Detecting drug resistance of tumour cells - 25/05/2023

AI-assisted diagnostics declares war on lung cancer

Lung cancer is one of the most common cancers and has a particularly high mortality rate. A significant challenge in treating this disease lies in the resistance of lung tumours to conventional drug therapies, rendering chemotherapy ineffective. There is hope on the horizon as a team of experts from Baden-Württemberg has joined forces to develop an innovative AI-supported test procedure that paves the way for individualised therapy approaches.

Inflammatory fatty liver disease (NASH, non alcoholic steatohepatitis ) and the resulting liver cancer are driven by autoaggressive T cells. Scientists from the German Cancer Research Center (DKFZ) now show what ist behind this destructive behavior. In both mice and humans with NASH, they found increased numbers of activated B cells in the gastrointestinal tract.

Chronic myeloid leukemia (CML) is a type of blood cancer that arises from malignant changes in blood-forming cells of the bone marrow. It mainly occurs in older individuals and represents about 20 percent of all adult leukemia cases. A research team from the Institute of Molecular Medicine and Cell Research at the University of Freiburg has now demonstrated for the first time that mast cells play a crucial role in the development of CML.

The recently established ITCC-P4 gGmbH provides academic institutions and pharmaceutical companies with a comprehensive repertoire of modern laboratory models of pediatric tumors.

Triple-negative breast cancer (TNBC) is the most aggressive and deadly form of breast cancer with limited treatment options. Tumor growth and relapse of TNBC are driven by breast cancer stem cells, and improved therapies that can eliminate those hardy cells are urgently needed. Researchers from the University of Frieburg discovered that coordinated differentiation and changes in the metabolism of breast cancer stem cells make them invisible for…

Development of anti-tumour agents - 20/03/2023

Targeting the protective shield of cancers

Cancer cells have different mechanisms to help them escape destruction by the immune system. Solid tumours, for example, are often surrounded by a protective layer of lactate, which has a strong immunosuppressive effect. WMT AG from Heidelberg is developing small drug molecules that reduce lactate production and thus make cancer cells vulnerable to immune system attacks.

Researchers have created a tool that maps how breast cancer grows in previously unseen detail, and highlights how the cells around the tumour may be the key to controlling the spread of disease. The new technology can trace which populations of breast cancer cells are responsible for the spread of the disease, and for the first time highlights how the location of cancer cells could be as important as mutations in tumor growth The new study is…

Viral cancer therapy - 26/10/2022

Therapeutic viruses against tumours and metastases

Viruses can overcome cell barriers and transfer information to their host cells. They know how to make their host cell’s infrastructure work for them. This makes them excellent biotechnological tools, which a research group from the Fraunhofer IGB in Stuttgart is using to its advantage. The team is developing a therapeutic virus that not only recognises and fights tumours, but also has the potential to reach metastases.

Does COVID-19 vaccination increase the risk of cancer patients undergoing therapy with immune checkpoint inhibitors to suffer a dangerous immune complication known as a "cytokine release syndrome"? A team of Heidelberg physicians and scientists has now shown in a clinical study: Increased serum levels of the characteristic cytokines occur frequently in cancer patients, but clinically relevant cases of the dreaded syndrome were not…

ValidaTe enables characterization of efficacy and safety of T-cell drug candidates in days rather than months. The breakthrough speed and unprecedented density of data processed can give partner companies a competitive advantage. New high-throughput microarray technology for label-free characterization of drug candidate interactions can significantly accelerate development in immune-oncology.

Through the Endeavour Awards, the Mark Foundation supports research projects that bring together scientists from different disciplines to advance the prevention, diagnosis and treatment of cancer. One of the only four Endeavour Awards presented this year goes to a project coordinated by scientists from the German Cancer Research Center (DKFZ).

Researchers at Heidelberg University Hospital (UKHD), the German Cancer Research Center (DKFZ) and at the National Center for Tumor Diseases (NCT) Heidelberg have demonstrated for the first time that there is a link between the development of colorectal cancer in individuals with Lynch syndrome and the composition of immune cells in the colorectal mucosa.

The development of immunotherapies against blood cancer could be more successful if T cells are activated moderately rather than excessively. Scientists from the German Cancer Research Center have now been able to show this in mice: If the researchers blocked a cytokine that slows down the immune system, the T cells became exhausted and failed in the fight against leukemia.

At Tübingen University Hospital, a preclinical study led by Dr. Clemens Hinterleitner and Prof. Dr. Lars Zender, Medical Director of Medical Oncology and Pneumology, led to extremely promising results. The research group was able to develop a new methodology that makes it possible to better predict the likelihood of success of immunotherapies for lung cancer.

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have developed antibodies that have two antigen-binding sites and can couple cancer cells with effector cells of the immune system. In laboratory tests, these bridging antibodies, together with an enhancer antibody, were able to specifically mobilize the body's own immune defenses and destroy breast cancer cells.

Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.

Signal mechanisms in inflammatory processes - 18/05/2021

Newly discovered substances activate the inflammasome in macrophages

Low-grade chronic inflammation caused by components of the innate immune system may increase the risk of developing a variety of diseases in the long term. In their search for the signalling mechanisms underlying these inflammatory processes, Prof. Dr. Olaf Groß' research group at the Freiburg University Medical Centre discovered new active substances with immunostimulatory properties that may open up additional possibilities in cancer…

The working group around Dr. Philipp Rathert at the Institute for Biochemistry and Technical Biochemistry investigates the regulation of epigenetic networks of certain cancers and ways of treating them. The working group published its new findings in April.

Immunotherapy using checkpoint inhibitors is effective in around a quarter of patients with liver cancer. However, to date, physicians have been unable to predict which patients would benefit from this type of treatment and which would not. Researchers from the German Cancer Research Center have now discovered that liver cancer caused by chronic inflammatory fatty liver disease does not respond to this treatment. On the contrary: in an…
