(Submitter supplied) Macrophages play an essential role in the early immune response to Mycobacterium tuberculosis and are the cell type preferentially infected in vivo. Primary macrophages and macrophage-like cell lines are commonly used as infection models, although the physiological relevance of cell lines, particularly for host-pathogen interaction studies, is debatable. Here we use high-throughput RNA-sequencing to analyse transcriptome dynamics of two macrophage models in response to M. more...

(Submitter supplied) Understanding the mechanisms of host macrophage responses to Mycobacterium tuberculosis (M.tb.) is essential for uncovering potential avenues of intervention to boost host resistance to infection. Macrophage transcriptome profiling revealed M.tb. infection strongly induced expression of several enzymes controlling tryptophan (Trp) catabolism. This included indole 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO2), which catalyze the rate-limiting step in the kynurenine pathway, producing ligands for the aryl hydrocarbon receptor (AHR). more...

(Submitter supplied) The W-Beijing family of Mycobacterium tuberculosis (Mtb) strains is known for its high-prevalence and -virulence, as well as for its genetic diversity, as recently reported by our laboratories and others. However, little is known about how the immune system responds to these strains. To explore this issue, here we used reverse engineering and genome-wide expression profiling of human macrophage-like THP-1 cells infected by different Mtb strains of the W-Beijing family, as well as by the reference laboratory strain H37Rv. 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) How the complex interaction between Mycobacterium tuberculosis (Mtb) and the host is regulated during infection is still not well understood. Using a systems biology approach, we demonstrate here that miR-155 is one of several microRNAs that regulate host gene expression over the first 48 hours of Mtb infection in macrophages. miR-155 regulates the cell survival of Mtb-infected macrophages through SHIP1/AKT signaling. more...

(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) Tuberculosis remains a major cause of death from an infectious disease worldwide, yet only 10% of people infected with Mycobacterium tuberculosis develop disease. Defining both necessary and sufficient immunologic determinants of protection remains a great scientific challenge. Analysis of peripheral blood gene expression profiles of active tuberculosis patients has identified correlates of risk for disease or pathogenesis. more...

(Submitter supplied) Mycobacterium tuberculosis (M. tuberculosis) survives and multiplies inside human macrophages by subversion of immune mechanisms. Although these immune evasion strategies are well characterised functionally, the underlying molecular mechanisms are poorly understood. Here we show that during infection of human whole blood with M. tuberculosis, host gene transcriptional suppression, rather than activation, is the predominant response. more...

(Submitter supplied) Background: Infectious diseases are still a leading cause of death and, with the emergence of drug resistance, pose a great threat to human health. New drugs and strategies are thus urgently needed to improve treatment efficacy and limit drug-associated side effects. Nanotechnology-based drug delivery systems are promising approaches, offering hope in the fight against drug resistant bacteria. However, how nanocarriers influence the response of innate immune cells to bacterial infection is mostly unknown. more...
