(Submitter supplied) We present an infection study with pathogenic and non-pathogenic mycobacterial strains that have vastly different characteristics. The early/late host response to infection with these detergent-free cultured strains will be analysed through Ampliseq and further validated through qPCR in an attempt to provide information on the subtleties which may ultimately contribute to the virulent phenotype. Proceeding to the next objective of the study is to knock-down (siRNA)/knock-up (saRNA) selected differentially expressed mRNA to study their role in the intracellular survival of M. more...

(Submitter supplied) Infections with mycobacteria, including Mycobacterium tuberculosis (Mtb) and Mycobacterium bovis (M. bovis) BCG, are a leading cause of morbidity and mortality for HIV-infected persons. In contrast to HIV, SIV infection of sooty mangabeys is nonpathogenic, characterized by a lack of clinical disease including an absence of opportunistic infections. The goal of this study was to identify innate immune responses to M. more...

(Submitter supplied) 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). more...

(Submitter supplied) Human alveolar macrophages (HAM) are primary bacterial niche and immune response cells during Mycobacterium tuberculosis (M.tb) infection, and human blood monocyte-derived macrophages (MDM) are a model for investigating M.tb-macrophage interactions. Here, we use a targeted RNA-Seq method to measure transcriptome-wide changes in RNA expression patterns of freshly obtained HAM (used within 6 h) and 6 day cultured MDM upon M.tb infection over time (2, 24 and 72 h), in both uninfected and infected cells from three donors each. more...

(Submitter supplied) This experiment is to compare the transcription patterns of mouse macrophages (J774A.1) infected with BCG, H37Ra and M. smegmatis under high multiplicity of infection (MOI). Through the global transcriptome profiling study, we define a pathogen specific host gene expression pattern and indicate that SRC likely plays a central role in regulating multiple unique signaling pathways activated by MTB infection. more...

Analysis of macrophage cell line J774A.1 infected with pathogenic mycobacteria BCG and H37Ra and non-pathogenic M. smegmatis under high multiplicity of infection (MOI = 50). Results provide insight into the molecular response of macrophage host cells to pathogenic and non-pathogenic mycobacteria.

(Submitter supplied) We analyzed the genes expressed, or the transcriptome, of bacilli Mycobacterium bovis BCG Pasteur (wtBCG) and a mutant strain obtained by transposition of the gene BCG_ BCG_2177c (mtBCG), cultured in the presence of a lipid mixture (fatty acids/cholesterol) as main carbon source. Using RNAseq we identified a group of genes that provides novel insight regarding the metabolic pathways and transcriptional regulation, and pathogenic features that were influenced by BCG_2177c gene, a TetR-like repressor, during the lipid metabolism in slow-growing mycobacteria that could be extrapolated to other members of the MTBC.

(Submitter supplied) Increasing experimental evidence supports that Mycobacterium tuberculosis (Mtb) has evolved strategies to survive within the lysosomes from activated macrophages, which may represent a reservoir for persistent mycobacteria. To further our knowledge in Mtb response to the lysosomal environment, we profiled the global transcriptional activity of Mtb in a lysosomal in vitro exposure (LivE) model. At inhibitory conditions of lysosomal SF (iLivE), which did not kill but arrested mycobacterial replication thereby mimicking persistence, Mtb expresses a unique transcriptome, where genes involved in general stress response, metabolic reprogramming, cell wall remodeling, respiration, oxidative stress and dormancy response were found to be significantly modulated. more...

(Submitter supplied) The goal of this study aims to quantitatively compare the gene expression difference in wild-type or cmtR-deleted strains of Mycobacterium bovis BCG with and without excess zinc treatment at the transcriptome level and find the underlying mechanism how could excess zinc inhibit mycobacterial growth and its relation with transcription factor CmtR.
