Monitoring Tuberculosis Drug Activity in Live Animals by Using Near-Infrared Fluorescence Imaging

Stewart Cole, Raphael Christopher Sommer

Worldwide, tuberculosis (TB) is the leading cause of death due to infection with a single pathogenic agent, Mycobacterium tuberculosis. In the absence of an effective vaccine, new, more powerful antibiotics are required to halt the growing spread of multid ...

Innovative Tools and in vivo Methods for Tuberculosis Drug Discovery and Development

Raphael Christopher Sommer

Worldwide, tuberculosis (TB) is the leading cause of death due to a single infectious agent, claiming 1.6 million human lives and causing >10 million new cases in 2017 alone, mostly in low-income regions. The intracellular pathogen Mycobacterium tuberculos ...

Vitamin B12 deficiency and impaired expression of amnionless during aging

Laurence Goulet, Albano António De Abreu E Presa De Castro E Sousa, Sonia Karaz, Alice Pannerec

Background Physical frailty and loss of mobility in elderly individuals lead to reduced independence, quality of life, and increased mortality. Vitamin B12 deficiency has been linked to several age-related chronic diseases, including in the musculo-skeleta ...

Functional characterization of the virulence determinant ESX-1 from Mycobacterium tuberculosis

Paloma Julia Soler Arnedo

Tuberculosis (TB) is a chronic infectious disease that mainly affects the lungs and causes extensive human morbidity and mortality. It results from infection with Mycobacterium tuberculosis, a slow-growing intracellular pathogen that can replicate and surv ...

Genetics of human susceptibility to active and latent tuberculosis: present knowledge and future perspectives

Jacques Fellay, Nimisha Chaturvedi

Tuberculosis is an ancient human disease, estimated to have originated and evolved over thousands of years alongside modern human populations. Despite considerable advances in disease control, tuberculosis remains one of the world's deadliest communicable ...

Arylvinylpiperazine Amides, a New Class of Potent Inhibitors Targeting QcrB of Mycobacterium tuberculosis

Stewart Cole, Raphael Christopher Sommer, Shi-Yan Caroline Foo, Anthony Vocat, Andrej Benjak, Jérémie Piton, Andréanne Lupien

New drugs are needed to control the current tuberculosis (TB) pandemic caused by infection with Mycobacterium tuberculosis. We report here on our work with AX-35, an arylvinylpiperazine amide, and four related analogs, which are potent antitubercular agent ...

Antimicrobial resistance in leprosy: results of the first prospective open survey conducted by a WHO surveillance network for the period 2009-15

Stewart Cole

Objectives: Antimicrobial resistance (AMR) is a priority for surveillance in bacterial infections. For leprosy, AMR has not been assessed because Mycobacterium leprae does not grow in vitro. We aim to obtain AMR data using molecular detection of resistance ...

A multitarget approach to drug discovery inhibiting Mycobacterium tuberculosis PyrG and PanK

Stewart Cole

Mycobacterium tuberculosis, the etiological agent of the infectious disease tuberculosis, kills approximately 1.5 million people annually, while the spread of multidrug-resistant strains is of great global concern. Thus, continuous efforts to identify new ...

EspL is essential for virulence and stabilizes EspE, EspF and EspH levels in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Andrej Benjak, Nina Theres Odermatt, Sofia Ulrika Magnusdotter Von Schultz, Paloma Julia Soler Arnedo

The ESX-1, type VII, secretion system represents the major virulence determinant of Mycobacterium tuberculosis, one of the most successful intracellular pathogens. Here, by combining genetic and high-throughput approaches, we show that EspL, a protein of 1 ...

More Medicines for Tuberculosis: Fuelling Drug Discovery against Mycobacterium tuberculosis

Shi-Yan Caroline Foo

Tuberculosis (TB), whose etiological agent is Mycobacterium tuberculosis (M. tuberculosis), has plagued humanity since antiquity. Even with chemotherapy available today, TB is the leading cause of death due to an infectious disease. Modern day factors, suc ...

Deciphering the molecular basis of mycobacteria and lipoglycan recognition by the C-type lectin Dectin-2

Alexiane Clara Decout

Dectin-2 is a C-type lectin involved in the recognition of several pathogens such as Aspergillus fumigatus, Candida albicans, Schistosoma mansonii, and Mycobacterium tuberculosis that triggers Th17 immune responses. Identifying pathogen ligands and underst ...

Structure-Based Drug Design and Characterization of Sulfonyl-Piperazine Benzothiazinone Inhibitors of DprE1 from Mycobacterium tuberculosis

Stewart Cole, Shi-Yan Caroline Foo, Anthony Vocat, Jérémie Piton, Andréanne Lupien

Macozinone (MCZ) is a tuberculosis (TB) drug candidate that specifically targets the essential flavoenzyme DprE1, thereby blocking synthesis of the cell wall precursor decaprenyl phosphoarabinose (DPA) and provoking lysis of Mycobacterium tuberculosis. As ...
