New treatment methods: DNA origami-based nanodevices precisely control immune response - 24/04/2025

Mit Bottom-up-synthetischer-Immunologie zu neuartigen Therapieansätzen

Moderne Therapien zur Bekämpfung von Infektionskrankheiten oder Krebs beziehen zunehmend das körpereigene Immunsystem ein. Mithilfe innovativer Bottom-up Ansätze auf dem Gebiet der synthetischen Immunologie wollen Forschungsgruppen nun neue Behandlungsverfahren entwickeln, mit denen sich die Immunantwort präziser lenken lässt. Bei der Erkennung und Bekämpfung von Erregern oder Krebszellen benötigt unser Immunsystem gelegentlich Unterstützung.

Individuals with a genetic predisposition to Alzheimer’s disease show altered blood levels indicating damaged neuronal contacts as early as 11 years before the expected onset of dementia symptoms. This is evident in the levels of the protein “beta-synuclein”. An international team report these findings in the journal “Alzheimer’s & Dementia”. The biomarker studied here could potentially help to detect neurodegeneration at an early stage.

The human brain continuously processes sensory impulses that compete for our attention. Our ability to select enables us to process specific information and ignore irrelevant stimuli. In this way, we can recognize a familiar face in a large crowd of people. But how is this made possible?

Contact with pets reduces the risk of developing stress-related disorders in adult life in urban children. This is the conclusion of a study conducted by the Section for Molecular Psychosomatic Medicine at Ulm University Hospital together with other researchers from Germany and the USA. Living with animals is said to alleviate inflammatory stress reactions.

Melanie Börries, Professor of Medical Bioinformatics at the Medical Faculty of the University of Freiburg and Director of the Institute of Medical Bioinformatics and Systems Medicine at the Medical Center – University of Freiburg, is being honoured for her pioneering work in personalised cancer therapy.

Baden-Württemberg AI Alliance - 08/04/2025

Achieving widespread use of AI

Artificial intelligence presents both opportunities and risks. The Baden-Württemberg AI Alliance is dedicated to fostering collaboration among AI stakeholders to ensure that AI solutions deliver tangible benefits to citizens and businesses across the state. The alliance will also place greater emphasis on advancing AI applications within the healthcare sector.

The Medical Faculty Heidelberg of Heidelberg University and Mannheim University of Applied Sciences are combining their expertise in infectious disease research, mass spectrometry, and bioinformatics to overcome resistance in malaria vectors. The project is supported by funding from the Gates Foundation.

Metastatic breast cancer requires complex and lengthy treatment, the side effects of which affect the quality of life of patients. These often include sexual problems. In a large international randomized exercise intervention trial, researchers have now shown that women who received a nine-month supervised exercise program reported significantly fewer symptoms than women who did not participate in the training program.

Germany's most important award for young scientists honors the development of immunotherapies against malignant brain tumors.

Researchers from the universities in Konstanz and Vienna discover a new class of antibiotic that selectively targets Neisseria gonorrhoeae, the bacterium that causes gonorrhoea. These substances trigger a self-destruction program, which also operates in multi-resistant variants of the pathogen. The novel findings are published in the current issue of Nature Microbiology.

84 percent of Germans consciously consider their diet. For the majority, nutrition is a central topic, but many perceive the public debate as divisive and patronising. According to the latest nutrition study by the Robert Bosch Stiftung and the More in Common, citizens want policies that promote healthy, regional, and affordable food – without regulations or bans. At the same time, they are calling for more say in shaping the food system.

Two molecular control factors play a decisive role in what is known as splicing, the cutting and assembly of mature messenger RNA – a prerequisite for protein synthesis in the cell. The poorly characterized factors are crucial to ensuring that the molecular machine responsible for splicing is working correctly. A research team has deciphered how the two cellular quality inspectors work.

SpecPlate: an innovative multiwell plate - 26/03/2025

Focus on innovative drug development - accurate, time- and cost-saving

Drug research is a complex and costly process that requires extensive laboratory analyses and vast quantities of consumables, with disposable sample carriers in particular being used in their millions. PHABIOC GmbH has come up with a solution in the form of the SpecPlate, a ground-breaking alternative to sample carriers that reduces the time taken to perform analyses as well as the quantity of materials consumed. Serial production is underway.

Researchers at the German Cancer Research Center (DKFZ) have succeeded in identifying a resistance mechanism that often occurs in a specific targeted therapy against chronic lymphocytic leukemia (CLL). The drug ibrutinib is effective in many cases, but therapy resistance often develops during the course of treatment. In cell culture experiments and in mice, the resistance mechanism was successfully overcome using a second drug.

A recent article by Prof. Dr. Martin Haimerl and Prof. Dr. Christoph Reich of Furtwangen University shows that machine learning (ML) in medicine is often evaluated without a comprehensive risk assessment. The authors investigated the extent to which current scientific papers include risk-based metrics in the evaluation of AI models for medical devices.

Using artificial intelligence to revolutionize drug development is the aim of the start-up "EmbryoNet AI Technologies" led by Konstanz biologist Patrick Müller. Müller and his team have now been awarded the start-up prize by the Federal Ministry for Economic Affairs and Climate Action (BMWK) for their business concept.

Stomach ulcers, gastritis and even stomach cancer are often the result of an infection with Helicobacter pylori. If the bacterium remains unrecognised for a long time, this can have serious consequences. Researchers have now developed a miniaturisable sensor system for the mobile analysis of breath that is effective, fast and inexpensive. The research team uses a biological survival trick of the stomach germ to detect the bacterium.

The weight of expectant mothers could play a role in the development of acute lymphoblastic leukemia (ALL) in daughters – but not in sons. This has been shown by researchers at the German Cancer Research Center (DKFZ).

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.

Scientists at the Max Planck Institute for Intelligent Systems developed a single-cell green microalgae coated with magnetic material. This miniature robot was put to the test: would the microalgae with its magnetic coating be able to swim through narrow spaces and, additionally, in a viscous fluid that mimics those found in the human body? Would the tiny robot be able to fight its way through these difficult conditions?

With the goal of creating living cells from non-living components, scientists in the field of synthetic biology work with RNA origami. This tool uses RNA biomolecule to fold new building blocks, making protein synthesis superfluous. In pursuit of the artificial cell, a research team has cleared a crucial hurdle. Using the new RNA origami technique, they succeeded in producing nanotubes that fold into cytoskeleton-like structures.

University of Tübingen research team shortens the search for attackers that can wipe out multiresistant pathogens – with the aim of treating infections without antibiotics
