Project description:Chronic stimulation of innate immune pathways by microbial agents or damaged tissue is known to promote inflammation-driven tumorigenesis by unclarified mechanisms1-3. Here we demonstrate that mutagenic 7,12-dimethylbenz(a)anthracene (DMBA), etoposide or cisplatin induces nuclear DNA leakage into the cytosol to intrinsically activate STING (Stimulator of Interferon Genes) dependent cytokine production. Inflammatory cytokine levels were subsequently augmented in a STING-dependent extrinsic manner by infiltrating phagocytes purging dying cells. Consequently, STING-/- mice, or wild type mice adoptively transferred with STING-/- bone marrow, were almost completely resistant to DMBA-induced skin carcinogenesis compared to their wild type counterparts. Our data emphasizes, for the first time, a role for STING in the induction of cancer, sheds significant insight into the causes of inflammation-driven carcinogenesis, and may provide therapeutic strategies to help prevent malignant disease Total RNA obtained from wild type murine embryonic fibroblasts (WT MEFs), STING deficient MEFs (SKO), Trex1 deficient MEFs (TKO), and both STING and Trex1 deficient MEFs (STKO) treated with DMBA and examined cytokine production by these cells.

Project description:To induce chronic IFN-I activation, we injected wildtype and Ifnar1–/– mice with five treatments of DMXAA, a STING agonist, followed by snRNA-seq analysis of hippocampal tissues. In wildtype mice, we showed that microglia had the strongest IFN response to STING activation of all cell types. Ablation of interferon alpha and beta receptor 1 (IFNAR1) abolished microglial IFN-I response and suppression of neuronal MEF2C transcriptional network

Project description:Inflammatory diseases such as Aicardi-Goutieres Syndrome (AGS) and severe systemic lupus erythematosus (SLE) are generally lethal disorders that have been traced to defects in the exonuclease Trex1 (DNAseIII). Mice lacking Trex1 similarly die at an early age through comparable symptoms, including inflammatory myocarditis, through chronic activation of the STING (stimulator of interferon genes) pathway. Here we demonstrate that phagocytes rather than myocytes are predominantly responsible for causing inflammation, an outcome that could be alleviated following adoptive transfer of normal bone marrow into Trex1-/- mice. Trex1-/- macrophages did not exhibit significant augmented ability to produce pro-inflammatory cytokines compared to normal macrophages following exposure to STING-dependent activators, but rather appeared chronically stimulated by genomic DNA. These results shed molecular insight into inflammation and provide concepts for the design of new therapies.

Project description:We report positional cloning and characterization of a novel Sting allele that fails to activate IFN production in the wild-derived mice of MOLF/Ei strain in response to HSV (Herpes Simplex Virus) and Listeria monocytogenes both in vitro and in vivo. We show that previously uncharacterized mutations in the N-terminal of STING are responsible for low levels of IFN due to failure of MOLF STING to respond to cytosolic STING agonists such as 2â3âcGAMP, 5,6-Dimethylxanthenone-4-acetic acid (DMXAA) or poly(deoxyadenylic-deoxythymidylic) acid (dAdT). Using Next-Generation Sequencing (NGS) for the analysis of DNA-responses in congenic C57BL6.StingMOLF/MOLF (MOLF STING) mouse macrophages, we show that these mutations in MOLF/Ei discriminate in responses between different STING agonists. Macrophages from C57BL6.StingB6/B6¬ (B6 STING), or B6 STING expressing littermates were stimulated as a positive control for STING activation, and STING -/- (STING KO) macrophages served as a negative control. To examine differential gene regulation downstream of murine Tmem173 (STING) allelic variants. We stimulated macrophages from B6 mice congenic for MOLF STING; macrophages from B6 STING expressing littermates were stimulated as a positive control for STING activation, and STING -/- (STING KO) macrophages served as a negative control. One replicate of RNA-seq reads after each stimulation provided. Conditions are peritoneal macrophages from B6 congenic mice expressing: B6 STING, MOLF STING, or STING KO stimulated with 2â3âcGAMP, 5,6-Dimethylxanthenone-4-acetic acid (DMXAA), poly(deoxyadenylic-deoxythymidylic) acid (dAdT), or no treatment. This constitutes a total of 12 reads analyzed in this data set.
