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.

Why do metastases often only appear after the original tumor has been surgically removed? Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Mannheim Medical Faculty of Heidelberg University have now published an explanation for this phenomenon. They were able to identify a messenger substance of the cancer cells that locally promotes the growth of the primary tumor.

Whole blood model enables development of early warning system for sepsis

Sepsis is a life-threatening disease that can be treated all the more successfully the faster therapy is initiated. It is not just the infection itself that is so dangerous, but a dysregulated response of the immune system. Physicians at Ulm University Hospital have now developed an animal-free test system that can be used to research the disease and develop innovative diagnostic tools to quickly assess a patient's sepsis risk and optimise…

Reduced immunosuppression possible in transplantations - 05/06/2023

Modified immune cells produce donor-specific tolerance

Traditionally, transplant recipients have had to take immunosuppressive medication for life to prevent organ rejection. However, there are considerable side effects involved. Using modified immune cells (MICs), TolerogenixX GmbH from Heidelberg has now managed to generate donor-specific tolerance in recipients of living kidney transplants without suppressing the overall immune system.

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,…

Scientists from the German Cancer Research Center (DKFZ) and Heidelberg University Hospital (UKHD) have shown that the combination of therapeutic immune cells, known as CAR T cells, and a bispecific antibody could improve the treatment of leukaemia. In the culture dish and in mice, they tested CAR-T cells directed against the B-cell marker CD19 in combination with bispecific antibodies that bind to the B-cell-specific protein CD20.

With mice, researchers showed that experimentally induced lack of blood flow in the brain epigenetically reprograms astrocytes into brain stem cells, which in turn can give rise to nerve progenitor cells. This discovery shows that astrocytes could potentially be used in regenerative medicine to replace damaged nerve cells.

Age-related macular degeneration (AMD) is the commonest cause of blindness in developed countries affecting seven million in total in Germany, from which 500,000 people are suffering from late stage disease, around half of whom are registered as visually impaired. There are two forms of AMD, ‘wet’ and ‘dry’. There are currently no treatments available for the dry form of the disease (geographic atrophy).

Researchers at the Faculty of Medicine at the University of Freiburg have gained significant new insights into metabolic processes in the kidney. The scientists from the Institute of Genetic Epidemiology at the Medical Center - University of Freiburg measured tiny molecules, so-called metabolites, which occur in blood and urine and reflect our metabolism, in samples from more than 5,000 study participants.

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) is funding a new Emmy Noether junior research group at the DKFZ for six years with a total of around 2 million euros. The scientists and doctors, who are part of the Clinical Cooperation Unit for Pediatric Leukemia at the KiTZ, are using a new procedure to investigate how cancer cells manipulate the formation of proteins to become resistant to cancer drugs.

Biosensor for whole blood and exhaled breath analysis - 02/02/2022

Antibiotic detection from whole blood or exhaled breath possible

Incorrectly dosed antibiotics are not only dangerous for patients, but also often the cause of resistant strains of bacteria. Researchers at the University of Freiburg have developed a biosensor to determine the effective amount and thus enable personalised therapy. The biosensor works by rapidly determining small amounts of the substances directly from whole blood or exhaled breath.

Blood-based biomarkers allow the early prediction of Alzheimer's risks

Most dementia diseases develop insidiously and are only detected at an advanced stage. Researchers at the University of Heidelberg and the German Cancer Research Center (DKFZ) have now identified the glial fibre acidic protein (GFAP) in the blood as a promising biomarker that can be used to determine an increased risk of developing Alzheimer's disease up to 17 years before diagnosis.

Immunotherapies have greatly improved the treatment of metastatic melanoma, but they can cause serious side effects. A study led by researchers from Heidelberg University's Medical Faculty, the Heidelberg University Hospital, and the NCT in Heidelberg now shows that autoantibodies detected in the blood before the start of therapy could help to better assess the individual risk of side effects in patients.

Researchers have developed a promising cellular immunotherapy for the treatment of glioblastomas: They equipped T cells with a receptor that recognizes a protein of the brain tumors that is responsible for the dangerous stem cell properties. The therapeutic T cells directed against this target structure were able to specifically destroy human brain tumors in laboratory experiments and in mice.

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.

Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-sized microrobots individually and at high resolution in a living organism. This is an important step towards precise control of the robots and their clinical translation.

medicalvalues – best possible diagnostics thanks to AI

The Karlsruhe-based start-up medicalvalues GmbH wants to use its platform to bring together different clinical data sets and thus enable comprehensive medical diagnostics. Artificial intelligence featuring innovative diagnostic algorithms is used to evaluate the data and generate new insights for laboratories and hospitals.

Researchers have developed a new method that enables a more precise analysis of individual tumor cells circulating in the blood. This allows not only the previously possible genomic investigation of such tumor cells, but also the focused analysis of single-cell signaling pathways at the functional protein level. The combined analysis of the mutated genome and signaling proteins opens up new avenues for more targeted treatment methods.

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions have hardly been studied to date. Researchers from the German Cancer Research Center, the Mannheim Medical Faculty and Columbia University have now published that hepatic stellate cells control liver metabolism as well as liver regeneration and size. The results of the study could contribute to new therapeutic approaches for liver diseases.

How does sugar affect relaxation exercises? A new study carried out by researchers from the University of Konstanz provides revealing insights into the connection between blood glucose and the autonomic nervous system: The intake of sugar counteracts relaxation.

Cancer therapy and cancer diagnostics

Thanks to improved diagnostics and therapy, today’s cancer patients can live considerably longer than patients several years ago. Nevertheless, some cancers, especially the strongly metastatic ones, are difficult to treat. Therapies targeting immune cells or cancer stem cells could potentially improve the current situation.

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.

New edition - 24/05/2019

Tumour metastasis

Cancer is usually not curable when metastases have formed in the body. Metastases are often resistant to drugs that have successfully eliminated the primary tumour. The basic features of the complex process of metastasis are now known, but many details still remain elusive. Intensive research activities are focusing on new therapeutic concepts aimed at developing effective anti-metastatic therapies.

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).

Inovedis GmbH’s innovative implant - 28/03/2023

Next-generation minimally invasive shoulder surgery

The treatment of shoulder injuries such as rotator cuff tears is one of the most common orthopaedic interventions. It is therefore quite surprising that the surgical procedure has not changed much for decades - although it is relatively complicated. The start-up Inovedis has now developed a completely new surgical technique based on an implant that can be performed simply, safely, quickly and cost-effectively with minimal stress for patients.
