Cell-based solution in place of animal testing - 05/06/2025

Innovative cell-based test to detect pyrogens in drugs

Drug safety testing for microbial contaminants and fever-inducing substances (pyrogens) still frequently uses animal experiments. InnoZell, a start-up that will soon be spun off from the University of Konstanz, has developed a compelling alternative: an animal-free, human cell-based assay that is faster, more sensitive and more reliable than traditional methods – and can be customised to meet user-specific needs.

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.

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.

Konstanz biologist Patrick Müller receives a Proof of Concept Grant from the European Research Council for his project "EmbryoNet-AI". Its goal is the further development of an AI-supported platform for the automated evaluation of experiments – for example, in drug development.

Research teams from the Universities of Konstanz and Potsdam are analyzing how proteins work together to enable our cells to both stick and move. The marker protein paxillin is at the centre of their interest.

How are proteins in our cells modified while they are still being synthesized? An international team of researchers from the University of Konstanz, Caltech, and ETH Zurich has deciphered the molecular mechanism of this vital process.

Why 3,000 bars are needed to take a comprehensive look at a protein: Konstanz researchers Frederic Berner and Michael Kovermann present a new high-pressure spectroscopy method to unravel the properties of proteins' native structures.

Computer scientists from the Cluster of Excellence Collective Behaviour developed a model, that explains how collective scenarios such as diseases may proceed.

Augmented reality for visual orientation - 15/11/2023

Fall prevention with the help of balance-enhancing AR glasses

As we age, our eyesight deteriorates and we have increasing difficulties with orientation. This can lead to balance problems and fatal falls. A team led by Dr. Lorenz Assländer from the University of Konstanz is currently developing a prototype of augmented reality (AR) glasses that use superimposed patterns to facilitate visual orientation in space, thereby helping to improve balance control and prevent falls.

So far, 4.2 million animal tests under the REACH chemical regulation: A study from Konstanz and Baltimore quantifies the number of animals that died for the hazard assessment of chemicals in the chemical industry.

Researchers from Konstanz and Zurich have deciphered a biochemical mechanism that ensures that newly formed proteins are processed correctly when they leave the cell's own protein factories. This solves a decade-old puzzle in protein sorting.

Researchers at the University of Konstanz publish image analysis software that automatically detects and classifies defects of animal development. Thanks to artificial intelligence, "EmbryoNet" outperforms human experts in terms of speed, accuracy and sensitivity.

Konstanz researchers discover the function of a previously unexplored protein: In three characteristic steps, "C12orf29" links the ends of RNA strands. Proteins that perform this kind of RNA ligation were previously unknown in humans. The results of the study suggest that it is important for RNA repair during cellular stress.

Inhibition of a protein complex in cells of the immune system prevents rejection of transplanted organs – this has been shown in a study by immunologists from the University of Konstanz, the Biotechnology Institute Thurgau (BITg) and Chongqing Cancer University Hospital.

Chemical building blocks from plastic waste; Reducing the risk of falls using virtual orientation aids: Konstanz chemists Manuel Häußler and Lukas Odenwald as well as sport scientist Lorenz Assländer receive Baden-Württemberg prototype funding for their transfer projects "Waste2DCA" and "Augmented Balance".

Using animal-free methods to assess the hazard potential of chemicals to the nervous system of unborn children? An international research team including toxicologists from Konstanz and Düsseldorf has developed a testing battery based on human cells that has the potential to replace traditional methods for assessing developmental neurotoxicity.

Toxicologists from the University of Konstanz have found that the protein p53 continuously protects our cells from tumorigenesis by coordinating important metabolic processes that stabilize their genomes.

3R-Center - 18/08/2021

Putting alternatives to animal testing into practice

Animal experiments are still central to biomedical research. However, it has become increasingly clear that not all of them are absolutely necessary. Alternative techniques exist. The new 3R-Netzwerk Baden-Württemberg is now seeking to promote these more vigorously - and improve animal welfare in cases where alternatives to animal testing are not available.

Chemical tools for biological applications

The boundaries between traditional scientific disciplines are becoming less and less distinct. Interdisciplinary cooperation is often required to study complex processes and biomolecular issues. Interdisciplinary cooperation is central to chemical biology.

Bachelors and masters under scrutiny has the new study system stood the test?

More practical relevance, shorter courses and courses that are compatible across Europe – when the decision to implement the bachelor’s and master’s system was made in Germany in 1999, there were high expectations and hopes for the positive changes to come. The question is, have these expectations been met?
