Interaction between oncogenic FREM2 with IL-1β signaling contributes to esophageal squamous cell carcinoma progression

ABSTRACT: Inflammatory signals can promote tumorigenesis. The pro-inflammatory cytokine interleukin (IL)-1β is overexpressed in many types of tumor; however, it is unclear whether it directly interacted with oncogenes in esophageal squamous cell carcinoma. In this study, we performed RNA sequencing to identify tumorgenesis and recurrence-related factors in ESCC and identified FRAS1-related extracellular matrix protein (FREM)2 as a candidate oncogene. IL-1β and IL-1R1 were upregulated in ESCC tissue, which was accompanied by elevated Frem2 expression. FREM2 formed complex with IL-1R1 at the cell surface and promoted ESCC cell proliferation and migration via activation of nuclear factor-κB–p65/mitogen-activated protein kinase–c-Jun N-terminal kinase signaling. IL-1β stimulation resulted in the upregulation of FREM2 in ESCC cells through inhibition of Forkhead box P1. Increased FREM2 and IL-1R1 levels were correlated with shorter survival time in ESCC patients.

Gene regulation by IL-1β in IL-1R1-deficient mixed glia

Project description:Interleukin-1 (IL-1) is a key pro-inflammatory cytokine, which has diverse actions in the brain as a regulator of host defence responses and a mediator of inflammation. Two major agonists, IL-1α and IL-1β bind to a single known functional (type-1) IL-1 receptor (IL-1RI), which associates with an accessory protein (IL-1RAcP) leading to signal transduction. However, recent evidence suggests that some actions of IL-1 in the brain may be independent of IL-1R1 and its classical signalling pathways, pointing to an as yet unidentified functional receptor for IL-1 expressed in the CNS. In this study, cDNA array based gene expression profiling was used to identify possible genes induced by IL-1β independently of IL-1R1. The results show that IL-1β may indeed regulate some genes independently of IL-1R1, suggesting the presence of additional functional IL-1 receptors in the mouse brain.

IL-1β promotes MPN disease initiation by favoring early clonal expansion of JAK2-mutant hematopoietic stem cells

Project description:JAK2-V617F is the most frequent somatic mutation causing myeloproliferative neoplasm (MPN). JAK2-V617F can be found in healthy individuals with clonal hematopoiesis of indeterminate potential (CHIP) with a frequency much higher than the prevalence of MPN. The factors controlling the conversion of JAK2-V617F CHIP to MPN are largely unknown. We hypothesized that IL-1β mediated inflammation can favor this progression. We established an experimental system using bone marrow (BM) transplantations from JAK2-V617F and GFP transgenic (VF;GFP) mice, that were further crossed with IL-1β-/- or IL-1R1-/- mice. To study the role of IL-1β and its receptor on monoclonal evolution of MPN, we performed competitive BM transplantations at high dilutions with only 1-3 hematopoietic stem cells (HSCs) per recipient. Loss of IL-1β in JAK2-mutant HSCs reduced engraftment, restricted clonal expansion, lowered the total numbers of functional HSCs, and decreased the rate of conversion to MPN. Loss of IL-1R1 in the recipients also lowered the conversion to MPN, but did not reduce the frequency of engraftment of JAK2-mutant HSCs. WT recipients transplanted with VF;GFP BM that developed MPN had elevated IL-1β levels and reduced frequencies of mesenchymal stromal cells (MSCs). Interestingly, frequencies of MSCs were also reduced in recipients that did not develop MPN, had only marginally elevated IL-1β levels and displayed low GFP-chimerism resembling CHIP. Anti-IL-1β antibody preserved high frequencies of MSCs in VF;GFP recipients and reduced the rate of engraftment and the conversion to MPN. Our results identify IL-1β as a potential therapeutic target for preventing the transition from JAK2-V617F CHIP to MPN.

Noncanonical Il-1β maturation in microglia impairs cognition in chronic kidney disease via neuronal IL1R signaling

Project description:While cognitive impairment is common in peripheral diseases such as chronic kidney disease (CKD), mechanistic insights and effective therapies are lacking. Here, we show that microglial potassium (K+) dyshomeostasis induces noncanonical IL-1β maturation and neuronal dysfunction via IL-1R signaling in CKD. Despite inflammasome activation in the brain, microglial caspase-1 deficiency does not improve inflammation and cognition in CKD mice. Noncanonical IL-1β maturation in microglia is mediated by the cathepsin C–caspase-8 pathway. Restoring K+ homeostasis in microglia or genetically inhibiting neuronal IL-1R1 signaling abolishes CKD-induced cognitive impairment. Microglial K+ dyshomeostasis and noncanonical microglial IL-1β maturation may therefore be druggable targets in some forms of cognitive impairment. These insights identify a new intercellular microglia–neuron crosstalk and identify potential therapeutic targets to combat inflammasome-induced neuronal dysfunction.

