(Submitter supplied) Background: Tuberculosis (TB) remains a major public health problem, especially in developing countries, with 1.5 million deaths annually worldwide. Macrophages (Mφs) are central to TB pathogenesis. Mφs play a key role in the outcome of the infection. More importantly, Mφs are the primary cell target of MTB, which has developed different strategies to multiply inside the Mφ phagosome. Here we aim to compare the transcriptome of Mycobacterium tuberculosis (MTB)-infected Mφs with that of cells stimulated with heat-killed MTB. more...

(Submitter supplied) Background: Tuberculosis (TB) remains a major public health problem, especially in developing countries, with 1.5 million deaths annually worldwide. Antibiotics are commonly used in the treatment of bacterial infections. As with most drugs, antibiotic treatment can also alter host metabolism, leading to adverse side-effects. Antibiotics can also interfere with the immune system, indirectly through the disturbance of the body’s microbiota or directly by modulating the functions of immune cells. 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 are thus continually being developed, without their effects on the immune system being studied in-depth. Here we aim to evaluate the impact of a recently release anti-TB drug, named bedaquiline (BDQ), on the response of human macrophages infected with Mycobacterium tuberculosis (MTB). more...

(Submitter supplied) Infectious diseases, such as Mycobacterium tuberculosis (Mtb)-caused tuberculosis (TB), remain a global health threat exacerbated by increasing drug resistance. Host-directed therapy (HDT) is a complementing strategy for infection treatment through targeting host immune mechanisms. However, the limited understanding of the host factors and their regulatory mechanisms involved in host immune defense against infections has impeded HDT development. more...

Analysis of Mycobacterium tuberculosis treated with Bedaquiline (BDQ; Sirturo) and harvested up to 360 min after drug addition. BDQ, an ATP synthase inhibitor, causes bacteriostasis within hours of treatment. Results provide insight into molecular mechanisms underlying BDQ-induced bacterial killing.

(Submitter supplied) The zebrafish Cxcr3.2 is a functional homolog of the human chemokine receptor CXCR3. Zebrafish macrophages lacking this receptor have impaired motility and a rounded shape compared to their wildtype counterparts. To investigate the effects of cxcr3.2 mutation on the transcriptional profile of macrophages, we sorted macrophages from zebrafish larvae lacking a functional cxcr3.2 and compared their transcriptome to that of macrophages from wildtype larvae. more...

(Submitter supplied) The global burden of tuberculosis (TB) is aggravated by the continuously increasing emergence of drug resistance, highlighting the need for innovative therapeutic options. The concept of host-directed therapy (HDT) as adjunctive to classical antibacterial therapy with antibiotics represents a novel and promising approach for treating TB. Here, we have focused on repurposing the clinically used anticancer drug tamoxifen, which was identified as a molecule with strong host-directed activity against intracellular Mycobacterium tuberculosis (Mtb). 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) The mechanisms that govern organelle remodeling remain poorly defined. Lysosomes degrade cargo from various routes including endocytosis, phagocytosis and autophagy. For phagocytes, lysosomes are a kingpin organelle since they are essential to kill pathogens and process and present antigens. During phagocyte activation, lysosomes undergo a striking reorganization, changing from dozens of globular structures to a tubular network, in a process that requires the phosphatidylinositol-3-kinase-AKT-mTOR signalling pathway. 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...

(Submitter supplied) Tuberculosis kills nearly 2 million people through out the world, every year. The outcome of M. tuberculosis infection is determined by the host and bacterial factors. A strong host immune response controls the growth of the bacilli effectively. However, in a host with suboptimal immune response, the bacilli grows and mounts disease. Activation of immune response following M. tuberculosis infection affects the expression of many host genes that are involved in the production of immune system molecules such as cytokines, chemokines, surface receptors and transcriptional regulators that manifest in the change of subsequent cellular events, including chemotaxis and proliferation of effector cells. more...

(Submitter supplied) Comparative analysis of the transcriptional response, as quantified by RNA-Seq, of Mycobacterium tuberculosis (Mtb) during inhibition of the terminal cytochrome oxidases, Cytochrome bd oxidase and Cytochrome bcc:aa3. This study was designed to evaluate the efficacy if a novel small molecule inhibitor of the Cytochrome bd oxidase. Specifically, we compared the transcriptional response of Mtb during inhibition by Q203 with a Cytochrome bd deletion mutant to the transcriptional response of Mtb treated with a combination of Q203 and the purported Cytorchomre bd small molecule inhibitor (ND-011992).
