High-resolution imaging and analysis of the intestinal bacterial load of Caenorhabditis elegans during early adulthood

We study the presence within the worm Caenorhabditis elegans (C. elegans) of a fluorescent strain of the worm's bacterial food (Escherichia coli (E. coli) OP50) during early adulthood. Use of a microfluidic chip based on a thin glass coverslip substrate al ...

Mechanism ofcyclic beta-glucan export by ABC transporter Cgt of Brucella

Henning Paul-Julius Stahlberg, Dongchun Ni, Na Wu

Polysaccharides play critical roles in bacteria, including the formation of protective capsules and biofilms and establishing specific host cell interactions. Their transport across membranes is often mediated by ATP-binding cassette (ABC) transporters, wh ...

The molecular treasure box of environmental Vibrio cholerae strains

Natalia Carolina Drebes Dorr

Cholera pandemics have been affecting humankind for centuries and are still considered a major public health problem, especially in regions around the world with poor access to clean water and sanitation. Cholera pandemics are caused by a specific lineage ...

Harnessing the Membrane Translocation Properties of AB Toxins for Therapeutic Applications

Françoise Gisou van der Goot Grunberg

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 ...

Comparison of chitin‐induced natural transformation in pandemic Vibrio cholerae O1 El Tor strains

Melanie Blokesch, Sandrine Stutzmann

The human pathogen Vibrio cholerae serves as a model organism for many important processes ranging from pathogenesis to natural transformation, which has been extensively studied in this bacterium. Previous work has deciphered important regulatory circuits ...

Mammalian membrane trafficking as seen through the lens of bacterial toxins

Françoise Gisou van der Goot Grunberg, Francisco De Magalhães Sarmento R De Mesquita, Oksana Andrei Sergeeva

A fundamental question of eukaryotic cell biology is how membrane organelles are organised and interact with each other. Cell biologists address these questions by characterising the structural features of membrane compartments and the mechanisms that coor ...

Intracellular bacteria engage a STING-TBK1-MVB12b pathway to enable paracrine cGAS-STING signalling

Andrea Ablasser, Bing Zhang, Alix Martin, Ensieh Farahani

The innate immune system is crucial for eventual control of infections, but may also contribute to pathology. Listeria monocytogenes is an intracellular Gram-positive bacteria and a major cause of food-borne disease. However, important knowledge on the int ...

Vibrio cholerae filamentation promotes chitin surface attachment at the expense of competition in biofilms

Alexandre Louis André Persat

Collective behavior in spatially structured groups, or biofilms, is the norm among microbes in their natural environments. Though biofilm formation has been studied for decades, tracing the mechanistic and ecological links between individual cell morpholog ...

Characterization of Efficiency and Mechanisms of Cold Atmospheric Pressure Plasma Decontamination of Seeds for Sprout Production

Alexandra Waskow

The consumption of fresh fruit and vegetable products has strongly increased during the past few decades. However, inherent to all minimally processed products is the short shelf life, and the risk of foodborne diseases, which have been increasingly relate ...
