Loss of Bacterial Cell Pole Stabilization in Caulobacter crescentus Sensitizes to Outer Membrane Stress and Peptidoglycan-Directed Antibiotics

Gerardo Turcatti, Marc Chambon, Julien Bortoli Chapalay

Rod-shaped bacteria frequently localize proteins to one or both cellpoles in order to regulate processes such as chromosome replication or polar organ-elle development. However, the roles of polar factors in responses to extracellularstimuli have been gene ...

Boosting subdominant neutralizing antibody responses with a computationally designed epitope-focused immunogen

Bruno Emanuel Ferreira De Sousa Correia, Jaume Bonet Martinez, Pablo Gainza Cirauqui, Fabian Sesterhenn, Stéphane Rosset, Che Yang, Patricia Corthésy Henrioud, Sabrina Susan Vollers

Throughout the last several decades, vaccination has been key to prevent and eradicate infectious diseases. However, many pathogens (e.g., respiratory syncytial virus [RSV], influenza, dengue, and others) have resisted vaccine development efforts, largely ...

Gut microbial transformation of the dietary mutagen MeIQx may reduce exposure levels without altering intestinal transport

Julita Maria Stadnicka-Michalak

The mutagen and probable human carcinogen 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) is metabolized in the colon to 9-hydroxyl-2,7-dimethyl-7,9,10,11-tetrahydropyrimido[2',1':2,3]imidazo[4,5-f]quinoxaline (MeIQx-M1) by conjugation with microbial ...

Bile acids drive colonic secretion of glucagon-like-peptide 1 and peptide-YY in rodents

Kristina Schoonjans

A large number of glucagon-like-peptide-1(GLP-1)- and peptide-YY (PYY)-producing L cells are located in the colon, but little is known about their contribution to whole body metabolism. Since bile acids (BAs) increase GLP-1 and PYY release, and since BAs s ...

Absence of specific alternatively spliced exon of CD44 in macrophages prevents colitis

Ulrich Hoffmann, Riccardo Sabatini

CD44 is a transmembrane molecule appearing in numerous isoforms generated by insertions of alternatively spliced variant exons (CD44v) and having various binding partners. CD44v7 on T cells was proposed to promote colitis by preventing T-cell apoptosis. He ...

Using NanoSIMS coupled with microfluidics to visualize the early stages of coral infection by Vibrio coralliilyticus

Anders Meibom, Isabelle Domart-Coulon, Emma Mary Gibbin

Background: Global warming has triggered an increase in the prevalence and severity of coral disease, yet little is known about coral/pathogen interactions in the early stages of infection. The point of entry of the pathogen and the route that they take on ...

Interference of engineered nanomaterials in flow cytometry: A case study

Aurélie Walter

Nanotechnology is regarded as the enabling technology of the 21st century. However, only a relatively small number of nano-enabled medical and healthcare products finally made their way to the market. There are several reasons why such innovative approache ...

Risk Perception and Epidemics in Complex Computer Networks

Emanuele Massaro

We present a self-organised method for quickly obtaining the epidemic threshold of infective processes on networks. Starting from simple percolation models, we introduce the possibility that the effective infection probability is affected by the perception ...

Interbacterial predation as a strategy for DNA acquisition in naturally competent bacteria

Melanie Blokesch

Natural competence enables bacteria to take up exogenous DNA. The evolutionary function of natural competence remains controversial, as imported DNA can act as a source of substrates or can be integrated into the genome. Exogenous homologous DNA can also b ...
