Project description:IL-10 or IL-6 stimulation of control 129xC57BL/6 murine bone marrow derived macrophages in the presence of LPS. We used microarrays to detail the global programme of gene expression changes in response to IL-6 or IL-10 stimulation in the presence of lipopolysaccharide. BMDMs were isolated from control, IL-6-/-, and IL-10-/- mice on a 129XBL/6 mixed background mice and differentiated in the presence of CSF-1 for 6-7 days. Cells were scraped and plated in 6 well plates at 2x10e6/well. Cells were washed with complete DMEM and rested for 1-2 hr before stimulation with combinations of IL-10 (10 ng/ml), IL-6 (2 ng/ml) or LPS (100 ng/ml) for 45 min or 180 mins. Complete biological replicates were performed. Experiment Overall Design: Data sets from wild-type, IL-10-/- and IL-6-/- BMDMs treated with IL-6 or IL-10 in the presence of LPS over time

Project description:Interleukin-10 (IL-10) is a pleiotropic anti-inflammatory cytokine produced and sensed by most hematopoietic cells. Genome wide association studies and experimental animal models point at a central role of the IL-10 axis in Inflammatory Bowel Diseases. Here we investigated the importance of intestinal macrophage production of IL-10 and their IL-10 exposure, as well as the existence of an IL-10-based autocrine regulatory loop in the gut. Specifically, we generated mice harboring IL-10 or IL-10 receptor (IL-10R?) mutations in intestinal lamina propria-resident chemokine receptor CX3CR1hi-expressingmacrophages. We found macrophage-derived IL-10 dispensable for gut homeostasis and maintenance of colonic T regulatory cells. In contrast, loss of IL-10 receptor expression impaired the critical conditioning of these monocyte-derived macrophages, but resulted in spontaneous development of severe colitis. Collectively, our results highlight IL-10 as a critical homeostatic macrophage-conditioning factor in the colon and define intestinal CX3CR1hi macrophages as a decisive factor that determines gut health or inflammation.

Project description:To recruit phagocytes, apoptotic cells characteristically release ATP, which functions as a “danger” signal. Here, we found that the culture supernatant of apoptotic cells activated the macrophages to express anti-inflammatory genes such as NR4A and Thbs1. A high level of AMP accumulated in the apoptotic cell supernatant in a Pannexin1-dependent manner. A nucleotidase inhibitor and A2a adenosine receptor antagonist inhibited the apoptotic supernatant-induced gene expression, suggesting AMP was metabolized to adenosine by an ecto-5’-nucleotidase expressed on macrophages, to activate the macrophage A2a adenosine receptor. Intraperitoneal injection of zymosan into AdoR A2a- or Panx1-deficient mice produced high, sustained levels of inflammatory mediators in the peritoneal lavage. These results indicated that AMP from apoptotic cells suppresses inflammation as a “calm down” signal. If apoptotic cells produce “danger” or “anti-danger” signal(s), we rationalized that such signals would activate gene expression in macrophages. To investigate this possibility, we examined the effect of the culture supernatant from apoptotic cells on macrophage gene expression by using microarrays. For mouse BMDMs, bone marrow cells from female C57BL/6J mice at 8 weeks of age were cultured for more than 7 days with DMEM containing 10% FCS supplemented with mouse M-CSF. We used adherent cells as BMDMs in the study. W3 cells, mouse T cell line expressing Fas, were treated with human Fas ligand at 37°C for 30 min to induce apoptosis. The cells were then washed and re-suspended at a concentration of 1 × 107 cells/ml with RPMI containing 1% FCS, and further incubated for 60 min at 37°C. Following Fas ligand treatment, more than 90% of the W3 cells were Annexin V positive, and only small percentage were positive for both Annexin V and propidium iodide (PI). The culture supernatant was collected from apoptotic W3 cells. Next, BMDMs were incubated with medium (BMDMs-Medium) or apoptotic W3 cell supernatant (BMDMs-Apoptotic cell supernatant) for 1 h. Total RNA was extracted from the cells and hybridized on Affymetrix microarrays.

