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’.

Laboratory automation - 29/11/2021

Reaching the goal quickly and efficiently with the help of artificial intelligence

Medical research is slow, costly and time-consuming. The system developed by the start-up LABMaiTE could soon change that. With the help of artificial intelligence, it will be possible to automate laboratory experiments and collect and analyse data at the same time.

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.

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.

In multiple myeloma, a cancer of the bone marrow, relapse almost always occurs after treatment. Initially, most patients respond well to therapy. However, as the disease progresses, resistant cancer cells spread in the bone marrow, with fatal consequences for the patients.

As cancer progresses, the tumor cells continually change, ultimately resulting in a tumor consisting of a large number of different cell clones with different characteristics. This is referred to as "tumor heterogeneity". In many cases, the cancer cells become resistant to the treatments available.

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.

Scientists of the Translational Lung Research Center Heidelberg (TLRC) and the German Cancer Research Center (DKFZ) have discovered a new link between excessive airway mucus and chronic airway inflammation that is characteristic of cystic fibrosis and chronic obstructive pulmonary disease (COPD). The researchers showed that mucus in the airways reprograms certain cells of the immune system.

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.

Parkinson's disease is characterised by a slow, progressive loss of nerve cells in certain brain areas. The disease is still incurable and the exact causes are unclear. The dopamine deficiency in the brain can only be controlled to some extent in the initial phase of the disease. Basic research is being conducted in an attempt to unravel the mystery of Parkinson's disease.

Furtwangen University publishes the world’s first molecular biological study on bacterial contamination of slit lamps. Slit lamps are among the most important tools used by ophthalmologists and opticians. They allow selected areas of the eye to be magnified and examined for diseases.

Viral zoonoses - 24/01/2022

Development of inhibitors that help stop viral zoonoses

Emerging viral infections such as COVID-19 or Zika disease pose an increasing threat to humans. At the Institute of Pharmacy and Molecular Biotechnology (IPMB) at Heidelberg University, Prof. Dr. Christian Klein's research group is developing inhibitors against already known viruses in the hope that these can also be used against new virus variants.

The International Agency for Research on Cancer (IARC), an agency of the World Health Organization (WHO), will soon publish the first edition of its classification of childhood cancers. The new WHO classification forms the basis of modern, precise cancer diagnostics for physicians and pediatric oncologists worldwide and is based on the latest international research findings.

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.

Genetic alterations that promote the development and spread of tumors are difficult to identify. This is especially true for mutations in the non-protein-coding regions of the genome, which include all important regulatory sequences. Scientists at the German Cancer Research Center have now published an algorithm that detects cancer drivers in both the protein-coding and non-coding regions of the genome.

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.

A new interdisciplinary research project aims to uncover information that can help decode hereditary colon cancer with the aid of mathematical models. Mathematicians and tumour biologists of Heidelberg University, the Heidelberg Institute for Theoretical Studies, Heidelberg University Hospital, and the German Cancer Research Center are collaborating on the project.

Today, the EU Parliament adopted the EU Regulation on Health Technology Assessment (HTA), which includes not only new medicines (including gene and cell therapies), but also medical devices.

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.

The cochlear implant (CI) is the most successful neural prosthesis worldwide. Thanks to direct stimulation of the auditory nerve, it enables more than half a million people worldwide to hear, even though those affected were born deaf or deafened.

5G-OR is one of the 4 winning projects jointly selected by the Federal Ministry of Economics and Climate Action in Germany and the Ministry of Economy, Finance and Relaunch in France for the call “Technical developments and application ecosystems for 5G private networks”. The joint Franco-German 5G-OR project takes up the challenge in the healthcare domain.

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.

The incidence of colorectal cancers in young adults is increasing. At the same time, the proportion of overweight and obese young people is also on the rise. Whether there is a connection between these two observations, however, was not known until now. Scientists at the DKFZ have now shown that the risk of early colorectal cancer is significantly increased in overweight young people compared to normal-weight peers.

Drugs consist of molecules developed in the drug laboratory that bind to their target, usually a protein, and thus exert their effect. The actual duration of binding of a drug molecule to its target protein varies depending on the drug. The lifetime of the drug-target complex can play a critical role in the efficacy of a drug, as a long residence time at the target can be crucial for the drug's action in some cases.
