In situ detection of multitarget impurities on contact lens by electrochemical scanning probe

Fang Liu, Tzu-En Lin, Yingdi Zhu

Identifying multitarget impurities on contact lenses is challenging because traditional methods such as polymerase chain reaction cannot be used on the unknown target. Other sampling methods often require expensive antibodies or dyes. Therefore, this resea ...

High-content, arrayed compound screens with rhinovirus, influenza A virus and herpes simplex virus infections

Gerardo Turcatti, Fabien Kuttler

Viruses are genetically and structurally diverse, and outnumber cells by orders of magnitude. They can cause acute and chronic infections, suppress, or exacerbate immunity, or dysregulate survival and growth of cells. To identify chemical agents with pro- ...

Polyanionic Amphiphilic Dendritic Polyglycerols as Broad-Spectrum Viral Inhibitors with a Virucidal Mechanism

Francesco Stellacci, Matteo Gasbarri, Valeria Cagno

Heparin has been known to be a broad-spectrum inhibitor of viral infection for almost 70 years, and it has been used as a medication for almost 90 years due to its anticoagulant effect. This nontoxic biocompatible polymer efficiently binds to many types of ...

Novel broad-spectrum virucidal antivirals

Matteo Gasbarri

The current COVID-19 pandemic has showed the threats that viruses can cause to the whole world. Over 200 million infections and over 4.5 million deaths and enormous socio-economic impact were the output of the emergence of a single new pathogen: SARS-CoV-2 ...

Highly Potent Host-Specific Small-Molecule Inhibitor of Paramyxovirus and Pneumovirus Replication with High Resistance Barrier

Gerardo Turcatti, Marc Chambon, Damiano Banfi, Jonathan Patrice Vesin

Multiple enveloped RNA viruses of the family Paramyxoviridae and Pneumoviridae, like measles virus (MeV), Nipah virus (NiV), canine distemper virus (CDV), or respiratory syncytial virus (RSV), are of high clinical relevance. Each year a huge number of live ...

Modified cyclodextrins as broad-spectrum antivirals

Francesco Stellacci, Natalia Gasilova, Daniel Ortiz Trujillo, Matteo Gasbarri, Valeria Cagno, Samuel Thomas Jones, Matej Janecek

Viral infections kill millions of people and new antivirals are needed. Nontoxic drugs that irreversibly inhibit viruses (virucidal) are postulated to be ideal. Unfortunately, all virucidal molecules described to date are cytotoxic. We recently developed n ...

Multi-sulfonated ligands on gold nanoparticles as virucidal antiviral for Dengue virus

Francesco Stellacci, Quy Ong Khac, Özgün Kocabiyik

Dengue virus (DENV) causes 390 million infections per year. Infections can be asymptomatic or range from mild fever to severe haemorrhagic fever and shock syndrome. Currently, no effective antivirals or safe universal vaccine is available. In the present w ...

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

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 ...

Corneal epithelial stem cells and their niche at a glance

Freddy Radtke, Craig Nowell

The corneal epitheliumacts as a protective barrier on the anterior ocular surface and is essential for maintaining transparency of the cornea and thus visual acuity. During both homeostasis and repair, the corneal epithelium is maintained by self-renewing ...

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 ...

EYE GAZE TRACKING SYSTEM AND METHOD

Jean-Philippe Thiran, Nuri Murat Arar

An eye gaze tracking system is disclosed. The system includes a gaze data acquisition system including a plurality of light sources and a plurality of image sensors. The plurality of light sources are arranged to emit light to a head of the user, and the p ...

MicroRNA Profile in CD8+T-Lymphocytes from HIV-Infected Individuals: Relationship with Antiviral Immune Response and Disease Progression

Evaristo Jose Planet Letschert

Background The relationship between host microRNAs (miRNA), viral control and immune response has not yet been elucidated in the field of HIV. The aim of this study was to assess the differential miRNA profile in CD8+ T-cells between HIV-infected individua ...

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

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 ...

Corneal epithelial cell fate is maintained during repair by Notch1 signaling via the regulation of vitamin A metabolism

Freddy Radtke, Yann Barrandon

Integrity and preservation of a transparent cornea are essential for good vision. The corneal epithelium is stratified and nonkeratinized and is maintained and repaired by corneal stem cells. Here we demonstrate that Notch1 signaling is essential for cell ...

Interfering residues narrow the spectrum of MLV restriction by human TRIM5alpha

Didier Trono, Priscilla Turelli, Séverine Reynard

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 ...
