Induction of a strong and long-lasting neutralizing immune response by dPreS1-TLR2 agonist nanovaccine against hepatitis B virus

Myriam Isabelle Lamrayah

Hepatitis B virus remains a major medical burden with more than 250 million chronically infected patients worldwide and 900,000 deaths each year, due to the disease progression towards severe complications (cirrhosis, hepatocellular carcinoma). Despite the ...

Glycan heterogeneity as a cause of the persistent fraction in HIV-1 neutralization

Philippe Colin, Aleksandar Antanasijevic

Neutralizing antibodies (NAbs) to multiple epitopes on the HIV-1-envelope glycoprotein (Env) have been isolated from infected persons. The potency of NAbs is measured more often than the size of the persistent fraction of infectivity at maximum neutralizat ...

Microfluidic characterisation reveals broad range of SARS-CoV-2 antibody affinity in human plasma

Didier Trono, Priscilla Turelli, Marc Emmenegger

The clinical outcome of SARS-CoV-2 infections, which can range from asymptomatic to lethal, is crucially shaped by the concentration of antiviral antibodies and by their affinity to their targets. However, the affinity of polyclonal antibody responses in p ...

Humoral Responses Against Variants of Concern by COVID-19 mRNA Vaccines in Immunocompromised Patients

Didier Trono, Céline Pellaton, Madeleine Suffiotti

IMPORTANCE There are limited comparative data on the durability of neutralizing antibody (nAb) responses elicited by messenger RNA (mRNA) vaccines against the SARS-CoV-2 variants of concern (VOCs) in immunocompromised patients and healthy controls. ...

Preliminary evidence that daily light exposure enhances the antibody response to influenza vaccination in patients with dementia

Jean-Louis Scartezzini

Enhancing lighting conditions in institutions for individuals with dementia improves their sleep, circadian rhythms and well-being. Here, we report first findings that exposure to brighter light during daytime may support the immune response to the annual ...

A Nanoscaffolded Spike-RBD Vaccine Provides Protection against SARS-CoV-2 with Minimal Anti-Scaffold Response

David Hacker, Bruno Emanuel Ferreira De Sousa Correia, Florence Pojer, Kelvin Ka Ching Lau

The response of the adaptive immune system is augmented by multimeric presentation of a specific antigen, resembling viral particles. Several vaccines have been designed based on natural or designed protein scaffolds, which exhibited a potent adaptive immu ...
