Expression Data from Toxoplasma gondii-Infected Murine Bone Marrow-Derived Macrophages

ABSTRACT: We wanted to determine how type II Toxoplasma GRA15 and type I ROP16 affect host gene expression. We infected bone marrow-derived macrophages (BMMs) from B6 mice with type II (Pru), type II +ROP16 I, type II ?gra15, or type II ?gra15 + ROP16I. BMMs were plated, then infected with parasites for 18 hours. RNA was harvested from the cells by Trizol.

Expression Data from Toxoplasma gondii-Infected Murine Bone Marrow-Derived Macrophages

Project description:We wanted to determine how type II Toxoplasma GRA15 and type I ROP16 affect host gene expression. We infected bone marrow-derived macrophages (BMMs) from B6 mice with type II (Pru), type II +ROP16 I, type II Δgra15, or type II Δgra15 + ROP16I.

Gene expression Data from Toxoplasma gondii-Infected Murine Bone Marrow-Derived STAT6 and STAT3 Deficient Macrophages

Project description:The Toxoplasma type I ROP16 kinase directly activates the host STAT3 and STAT6 transcription factors and regulates the expression of many host genes. However, many of genes lack known STAT3/6 transcription factor binding sites in their promoter regions. We wanted to understand what fraction of host genes that are modulated by ROP16 were dependent on the STAT3 and STAT6 signaling pathways. Bone marrow-derived macrophages (BMMs) from mLys-Mcre Stat3fl/fl mice were infected with type II (Pru A7), type II +ROP16 I, type II Δgra15, or type II Δgra15 + ROP16I and gene expression was analyzed 18 hrs after infection. This data set was generated side by side with infections performed in B6 BMDMs, the gene expression results for that experiment were previoiusly submitted under the GEO accession number GSE29404. In addition, gene expression of wild type B6 and Stat6-/- BMDMs were infected with the II+ROP16I strain.

Expression data from RAW264.7 murine macrophages infected with Toxoplasma gondii and subsequently stimulated with interferon-gamma

Project description:Toxoplasma strains are known to inhibit the expression of several interferon-gamma induced genes, and a type II strain was shown to dysregulate genome-wide responses to interferon-gamma in human fibroblasts (Kim et al., 2007, J Immunol.). In this study we aimed to determine the effect of infection with three clonal lineages of Toxoplasma, type I, II, and III strains on genome-wide interferon-gamma induced transcription in murine macrophages. We also assessed the effect of the two main Toxoplasma modulators of mouse macrophage transcription, ROP16 and GRA15 (Jensen et al., 2011, Cell Host Microbe). We used Affymetrix microarrays to analyze host cell transcription after Toxoplasma infection and interferon-gamma stimulation. RAW264.7 murine macrophages were left uninfected or infected with type I (RH), type I ?rop16 (RH ?rop16), type II (Pru), type II ?gra15 (Pru ?gra15), or type II (CEP) parasites at an MOI ~5 for 18 hours and subsequently stimulated with murine IFN-? for six hours. Plaque assays were done to assess parasite viability. Total RNA was isolated and hybridized to Affymetrix Mouse 430A 2.0 gene chips.

Expression data from Human foreskin fibroblasts (HFFs) infected with Toxoplasma gondii.

Project description:Toxoplasma strains have been shown to modulate host cell transcription. We have found a type II Toxoplasma gene, GRA15, which activates the nuclear translocation of the NF-kappaB p65 transcription factor. We used microarrays to determine how GRA15II modulates host cell transcription. HFFs were infected with type I (RH), type I GRA15II (RH GRA15II), type II (Pru), type II GRA15KO (Pru GRA15KO), type III (cep), or type III GRA15II (cep GRA15II) parasites for 18-24 hours. Some samples were also stimulated with TNF-alpha. Total RNA was isolated and hybridized to Affymetrix GeneChip Human Genome U133A 2.0 arrays.

Expression data from WT or p65-/- mouse embryonic fibroblasts (MEFs) infected with Toxoplasma gondii.

Project description:Toxoplasma strains have been shown to modulate host cell transcription. We have found a type II Toxoplasma gene, GRA15, which activates the nuclear translocation of the NF-kappaB p65 transcription factor. We used microarrays to determine how GRA15II modulates host cell transcription, and whether this transcription is dependent on the p65 transcription factor. WT or p65-/- MEFs were infected with type I (RH), type I GRA15II (RH GRA15II), type II (Pru), or type II GRA15KO (Pru GRA15KO) parasites for 18-24 hours. Total RNA was isolated and hybridized to Affymetrix GeneChip Human Genome U133A 2.0 arrays.

The genetic basis for differential macrophage activation

Project description:Differential macrophage activation mediate genetic differences to a variety of inflammatory pathologies. We wanted to elucidate the transcriptional and regulatory programs regulating differential macrophage activation in genetically diverse mouse strains. Bone marrow-derived macrophages (BMDMs) from AJ and C57BL/6j mice were left unstimulated, stimulated with IFN/TNF, or IL-4, or CpG, or LPS or IFN/TNF and infected with a type II (Pru A7) strain of Toxoplasma gondii, or infected with Pru A7 and gene expression analyzed 18 hrs later.

Gene expression profiles of the small intestine and Peyer's patches from mice that were orally infected with Toxoplasma

Project description:The Toxoplasma type I ROP16 kinase directly activates the host STAT3 and STAT6 transcription factors and when transgenically expressed in the orally virulent type II strain, promotes host resistance to oral challenge. The transcriptional profile of type II and II+ROP16I infected Peyer's patches and intestines from orally infected mice on day 5 was determined to elucidate host signaling pathways and molecular gene targets that correlate with protective immunity in the gut of orally challenged animals

Project description:To identify accessible chromatin regions in the human host cells during Toxoplasma parasite infection (uninfected, RH-infected and Pru-infected human foreskin fibroblasts) and in the obligate intracellular parasite Toxoplasma gondii (Type 1 RH strain and Type 2 Pru strain), ATAC-seq was performed.
