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.

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.

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.

After a highly competitive process Ulm University has been awarded its fifth Collaborative Research Centre (CRC). The new CRC 1506 ‘Aging at Interfaces’ addresses one of the most urgent medical challenges of our time: the aging of the human body and the diseases and constraints that are frequently associated with the aging process.

At the University Hospital Tübingen, clinical evaluation of an in-house developed vaccine (CoVac-1) against SARS-CoV-2 was started in November 2020 under the direction of Prof. Dr. Juliane Walz in the CCU Translational Immunology of the Medical Clinic (Medical Director Prof. Dr. Helmut Salih). Now the results of the Phase I study are available and demonstrate a potent activation of the T-cell response against the coronavirus.

Treatment resistance is a central problem in the treatment of cancer. Bone and soft tissue tumors – known as sarcomas – in adolescents and young adults often stop responding to treatment too. This is because cancer cells develop a large number of new characteristics as the disease progresses and often become resistant to drugs that were originally effective.

Plastic products can be found everywhere in daily life, soft plastic in particular often being used for packaging or children's toys. These often contain so-called plasticizers which ensure that the material remains flexible. Because plasticizers are not bonded permanently to the plastic, they can escape from the material, meaning they can be absorbed by humans.

Acetate supports immune cells to fight against sepsis

Blood poisoning is the most dangerous complication of bacterial infections and often leads to death. Researchers at the Interfaculty Institute of Microbiology and Infection Medicine at the University of Tübingen have now identified acetate as a potent agent for stimulating innate immune system cells, supporting their ability to destroy bacteria.

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.

A team of engineers and biotechnologists at the University of Freiburg has for the first time shown in mammals that the concentration of antibiotics in the body can be determined using breath samples. The breath measurements also corresponded to the antibiotic concentrations in the blood. The team’s biosensor – a multiplex chip – will in future enable personalized dosing of medicines against infectious diseases on-site.

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.

Pharmacogenomics enables individualised drug prescription

Every person is unique, and their reaction to medications can be just as individual. For this reason, unexpected side effects occur time and again with common drugs, sometimes with life-threatening consequences. At the Dr. Margarete Fischer-Bosch Institute for Clinical Pharmacology (IKP) in Stuttgart, the influence of hereditary factors on these harmful reactions is being investigated in order to enable individualised therapies.

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.

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 risk of colorectal cancer can be predicted more accurately by determining seven blood-based micro-RNAs (miRNAs) than by using traditional methods - and can be done so many years before a diagnosis is made. In a current study, researchers from the German Cancer Research Center and the National Center for Tumor Diseases (NCT) Heidelberg show that miRNA profiles provide greater predictive accuracy than genetic or lifestyle-based risk…

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).

Individual operation risk assessment by the Cognitive Medical Assistant

Despite modern surgical techniques and anaesthetic procedures, serious complications can occur during surgical interventions. An interdisciplinary team at Heidelberg University Hospital has launched a project called the Cognitive Medical Assistant (German: Der Kognitive Medizinische Assistant, KoMed for short), designed to better assess the individual risk of these interventions. The project’s goal is to systematically and comprehensively analyse…

For the first time, scientists from the German Cancer Consortium (DKTK) partner site in Essen/Düsseldorf have discovered stem cells of the hematopoietic system in glioblastomas, the most aggressive form of brain tumor. These hematopoietic stem cells promote division of the cancer cells and at the same time suppress the immune response against the tumor.

Effective drugs for the treatment of diseases of the central nervous system do exist. However, the blood-brain barrier, which protects the brain as the body's control center, makes it especially difficult for therapeutic biomolecules to pass through. Thus, researchers from an international consortium coordinated by the Fraunhofer IGB have spent the last four and a half years developing a novel system in the EU project "N2B-patch"…

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.

Genetically enhancing a patient's immune cells by adding therapeutic genes to them outside the body is regarded as a promising new treatment approach in oncology. However, the production of these therapeutic cells using viruses is not only expensive but time-consuming. Researchers at the German Cancer Research Center (DKFZ) have developed an innovative non-viral vector that can efficiently introduce therapeutic genes into immune cells.

A new method allows stem cells and cancer stem cells to be studied at the single cell level and the resulting cell clones to be traced directly. Studying thousands of individual cells in parallel, the researchers combined the analysis of the genomic cancer mutations with the associated expression profiles.

Induced pluripotent stem cells (iPSC) are suitable for discovering the genes that underly complex and also rare genetic diseases. Scientists from the German Cancer Research Center (DKFZ) and the European Molecular Biology Laboratory (EMBL), together with international partners, have studied genotype-phenotype relationships in iPSCs using data from approximately one thousand donors.

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…

An international research team involving the universities of Paraná and Tübingen has developed a rapid test that can reliably identify Covid-19 antibodies in the blood within minutes. As the researchers report in the journal ACS Sensors, the new process is based on a simple measuring principle making it easy to carry out without expensive instruments, and is therefore suitable for use at mobile testing centers or by laboratories.

Gene accordions as potential markers for pathogenic properties

Bacteria must react to changes in the environment in order to survive. This is partly done by adapting genetic material, for example by multiplying and shortening individual genome segments. The research group led by Dr. Simon Heilbronner from the Interfaculty Institute of Microbiology and Infection Medicine at the University of Tübingen has shown that these so-called gene accordions are frequently found in the bacterium Staphylococcus aureus.

A rapid pyrogen test: the human immune system as model

Every year, around 11 million people die of sepsis (blood poisoning) caused by microorganisms or microbial residues, known as pyrogens, entering the bloodstream. The smallest amounts can trigger fever. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart have developed a pyrogen test that does not require a laboratory and is not tested on animals. It is expected to be placed on the market soon.

Multiple sclerosis - 12/03/2020

Direct application of biopharmaceuticals through the nose into the brain

There is currently no cure for multiple sclerosis, the most common neurological autoimmune disease in humans. Biopharmaceuticals that can delay the course of the disease or diminish its effects are often prevented from being fully effective by the blood-brain barrier. A European consortium led by the Fraunhofer IGB, Stuttgart is developing a new technology that can transport an innovative active ingredient directly to the central nervous system.

Researchers successfully rejuvenate the immune system in animal models

It is well known that stem cells age. Even the human immune system loses its power with age. Since all immune cells are derived from blood-forming stem cells, it is quite natural to associate the weakening of the immune system (immune senescence) with the ageing of blood-forming stem cells. Stem cell researchers and immunologists from the University of Ulm have now demonstrated the important role that blood-forming cells play in the ageing of the…
