Atomic-Scale Description of Interfaces between Antigen and Aluminum-Based Adjuvants Used in Vaccines by Dynamic Nuclear Polarization (DNP) Enhanced NMR Spectroscopy

Federico Maria Paruzzo, Jasmine Viger-Gravel

The addition of aluminum-based adjuvants in vaccines enhances the immune response to antigens. The strength of antigen adsorption on adjuvant gels is known to modulate vaccine efficacy. However, a detailed understanding of the mechanisms of interaction bet ...

Keep calm and carry on vaccinating: Is anti-vaccination sentiment contributing to declining vaccine coverage in England?

Marcel Salathé, Martin Mathias Müller

Background: In England, coverage for childhood vaccines have decreased since 2012/13 in the context of an increasingly visible anti-vaccination discourse. We determined whether anti-vaccination sentiment is the likely cause of this decline in coverage. Met ...

Evaluation of oxidation-sensitive polymersomes as vaccine nanocarriers to enhance humoral responses against arenavirus envelope glycoproteins

Clara Galan Navarro

Vaccines currently represent one of the most effective means to control and prevent infectious diseases affecting humans and animals and have dramatically improved public health, quality of life, and life expectancy. Over the last years several conceptual ...

Virucidal nanomaterials against influenza

Özgün Kocabiyik

Influenza affects millions of people in all parts of the world. The fact that influenza virus can spread through air increases the chance of influenza outbreaks. There are 3 to 5 million severe cases of influenza resulting in 290,000 to 650,000 deaths ever ...

Critical dynamics in population vaccinating behavior

Marcel Salathé, Sharada Prasanna Mohanty

Vaccine refusal can lead to renewed outbreaks of previously eliminated diseases and even delay global eradication. Vaccinating decisions exemplify a complex, coupled system where vaccinating behavior and disease dynamics influence one another. Such systems ...

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 ...

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 ...

On machine learning force fields for metallic nanoparticles

Kevin Rossi

Machine learning algorithms have recently emerged as a tool to generate force fields which display accuracies approaching the ones of the ab-initio calculations they are trained on, but are much faster to compute. The enhanced computational speed of machin ...

Protein engineering approaches for direct antigen targeting in CD8+ T cell inducing vaccines

Vasiliki Panagiotou

Effective vaccine design and public vaccination programs have led to the eradication of several diseases and protected millions of people from deadly infections. However, intracellular infections remain a challenge and their eradication requires the activa ...

Engineering nanoparticle-based vaccines: Implications for the quality of humoral and cellular immunity

Marcela Rincón-Restrepo

Vaccination is undoubtedly a major success in modern medicine. Yet, today there are pathogens for which no licensed or fully protective vaccines have been created. Development of vaccines based on subunit components has proven to be a safe and cost effecti ...

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 ...

Contact angle and adsorption energies of nanoparticles at the air-liquid interface determined by neutron reflectivity and molecular dynamics

Francesco Stellacci, Javier Reguera Gomez, Mauro Moglianetti

Understanding how nanomaterials interact with interfaces is essential to control their self-assembly as well as their optical, electronic, and catalytic properties. We present here an experimental approach based on neutron reflectivity (NR) that allows the ...

Oxidation-sensitive polymersomes as vaccine nanocarriers enhance humoral responses against Lassa virus envelope glycoprotein

Jeffrey Alan Hubbell, Melody Swartz, Sachiko Hirosue, Marcela Rincón-Restrepo, Clara Galan Navarro

Lassa virus (LASV) causes severe hemorrhagic fever with high mortality, yet no vaccine currently exists. Antibodies targeting viral attachment proteins are crucial for protection against many viral infections. However, the envelope glycoprotein (GP) 1 of L ...
