Estrogen does more than regulate reproduction — it helps brain cells handle stress. When levels decline after menopause, this ability is reduced, and these hormonal changes are believed to contribute to the increased risk of Alzheimer’s disease in women. MPI-IE researcher María José Pérez Jiménez has received the Klaus Tschira Boost Fund to investigate why — and whether these cellular responses can be restored.​

A recent study published in the European Respiratory Journal provides important new insights into the early identification and monitoring of chronic obstructive pulmonary disease (COPD). The focus is on airway wall thickness as an imaging marker for structural remodeling processes in the lungs.

A team of researchers from the Department of Integrative Evolutionary Biology at the Max Planck Institute for Biology Tübingen has discovered that vitamin B12 plays a key role in transmitting behavioural memories across generations. The study shows for the first time how a nutrient from the diet can, without altering the genome, influence behaviour over multiple generations.

Desmoplastic small- and round-cell tumor is rare, aggressive, and difficult to treat. Researchers at the National Center for Tumor Diseases (NCT) Heidelberg and the German Cancer Research Center (DKFZ) have comprehensively analyzed 30 tumors and identified potential personalized treatment options for nearly all patients. In some patients, new targeted approaches were able to halt the disease for a surprisingly long time.

Can Aztekin and his team have discovered how oxygen-sensing explains why amphibians regenerate limbs and mammals do not.

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 over a decade, a class of drugs called BET inhibitors has been tested in cancer trials with high expectations. The biology looked promising. Many cancers depend on oncogenes that (BET) proteins help activate, so blocking BET proteins should slow tumor growth. In the lab, it often did. In patients, results were mostly disappointing: limited responses, significant side effects, and no clear way to predict which tumors would respond at all.

Researchers in Freiburg have found a way to selectively replace defective immune cells in the blood vessels of the brain using an animal model. This is an important first step towards cell therapies for Alzheimer’s disease and other brain disorders. The findings were recently published in the journal Nature Immunology.

Proof-of-concept study of organoid technology - 26/03/2026

Can organoids improve the treatment of pancreatic cancer?

A clinical trial called UNITEPANC is exploring whether organoid-based approaches can improve the treatment of pancreatic cancer. BIOPRO Baden-Württemberg spoke with the study’s principal investigator and pancreatic cancer specialist, Prof. Dr. Thomas Seufferlein of University Hospital Ulm, to discuss the disease more broadly along with the specific aims of the trial. The interview was conducted by Walter Pytlik on behalf of BIOPRO.

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.

In ovarian cancer, immunotherapies using checkpoint inhibitors have so far been effective in only a small number of patients. Researchers at the HI-TRON Mainz* have now discovered that lipid metabolism processes in the tumor microenvironment play a decisive role in how well such therapies work. The findings open up new avenues for using immunotherapies in a more targeted manner, increasing their effectiveness, and overcoming resistance.

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.
