Researchers find mechanism involved in novel drug design with potential to treat tuberculosis

(Instituto de Medicina Molecular) Portuguese researchers successfully used a pioneer method to chemically modify a protein's components with potential medical applications and an impact in the fight against tuberculosis.

Conclusions: We found that two SNPs are associated with increased PTB risk and three SNPs decreased PTB risk in the Chinese Tibetan population. Our findings demonstrate an association between TLR2 and TLR4 polymorphisms and PTB. PMID: 29348888 [PubMed]

Authors: Pan L, Wei N, Jia H, Gao M, Chen X, Wei R, Sun Q, Gu S, Du B, Xing A, Zhang Z Abstract To better understand the host immune response involved in the progression from latent tuberculosis infection (LTBI) to active tuberculosis (TB) and identify the potential signatures for discriminating TB from LTBI, we performed a genome-wide transcriptional profile of Mycobacterium tuberculosis (M.TB)-specific antigens-stimulated peripheral blood mononuclear cells (PBMCs) from patients with TB, LTBI individuals and healthy controls (HCs). A total of 209 and 234 differentially expressed genes were detected in TB vs. LTBI ...

Abstract The virulence of tuberculosis infections resistant to conventional combination drug regimens cries for the design of potent fluoroquinolone compounds to be used as second line antimycobacterial chemotherapeutics. One of the most effective in silico methods is combinatorial design and high throughput screening by a ligand-based pharmacophore prior to experiment. The combinatorial design of a series of 3850 fluoroquinolone and isothiazoloquinolone compounds was then screened virtually by applying a topological descriptor based quantitative structure activity relationship (QSAR) for predicting highly active ...

CONCLUSION: RBT has fewer drug-drug interactions than rifampin and should be preferentially used for the treatment of tuberculosis in transplant patients treated with CsA. Close monitoring of CsA blood concentration during RBT therapy minimized the risk of under- or over-immunosuppression in a cardiac transplant patient.

Abstract Alpha-methylacyl-CoA racemase (AMACR) catalyzes the β-oxidation of fatty acids and is overexpressed in carcinomas in various organs, while its inactivation results in the inhibition of cancer growth. In the present study, we prepared and characterized 20 different mouse monoclonal antibodies against human AMACR. In the course of biopanning of a phage peptide commercial library against in-house prepared 6H9 and 2A5, and commercial 13H4 antibodies, 10 phage mimotopes recognized by each type of the antibody were selected. Using the program Pepitope and the crystal structure of AMACR from Mycobacterium t...

AbstractMycobacterium tuberculosis (M.tuberculosis) invading and activating microglia causes the most serious subtypes of tuberculosis called tubercular meningitis. However, the developmental process of tubercular meningitis, especially the early phase, is poorly understood due to lacking well-established and well-accepted visible models in vitro and in vivo. Here, consistent with one recent report, we foundMycobacterium marinum (M. marinum) invade the zebrafish brain and subsequently cause granuloma-like structures. We further showed thatM.marinum, which shares similar characteristics withM.tuberculosis, can invade microg...

Abstract: With the resurgence of tuberculosis (TB), it is imperative that healthcare providers have the necessary skills to manage the specialized issues of prevention, recognition, and treatment of TB. The case study in this article illustrates these skills for NPs and other advanced practice providers.

Abstract Mycobacterium tuberculosis, the causative agent of tuberculosis is now causing death of more than 10 million people. Because of the development of drug-resistant TB, drug delivery to the infected site through nanoparticle had been studied for long time. Nanoparticles indicate different sorts of association with the natural particles of the body. Nanoparticles can be used as controlled or specific drug delivery system. It can be through temporal controlled or can be distribution controlled. Glucose polymer-based nanoparticles might play an important role as drug delivery system in case of targeted drug del...