Project description:Reticuloendothelial macrophages engulf ~0.2 trillion senescent erythrocytes daily in a process called erythrophagocytosis (EP). This critical mechanism preserves systemic heme-iron homeostasis by regulating red blood cell (RBC) catabolism and iron recycling. Although extensive work has demonstrated the various effects on macrophage metabolic reprogramming by stimulation with proinflammatory cytokines, little is known about the impact of EP on the macrophage metabolome and proteome. Thus, we performed mass spectrometry-based metabolomics and proteomics analyses of bone marrow-derived macrophages (BMDMs) before and after EP of IgG-coated RBCs. Further, metabolomics was performed on BMDMs incubated with free IgG to ensure that changes to macrophage metabolism were due to opsonized RBCs and not to free IgG binding. Uniformly labeled tracing experiments were conducted on BMDMs in the presence and absence of IgG-coated RBCs to assess the flux of glucose through the pentose phosphate pathway (PPP). In this study, we demonstrate that EP significantly alters amino acid and fatty acid metabolism, the Krebs cycle, OXPHOS, and arachidonate-linoleate metabolism. Increases in levels of amino acids, lipids and oxylipins, heme products, and RBC-derived proteins are noted in BMDMs following EP. Tracing experiments with U-13C6 glucose indicated a slower flux through glycolysis and enhanced PPP activation. Notably, we show that it is fueled by glucose derived from the macrophages themselves or from the extracellular media prior to EP, but not from opsonized RBCs. The PPP-derived NADPH can then fuel the oxidative burst, leading to the generation of reactive oxygen species necessary to promote digestion of phagocytosed RBC proteins via radical attack. Results were confirmed by redox proteomics experiments, demonstrating the oxidation of Cys152 and Cys94 of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and hemoglobin-β, respectively. Significant increases in early Krebs cycle and C5-branched dibasic acid metabolites (α-ketoglutarate and 2-hydroxyglutarate, respectively) indicate that EP promotes the dysregulation of mitochondrial metabolism. Lastly, EP stimulated aminolevulinic acid (ALA) synthase and arginase activity as indicated by significant accumulations of ALA and ornithine after IgG-mediated RBC ingestion. Importantly, EP-mediated metabolic reprogramming of BMDMs does not occur following exposure to IgG alone. In conclusion, we show that EP reprograms macrophage metabolism and modifies macrophage polarization.

Project description:Alpk1-deficient mice demonstrate exacerbated colitis and increased IL-12/Th1 response upon challenge with an intestinal pathobiont, Helicobacter hepaticus (Hh). Hematopoietic compartment is driving the pathogenic phenotype in this animal model, and Alpk1 is highly expressed in myeloid cells (macrophages and dendritic cells). Alpk1 deficiency has a recessive phenotype, since Alpk1+/- (heterozygous) mice show the same phenotype as the wild type mice. Mouse bone-marrow derived macrophages (BMDMs) show elevated IL-12 production in Alpk1-/- mice in response to stimulation with Hh. Since the molecular mechanism of how Alpk1 deficiency affects macrophage response to Hh is unknown, we aimed to characterise global changes in gene expression in Alpk1+/- vs Alpk1-/- bone-marrow differentiated cells (BMDMs). Cells were isolated from bone marrow of Alpk1+/- and Alpk1-/- (mixture of bone marrows from three mice per genotype) and plated in BMDM differentiation medium (RPMI, 10% FCS, penicillin and streptomycin, 50 micro beta-mercapthoethanol, 20 ng/ml recombinant mouse GM-CSF(Peprotech)), 7 million cells in per 10 sm uncoated TC dish in 10 ml of medium for eight days, extra 10 ml of medium was added to plates at day 4, before collection and replating in 96-well plates, 150 thousand cells/200 microliters of differentiation medium per well in technical triplicates per genotype/stimulation condition (R1-R3 labels of the samples). The following day BMDMs were stimulated with MOI of 10 of Hh and 10ng/ml of mouse IFNg (Peprotech) (Alpk1+/- BMDMs – het _Hh_8h vs Alpk1-/- BMDMs – alpk1_Hh_8h) or IFNg only (het _nonstim_8h vs alpk1_nonstim_8h) before lysis for RNA extraction using Quick-RNA kit from Zymo Research. Purified RNA was submitted to the Welcome Trust Centre for Human Genetics (Oxford) for RNA-Sequencing
