The long-standing President of the Thünen Institute, Prof. Dr Folkhard Isermeyer, passed away on 14 January 2025 at the age of 67. With his passing, the Thünen Institute has not only lost its ‘architect’, an excellent scientist and clever strategist, but also a personality who led with trust, an open ear and human warmth.

A team of scientists at the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg and the University of Regensburg has unveiled insights into how HIV-1, the virus responsible for AIDS, skillfully hijacks cellular machinery for its own survival. By dissecting the molecular interplay between the virus and its host, the researchers identified novel strategies that HIV-1 employs to ensure its replication while suppressing the host’s cellular defenses. The study was published in the journal Nature Structural and Molecular Biology.

Antibiotics are a double-edged sword – they should be as toxic as possible to pathogenic bacteria while being harmless to the cells of the human body. An international research team led by the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) has now developed drug candidates that achieve precisely that. The new molecules target a metabolic pathway that only occurs in bacterial cells, thus sparing human cells. The team published its results in the journal Angewandte Chemie International Edition.

Researchers at the Helmholtz Institute for RNA-based Infection Research (HIRI) and the Julius-Maximilians-Universität (JMU) in Würzburg have identified a protein and a group of small ribonucleic acids (sRNAs) in Bacteroides thetaiotaomicron, which regulate sugar metabolism. These discoveries shed light on how this gut microbe adapts to varying nutritional conditions. The findings deepen our understanding of this bacterium's role in the human gut and may pave the way for new therapeutic strategies to promote health through the microbiota. The study was published in the journal Nature Communications.

Researchers at the Helmholtz Centre for Infection Research (HZI) have developed a promising new vaccine technology. Their studies to date show that just one dose of vaccine leads to effective and long-lasting immune protection. The basis of this so-called MCMV vaccine vector technology is the mouse cytomegalovirus (MCMV). It acts as a carrier virus that introduces selected antigens of a pathogen to be vaccinated against into the body. In the follow-up project VIVA-VEK-2, which was launched at the HZI at the beginning of January, a proof-of-concept vaccine candidate against respiratory syncytial virus (RSV) is now to be produced and tested for efficacy and tolerability. The researchers believe that with the new vaccine technology, one vaccine dose could possibly even provide lifelong protection. The project is funded by the GO-Bio initial program of the Federal Ministry of Education and Research (BMBF) over two years with a funding volume of one million euros.

The interdisciplinary project DEFENDER is developing innovative approaches to combat (re-)emerging viruses. The project, coordinated by the Leibniz Institute of Virology (LIV), is being funded with around eight 9.6 million euros as part of Horizon Europe. Almost 700,000 euros of these will go to Prof. Mark Brönstrup, a researcher at the Helmholtz Centre for Infection Research (HZI) and the German Center for Infection Research (DZIF).
