S-acylation and lipid exchange at the ER-Golgi membrane contact sites regulate pathogen entry in human cells

Cells have evolved endocytic pathways to internalize different molecules, to regulate intra-cellular communication and their interaction with external environment. Pathogens have co-evolved with cells to exploit these processes for infections. In particula ...

Stability of influenza A virus in droplets and aerosols is heightened by the presence of commensal respiratory bacteria

Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler, Htet Kyi Wynn, Céline Terrettaz, Laura José Costa Henriques

Aerosol transmission remains a major challenge for control of respiratory viruses, particularly those causing recurrent epidemics, like influenza A virus (IAV). These viruses are rarely expelled alone, but instead are embedded in a consortium of microorgan ...

Harnessing the Membrane Translocation Properties of AB Toxins for Therapeutic Applications

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva, Numa Piot

Over the last few decades, proteins and peptides have become increasingly more common as FDA-approved drugs, despite their inefficient delivery due to their inability to cross the plasma membrane. In this context, bacterial two-component systems, termed AB ...

Retention of E. coli and water on the skin after liquid contact

Tamar Kohn, Timothy R. Julian

The frequent contact people have with liquids containing pathogenic microorganisms provides opportunities for disease transmission. In this work, we quantified the transfer of bacteria—using E. coli as a model- from liquid to skin, estimated liquid retenti ...

Anthrax toxin requires ZDHHC5-mediated palmitoylation of its surface-processing host enzymes

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva

The protein acyl transferase ZDHHC5 was recently proposed to regulate trafficking in the endocytic pathway. Therefore, we explored the function of this enzyme in controlling the action of bacterial toxins. We found that ZDHHC5 activity is required for two ...

The Ins and Outs of Anthrax Toxin

Françoise Gisou van der Goot Grunberg

Anthrax is a severe, although rather rare, infectious disease that is caused by the Gram-positive, spore-forming bacterium Bacillus anthracis. The infectious form is the spore and the major virulence factors of the bacterium are its poly-gamma-D-glutamic a ...

Folding and Endocytosis of Anthrax Toxin Receptors

Sarah Elisabeth Sandoz

Bacillus anthracis is the causative agent of the infectious disease anthrax. The disease is caused after taking up the spores by either inhalation, ingestion or through skin lesion. They then germinate inside the body and start secreting the tripartite ant ...

Variability in DPA and calcium content in the spores of Clostridium species

Rizlan Bernier-Latmani, Barbora Bártová, Cornelia List, Jan Jamroskovic, Zuzana Chromiková

Spores of a number of clostridia' species, and their resistance to thermal treatment is a major concern for the food industry. Spore resistance to wet heat is related to the level of spore hydration, which is inversely correlated with the content of calciu ...

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

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

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 ...

Assessing essentiality of transketolase in Mycobacterium tuberculosis using an inducible protein degradation system

Stewart Cole, Claudia Sala, Anthony Vocat, Gaëlle Séraphine Kolly

Improved genetic tools are required to identify new drug targets in Mycobacterium tuberculosis. To this aim, genetic approaches, targeting either transcription and/or protein degradation, have been developed to appraise gene essentiality and to test the im ...

Hijacking Multivesicular Bodies Enables Long-Term and Exosome-Mediated Long-Distance Action of Anthrax Toxin

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Lucia Brandi

Anthrax lethal toxin is a classical AB toxin comprised of two components: protective antigen (PA) and lethal factor (LF). Here, we show that following assembly and endocytosis, PA forms a channel that translocates LF, not only into the cytosol, but also in ...
