Stability of influenza A virus in droplets and aerosols is heightened by the presence of commensal respiratory bacteria
Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler, Htet Kyi Wynn, Céline Terrettaz, Laura José Costa Henriques, Daniel Scott Nolan, Marta Augugliaro
Aerosol transmission remains a major challenge for control of respiratory viruses, particularly those causing recurrent epidemics, like influenza A virus (IAV). These viruses are rarely expelled alone, but instead are embedded in a consortium of microorgan ...
2024Inactivation of influenza A virus in expiratory droplets and aerosol particles and the associated physicochemical drivers
Influenza is an infectious respiratory illness caused by influenza viruses. Every year, it causes up to one billion cases of disease worldwide. Despite its high disease burden, the transmission pathway of influenza remains subject to debate. There is incre ...
EPFL2024Ligand concentration determines antiviral efficacy of silica multivalent nanoparticles
Francesco Stellacci, Paulo Henrique Jacob Silva, Quy Ong Khac, Xufeng Xu, Rémi Andréa La Polla, Heyun Wang
We have learned from the recent COVID-19 pandemic that the emergence of a new virus can quickly become a global health burden and kill millions of lives. Antiviral drugs are essential in our fight against viral diseases, but most of them are virus-specific ...
San Diego2023Effect of Matrix Composition and Thermodynamic Properties on Virus Persistence in Respiratory Droplets
Athanasios Nenes, Tamar Kohn, Aline Laetitia Schaub, Shannon Christa David, Laura José Costa Henriques
It is now well-established that respiratory viruses can be transmitted by the airborne route, yet the parameters modulating the infectivity of viruses in aerosol particles are poorly understood. Through a combined experimental and computational approach, w ...
2023Viral Genetic Determinants of Prolonged Respiratory Syncytial Virus Infection Among Infants in a Healthy Term Birth Cohort
Jacques Fellay, Zhi Ming Xu, Dylan Lawless, Thomas Junier
Background. Respiratory syncytial virus (RSV) is associated with acute respiratory infection. We sought to identify RSV variants associated with prolonged infection. Methods. Among healthy term infants we identified those with prolonged RSV infection and c ...
OXFORD UNIV PRESS INC2023Aerosol pH is an overlooked driver of airborne influenza and coronavirus inactivation
The current pandemic has added to the growing evidence that respiratory viruses can be transmitted by the airborne route. Non-pharmaceutical interventions, such as mask wearing or ventilation, aim to reduce the public health burden of respiratory diseases ...
2023The neuraminidase activity of influenza A virus determines the strain-specific sensitivity to neutralization by respiratory mucus
Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler
Respiratory mucus lining the airway epithelium constitutes an important first line of defense against infection with influenza A virus (IAV). Previous studies suggested that the inhibitory potential of mucus relies not only on the presence of decoy recepto ...
2023Polyanionic 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 ...
AMER CHEMICAL SOC2022High-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- ...
2022Expiratory Aerosol pH: The Overlooked Driver of Airborne Virus Inactivation
Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler
Respiratory viruses, including influenza virus and SARS-CoV-2, are transmitted by the airborne route. Air filtration and ventilation mechanically reduce the concentration of airborne viruses and are necessary tools for disease mitigation. However, they ign ...
