the pathogenesis is associated with reduction of IFN-g+ Th/Tc1 and IL-17A+IL-22- Th/Tc17 but expansion of IL-17-IL-22+ Th/Tc22, particularly Tc22 cells. IL-22 from Th/Tc22 cells causes dysbiosis. Using a Gut-aGVHD model induced by alloreactive IFN-g-/- CD8+ T cells, we show that the Gut-aGVHD pathogenesis requires both dysbiosis and depletion of CX3CR1hi mononuclear phagocytes (MNP) that regulate intestinal bacterial translocation. Absence of IFN-g leads to preferential expansion of Tc22 that induce dysbiosis by augmenting RegIIIg production, and depletion of CX3CR1hi MNP via its PD-1 interaction with tissue PD-L1. Interestingly, SR-Gut-aGVHD is also associated with depletion of CX3CR1hi MNP that reduces expansion of Tc22 under steroid treatment. Our studies indicate that expansion of Th/Tc22, dysbiosis, and depletion of CX3CR1hi MNP cells play critical roles in SR-Gut-aGVHD pathogenesis. These results provide new avenue towards studies in patients and call for caution in clinical testing of IL-22 agonists or IFN-g antagonist in patients.

Tsirvouli2021 - Cytokine and eicosanoid signaling in psoriatic keratinocytes

Project description:The psoKC (psoriatic keratinocyte) model is represnting the behavour of keratinocytes in the later or chronic stage of psoriasis in response to the main cytokines that constitute the characteristic cytokine milieu, namely IFNg and TNFa (mainly derived by Th1 cells), and IL-17 and IL-22 (mainly derived by Th17 cells). Additionally, the model explores the role of exogenous PGE2 through the activation of EP4 receptor signaling. The response to the aforementioned stimuli was not only limited to the cell fate decisions of keratinocytes (proliferation, apoptosis or differentiation) but also include their effect on the psoriatic environment with respect to the secretion of ligands and intercellular-acting stimuli.
