A high-content image-based drug screen of clinical compounds against cell transmission of adenovirus

Gerardo Turcatti, Fabien Kuttler

Human adenoviruses (HAdVs) are fatal to immuno-suppressed individuals, but no effective anti-HAdV therapy is available. Here, we present a novel image-based high-throughput screening (HTS) platform, which scores the full viral replication cycle from virus ...

Sulfonated Nanomaterials with Broad-Spectrum Antiviral Activity Extending beyond Heparan Sulfate-Dependent Viruses

Francesco Stellacci, Valeria Cagno, Matteo Gasbarri, Chiara Medaglia

Viral infections are among the main causes of death worldwide, and we lack antivirals for the majority of viruses. Heparin-like sulfated or sulfonated compounds have been known for decades for their ability to prevent infection by heparan sulfate proteogly ...

Broad-spectrum non-toxic antiviral nanoparticles with a virucidal inhibition mechanism

Francesco Stellacci, Paulo Henrique Jacob Silva, Ahmet Bekdemir, Valeria Cagno, Emma-Rose Janecek, Samuel Thomas Jones, Marie Mueller

Viral infections kill millions yearly. Available antiviral drugs are virus-specific and active against a limited panel of human pathogens. There are broad-spectrum substances that prevent the first step of virus–cell interaction by mimicking heparan sulfat ...

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 ...

An experimental evaluation of drug-induced mutational meltdown as an antiviral treatment strategy

Jeffrey David Jensen, Claudia Bank, Matthieu Foll, Sebastian Matuszewski, Hyunjin Shim

The rapid evolution of drug resistance remains a critical public health concern. The treatment of influenza A virus (IAV) has proven particularly challenging, due to the ability of the virus to develop resistance against current antivirals and vaccines. He ...

A modeling approach to estimate the solar disinfection of viral indicator organisms in waste stabilization ponds and surface waters

Tamar Kohn, Michael Jon Mattle

Sunlight is known to be a pertinent factor governing the infectivity of waterborne viruses in the environment. Sunlight inactivates viruses via endogenous inactivation (promoted by absorption of UVB sunlight by the virus) and exogenous processes (promoted ...

Polyvalent Side Chain Peptide-Synthetic Polymer Conjugates as HIV-1 Entry Inhibitors

Harm-Anton Klok, Maarten Danial

This report describes the synthesis and properties of a series of polyvalent side chain peptide synthetic polymer conjugates designed to block the CD4 binding site on gp120 and inhibit HIV-1 entry into a host cell. The peptide sequences in the conjugates a ...

On the replication of adeno-associated virus in the presence or absence of viral helper functions

Anika Ekrut

Adeno-associated virus (AAV) is a small non-enveloped virus and as a member of the parvovirus family, it contains a single stranded DNA genome. AAV's life cycle in vitro is strongly dependent not only on cellular factors but also on helper functions provid ...

Suppression of immediate-early viral gene expression by herpesvirus-coded microRNAs: Implications for latency

Jiri Vanicek

A quantitative algorithm was developed and applied to predict target genes of microRNAs encoded by herpesviruses. Although there is almost no conservation among microRNAs of different herpesvirus subfamilies, a common pattern of regulation emerged. The alg ...

Interfering residues narrow the spectrum of MLV restriction by human TRIM5alpha

Didier Trono, Priscilla Turelli, Séverine Reynard, Pierre Maillard

TRIM5alpha is a restriction factor that limits infection of human cells by so-called N- but not B- or NB-tropic strains of murine leukemia virus (MLV). Here, we performed a mutation-based functional analysis of TRIM5alpha-mediated MLV restriction. Our resu ...
