Project description:No.1 Vehicle control. Bone marrow derived macrophages were treated with vehicle control for 30 mins. Cells were then lysed and alkylated by IAM, followed by immunoprecipitation of STING protein and gel separation of the protein. After digestion and secondary alkylation by NEM, sample was submitted for MS analysis. No.2 Menadione treated sample. Bone marrow derived macrophages were treated with Menadione for 30 mins. Cells were then lysed and alkylated by IAM, followed by immunoprecipitation of STING protein and gel separation of the protein. After digestion and secondary alkylation by NEM, sample was submitted for MS analysis.

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:The aim of this study was to identify the signaling pathways differentially engaged upon infection with either live or heat killed Mycobacterium tuberculosis in murine bone marrow derived macrophages. Based on preliminary data that type I IFN signaling dominates the transcriptional differences, we investigated what roles the type I IFN receptor IFNAR and the signaling molecule STING play during infection with either live or heat killed Mycobacterium tuberculosis in bone marrow derived macrophages. In WT and STING KO macrophages, IFNbeta treatment was added either by itself or in addition to both of the infection conditions to test whether the lack of IFNbeta induction in these cells accounted for any differences in transcriptional respones.added IFNbeta treatment either by itself or in addition to both of the infection conditions.

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 DMBA or acetone treated wild type (WT) or STING deficient (SKO) mouse skin or skin tumor was examined for gene expression.

Project description:The model was constructed to describe TLR4 induced NF-κB activation in native bone marrow-derived macrophages. It included processes of ligand (lipopolysaccharide) recognition, formation of dimer receptor complex and further signal transduction through TRAF6/TAK1 complex that leads to the activation of IKKα/β kinase, which in turn enables the NF-κB transcription factor phosphorylation and translocation in the cell nucleus, and induction of IkB and WIP1 (as an example of induced protein that promotes NF-κB dephosphorylation 2) gene transcription. Models were based on the current knowledge of TLR signaling framework, protein interactions within the TLR4 pathway, and up-to-date mathematical models describing Toll receptor activation.
The major important additions were made to TLR4 signaling description:
1) Receptor dimerization process
2) The existence of a basal nuclear NF-κB level (translocation)
3) NF-κB phosphorylation by IKK complex
