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.

Project description:This experiement aims to know what the differences of protein translation are in the bone marrow derived macro-phages(BMDMs) from WT mice and Elp3 KO mice. We treated the BMDMs with or without IL-4 for 4 hours.

Project description:To investigate the function OGT in the regulation of M2 polarization of macrophages, we established IL-4-activated bone marrow-derived macrophages (BMDMs) from mice of wild-type control or Lyz2-Cre/Loxp-mediated knockout of OGT. We then performed gene expression profiling analysis using data obtained from RNA-seq of wild-type (WT) and OGT-knockout (OGT-KO) macrophages at two time points during IL-4 (20ng/μl) sitmulation.

Project description:Neutrophil abscess formation is critical in innate immunity against many pathogens. Here, the mechanism of neutrophil abscess formation was investigated using a mouse model of Staphylococcus aureus cutaneous infection. Gene expression analysis of S. aureus-infected skin revealed that induction of neutrophil recruitment genes was largely dependent upon IL-1beta/IL-1R activation. Unexpectedly, using IL 1beta reporter mice, neutrophils were identified as the primary source of IL-1beta at the site of infection. Furthermore, IL-1beta-producing neutrophils were necessary and sufficient for abscess formation and bacterial clearance. S. aureus-induced IL 1beta production by neutrophils required TLR2, NOD2, FPRs and the ASC/NLRP3 inflammasome. Taken together, IL-1beta and neutrophil abscess formation during an infection are functionally, spatially and temporally linked as a consequence of direct IL-1beta production by neutrophils. Lesional skin biopsies obtained from C57BL/6J WT mice or IL-1R-deficient mice at 4 hours post-infection with Staphylococcus aureus. Uninfected skin biopsies were also collected from WT and IL-1R-deficient mice.

Project description:Alternative macrophages are critical in parasites defense, the resolution of inflammation and wound healing. RNA modifications, which are defined as post-transcriptional changes in the chemical composition of RNA molecules, are involved in the immune response.Among tRNA-modifying enzymes which target the tRNA anticodon, Elongator and Cytosolic thiouridylase (Ctu)-1/2 complexes exclusively modify the wobble uridine (U34) base in cytosolic tRNAs. However, the full picture of how mRNA translational factors maintain protein synthesis accuracy and co-translational protein folding are far from being fully understood.To address this question,we evaluated the role of Elp3 on protein in the IL4 induced alternative bone marrow derived macrophages (BMDMs). The BMDMs from widetype and Elp3 myeloid specific knockout mice were treated by IL-4 for 24h or not. Then the aggregates were isolated from these BMDMs and performed by MS.

Project description:To determine the spectrum of miRNA targets regulated following Dicer deletion, we performed argonaute 2 (AGO2)-RNA Immunoprecipitation (RIP)-microarray in bone marrow-derived macrophages (BMDMs) from LysM-Cre/Dicerflox/flox/Apoe–/– and LysM-Cre/Dicerwt/wt/Apoe–/– mice. This analysis combined with miRNA profiling in Dicer wild type (WT) and knockout (KO) BMDMs may help to identify the miRNA targets regulated by Dicer deletion.
