Cancer cells often grow in environments that are low in nutrients, and they cope with this challenge by switching their metabolism to using proteins as alternative "food". Building on genetic screens, an international team of scientists could identify the protein LYSET as part of a pathway that allows cancer cells to make this switch. Their findings are now published in the journal Science.

University of Tübingen team discovers how malformations of the blood vessels can occur in mice – yielding information with possible ramifications for retinal disease.

In mice, inflammation in early to mid-life leads to a permanent decline in functional blood stem cells, according to a recent publication by scientists from the German Cancer Research Center (DKFZ) and the Stem Cell Institute HI-STEM*. The ability of the blood stem cells to regenerate was suppressed for at least one year after challenge with inflammation.

RHEACELL GmbH - 28/07/2022

Innovative stem cell therapy for chronic wounds

Non-healing, chronically inflamed wounds can be very painful and carry the risk of serious infections. The Heidelberg company RHEACELL has developed a unique drug based on ABCB5-positive mesenchymal stem cells that helps reprogramme the relevant immune cells and promote healing.

Organ-on-chip for the analysis of drug effects - 20/07/2022

New 3D cell platform allows continuous metabolic monitoring

Organ-on-chips systems are systems containing miniature tissues grown inside mircrofluidic chips. By integrating microsensors, researchers at the IMTEK Freiburg, together with the RWTH Aachen University Hospital, created a novel variant that allows the measurement of metabolic activity directly on site and in real time. This enables the rapid and detailed analysis of drug effects outside an organism.

AaviGen GmbH: Hope for heart failure - 14/07/2022

Gene therapy for weakened hearts

Treating a weak heart – for example after a heart attack – at the GP’s surgery with a single intravenous injection, without causing serious side effects: what sounds almost too good to be true is actually already under development. The Heidelberg-based biotech company AaviGen is working on a platform technology based on adeno-associated viruses that can help introduce therapeutic genes in a highly specific way into diseased heart muscle cells.

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…

Assay to support the diagnosis of autoimmune diseases - 22/06/2022

Tracking down pathogenic immune complexes

Soluble complexes of antibodies and their target structures circulating in the blood can trigger serious systemic inflammations. Dr. Philipp Kolb and Haizhang Chen from the Institute of Virology at the Freiburg University Medical Centre have developed a sensitive, cell-based test system for detecting these immune complexes. The system can be used to diagnose systemic autoimmune diseases, and also severe cases of COVID-19.

Alzheimer's, Parkinson's and other neurodegenerative diseases are associated with inflammatory processes in the brain. German researchers have succeeded in identifying a group of proteins in the liquor that could provide information about such inflammatory processes. As so-called biomarkers, the proteins could help to better understand disease processes in the future and to test the effect of potential drugs against brain inflammation.

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.

Metastatic breast cancer cells abuse macrophages, a type of immune cell, to promote the settlement of cancer metastases in the lungs. The reprogrammed macrophages stimulate blood vessel cells to secrete a cocktail of metastasis-promoting proteins that are part of the so-called metastatic niche.

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.

COVIC-19 clinical trial - 07/04/2022

Convalescent plasma for COVID-19 therapy: clinical trial should bring clarity

Does it help to treat COVID-19 sufferers with antibodies from people who have recovered from the disease? It seems an obvious idea and has been tested thousands of times. However, there is not yet enough evidence to prove the clinical efficacy of treating COVID-19 patients with convalescent plasma. The transfusion physician Prof. Dr. Hubert Schrezenmeier from Ulm is planning to carry out a follow-up clinical trial to find the missing evidence.

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).

In order to develop approaches for the prevention and treatment of Alzheimer's dementia in clinical trials, it would be helpful to be able to identify people with a particularly high risk of developing the disease. But which biomarkers can indicate an increased likelihood of disease early on in symptom-free people who actually develop Alzheimer's later?

Elastin as artificial muscle material - 02/03/2022

Artificial muscle from proteins for diverse future applications

As far as diversity and complexity are concerned, proteins are nature's smallest marvels. Biotechnologists have already used natural proteins as a basis for the development, bespoke design and production of artificial systems. This is what the livMatS cluster of excellence at the University of Freiburg has been doing. Researchers in the cluster have successfully produced an artificial muscle from elastin that functions autonomously.

Macrophages interacting with cytomegaloviruses - 22/02/2022

Cytomegaloviruses subvert macrophage identity

Cytomegaloviruses are basically harmless. However, if they occur along with other pathogens, they can trigger serious diseases. They can manipulate our immune system and encourage resident defence cells to migrate. Researchers at the Centre for Chronic Immunodeficiency (CCI) at the Freiburg University Medical Centre have discovered which mechanisms underlie the behavioural changes in macrophages that make it easier for other pathogens to attack.

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.

Researchers use epigenetic factors to investigate the role of stress in the development of tumor diseases. Experts believe that stress plays a major role in the development of tumors. One occupational group, for example, that experiences extreme stress over a short period of time is astronauts.

Dr. Stefan Schiller and Dr. Matthias Huber from the University of Freiburg’s livMatS Cluster of Excellence have succeeded in developing a muscle solely on the basis of natural proteins. The autonomous contractions of the material, which the researchers presented in the journal Advanced Intelligent Systems, can be controlled with the help of pH and temperature changes.

microRNA as a prognostic biomarker - 13/01/2022

Heart attack diagnosis: fast and unambiguous thanks to artificial intelligence

People that arrive in emergency rooms with chest pain require swift action in order to rule out a heart attack or to initiate vital life-saving therapy. However, despite many advances, current tests are not yet optimal: they either take hours or produce false-positive results. Researchers at Heidelberg University Hospital are now using AI in an approach that takes microRNAs from a blood sample to specifically diagnose ‘acute coronary syndrome’.

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.

Advanced therapy medicinal products: gene and cell therapies

Novel gene and cell therapies for treating incurable and hereditary diseases have raised high expectations. However, success has so far been limited to the long-established bone marrow transplants involving the administration of haematopoietic stem cells used to treat blood cancer. CAR T-cell therapies have recently emerged as a major new hope in cancer treatment.

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.
