In people with severely compromised immune systems, the JC polyomavirus can trigger a currently untreatable, usually fatal brain disease. Now, an international research team looking at the viral capsid has identified binding sites for neutralizing antibodies; these sites could be used to halt infection with JC polyomaviruses.

A novel vaccination strategy against certain malignant brain tumors could fundamentally improve treatment for patients. Researchers from the German Cancer Research Center, Mannheim University Medical Center, Heidelberg University Hospital, and numerous partner institutions* have published encouraging long-term results from a clinical trial involving a vaccine that activates the immune system against a common genetic mutation in these tumors.

Researchers at the German Cancer Research Center (DKFZ) have identified a previously unknown key mechanism by which cancer cells suppress the immune system and thus evade the effects of immunotherapies. At the same time, the new study in mouse models and human tumor samples points to a promising way to prevent resistance to immunotherapy.

Primary CNS lymphomas in immunocompromised patients are among the rarest and at the same time most aggressive cancers – yet evidence-based recommendations for their diagnosis and treatment have been lacking. An international research team led by the Heidelberg Faculty of Medicine at Heidelberg University and the German Cancer Research Center has now identified characteristic imaging features of these tumors and developed a prognostic model.

An environmental bacterium could protect against the effects of stress right through to the next generation. Evidence of this emerged in a study using a mouse model carried out by researchers from Ulm and Frankfurt, the results of which were published in the journal `Molecular Psychiatry´. According to the study, the offspring of treated mothers were better protected against the effects of stress in adulthood than control animals.

Cancer researcher Dr Alexandra Niedermayer from the Ulm Children’s and Adolescents’ Clinic has been awarded the Franziska Kolb Prize, worth 8,000 euros, by the Ulm University Foundation. The 32-year-old researches aggressive forms of blood cancer and, using modern techniques, has identified an effective, personalised treatment approach.

On Thursday, 25 June 2026, several Freiburg cancer researchers were honoured at the presentation of the CRIION Joachim Frank Prize 2026. Among them was Prof. Dr Robert Zeiser, who received the Prize for Biomedical Research. Prof. Dr Jürgen Finke, PD Dr Florian Scherer and PD Dr Elisabeth Schorb of the University Medical Center Freiburg, together with Prof. Dr Gerald Illerhaus of Stuttgart Hospital, were awarded the Prize for Clinical Medicine.

In order to further strengthen Heidelberg University as an internationally recognized location of infection research, Prof. Dr Mathias Lichterfeld has been selected for an Alexander von Humboldt Professorship endowed with 7.8 million euros. Leading international academics are granted this most valuable of German research awards to enable them to conduct long-term, cutting-edge research at German universities.

The German Research Foundation (DFG) funds continuation of Research Training Group (RTG) 2727 “Checkpoints of Innate Immunity in Cancer and Tissue Damage”, with around €5,8 million.

Which cellular processes ensure that immune responses are controlled precisely? A new study by the Institute of Cell Biology and Immunology Thurgau (BITG) and the University of Konstanz decodes a decisive signalling pathway.

Different types of bone marrow stem cells give rise to blood and immune cells. A team led by Simon Haas now reports in ​“Nature Cell Biology” how that diversity develops. The findings could help improve stem cell therapies, including treatments for blood cancers.

Cancer prevention with a single jab - 20/05/2026

Therapeutic vaccine against HPV-induced tumours

Persistent infections with human papillomaviruses (HPV) are the primary cause of cervical cancer. Researchers from Heidelberg have developed a promising therapeutic vaccine consisting of immunogenic virus peptides linked to silica nanoparticles, which is currently being investigated in preclinical studies. The vaccine activates specific cytotoxic T cells and is usable regardless of HLA type.

Research jointly led by scientists at the Heidelberg site of the German Center for Lung Research and investigators in Boston at Massachusetts General Hospital and Harvard Medical School identifies a new immunotherapy-based approach for lung fibrosis: reactivating natural killer cell (NK cells) to eliminate senescent fibroblasts, reverse scarring and restore the lung’s ability to heal.

Medical Center – University of Freiburg demonstrates a fundamental therapeutic approach for hereditary immune system defects in a mouse model. The safety profile of genome editing varies significantly depending on the method and cell type.

Chronic infections cause long-term changes in key immune cells. T helper cells suppress their immune function to ensure their survival. New targets for vaccines and cancer immunotherapies.

Photoimmunotherapy - 09/04/2026

Switching off tumours with light: how photons can be used to target prostate cancer

Prostate cancer is the most common cancer among men in Germany. Relapses and the harsh side effects of traditional treatments remain a major challenge, even with advanced surgical techniques. At the University of Freiburg, Dr. Wolf is pioneering the development of photoimmunotherapy. Photoimmunotherapy combines light, antibodies and a specialised dye to precisely target tumour cells - simultaneously 'waking up' the immune system.

For the first time, researchers have succeeded in mapping the organization of immune cells in human lymph nodes. The study was led by scientists from Heinrich Heine University Düsseldorf, Düsseldorf University Hospital, the DKFZ, the European Molecular Biology Laboratory (EMBL), and the Max Delbrück Center (MDC) in Berlin. They were able to demonstrate why the architecture of healthy lymph nodes is altered in malignant lymphomas.

Traumatic brain injuries often lead to complications with long-lasting consequences on memory, concentration and movement control. Detrimental secondary inflammatory reactions at the injured tissue sites are often responsible for this. Researchers from Ulm have now shown that a transcription factor plays a key role in reactions to TBI. When this gene regulator is activated, an elevated neuroimmune response promotes inflammation.

Why does heart function often continue to deteriorate after a heart attack, even though blood flow has been restored? A research team from the DZHK sites Heidelberg and North has now identified an important mechanism: an inflammatory switch in cardiomyocytes can impair cellular energy production and thereby drive the development of heart failure. The results were published in Nature Communications.

Ageing is a highly individual process. An international consortium coordinated by researchers in Konstanz has developed a method that uses biomarkers to determine a person's biological age – a valuable tool for research on ageing and the development of new approaches in preventive medicine.

New findings indicate that a shingles vaccination could not only reduce the risk of cognitive impairment and dementia, but also reduce disease progression among those living with dementia.

Even before a tumour in the pancreas becomes discernible, an activated cancer gene actively remodels its future environment and creates an inflammatory and immune-defensive microenvironment in which the carcinoma can grow. The scientists' study opens up new possibilities for developing personalised intervention strategies - before a difficult-to-treat tumour even develops.

This has now been published in the journal Nature by a team led by researchers from the DKFZ, the UKT, and the Sanford Burnham Prebys Medical Discovery Institute. However, the results also show that this very mechanism could help identify patients who respond particularly well to immunotherapy in the…
