Polarly Localized EccE(1) Is Required for ESX-1 Function and Stabilization of ESX-1 Membrane Proteins in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Ming Zhang, Jérémie Piton, Paloma Julia Soler Arnedo

Mycobacterium tuberculosis is a slow-growing intracellular bacterium with the ability to induce host cell death and persist indefinitely in the human body. This pathogen uses the specialized ESX-1 secretion system to secrete virulence factors and potent im ...

Genomic and transcriptomic analysis of the streptomycin-dependent Mycobacterium tuberculosis strain 18b

Stewart Cole, Claudia Sala, Andrej Benjak, Ming Zhang, Swapna Uplekar, Jérémie Piton

Background: The ability of Mycobacterium tuberculosis to establish a latent infection (LTBI) in humans confounds the treatment of tuberculosis. Consequently, there is a need to discover new therapeutic agents that can kill M. tuberculosis both during activ ...

Bioluminescence for Assessing Drug Potency against Nonreplicating Mycobacterium tuberculosis

Stewart Cole, Neeraj Dhar, Claudia Sala, Ruben Hartkoorn, Ming Zhang, Benoit Lechartier, Anthony Vocat

Targeting dormant Mycobacterium tuberculosis represents a challenge to antituberculosis drug discovery programs. We previously reported and validated the use of the streptomycin (STR)-dependent M. tuberculosis 18b strain as a tool for assessing drug potenc ...

EspI regulates the ESX-1 secretion system in response to ATP levels in Mycobacterium tuberculosis

Stewart Cole, Neeraj Dhar, Claudia Sala, Ming Zhang, Jan Lars Rybniker, Jeffrey Chen

The function of EspI, a 70kDa protein in Mycobacterium tuberculosis, has remained unclear. Although EspI is encoded by a gene within the esx-1 locus, in this study we clarify previous conflicting results and show that EspI is not essential for ESX-1-mediat ...

The Phosphatidyl-myo-Inositol Mannosyltransferase PimA Is Essential for Mycobacterium tuberculosis Growth In Vitro and In Vivo

Stewart Cole, Neeraj Dhar, Claudia Sala, Ming Zhang, Gaëlle Séraphine Kolly, Naveen Kumar

The cell envelope of Mycobacterium tuberculosis contains glycans and lipids of peculiar structure that play prominent roles in the biology and pathogenesis of tuberculosis. Consequently, the chemical structure and biosynthesis of the cell wall have been in ...

In Vitro and In Vivo Activities of Three Oxazolidinones against Nonreplicating Mycobacterium tuberculosis

Stewart Cole, Neeraj Dhar, Claudia Sala, Ming Zhang, Anthony Vocat

Oxazolidinones represent a new class of antituberculosis drugs that exert their function by inhibiting protein synthesis. Here, we compared the activities of three oxazolidinones, linezolid, PNU-100480, and AZD5847, against latent tuberculosis using a simp ...

Towards a new combination therapy for tuberculosis with next generation benzothiazinones

Paul Joseph Dyson, Stewart Cole, Florence Pojer, Ruben Hartkoorn, Ming Zhang, Joao Pedro De Almeida Neres, Anthony Vocat, Benoit Lechartier, Thierry Buclin

The benzothiazinone lead compound, BTZ043, kills Mycobacterium tuberculosis by inhibiting the essential flavo-enzyme DprE1, decaprenylphosphoryl-beta-D-ribose 2-epimerase. Here, we synthesized a new series of piperazine-containing benzothiazinones (PBTZ) a ...

Anticytolytic Screen Identifies Inhibitors of Mycobacterial Virulence Protein Secretion

Stewart Cole, Claudia Sala, Ruben Hartkoorn, Andrej Benjak, Ming Zhang, Anthony Vocat, Jan Lars Rybniker, Jeffrey Chen, Edina Rita Székely

Mycobacterium tuberculosis (Mtb) requires protein secretion systems like ESX-1 for intracellular survival and virulence. The major virulence determinant and ESX-1 substrate, EsxA, arrests phagosome maturation and lyses cell membranes, resulting in tissue d ...

Phenotypic Profiling of Mycobacterium tuberculosis EspA Point Mutants Reveals that Blockage of ESAT-6 and CFP-10 Secretion In Vitro Does Not Always Correlate with Attenuation of Virulence

Stewart Cole, Neeraj Dhar, Florence Pojer, Ming Zhang, Jan Lars Rybniker, Jeffrey Chen, Anna De Graff Tischler

The EspA protein of Mycobacterium tuberculosis is essential for the type VII ESX-1 protein secretion apparatus, which delivers the principal virulence factors ESAT-6 and CFP-10. In this study, site-directed mutagenesis of EspA was performed to elucidate it ...
