Neural anticipation of virtual infection triggers an immune response

Once contact with a pathogen has occurred, it might be too late for the immune system to react. Here, we asked whether anticipatory neural responses might sense potential infections and signal to the immune system, priming it for a response. We show that p ...

Evolving Infectious Disease Dynamics Shape School-based Intervention Effectiveness

Sebastian Maerkl, Grégoire Michielin

School-based interventions during epidemics are often controversial, as experienced during the COVID-19 pandemic, where reducing transmission had to be weighed against the adverse effects on young children. However, it remains unclear how the broader epide ...

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

Aleksandar Antanasijevic, Philippe André Guy Colin

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 ...

Basic Mechanisms of Immunometabolites in Shaping the Immune Response

Alexander Hooftman

Background Innate immune cells play a crucial role in responding to microbial infections, but their improper activation can also drive inflammatory disease. For this reason, their activation state is governed by a multitude of factors, including the metabo ...

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

Didier Trono, Priscilla Turelli

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 ...

Emerging dimensions of cellular cGAS-STING signaling

Andrea Ablasser, Baptiste Claude André Guey

The recognition of DNA through the cGAS-STING pathway plays a critical role in antiviral immunity, but can also drive maladaptive immune responses underlying several pathological conditions. Despite its importance, understanding the organization of cGAS-ST ...
