Broad-spectrum Antiviral Nanoparticles

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 ...

Single particle maximum likelihood reconstruction from superresolution microscopy images

Suliana Manley, Julia Gunzenhäuser

Point localization superresolution microscopy enables fluorescently tagged molecules to be imaged beyond the optical diffraction limit, reaching single molecule localization precisions down to a few nanometers. For small objects whose sizes are few times t ...

Viruses at solid-water interfaces: A systematic assessment of interactions driving adsorption

Tamar Kohn, Meret Aeppli, Anne Thérèse Sigstam, Antonius Magdi Hakeem Armanious, Dominik Refardt

Adsorption to solid-water interfaces is a major process governing the fate of waterborne viruses in natural and engineered systems. The relative contributions of different interaction forces to adsorption and their dependence on the physicochemical propert ...

Insights into the Structure and Dynamics of Measles Virus Nucleocapsids by H-1-detected Solid-state NMR

David Lyndon Emsley

H-1-detected solid-state nuclear magnetic resonance (NMR) experiments are recorded on both intact and trypsin-cleaved sedimented measles virus (MeV) nucleocapsids under ultra-fast magic-angle spinning. High-resolution H-1,N-15-fingerprints allow probing th ...

On the cause of the tailing phenomenon during virus disinfection by chlorine dioxide

Tamar Kohn, Qingxia Zhong, Anne Thérèse Sigstam, Moritz Brennecke, Andreas Rohatschek

This study investigates the mechanisms underlying the deviation from Chick-Watson kinetics, namely a tailing curve, during the disinfection of viruses by chlorine dioxide (ClO2). Tailing has been previously reported, but is typically attributed to the deca ...

How Viruses Hijack the ERAD Tuning Machinery

Maurizio Molinari, Riccardo Bernasconi

An essential step during the intracellular life cycle of many positive-strand RNA viruses is the rearrangement of host cell membranes to generate membrane-bound replication platforms. For example, Nidovirales and Flaviviridae subvert the membrane of the en ...

Vaccinia Virus Entry Is Followed by Core Activation and Proteasome-Mediated Release of the Immunomodulatory Effector VH1 from Lateral Bodies

Henning Paul-Julius Stahlberg, Lucia Reh

Host cell entry of vaccinia virus, the prototypic poxvirus, involves a membrane fusion event delivering the viral core and two proteinaceous lateral bodies (LBs) into the cytosol. Uncoating of viral cores is poorly characterized, and the composition and fu ...

Subtle differences in virus composition affect disinfection kinetics and mechanisms

Tamar Kohn, Krista Rule Wigginton, Brian Pecson, Michele Cascella, Anne Thérèse Sigstam

Viral disinfection kinetics have been studied in depth, but the molecular-level inactivation mechanisms are not understood. Consequently, it is difficult to predict the disinfection behavior of non-culturable viruses, even when related, culturable viruses ...

UV radiation induces genome-mediated, site-specific cleavage in viral protein

Tamar Kohn, Yury Tsybin, Laure Menin, Krista Rule Wigginton, Michele Cascella, Hisham Ben Hamidane, Anne Thérèse Sigstam

Much research has been dedicated to understanding the molecular basis of UV damage to biomolecules, yet many questions remain regarding the specific pathways involved. Here we describe a genome-mediated mechanism that causes sitespecific virus protein clea ...

Virus Inactivation by Homogeneous and Heterogeneous Fenton-like Processes

Jessica Ivana Nieto Juarez

Human enteric viruses in water sources cause a great public health risk. Conventional disinfection treatments are not able to completely inactive viruses. However, advanced oxidation processes (AOPs) have recently been shown to effectively inactivate patho ...