Effect of IL-1β on mesenchymal stem cells

Project description:Mesenchymal stem cells are often transplanted in inflammatory environments and they are able to survive and modulate host immune responses through mechanism poorly understood. In this paper we analyzed biological responses of MSC in response IL-1β as a representative inflammatory mediator. Microarray analysis of MSC treated with IL-1β revealed that this cytokine activates a set of biological process related with cell survival, cell migration, cell adhesion, chemokine production, induction of angiogenesis and modulation of immune response. Further analysis by real-time PCR and functional assays revealed that IL-1β mainly increases production of chemokines CCL5, CCL20, CXCL1, CXCL3, CXCL5, CXCL6, CXCL10, CXCL11 and CX3CL1, interleukins IL-6, IL-8, IL23A, IL32, Toll-like receptors TLR2, TLR4, CLDN1, metalloproteins MMP1 and MMP3, growth factors CSF2 and TNF, together with adhesion molecules ICAM1 and ICAM4. Functional analysis of MSC proliferation, migration and adhesion to extracellular matrix components revealed that IL-1β did not affect proliferation whereas constitute a throphic factor for MSC and increases adhesion mainly to collagen and laminin. Moreover, IL-1β treatment enhanced the ability of MSC to recruit monocytes and granulocytes cells in vitro. Blockade of NFkβ transcription factor activation with IκB kinase beta (IKKb) siRNA impaired MSC migration, adhesion and leucocyte recruitment, indicating that NF-kB signaling pathway is the main mechanism implicated in these biological processes. These findings are relevant for designing protocols that implicate MSC delivery into inflammatory environments.

The role of IRAKM in IL-1β-treated adipocytes

Project description:Toll-like receptors/Interleukin-1 receptor (IL-1R) signaling plays an important role in High-fat diet (HFD)-induced adipose tissue dysfunction contributing to obesity-associated metabolic syndromes. Here, we show an unconventional IL-1R-IRAKM (IL-1R-associated kinase M)-Slc25a1 signaling axis in adipocytes that reprograms lipogenesis to promote diet-induced obesity. Adipocyte-specific deficiency of IRAKM reduced HFD-induced body weight gain, increased whole body energy expenditure and improved insulin resistance, associated with decreased lipid accumulation and adipocyte cell sizes. IL-1β stimulation induced the translocation of IRAKM Myddosome to mitochondria to promote de novo lipogenesis in adipocytes. Mechanistically, IRAKM interacts with and phosphorylates mitochondrial citrate carrier Slc25a1 to promote IL-1β-induced mitochondrial citrate transport to cytosol and de novo lipogenesis. Moreover, IRAKM-Slc25a1 axis mediates IL-1β induced Pgc1a acetylation to regulate thermogenic gene expression in adipocytes. IRAKM kinase-inactivation also attenuated HFD-induced obesity. Taken together, our study suggests that the IL-1R-IRAKM-Slc25a1 signaling axis tightly links inflammation and adipocyte metabolism, indicating a novel therapeutic target for obesity.

Sequencing to determine the effect of neuronal IL-1b receptor knockout on the stress effect of paired fighting social defeat in mice

Project description:Chronic stress contributes to the development of psychiatric disorders including anxiety and depression. Several inflammatory-related effects of stress are associated with increased interleukin-1 (IL-1) signaling within the central nervous system and are mediated by IL-1 receptor 1 (IL-1R1) on several distinct cell types. Neuronal IL-1R1 is prominently expressed on the neurons of the dentate gyrus, but its role in mediating behavioral responses to stress is unknown. We hypothesize that IL-1 acts on this subset of hippocampal neurons to influence cognitive and mood alterations with stress. Here, mice subjected to psychosocial stress showed reduced social interaction and impaired working memory, and these deficits were prevented by global IL-1R1 knockout. Selective deletion of IL-1R1 in glutamatergic neurons (nIL-1R1-/-), abundant in the hippocampus wherein the inflammatory-influenced effects were observed, abrogated the stress-induced deficits in social interaction and working memory. RNA-sequencing of microdissected hippocampi revealed that stress increased several canonical pathways (TREM1, NF-κ, complement, IL-6 signaling) and upstream regulators (INFγ, IL-1β, NF-κB, MYD88) associated with inflammation. The inductions of TREM1 signaling, complement, and leukocyte extravasation with stress were reversed by nIL-1R1-/-. Collectively, we show that stress-dependent IL-1R1 signaling in hippocampal neurons represents a novel mechanism by which inflammation is perpetuated and social interactivity and working memory are modulated.

Augmenting SARS-CoV-2 vaccine induced spike protein-specific CD4+ T cell responses through IL-1β and its receptors.

Project description:Immunity to SARS-CoV-2 infection provided by COVID-19 mRNA vaccines decline over time. Thus, there is a need for interventions to augment and sustain such immunity. To address this, we characterized S protein-specific CD4+ T cells in healthy individuals who received COVID-19 mRNA vaccines utilizing high-dimensional single cell RNA-seq and mass cytometry. S protein-specific CD4+ T cells highly expressed IL-1 receptor (R) 1 and its decoy receptor IL-1R2. IL-1b promoted IFN-g expression by S protein-stimulated CD4+ T cells, which was furthered by adding anti-IL-1R2-blocking antibodies, supporting the functional implications of IL-1R1 and IL-1R2. Following the 2nd dose of a COVID-19 mRNA vaccine, IL-1R1 expression increased while IL-1R2 expression decreased in S protein-specific CD4+ T cells. Our findings provide novel insight into augmenting COVID-19 mRNA vaccine-induced CD4+ T cell immunity by modulating IL-1β and its receptor system, which could foster a more effective and prolonged immune response.
