Identification of an Increased Alveolar Macrophage Subpopulation in Old Mice That Displays Unique Inflammatory Characteristics and Is Permissive to Mycobacterium tuberculosis Infection.
Abstract The elderly population is more susceptible to pulmonary infections, including tuberculosis. In this article, we characterize the impact of aging on the phenotype of mouse alveolar macrophages (AMs) and their response to Mycobacterium tuberculosis. Uninfected AMs were isolated from bronchoalveolar lavage of young (3 mo) and old (18 mo) C57BL/6 mice. AMs from old mice expressed higher mRNA levels of CCL2, IFN-β, IL-10, IL-12p40, TNF-α, and MIF than young mice, and old mice contained higher levels of CCL2, IL-1β, IFN-β, and MIF in their alveolar lining fluid. We identified two distinct A...

Experimental Evidence for Limited in vivo Virulence of Mycobacterium africanum
In this study, we used the mouse model of infection to follow the dynamics of M. africanum infection in terms of bacterial burdens and tissue pathology, as well as the immune response triggered. Our findings support a lower virulence of M. africanum as compared to M. tuberculosis, including in mice lacking IFN-γ, a major protective cytokine in tuberculosis. Furthermore, the lung immune response triggered by M. africanum infection in wild-type animals was characterized by a discrete influx of leukocytes and a modest transcriptional upregulation of inflammatory mediators. Our findings contribute to elucidate the pathog...

Genome-Wide miRNA Analysis Identifies Potential Biomarkers in Distinguishing Tuberculous and Viral Meningitis
Tuberculous meningitis (TBM) is the most common and severe form of central nervous system tuberculosis. Due to the non-specific clinical presentation and lack of efficient diagnosis methods, it is difficult to discriminate TBM from other frequent types of meningitis, especially viral meningitis (VM). In order to identify the potential biomarkers for discriminating TBM and VM and to reveal the different pathophysiological processes between TBM and VM, a genome-wide miRNA screening of PBMCs from TBM, VM, and healthy controls (HCs) using microarray assay was performed (12 samples). Twenty-eight differentially expressed miRNAs...

Unilateral acute posterior multifocal placoid pigment epitheliopathy in a patient with a strongly positive purified protein derivative test
ABSTRACT A 27-year-old man presented with a complaint of decreased visual acuity in the right eye. Best-corrected visual acuity was 20/60 in the right eye and 20/20 in the left eye. Right eye fundoscopy revealed mild vitritis, multifocal yellowish lesions, and macular serous retinal detachment. Left eye evaluation was normal. Acute posterior multifocal placoid pigment epitheliopathy was diagnosed in the right eye. Complementary exams revealed a strong reaction to the Mycobacterium tuberculosis purified protein derivative test, thus treatment for tuberculosis was initiated. Baseline fluorescein angiography of the right eye ...

Discrete cutaneous lesions in a critically ill patient treated only for AIDS and miliary tuberculosis: a case report of disseminated histoplasmosis
Histoplasmosis is a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum, with disseminated histoplasmosis (HD) being one of its clinical forms. As a consequence of the HIV-AIDS pandemic, HD has become prevalent not only in regions that are recognized as endemic but also in areas not considered endemic, such as Europe and Asia. Its clinical manifestations are varied and mimic several infectious diseases, mainly tuberculosis. In endemic areas, it is the first manifestation of AIDS in 50 to 70% of patients. The diagnosis of histoplasmosis is difficult and HD can lead to death if not diagnosed early and if p...

Adaptation of Mycobacterium tuberculosis to biofilm growth is genetically linked to drug tolerance.
Abstract Mycobacterium tuberculosis (Mtb) spontaneously grows at the air-medium interface forming pellicle biofilms, which harbor more drug tolerant persisters than planktonic cultures. The underlying basis for increased persisters in Mtb biofilms is unknown. Using a Tn-seq approach, we show here that multiple genes that are necessary for fitness of Mtb cells within biofilms, but not in planktonic cultures, are also implicated in tolerance of bacilli to a diverse set of stressors and antibiotics. Thus, development of Mtb biofilms appears to be associated with an enrichment of population, in which challenging growt...

