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.

Until now, it has been technically nearly impossible to rotate highly sensitive samples in all directions under a microscope without making contact. Researchers at the KIT have developed a new laser-based technique that allows microscopic samples such as cells to be rotated contact-free in all three spatial directions. The laser creates tiny temperature differences in the liquid, which trigger gentle fluid flows that move the sample.

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.

A new technique based on labelled sugar molecules is providing previously unknown insights into the inner ear. A study by the University of Konstanz and Charité-Universitätsmedizin Berlin shows that the cupula in the inner ear of zebrafish completely regenerates within approximately two months. These findings open up a new avenue for research into sudden hearing loss and acute disorders of the sense of balance.

The cities of Heidelberg and Mainz want to work closely together in the future: Their aim is to further develop the Neckar-Rhine-Main region as an international innovation and biotech region. To this end, Heidelberg Mayor Würzner and Mainz Mayor Haase signed a MoU at Heidelberg City Hall on Friday, April 24, 2026. Those responsible for the central innovation and development structures of both cities also took part in the signing.

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

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.​

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.

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.
