Interleukin-1β induces mitochondrial DAMP production to activate STING-dependent innate immune programs

ABSTRACT: Here we report that exogenous IL-1β induces TBK1-mediated interferon regulatory factor 3 (IRF3) activation and autophagic flux in human myeloid and epithelial cells. IL-1β-induced innate immune activation is dependent upon the DNA sensing pathway adaptor, stimulator of interferon genes (STING), through the recognition of mitochondrial DNA by cyclic GMP-AMP synthase (cGAS). Thus, IL-1β potentiates pathogen-induced interferon production and signal transducer and activator of transcription (STAT) signaling to amplify innate immune responses.

Cyclic-Di-Nucleotides Trigger ULK1 (ATG1) Phosphorylation of STING to Prevent Sustained Innate Immune Signaling

Project description:Activation of the STING (Stimulator of Interferon Genes) pathway by microbial or self-DNA, as well as cyclic di nucleotides (CDN), results in the induction of numerous genes that suppress pathogen replication and facilitate adaptive immunity. However, sustained gene transcription is rigidly prevented to avoid lethal STING-dependent pro-inflammatory disease by mechanisms that remain unknown. We demonstrate here that after autophagy-dependent STING delivery of TBK1 (TANK-binding kinase 1) to endosomal/lysosomal compartments and activation of transcription factors IRF3 (interferon regulatory factors 3) and NF-κB (nuclear factor kappa beta), that STING is subsequently phosphorylated by serine/threonine UNC-51-like kinase (ULK1/ATG1) and IRF3 function is suppressed. ULK1 activation occurred following disassociation from its repressor adenine monophosphate activated protein kinase (AMPK), and was elicited by CDN’S generated by the cGAMP synthase, cGAS. Thus, while CDN’s may initially facilitate STING function, they subsequently trigger negative-feedback control of STING activity, thus preventing the persistent transcription of innate immune genes. Total RNA obtained from primary STING deficient mouse embryonic fibroblast reconstituted with mSTING (W), S365A variant (A), or S365D variant (D). These cells were transfected with dsDNA (ISD) for 3 hours.

IL-1B signaling in dendritic cells induces antiviral interferon responses

Project description:Activation of interferon-stimulated gene (ISG) responses is critical for control of viral infection. We recently identified that stimulation of the NLRP3 inflammasome and mobilization of the inflammatory cytokine IL-1β act as critical host restrictive pathways against West Nile virus (WNV) in a mechanism dependent on the regulation of ISGs. In order to define the mechanism by which IL-1β regulates these antiviral immune programs, we utilized global transcriptome analysis in myeloid cells, known targets of WNV replication to define gene signatures required for IL-1β driven antiviral responses. Surprisingly, we found IL-1β dependent activation of interferon-beta (IFN-β) and ISGs at late times following IL-1β treatment. Expression of these antiviral innate immune genes was found to be dependent on activation of IRF3 and appears to reflect a general shift in IL-1β signaling from an inflammatory response early following treatment to an anti-inflammatory type-I IFN mediated response at later times post-treatment. These data demonstrate that inflammatory and antiviral signals integrate to control viral infection. Strategies to co-opt these cytokine activated antiviral signatures can act as novel targeted therapeutic strategies tailored specifically to individual pathogens.

Expression data from IL-1β-stimulated immature human enterocytes treated with probiotic-conditioned media

Project description:The conditioned media from Bifidobacterium infantis (BCM) and Lactobacillus acidophilus (LCM) were reported to promote maturation of innate immune response gene expression, which explained the protective effects of probiotics in clinical necrotizing enterocolitis. We used microarray analysis to investigate the expression of genes involved in regulation of BCM and LCM in IL-1β stimulated immature human enterocytes. The H4 cells (a human nontransformed primary intestinal epithelial cell line) were pretreated with BCM or LCM (15%) for 30 minutes, and then stimulated with or without IL-1β (10 ng/mL) for 4 h. Cell media and IL-1β stimulation were negative and positive control, respectively. RNA was extracted for mcroarray analysis. A total of six treatments (triplicates for each) were included in this study. As one RNA sample in IL-1β-stimulated cells treated with BCM was dropped due to bad quality, seventeen samples were analyzed. Various treatments were compared to the nagative control (cell media alone). Genes with a fold-change ≥2 and a p value ≤ 0.05 were selected.

Proximity proteomics reveals UCH-L1 as an essentialregulator of NLRP3-mediated IL-1β production in humanmacrophages and microglia

Project description:Activation of the NACHT, LRR family pyrin domain containing 3 (NLRP3) inflammasome complex is an essential innate immune signalling mechanism. To reveal how NLRP3 inflammasome assembly and activation are controlled, in particular by components of the ubiquitin system, proximity labelling, affinity purification and RNAi screening approaches were performed. Our study provides an intricate time-resolved molecular map of different phases of NLRP3 inflammasome activation. We discovered that ubiquitin C-terminal hydrolase 1 (UCH-L1) interacts with the NACHT domain of NLRP3, and downregulation of UCH-L1 decreases pro-IL-1β levels. UCH-L1 chemical inhibition with small molecules interfered with NLRP3 puncta formation and ASC oligomerisation, leading to altered IL-1β cleavage and secretion, particularly in microglia cells, which exhibited elevated UCH-L1 expression as compared to monocytes/macrophages. Altogether, we profiled NLRP3 inflammasome activation dynamics and highlight UCH-L1 as an important modulator of NLRP3-mediated IL-1β production, suggesting that a pharmacological inhibitor of UCH-L1 may decrease inflammation-associated pathologies.

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.
