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.

The Collaborative Research Centre (CRC) 1550 “Molecular Circuits of Heart Disease” at Heidelberg University is entering its second funding period. The German Research Foundation (DFG) has approved approximately EUR 17.4 million in funding for the next four years. The spokesperson is Johannes Backs, Professor of Experimental Cardiology at the Heidelberg Faculty of Medicine.

Whether people try to quit smoking depends heavily on public health policies in their respective countries – whether they are successful, however, depends primarily on their personal environment and behavior. This was the finding of researchers from the German Cancer Research Center (DKFZ) in an international study.

The ability of cancer cells to change their identity makes tumors such as glioblastoma particularly aggressive and resistant to treatment. Moritz Mall, of the German Cancer Research Center (DKFZ) and the Hector Institute for Translational Brain Research (HITBR), is investigating how this plasticity can be specifically restricted. His approach focuses on genetic “guardians” that suppress alternative cell programs.

Scientists from the German Cancer Research Center (DKFZ) and the HI-STEM* Stem Cell Institute have deciphered a key mechanism that contributes to treatment failure in acute myeloid leukemia (AML). They show that there are not just one, but four different subtypes of leukemia stem cells. This diversity could explain why one of the most important AML drugs does not work sufficiently in some patients or loses its effectiveness over time.

From May 15–16, 2026, the 3rd International Symposium “Frontiers in Skin Immunity” will bring leading experts in dermatology and immunology to Heidelberg. Organized by the SFB Transregio 156 “The Skin as Sensor and Initiator of Local and Systemic Immunity” and the Medical Faculty of Heidelberg University the meeting highlights advances in understanding skin immune responses and marks the conclusion of the consortium’s third funding period.

Her ground-breaking research studies on the regulation of gene activity have earned Dr Angelika Feldmann the Hella Bühler Prize for 2026, which is endowed with 100,000 euros.

Brain metastases are among the most serious complications of breast cancer. Researchers at Heidelberg University, DKFZ, and UKHD have concluded an investigation of the immune cells in the brain tissue surrounding these breast cancer brain metastases. Their findings: spatial distribution patterns of immune cells are associated with prolonged patient survival. These findings could help to guide use of immunotherapies for breast cancer patients.

Not only actual chronological age, but also individual aging at the molecular level is a key factor in the development of cancer. This was discovered by scientists at the DKFZ and the Saarland Cancer Registry. If the so-called “epigenetic clocks” indicate accelerated biological aging, the likelihood of a cancer diagnosis increases. This finding could help identify at-risk groups and make early detection screenings more targeted

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.

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.

How can artificial intelligence support medical imaging diagnostics in the future and significantly improve patient care? Researchers led by Lena Maier-Hein (German Cancer Research Center, DKFZ, and NCT Heidelberg) have developed an innovative concept to address this question. The Carl Zeiss-Stiftung is funding the MEDAL* project with a total of three million euros.

The Dr. Margarete Fischer-Bosch Institute for Clinical Pharmacology (IKP) at the Bosch Health Campus in Stuttgart is leading Europe’s first EU project to systematically integrate pharmacogenomics into molecular tumor boards (MTB). The goal of PGxMTB is to systematically incorporate patients’ genetic factors into treatment decisions, thereby making cancer therapies safer and more effective.

The introduction of mammography screening programs in Europe has significantly changed breast cancer diagnoses, accompanied by a decline in breast cancer mortality rates. This is shown by the most comprehensive analyses of population-based data on breast cancer in 21 European countries to date, led by the DKFZ. The most striking finding: after the introduction of screening, significantly more early-stage, less advanced tumors were detected.

Chemotherapy is often a central component of treatment for advanced colorectal cancer. However, not every therapy is equally effective for every patient. Researchers from the German Cancer Research Center (DKFZ), the HI-STEM* stem cell institute, and the biotech company Xilis in Utrecht, Netherlands, have now developed a new method for selecting the most effective drug before treatment begins.

In a published scientific study, researchers have succeeded in accurately diagnosing common types of brain tumors in children and adolescents based on tumor-derived genetic material in cerebrospinal fluid. Until now, these so-called liquid biopsies were not capable enough for such reliable diagnostics. The international research team has therefore optimized a sequencing technique and developed an AI-based computational method. In a later step,…

A severe side effect of radiation therapy can be debilitating fibrotic skin damage. Scientists at the German Cancer Research Center (DKFZ) have now identified a key factor in the development of this radiation damage. Modulating this factor could potentially prevent this severe adverse effect.

A key molecular mechanism drives the growth of liver cell cancer while simultaneously suppressing the body's immune response to the tumor. 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…

Scientists at the German Cancer Research Center (DKFZ), Heidelberg University Hospital (UKHD), and Mannheim University Medical Center (UMM) are presenting a method that enables artificial intelligence (AI) to learn how to transfer medical image data from animals to humans. This “xeno-learning” could help make surgical procedures safer and more precise in the future – without relying on human training data.

Researchers at the National Center for Tumor Diseases (NCT) Heidelberg and the German Cancer Research Center (DKFZ) have developed a digital tool that significantly accelerates and improves clinical decisions in molecular precision oncology. The Knowledge Connector enables the structured and standardized evaluation of very extensive molecular tumor profiles and makes them available for personalized therapy decisions faster than before.

Inflammation has to work fast against pathogens—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work shows that cells use two different strategies to precisely control inflammatory genes and thus precisely regulate the inflammatory response.

Can the weakened immune systems of older individuals be rejuvenated? Researchers from the DKFZ, HI-STEM*, and the Broad Institute have demonstrated that this is possible with an innovative approach. In a study, the team showed that mRNA technology can be used to transform the liver in mice into a temporary source of important immune regulatory factors that are naturally lost during aging.

Researchers at the Hopp Children's Cancer Center Heidelberg, the German Cancer Research Center, the Heidelberg Medical Faculty of Heidelberg University, and Heidelberg University Hospital have taken a decisive step toward more precise diagnosis of brain tumors. The latest version of the AI-based Heidelberg CNS Tumor Methylation Classifier can identify more than 180 tumor types —twice as many as the previous version.
