SPI-MP: pioneer in personalised medical technology

Every person is unique – even when they are ill. This is why many approaches to personalised medicine have been under development. The Stuttgart Partnership Initiative - Mass Personalization (SPI-MP), which focuses on basic research into fabrication and biomaterial technologies for personalised biomedical systems, is at the heart of such research work. The projects range from artificial knee joint cartilage to state-of-the-art stroke diagnostics.

How do tumors react to a certain therapeutic approach? Knowing this before the start of a therapy would be of enormous value for people suffering from cancer as well as for the doctors treating them. Researchers have now made this very observation possible for the CAR-T cell therapy. This allows us to individually investigate how exactly these tumor cells react to the planned therapy.

An unexpected discovery surprised a scientist at the Max Planck Institute for Intelligent Systems in Stuttgart: nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment – much brighter than the actual contrast agent, the heavy metal gadolinium. Could diamond dust one day become a novel contrast agent used for MRI?

Cardiovascular diseases, including stroke and myocardial infarction, are the world's leading causes of mortality, accounting for over 18 million deaths a year. A team of KIT researchers has now identified a new cell type in blood vessels responsible for vascular growth. This discovery may allow for novel therapeutic strategies to treat ischemic cardiovascular diseases, i.e. diseases that are caused by reduced or absent blood flow.

In the medicine of the future, tiny robots will navigate independently through tissue and medical instruments will indicate their position inside the body during surgery. Both require doctors to be able to localize and control the devices precisely and in real time. Scientists from the German Cancer Research Center (DKFZ) have now described a signaling method based on an oscillating magnet that can significantly improve such medical applications.

More than seven million people in Germany suffer from diabetes. At the same time, research into drugs to treat this widespread disease is still difficult. Scientists led by Prof. Dr. Peter Loskill from the NMI Natural and Medical Sciences Institute and the Faculty of Medicine of the Eberhard Karls University of Tübingen have now developed a technique that significantly improves the view at the molecular and cell biological level in the pancreas.

Team involving the University of Freiburg has developed a new analytical method for the basement membrane in human lungs.

Scientists from the German Cancer Research Center (DKFZ) and Medical Faculty Mannheim of the Heidelberg University investigated in mice how spreading tumor cells behave at the site of metastasis: Some tumor cells immediately start to form metastases. Others leave the blood vessel and may then enter a long period of dormancy. What determines which path the cancer cells take is their epigenetic status.

Jun.-Prof. Dr. Priscilla Briquez, junior professor at the Department of General and Visceral Surgery at the Freiburg University Medical Center and member of the Medical Faculty at the University of Freiburg, has received a European Research Council (ERC) Starting Grant from the European Commission. Her DRESSCODE project will receive a total of 1.5 million euros funding for five years.

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.

How can camera images be used during minimally invasive surgeries to assess whether the operated organ is sufficiently perfused with blood? Scientists from the German Cancer Research Center (DKFZ) and the Städtisches Klinikum Karlsruhe have now succeeded in automatic monitoring of ischemia during a kidney surgery using only the optical properties of the tissue and not relying on injection of contrast agent.

Photon-counting technology - 01/02/2023

PC3 consortium: innovative computed tomography for Baden-Württemberg

The University Hospitals of Freiburg, Tübingen and Mannheim have been cooperating with each other since 2021 to test new types of computed tomography devices. With the help of photon-counting technology, the aim is not only to improve patient care, but also to encourage local companies to develop downstream data processing technologies.

DZNE researchers discover link between the protein medin and Alzheimer's disease. The protein medin is deposited in the blood vessels of the brains of Alzheimer's patients along with the protein amyloid-β. DZNE Researchers have discovered this so-called co-aggregation. They have now published their observation in the renowned journal Nature.

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.

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.

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.

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.

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.

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.

The mechanisms by which the body measures temperature and regulates its own body heat are vital, but still poorly understood. The discovery of the first heat sensor on nerve cells in the skin, for which the U.S. molecular biologist David Julius received this year's Nobel Prize for Medicine, was therefore pioneering.

Cyber Valley researchers have created medical educational tools that could potentially train the surgeons of the future, much like flight simulators train pilots. The team developed a range of artificial organ phantoms to serve as training platforms for surgeons. Thanks to the structured data of experienced medical professionals, a quantitative and objective assessment of a trainee’s skills can be assessed in real time.

On the one hand, blood vessels supply tumors with nutrients and, on the other, enable cancer cells to spread throughout the body. The settlement of circulating tumor cells in a distant organ is promoted by factors whose production is induced by the primary tumor itself. Scientists have now identified a new growth factor produced by blood vessels that enables tumor cells to metastatically colonize organs.

The bacterium Staphylococcus epidermidisis primarily a harmless microbe found on the skin and in the noses of humans. Yet some strains of this species can cause infections – in catheters, artificial joints, heart valves, and in the bloodstream – which are difficult to treat. These bacteria are often resistant to a particularly effective antibiotic, methicillin, and are among the most feared germs in hospitals.

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.
