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.

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.

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…

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.

It has only recently become known that two parallel systems of blood formation exist in the body. Researchers at the DKFZ have developed a method to examine both systems separately in mice for the first time. Their surprising finding: the majority of immune cells do not originate from classic blood stem cells in the bone marrow, but from precursor cells that are independent of blood stem cells and are already present in the embryo.

Physician and cancer researcher Mirco Julian Friedrich from the German Cancer Research Center (DKFZ), the stem cell research institute HI-STEM*, and Heidelberg University Hospital (UKHD) has received two awards for two independent research projects: his novel approach to preventing liver metastases and his research on T cells, which he modifies to better protect them from attacks by natural killer cells.

In the PRECISION-ImmunoRad project, a multidisciplinary team of scientists from Heidelberg, USA, and Cyprus will unite their expertise to develop novel curative therapeutic strategies for currently hard-to-treat cancers. These strategies will integrate high-precision ion beam therapy with genetically engineered immune cells therapies (CAR-T cells), personalized cancer vaccines, and the targeted reprogramming of the tumor immune microenvironment.

Worldwide, almost one third of women of childbearing age suffer from bacterial vaginosis. Such a disorder of the vaginal flora can cause urogenital infections, abscesses on the ovaries or fallopian tubes or premature births. As part of a BW Sprint project, the DITF have laid the basis for the development of a panty liner that supports the health of the vaginal environment and can prevent bacterial vaginosis.

Federal government awards 3.5 million euros in funding to the collaborative research project FLU-PREP. Researchers are developing methods to identify the pandemic potential of new viruses at an early stage.

Human immunodeficiency viruses (HIV) are insidious. They can evade the immune defence and antiviral drugs by becoming "latent". In this state, they are largely invisible and unassailable. As long as these dormant viruses persist, there is no cure for HIV/AIDS. However, researchers at Ulm University Hospital have discovered a new way to reactivate latent HI viruses.

Researchers at Heidelberg Uni Hospital have decoded a previously unknown mechanism by which HIV-1 selects its integration targets in the human genome. A research team identified RNA:DNA hybrids as molecular signposts for the virus. These findings reveal a vulnerability in the life cycle of HIV and provide therapeutic approaches for specifically controlling HIV reservoirs in the body. This has been one of the obstacles to curative HIV therapies.

Researchers from the German Cancer Research Center (DKFZ) have collaborated with the SILVACX project group at Heidelberg University to develop a therapeutic vaccination concept that can mobilize the immune system to target cancer cells. The team showed that virus peptides coupled to silica nanoparticles can elicit effective T-cell responses against HPV-related tumors.

A team of scientists from the German Cancer Research Center (DKFZ) and the Netherlands Cancer Institute has discovered a previously unknown vulnerability in cancer cells: When cell division is blocked with chemotherapeutic agents such as Taxol, cancer cells produce small immunogenic peptides that could open up new avenues for immune-based cancer therapies.
