Mycobacterium tuberculosis Resists Stress by Regulating PE19 Expression

Mycobacterium tuberculosis requires the phosphate-sensing signal transduction system Pst/SenX3-RegX3 to resist host immune responses. A Delta pstA1 mutant lacking a Pst phosphate uptake system component is hypersensitive to diverse stress conditions in vit ...

Fibronectin EDA and CpG synergize to enhance antigen-specific Th1 and cytotoxic responses

Jeffrey Alan Hubbell, Melody Swartz, Alexandre de Titta, Ziad Julier, Eleonora Simeoni, Alizée Jéléna Grimm

Subunit vaccines, employing purified protein antigens rather than intact pathogens, require the addition of adjuvants for enhanced immunogenicity with a correct balance between strong activation of the immune system and low toxicity. Here we show that the ...

GtrA Protein Rv3789 Is Required for Arabinosylation of Arabinogalactan in Mycobacterium tuberculosis

Gaëlle Séraphine Kolly, Stewart Cole, Claudia Sala, Matteo Dal Peraro, Mahé Cécile Raccaud, Raju Mukherjee, Luciano Andres Abriata

Mycobacterium tuberculosis possesses a thick and highly hydrophobic cell wall principally composed of a mycolyl-arabinogalactan-peptidoglycan complex, which is critical for survival and virulence. DprE1 is a well-characterized component of decaprenyl-phosp ...

Mycobacterium tuberculosis Differentially Activates cGAS- and Inflammasome-Dependent Intracellular Immune Responses through ESX-1

Sonia Garcia Perin, Stewart Cole, Claudia Sala, Jan Lars Rybniker, Ye Lou, Andrea Ablasser, Muhammet Fatih Gülen

Cytosolic detection of microbial products is essential for the initiation of an innate immune response against intracellular pathogens such as Mycobacterium tuberculosis (Mtb). During Mtb infection of macrophages, activation of cytosolic surveillance pathw ...

Stress and Host Immunity Amplify Mycobacterium tuberculosis Phenotypic Heterogeneity and Induce Nongrowing Metabolically Active Forms

John McKinney, Neeraj Dhar, Giulia Manina

Nonreplicating and metabolically quiescent bacteria are implicated in latent tuberculosis infections and relapses following "sterilizing" chemotherapy. However, evidence linking bacterial dormancy and persistence in vivo is largely inconclusive. Here we me ...

Anticytolytic Screen Identifies Inhibitors of Mycobacterial Virulence Protein Secretion

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

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 ...

Delayed bactericidal response of Mycobacterium tuberculosis to bedaquiline involves remodelling of bacterial metabolism

John McKinney, Neeraj Dhar, Muhittin Emre Özdemir, Ping Lu

Bedaquiline (BDQ), an ATP synthase inhibitor, is the first drug to be approved for treatment of multidrug-resistant tuberculosis in decades. Though BDQ has shown excellent efficacy in clinical trials, its early bactericidal activity during the first week o ...

Peptide-Based Vaccinology: Experimental and Computational Approaches to Target Hypervariable Viruses through the Fine Characterization of Protective Epitopes Recognized by Monoclonal Antibodies and the Identification of T-Cell-Activating Peptides

Matteo Dal Peraro, Matteo Castelli

Defining immunogenic domains of viral proteins capable of eliciting a protective immune response is crucial in the development of novel epitope-based prophylactic strategies. This is particularly important for the selective targeting of conserved regions s ...

Improving Immunogenicity of Subunit Vaccines Using Nanocarrier Systems

Armando Stano

New generation vaccines, which are subunit vaccines, have considerably improved safety profiles, but are often poorly immunogenic, especially when administered through mucosal routes. Also, the diversity of the mechanisms of action of infectious pathogens ...

A Point Mutation in cycA Partially Contributes to the D-cycloserine Resistance Trait of Mycobacterium bovis BCG Vaccine Strains

Stewart Cole, Jeffrey Chen, Swapna Uplekar

In mycobacteria, CycA a D-serine, L-and D-alanine, and glycine transporter also functions in the uptake of D-cycloserine, an important second-line anti-tubercular drug. A single nucleotide polymorphism identified in the cycA gene of BCG was hypothesized to ...

Genomics and transcriptomics of the Mycobacterium tuberculosis complex

Swapna Uplekar

The goal of eliminating tuberculosis (TB) by 2050 depends on the development of improved TB diagnostics, drugs and vaccines. Advances in these areas require a deep understanding of the disease and its causative agent, Mycobacterium tuberculosis (M. tb). My ...

Dendritic cell activation and T cell priming with adjuvant- and antigen-loaded oxidation-sensitive polymersomes

Jeffrey Alan Hubbell, Melody Swartz, Armando Stano

While current subunit vaccines successfully induce humoral immune responses, a need exists for vaccine strategies to elicit strong cell-mediated immunity to address diseases such as cancer and chronic viral infection. Polymersomes are stable vesicles compo ...