Carbohydrate-based nanocarriers and their application to target macrophages and deliver antimicrobial agents.
Abstract Many deadly infections are produced by microorganisms capable of sustained survival in macrophages. This reduces exposure to chemotherapy, prevents immune detection, and is akin to criminals hiding in police stations. Therefore, the use of glyco-nanoparticles (GNPs) as carriers of therapeutic agents is a burgeoning field. Such an approach can enhance the penetration of drugs into macrophages with specific carbohydrate targeting molecules on the nanocarrier to interact with macrophage lectins. Carbohydrates are natural biological molecules and the key constituents in a large variety of biological events su...

Structure function insights into elusive Mycobacterium tuberculosis protein Rv1916.
This study reports recombinant production of Rv1916 in heterologous host E. coli BL21 (DE3) for structure function studies. The studies categorically demonstrate that akin to Mtb ICL1, recombinant Rv1916 also possess dual ICL and methylisocitrate lyase (MICL) activities in vitro. Based on in silico analysis, a putative function linked to secondary metabolite synthesis is assigned to unique mycobacterial domain IV.

Paradoxical reactions in ocular tuberculosis
AbstractParadoxical reactions following initiation of anti-tubercular therapy have been documented most often in extrapulmonary tuberculosis. A combination of factors such as delayed hypersensitivity, decreased suppressor mechanisms, and an increased response to mycobacterial antigens mediated by the host ’s immune system have been implicated in the development of these reactions. Similar worsening in patients with ocular tuberculosis while on treatment has been described. It is therefore important for the clinician to be aware of this occurrence, as prompt recognition and timely institution of cor ticosteroids and i...

Targeting innate immunity for tuberculosis vaccination
Vaccine development against tuberculosis (TB) is based on the induction of adaptive immune responses endowed with long-term memory against mycobacterial antigens. Memory B and T cells initiate a rapid and robust immune response upon encounter with Mycobacterium tuberculosis, thus achieving long-lasting protection against infection. Recent studies have shown, however, that innate immune cell populations such as myeloid cells and NK cells also undergo functional adaptation after infection or vaccination, a de facto innate immune memory that is also termed trained immunity. Experimental and epidemiological data have shown tha...

Novel furan coupled quinoline diamide hybrid scaffolds as potent antitubercular agents: Design, synthesis and molecular modelling.
CONCLUSION: The synthesized FQD derivatives exhibited moderate to good inhibition activity especially compounds 5f, 5b and 8a exhibited very good inhibition activity due to the presence of three different scaffolds, such as INH, phenyl ketobutyric acid and fluoroquinolines. Hybridized molecules might have multiple mode of action / inhibit more than one tubercular target and could pave way for novel drug discovery in the field of tuberculosis.

Uncovering Structural and Molecular Dynamics of ESAT-6: β2M Interaction: Asp53 of Human β2-Microglobulin Is Critical for the ESAT-6:β2M Complexation.

Docking-based high-throughput virtual screening followed by 16-point screening on microscale thermophoresis resulted in the identification of two potent inhibitors (SM09 and SM15) that mask the critical Met93 residue of ESAT-6 that is required for ESAT-6:β2M interaction and could rescue cell surface expression of β2...

Possible binding of piperine in Mycobacterium tuberculosis RNA-polymerase and rifampicin synergism.
Abstract The activity of rifampicin (RIF) and piperine (PIP) was evaluated at the relative transcript levels of 12 efflux pumps (EPs) and an additional mechanism was proposed behind the synergic interactions of PIP+RIF in Mycobacterium tuberculosis (Mtb). Autodock-v4.2.3 and Molegro-v6 programs were used to evaluate PIP binding in Mtb RNA polymerase (RNAP). A hypothesis has been raised that PIP interferes in Mtb growth through RNAP inhibition, differently from what was previously endorsed for EPs inhibition only.
