Project description:To investigate the extent to which macrophages respond to Salmonella infection, researchers infected RAW 264.7 macrophages with Salmonella enterica serotype Typhimurium and analyzed macrophage proteins at various time points following infection by using a global proteomic approach.

Project description:SrfJ is an effector of the type III secretion systems of the Gram-negative intracellular pathogen Salmonella enterica serovar Typhimurium. To study the effects of this effector on global gene expression in host cells, we have infected murine RAW264.7 macrophages with two strains of Salmonella enterica serovar Typhimurium. The comparison between cells infected with the wild-type strain and cells infected with a srfJ mutant revealed a number of genes that are differentially expressed when SrfJ is present.

Project description:To identify bacterial transcripts that may be associated with type I IFN production in Salmonella enterica subsp typhimurium (SL1344) infected macrophages we transformed macrophages with an ISRE-GFP reporter construct and sorted separate populations of GFP positive and GFP negative infected macrophages. We then did whole transcriptome profiling, collecting both host and bacterial transcripts, for differential expression analysis

Project description:To identify bacterial transcripts that may be associated with type I IFN production in Salmonella enterica subsp typhimurium (SL1344) infected macrophages we transformed macrophages with an ISRE-GFP reporter construct and sorted separate populations of GFP positive and GFP negative infected macrophages. We then did whole transcriptome profiling, collecting both host and bacterial transcripts, for differential expression analysis Analysis of ISRE positive, negative, and mixed populations at two time points (unexposed and 24hours) in duplicate (biological replicates). A sample consisting of Salmonella prior to infection was also included

Project description:We used microarrays to detail the global programme of gene expression in human macrophages infected in vitro with HIV-1 or not and then subjected to contact with Salmonella Typhimurium ST313 or ST19 strains; we identified distinct classes of differentially regulated genes during this process

Project description:Salmonella enterica is one of the most important foodborne pathogens that infect a variety of animals and birds. In humans, S. Typhimurium causes gastroenteritis, leading to vomiting, diarrhea, fever, and abdominal cramps. We mainly get infected with Salmonella by ingesting comminated poultry products. Therefore, developing an oral live attenuated vaccine for the poultry industry is our best bet against Salmonella infection. In this article, we investigated the potential of the next generation of Salmonella vaccines. We generated a library of potentially attenuated S. Typhimurium mutants and compared fitness to that of a commercial vaccine. We also investigated the invasion and survival potential of these mutants in chicken macrophages. Our data indicate that although these mutants had no significant growth defects, they were much sensitive to macrophage attack. Analyzing the transcriptome data from infected primary chicken macrophages, we concluded that these mutants elicit a robust immune response by activating several immunoregulatory pathways. Our data also indicates that by combining phoPQ deletion with an already existing cya-crp deletion in MeganVac1, a much stronger immune response can be generated.

Project description:Purpose: The goals of this study are to compare hnRNP M shRNA knockdown macrophages to scramble shRNA control macrophages in uninfected cells and Salmonella Typhimurium-infecetd cells to unbiasly look at gene expression changes that are regulated by the splicing factor, hnRNP M during resting state and during an innate immune response. Methods: Macrophage mRNA profiles of uninfected and Salmonella Typhimurium-infected hnRNP M knockdown cells lines and SCR shRNA control RAW264.7 macrophages were generated by sequencing, in triplicate, using Illumina 1.9 system. The sequence reads that passed quality filters were analyzed at the gene expression level with CLC Genomics Workbench 8 with Transcriptomeics Analysis followed by statistical analysi with Empiciral Analysis of DGE and (EDGE test) and Baggerly's test. qRT–PCR validation was performed using SYBR Green assays. Results: Using CLC Genomics Workbench 8 transcriptomics workflow, we mapped about 30 million sequence reads per sample to the mouse genome (GRCm38). Approximately 140 transcripts showed differential expression between the scramble control and hnRNP M knockdown macrophages in uninfected cells, with a fold change ≥1.5 and p value <0.05. Additionally, ~150 transcripts showed differential expression between the scramble control and hnRNP M knockdown macrophages in Salmonella-Typhimurium cells, with a fold change ≥1.5 and p value <0.05. Altered expression of genes was confirmed with qRT–PCR, demonstrating the effectiveness of the RNA-seq method. Conclusions: Our study demonstrates hnRNP M-dependent differential gene expression in the context of the innate immune response.
