Project description:To provide a global perspective on the relationships between macrophage activation programs and to understand how certain pathogens circumvent them, we used transcriptional profiling by genome wide microarray analysis to compare the responses of mouse macrophages following exposure to the intracellular parasites Trypanosoma cruzi and Leishmania mexicana, the bacterial product lipopolysaccharide (LPS), and the cytokines IFNG, TNF, IFNB, IL-4, IL-10, and IL-17. We found that LPS induced a classical activation state that resembled macrophage stimulation by the Th1 cytokines IFNG and TNF. However, infection by the protozoan pathogen Leishmania mexicana produced so few transcriptional changes that the infected macrophages were almost indistinguishable from uninfected cells. Trypanosoma cruzi activated macrophages produced a transcriptional signature characterized by the induction of interferon-stimulated genes by 24 h post-infection. Despite this delayed IFN response by T. cruzi, the transcriptional response of macrophages infected by the kinetoplastid pathogens more closely resembled the transcriptional response of macrophages stimulated by the cytokines IL-4, IL-10, and IL-17 than macrophages stimulated by Th1 cytokines. Keywords: Bone marrow macrophage response to intracellular parasites and cytokines We analyzed a series MEEBO arrays on which were hybed RNA amplified from bone marrow-derived macrophages from C57BL/6 mice. Macrophages infected with L. mexicana or T. cruzi or stimulated by LPS, IFNG, IL-4, IL-10, TNF, IFNB, or IL-17 were compared to one another as well as to uninfected, unstimulated control macrophages. All experiments were performed over a 24 h timecourse with timepoints taken at 2 h, 6 h, 12 h, and 24 h.

Project description:We used microarrays to compare interferon-alpha (IFNa)- and interferon-gamma (IFNg)-stimulated genes under an equivalent biological input. The goal was to compare IFNa- and IFNg-stimulated genes, as well as to identify common and distinct sets of type I and II ISGs. Bone marrow macrophages derived from mouse bone marrow in M-CSF for 7 days. The cells were stimulated with 62U/mL IFNa and 1U/mL of IFNg for 2.5 hrs in culture. These concentrations induced equivalent STAT1 phosphorylation in BMMs.

Project description:Mouse bone marrow-derived macrophages (BMDM) grown in macrophage colony-stimulating factor (CSF-1) have been used widely in studies of macrophage biology and the response to toll-like receptor agonists. We investigated whether similar cells could be derived from the domestic pig. Cultivation of pig bone marrow cells for 5-7 days in presence of rhCSF-1 generated a pure population of BMDM that expressed the usual macrophage markers (CD14, CD16, CD163, CD172a), are potent phagocytic cells and produced tumor necrosis factor (TNF) in response to lipopolysaccharide (LPS). Bone marrow cells could be stored frozen and thawed, providing a renewable resource. We profiled gene expression in pig BMDM from outbred animals (Large-White Landrace F1cross) responding to LPS using Affymetrix microarrays. The temporal cascade of inducible and repressible genes more closely-resembled human than mouse macrophages, and included genes involved in tryptophan metabolism (IDO, KYN), lymphoattractant chemokines (CCL20) and the vitamin D3-converting enzyme Cyp27B1. Conversely, pig BMDM, like human macrophages, did not induce genes involved in arginine metabolism, nor did they produce nitric oxide. The data establish pig BMDM as an alternative tractable model for the study of macrophage transcriptional control. RNA for gene expression analysis was collected at time points 0, 2, 7 and 24 hours post LPS stimulation (100ng/ml). Each time point included BMDM from the same three pigs and each cell culture was replicated. The replicate of the pig3_24h was not suitable for RNA analysis. Therefore, a total of 23 microarrays were hybridized.

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
