How Long COVID develops is still largely unknown. New molecular connections are revealed in a recent study led by the Centre for Individualised Infection Medicine (CiiM). Using their approach of examining different molecular levels within individual cells, the researchers identified a specific condition in immune cells that was directly associated with elevated inflammation markers, fatigue, and respiratory problems in patients with Long COVID. The study was published in the journal Nature Immunology. The CiiM is a joint institution of the Helmholtz Centre for Infection Research (HZI) and Hannover Medical School (MHH).

The Helmholtz Association is kicking off 2026 with new research initiatives on strategic future topics to bring technological breakthroughs into practical application more quickly. The Helmholtz initiatives “Biomedical Engineering Initiative,” “Water Safety and Security Initiative,” and “Quantum Use Challenge” are generating innovative solutions – from needle-free blood glucose measurement via wearables to quantum sensors for more powerful batteries and innovative concepts for water management in large cities. The initiatives are being developed in close cooperation with partners from politics, business, and society and address key technologies and strategic research areas of the German government’s High-Tech Agenda. Four projects of the Helmholtz Centre for Infection Research (HZI) and its sites in Greifswald, Saarbrücken and Würzburg are part of the new research campaigns.

For decades, tuberculosis (TB) has been one of the deadliest infectious diseases worldwide. Resistant strains of Mycobacterium tuberculosis are particularly problematic, as many established drugs are becoming increasingly ineffective against them. However, a research team from the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) and Saarland University has now discovered a new family of natural substances that exhibit excellent activity against the TB pathogen. They have also investigated these substances so comprehensively that targeted further development is possible for the first time. The researchers have now published their findings in the journal Angewandte Chemie International Edition.

Two collaborative projects involving the Helmholtz Centre for Infection Research (HZI) are being funded with 100,000 euros each from the joint program "zukunft.niedersachsen" of the state of Lower Saxony and the Volkswagen Foundation. Both projects result from the collaboration between HZI and the MRC–University of Glasgow Centre for Virus Research (CVR), established in 2024 as part of a cooperation between the Helmholtz Association and the British Medical Research Council (MRC). The funded MARITH project will grow organoids from throat tonsil tissue to study the development of immunological memory in humans, while the ViReST project analyzes the sites of viral replication in respiratory infections and their impact on virus transmission.

The global skin care company Beiersdorf and the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) have entered into a long-term, exclusive partnership. In this collaboration they aim to investigate the role of the skin microbiome in maintaining healthy skin. The goal is to identify natural products produced by microorganisms on the skin that have a positive effect on skin balance. The project is based on extensive data sets on microorganisms that inhabit human skin.

The CRISPR “gene scissors” have become an important basis for genome-editing technologies in many fields, ranging from biology and medicine to agriculture and industry. A team from the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg has now demonstrated that these CRISPR-Cas systems are even more versatile than previously thought. In cooperation with the Helmholtz Centre for Infection Research (HZI) in Braunschweig and Utah State University (USU) in Logan (USA), the scientists have discovered a novel CRISPR defense mechanism: Unlike known nucleases, Cas12a3 specifically destroys transfer ribonucleic acids (tRNA) that are vital for protein production to shut down infected cells. The team published its findings today in the journal Nature.
