Project description:To compare gene expression changes induced by infection with Mycobacterium tuberculosis (Mtb) with changes induced by purified Mtb products, we infected THP-1 cells with Mtb strain H37Rv or treated with purified Mtb products, then performed RNAseq.

Project description:During lung infection Mycobacterium tuberculosis (Mtb) resides in macrophages and subverts the bactericidal mechanisms of these professional phagocytes. In this work we have analyzed by DNA microarray technique the global transcription profile of Mtb infecting primary human macrophages in order to identify putative bacterial pathogenic factors that can be relevant for the intracellular survival of Mtb. Keywords: time course We compared the global gene expression of the H37Rv strain of Mtb after 4 hours and 24 hours of infection of human macrophage-like THP-1 cells with the gene expression profile of the strain growing exponentially in broth cultures.

Project description:We report the application of RNA-seq technology for high-throughput profiling of gene transcription in RAW264.7 infected with Mycobacterium tuberculosis H37Ra. By obtaining over six billion bases of sequence from mRNA, we generated genome-wide gene transcription maps of RAW264.7 infected with CdhM-related Mycobacterium tuberculosis H37Ra. We find that numerous genes involved in ER stress are significantly affected by CdhM. This finding indicates that CdhM may induce ER stress during Mtb infection of host cells.

Project description:The innate immune system provides the first response to pathogen infection and orchestrates the activation of the adaptive immune system. Though a large component of the innate immune response is common to all infections, pathogen-specific innate immune responses have been documented as well. The innate immune response is thought to be especially critical for fighting infection with Mycobacterium tuberculosis (MTB), the causative agent of tuberculosis (TB). While TB can be a deadly disease, only 5-10% of individuals infected with MTB develop active disease, and this inter-individual variation is, at least partly, heritable. Studies of inter-individual variation in the innate immune response to MTB infection may therefore shed light on the genetic basis for variation in susceptibility to TB. Yet, to date, we still do not know which properties of the innate immune response are specific to MTB infection and which represent a general response to pathogen infection. To begin addressing this gap, we infected macrophages with eight different bacterial pathogens, including different MTB strains and related mycobacteria, and studied the transcriptional response to infection. We found that although the gene expression changes were largely consistent across the bacterial infection treatments, we were able to identify a novel subset of genes whose regulation was affected specifically by infection with mycobacteria. Genetic variants that are associated with regulatory differences in these genes should be considered candidate loci for explaining inter-individual susceptibility TB. RNA-seq of monocyte-derived macrophages isolated from 6 healthy European males at 4, 18, and 48 hours post-infection with the following 8 bacteria: Mycobacterium tuberculosis (MTB) H37Rv, Mycobacterium tuberculosis GC1237, MTB GC1237, bacillus Calmette-Guérin (BCG), Mycobacterium smegmatis, Yersinia pseudotuberculosis, Salmonella typhimurium, and Staphylococcus epidermidis. table-s1.txt is a tab-delimited text file that contains the batch-corrected log2 counts per million for each of the 156 samples, as well as the Ensembl gene ID and gene name. BCG = bacillus Calmette-Guérin GC = Mycobacterium tuberculosis GC1237 Rv = Mycobacterium tuberculosis (MTB) H37Rv Rv+ = heat-inactivated MTB H37Rv Salm = Salmonella typhimurium Smeg = Mycobacterium smegmatis Staph = Staphylococcus epidermidis Yers = Yersinia pseudotuberculosis

Project description:Mycobacterium tuberculosis (Mtb) is well adapted to survive in macrophages and usually subverts the bactericidal mechanisms of these professional phagocytes. The adaptation of Mtb to the intracellular life depends on its ability to regulate the expression of its genes. Among the most important bacterial transcription activators are the sigma factors that bind to the RNA polymerase and give it promotor specificity. Sigma factor E (SigE) controls the expression of genes that are essential for Mtb virulence. Analysis of the macrophage transcriptional response indicated that proteins encoded by the sigE regulon are involved in the modulation of the macrophage inflammatory response. We compared the global gene expression of THP1 macrophages infected with H37Rv and SigE to the gene expression profile of uninfected macrophages.
