In May 2022, alarming headlines emerged: A mysterious and deadly disease was spreading in Central Africa. Was this the beginning of a new pandemic? Today, we know that it was Mpox (formerly known as monkeypox), a viral disease that has once again been declared a public health emergency. In this episode of the HZI podcast Infact, Dr Julia Port, head of the research group “Laboratory of Transmission Immunology” at the Helmholtz Centre for Infection Research (HZI), discusses virus transmission and the role of the immune system. Her research bridges immunology, viral ecology, and global health.

Today, the Citizen Science project CiFly will enter its second year. This year, 9th and 10th grade students from the Alexander-von-Humboldt-Gymnasium will again have the opportunity to get to know the Helmholtz Institute for One Health (HIOH), but also the chance to explore the biobank of the University Medical Center and the Greifswald Zoo from the perspective of a researcher.

Infectious keratitis blinds 1.5 million people worldwide every year. This severe eye disease is often caused by the hospital germ Pseudomonas aeruginosa, which the World Health Organization considers one of the most dangerous bacteria of its kind. Now, scientists at Saarland University and the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) have found a way to combat this resilient pathogen. Their study has been published in Advanced Science. The HIPS is a site of the Helmholtz Centre for Infection Research (HZI) in collaboration with Saarland University.

The CRISPR-Cas gene scissors offer a wide range of potential applications, from the treatment of genetic diseases to antiviral therapies and diagnostics. However, to safely harness their powers, scientists are searching for mechanisms that can regulate or inhibit the systems’ activity. Enter the anti-CRISPR protein AcrVIB1, a promising inhibitor whose exact function has remained a mystery—until now. A research team from the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg, in collaboration with the Helmholtz Centre for Infection Research (HZI) in Braunschweig, has uncovered the precise way AcrVIB1 works that expands the known means by which Acrs can shut down CRISPR. The results were published today in the journal Molecular Cell.

Construction of a modern new building for the Helmholtz Institute for One Health (HIOH) will begin this year on the University of Greifswald's Berthold-Beitz-Platz campus. Founded in 2021 as a site of the Helmholtz Centre for Infection Research (HZI), the institute works closely with its local founding partners, the University of Greifswald, the University Medical Centre Greifswald and the Friedrich-Loeffler-Institut. In line with the One Health approach, which considers human, animal and environmental health as an inseparable whole, the HIOH combines a variety of scientific disciplines. The common goal is to better understand the emergence of zoonotic diseases, antimicrobial resistance and the evolution of pathogens, and thus reduce the risk of new pandemics. In an increasingly interconnected world, in which pathogens that can be transmitted from animals to humans can travel across the globe in no time and develop resistance to drugs, the HIOH is making a decisive contribution to research into the origin and transmission of such infections – and is thus creating the basis for effective pandemic prevention measures.

The only natural host of the hepatitis C virus (HCV) is humans. Model organisms for laboratory studies, especially mice, cannot be infected which makes the search for a vaccine against HCV extremely difficult because the protective effect cannot be tested directly. In order to understand why the virus cannot infect mice and to enable the development of new animal models, researchers at TWINCORE in Hannover have generated an adapted virus variant that can infect mouse liver cells in vitro. They have now published their work in the Journal of Hepatology Reports. The TWINCORE is a joint institution of the Helmholtz Centre for Infection Research (HZI) in Braunschweig and Hannover Medical School (MHH).
