Viral Transfer and Inactivation through Zooplankton Trophic Interactions

Tamar Kohn, Virginie Bachmann, Xavier Fernandez Cassi, Margot Ninon Lauren Olive

Waterborne viruses are responsible for numerous diseases and are abundant in aquatic systems. Understanding the fate of viruses in natural systems has important implications for human health. This research quantifies the uptake of bacteriophage T4 and the ...

Dynamic Nuclear Polarization Magic-Angle Spinning Nuclear Magnetic Resonance Combined with Molecular Dynamics Simulations Permits Detection of Order and Disorder in Viral Assemblies

David Lyndon Emsley, Marc Anthony Caporini

We report dynamic nuclear polarization (DNP)-enhanced magic-angle spinning (MAS) NMR spectroscopy in viral capsids from HIV-1 and bacteriophage AP205. Viruses regulate their life cycles and infectivity through modulation of their structures and dynamics. W ...

Differences in viral disinfection mechanisms as revealed by quantitative transfection of Echovirus 11 genomes

Urs von Gunten, Tamar Kohn, Jason Robert Torrey

Virus inactivation mechanisms can be elucidated by methods which measure the loss of specific virus functionality (e.g., host attachment, genome internalization, genome replication). Genome functionality is frequently assessed by PCR-based methods, which a ...

An Atomistic Look into Bio-inspired Nanoparticles and their Molecular Interactions with Cells

Francesco Stellacci, Alke Fink, Pablo Campomanes Ramos, Stefano Vanni

Nanoparticles (NPs) have sizes that approach those of pathogens and they can interact with the membranes of eukaryotic cells in an analogous fashion. Typically, NPs are taken up by the cell via the plasma membrane by receptor-mediated processes and subsequ ...

E-coli-MS2 bacteriophage interactions during solar disinfection of wastewater and the subsequent post-irradiation period

César Pulgarin, Anna Carratala Ripolles, Stefanos Giannakis, Margaux Océane Voumard

In this study, the effect of MS2 bacteriophage on the inactivation of its Escherichia coli host was evaluated in an effort to recreate some the main factors governing solar disinfection of wastewater (namely microbial growth, infection, photonic flux). As ...

Patchy Amphiphilic Dendrimers Bind Adenovirus and Control Its Host Interactions and in Vivo Distribution

Francesco Stellacci, Weina Liu

The surface of proteins is heterogeneous with sophisticated but precise hydrophobic and hydrophilic patches, which is essential for their diverse biological functions. To emulate such distinct surface patterns on macromolecules, we used rigid spherical syn ...

EspL is essential for virulence and stabilizes EspE, EspF and EspH levels in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Andrej Benjak, Nina Theres Odermatt, Paloma Julia Soler Arnedo, Sofia Ulrika Magnusdotter Von Schultz

The ESX-1, type VII, secretion system represents the major virulence determinant of Mycobacterium tuberculosis, one of the most successful intracellular pathogens. Here, by combining genetic and high-throughput approaches, we show that EspL, a protein of 1 ...

Palmitoylation mediates membrane association of hepatitis E virus ORF3 protein and is required for infectious particle secretion

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Johann Mauron, Joël Oppliger, Maxime Matter, Noémie Oechslin

Hepatitis E virus (HEV) is a positive-strand RNA virus encoding 3 open reading frames (ORF). HEV ORF3 protein is a small, hitherto poorly characterized protein involved in viral particle secretion and possibly other functions. Here, we show that HEV ORF3 p ...

High-speed photothermal off-resonance atomic force microscopy reveals assembly routes of centriolar scaffold protein SAS-6

Pierre Gönczy, Adrian Pascal Nievergelt, Georg Fantner, Niccolo Banterle, Santiago Harald Andany

The self-assembly of protein complexes is at the core of many fundamental biological processes1, ranging from the polymerization of cytoskeletal elements, such as microtubules2, to viral capsid formation and organelle assembly3. To reach a comprehensive un ...

Broad-spectrum Antiviral Nanoparticles : a morphological CryoEM Study on the Interaction of Nanoparticles and Viruses

Marie Müller

Viral infections affect millions of people every year, yet broad-spectrum virucidal therapies are not available. Antiviral substances in current use act on specific viral mechanisms against only a small number of viruses. Virustatic materials interfere wit ...
