A single vaccination that provides protection for many years – so far, this has rarely been possible with vaccines against respiratory pathogens. While many vaccines offer long-term protection against severe illness, protection against rapidly mutating pathogens—such as influenza viruses or SARS-CoV-2—wanes quickly. Regular booster shots are therefore often necessary.
Dr. Henning Jacobsen and Casper Silvis from the Helmholtz Centre for Infection Research want to change that. As part of the ENDURIVAC project, they are developing a vaccine technology designed to provide long-lasting protection after just one dose. Their vector is the murine cytomegalovirus: It cannot make humans ill but is...

At first glance, mucus sounds more unpleasant than essential. In fact, it forms an important protective layer on our mucous membranes: It transports dirt, bacteria, and viruses out of the body and makes it difficult for pathogens to penetrate our cells in the first place.

Nanoinfection biologist Prof. Christian Sieben is studying this crucial moment in an infection in great detail. He heads the Nanoinfection Biology research group at the Helmholtz Centre for Infection Research and is a professor at the Technische Universität Braunschweig. Using state-of-the-art microscopy, he observes individual virus particles and investigates how they interact with our cells....

Schleim klingt zunächst eher unangenehm als lebenswichtig. Tatsächlich bildet er auf unseren Schleimhäuten eine wichtige Schutzschicht: Er transportiert Schmutz, Bakterien und Viren aus dem Körper und erschwert es Krankheitserregern, überhaupt in unsere Zellen einzudringen.

Nanoinfektionsbiologe Prof. Christian Sieben untersucht diesen entscheidenden Moment einer Infektion besonders genau. Er leitet die Forschungsgruppe Nanoinfektionsbiologie am Helmholtz-Zentrum für Infektionsforschung und ist Professor an der Technischen Universität Braunschweig. Mithilfe modernster Mikroskopie beobachtet er einzelne Viruspartikel und erforscht, wie sie mit unseren Zellen interagieren.

In dieser Folge von InFact spricht Host Julia Demann mit ihm darüber, wie Atemwegsviren unsere natürlichen Barrieren überwinden, warum gerade Influenzaviren ein...

At first glance, biology and computer science seem like opposites. In reality, however, computer science is something like a highly organized manager for modern biology: wherever enormous amounts of data are generated from research, progress is hardly possible without digital methods.

Bioinformatician Prof. Andreas Keller therefore relies on artificial intelligence. He heads the Clinical Bioinformatics research group at the Helmholtz Institute for Pharmaceutical Research Saarland, or HIPS for short – an institute founded in 2009 by the Helmholtz Centre for Infection Research and Saarland University.

In this episode of InFact, host Julia Demann talks to him about how AI can...
