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:Investigation of whole genome gene expression level changes in BMDM adhered for 4 or 18hrs to Lab Tek Chamber slides pre-coated with 4ug/ml of human serum albumin (HSA) (control protein) or purified human C1q and treated with lipopolysaccharide (LPS: 20ng/ml) Mycobacterium avium 101 (M avium) or apoptotic Jurkat T cells. BMDM were obtained from C57Bl/6 and generated as previously described in Bohlson, SS, Strasser, JA, Bower JJ, Schorey J S 2001 Role of complement in Mycobacterium avium pathogenesis: in vivo and in vitro analyses of the host response to infection in the absence of complement component C3 Infec Immun 69: 7729-7735. Mybacterium avium 101 was obtained from Dr Jeff Schorey (University of Notre Dame). The human Jurkat T cell line was obtained from ATCC (Manassas, VA) and induced to undergo apoptosis with dexamethasone as described in Lillis, AP, Greenlee, M C, Mikhailenko I, Pizzo, S V, Tenner, A J, Strickland, D K, Bohlson, S S 2008 Murine Low-Density Lipoprotein Receptor-Related Protein 1 (LRP) Is Required for Phagocytosis of Targets Bearing LRP Ligands but Is Not Required for C1q-triggered Enhancement of Phagocytosis J Immunol 181: 364: 373. A six chip study using total RNA from 5 separate cultures of BMDM adhered to HSA for 4 hrs, 5 separate cultures of BMDM adhered to C1q for 4 hrs, 5 separate cultures of BMDM adhered to HSA for 4 hrs and infected with M avium at a 1:500 ratio of BMDM to M avium, 5 separate cultures of BMDM adhered to C1q for 4hrs and infected with M avium at a 1:500 ratio ofBMDM to M avium, 5 separate cultures of BMDM adhered to HSA for 4 hrs and infected with M avium at a 1:1000 ratio of BMDM to M avium, 5 separate cultures of BMDM adhered to HSA for 4 hrs and treated with 20ng/ml LPS, 5 separate cultures of BMDM adhered to C1q for 4 hrs and treated with 20ng/ml LPS, 5 separate cultures of BMDM adhered to HSA for 4 hrs and treated with 20ng/ml LPS and co-cultured with apoptotic Jurkat cells at a 1:3 ratio of BMDM to apoptotic cells, 5 separate cultures of BMDM adhered to C1q for 4 hrs and treated with 20ng/ml LPS and co-cultured with apoptotic Jurkat cells at a 1:3 ratio of BMDM to apoptotic cells, 5 separate cultures of BMDM adhered to HSA for 18 hrs, 5 separate cultures of BMDM adhered to C1q for 18 hrs, 5 separate cultures of BMDM adhered to HSA for 18 hrs and infected with M avium at a 1:500 ratio of BMDM to M avium, 5 separate cultures of BMDM adhered to C1q for 18hrs and infected with M avium at a 1:500 ratio of BMDM to M avium, 5 separate cultures of BMDM adhered to HSA for 18 hrs and infected with M avium at a 1:1000 ratio of BMDM to M avium. The chip utilized for these studies is a mouse whole-genome 12-plex expression microarray design by NimbleGen designed from the MM9 genome Candidate probe sequences were verified to have no cross-hybridization to human (HG19) or Mycobacterium avium (NC_008595) targets Note: Study sample BMDM_HSA & M avium (1:500)_18hr_rep2 was not included in this submission due to quality control concerns.
