It has long been suspected that endothelial cells play a key role in determining how the body’s immune system responds to tumors. Researchers at the DKFZ and the Medical Faculty Mannheim of Heidelberg University have now identified, in mouse studies, a specialized population of blood vessel lining endothelial cells that enable an effective immune defense against cancer metastases in the liver.

Researchers at the NCT Heidelberg and the German Cancer Research Center (DKFZ) have, for the first time, systematically determined how specific mutations promote acute myeloid leukemias. The results show why IDH1- and IDH2-mutated leukemias develop differently despite similar molecular mechanisms—and open up new approaches for diagnostics and targeted therapies.

Being overweight and obesity may contribute to significantly more cancer cases than previously thought. This is the conclusion reached by researchers at the German Cancer Research Center (DKFZ). Their analysis shows that when more accurate measures of body fat and methodological biases are considered, more than 10 percent of all cancer cases can be attributed to increased body weight - nearly twice as many as previous estimates suggested.

The Friends of the German Cancer Research Center (DKFZ) support the DKFZ and aim to help strengthen its position in the international arena.

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.

Through its “Proof of Concept” (PoC) grants, the European Research Council (ERC) supports scientists in further developing the economic potential of their research findings. In 2026, two scientists from the German Cancer Research Center (DKFZ) were once again selected to receive this prestigious funding: Moritz Mall and Chong Sun.

A team led by researchers from the German Cancer Research Center and the HI-STEM* Stem Cell Institute has discovered a new approach to treating advanced colorectal cancer. The study identifies a key marker of particularly aggressive and treatment-resistant colorectal cancer cells. At the same time, the researchers demonstrate using models that already approved drugs targeting this marker can specifically attack the metastasis-initiating cells.

Four doctoral candidates from Heidelberg University have the opportunity to exchange ideas with outstanding scientists. They are set to take part in the 75th Lindau Nobel Laureate Meeting, which is being held in Lindau from 28 June to 3 July 2026. Jana Braunger, Tim Schubert, Laura Rueda Gensini and Nathan Trausch are among around 600 young researchers who have been selected for their outstanding academic achievements.

The European Research Council (ERC) supports visionary projects in basic research through its “Advanced Grants.” This year, the Council awarded a grant to cancer researcher and physician Dieter Saur from the DKTK Munich* site, and Aurelio Teleman, a metabolism expert at the German Cancer Research Center (DKFZ).

Experts in Heidelberg have developed an AI system that can classify brain tumors with unprecedented accuracy using standard microscopic tissue sections. Using digitized standard stains, the system identifies more than 100 molecular subtypes of central nervous system tumors, delivers results within minutes, and could accelerate the diagnosis of brain tumors worldwide.

In response to stress or damage, cells undergo senescence and stop dividing. However, if senescent cells accumulate in tissues over the long term, chronic inflammation occurs and the risk of cancer increases. Researchers at the German Cancer Research Center (DKFZ) have now discovered a previously unknown mechanism by which senescent cells protect themselves from oxidative stress and a specific form of cell death known as ferroptosis.

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.

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.

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
