Using organoids to gain a better clinical understanding of pancreatic cancer

Prof. Dr. Alexander Kleger carries out translational research at Ulm University Hospital to gain a better understanding of pancreatic ductal adenocarcinoma (PDAC) and develop individualised treatments. He and his team are using organoid models and stem cell-based systems and have succeeded in simultaneously cultivating all three main cell types of the pancreas from pluripotent stem cells.

The nuclease Cas13b associated with the CRISPR gene scissors, which is an enzyme that degrades nucleic acids, has the potential to be used in the future in hereditary diseases to switch off unwanted genes. In the fight against infections, this nuclease is also being researched as an antiviral agent, as Cas13b can specifically intervene in the genetic material of viruses and render them harmless.

An Emmy Noether junior research group at Heidelberg University is investigating how to gain new insights into fundamental biological mechanisms from large-scale molecular data sets. Led by Junior Professor Dr Britta Velten, it has started work at the Centre for Organismal Studies and the Interdisciplinary Center for Scientific Computing.

In the PRECISION-ImmunoRad project, a multidisciplinary team of scientists from Heidelberg, USA, and Cyprus will unite their expertise to develop novel curative therapeutic strategies for currently hard-to-treat cancers. These strategies will integrate high-precision ion beam therapy with genetically engineered immune cells therapies (CAR-T cells), personalized cancer vaccines, and the targeted reprogramming of the tumor immune microenvironment.

Regenerative medicine makes use of patients own resources

Die Regenerative Medizin bietet neue Therapieoptionen quer durch die ärztlichen Fachgebiete. Zumeist sind es zellbasierte Verfahren und sie werden häufig mit innovativen Biomaterialien kombiniert. Regenerative Therapien vereinen Know-how aus den Biowissenschaften mit moderner Medizintechnik und sie profitieren von den Fortschritten in den Ingenieur- und Materialwissenschaften.

The Damietta Server broadens the accessibility to protein design research and its applications in various biotechnological and biomedical fields. Researchers at the Max Planck Institute for Biology Tübingen, the University of Tübingen, and the University Hospital Tübingen have developed a web-based toolkit to accelerate and simplify protein design without needing powerful computers or extensive protein design expertise on the user’s end.

Immunotherapies have greatly improved the treatment of metastatic melanoma, but they can cause serious side effects. A study led by researchers from Heidelberg University's Medical Faculty, the Heidelberg University Hospital, and the NCT in Heidelberg now shows that autoantibodies detected in the blood before the start of therapy could help to better assess the individual risk of side effects in patients.

Led by researchers from Heidelberg Faculty of Medicine at Heidelberg University and the University of California, San Francisco (USA), an international research team has evaluated a novel approach for the diagnosis of pulmonary tuberculosis. The method enables detection of Mycobacterium tuberculosis without laboratory infrastructure, within a markedly shorter time frame than conventional diagnostics, and using a simple swab.

Antibodies can improve the rehabilitation of people with acute spinal cord injury. Researchers at 13 clinics in Germany, Switzerland, the Czech Republic and Spain have investigated this with promising results. For the first time, it was possible to identify patient groups that displayed a clinically relevant treatment effect. A follow-up study will start in December 2024.

Researchers of the University of Freiburg introduce biosensor for the nucleic acid amplification-free detection of SARS-CoV-2 RNA.

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.

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.

On March 23, 2022, the U.S. Food and Drug Administration (FDA) granted approval to the first targeted radioligand therapy against metastatic prostate cancer based on a joint patent of the German Cancer Research Center (DKFZ) and the University of Heidelberg. The agent significantly improves the chances of survival for those affected.

Proteins have characteristic amino acid sequences, the analysis of which is fundamental for research and medicine. These can be decoded; however, so-called protein sequencing is expensive and time-consuming. A large-scale research project led by Prof. Dr. Jan Behrends from the Institute of Physiology at the University of Freiburg now aims to establish a new technology for protein sequencing using nanopores, which will be rapid and cost-effective.

Known as the power plant of the cell, mitochondria are essential to human metabolism. Human mitochondria consist of 1,300 different proteins and two fatty biomembranes. The vast majority of mitochondrial proteins are produced with a cleavable transport signal and have to be actively transported into the mitochondria.

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

A building with 7400 m² of research space for robotics and artificial intelligence is being built on the Max Planck Campus in Büsnau. Researchers from the Max Planck Institute for Intelligent Systems (MPI-IS) and the University of Stuttgart will be working there with partners from science and industry as well as start-ups from 2027.

For the first time, the active substance epifadin has been isolated at the University of Tübingen – Epifadin is produced by specific bacteria in the nose and on the skin of humans, has an antibiotic effect, and is the first example of a previously unknown antimicrobial compound class.

The cellular environment of a tumor can either support or sabotage recovery. The most comprehensive study to date on the tumor microenvironment in low-grade gliomas, conducted by KiTZ, Jena University Hospital, the DKFZ, and Heidelberg University Hospital, shows what a supportive or obstructive “neighborhood” looks like in childhood brain tumors. The study also provides clues as to how tumor communication might be blocked.

For the first time, researchers have succeeded in mapping the organization of immune cells in human lymph nodes. The study was led by scientists from Heinrich Heine University Düsseldorf, Düsseldorf University Hospital, the DKFZ, the European Molecular Biology Laboratory (EMBL), and the Max Delbrück Center (MDC) in Berlin. They were able to demonstrate why the architecture of healthy lymph nodes is altered in malignant lymphomas.

Researchers of the University of Freiburg have discovered a previously unknown function of septins in defending cells against dangerous hospital pathogens.

University of Tübingen neuroscientists discover new functions of head-direction cells suggesting they may contribute to episodic memory formation.

The Baden-Württemberg Ministry of Science, Research and Arts (MWK) is supporting medical researchers at Ulm University with start-up funding totalling 600,000 euros. The aim is to establish an EU consortium for the broad therapeutic use of mesenchymal stromal cells. The funding is being awarded as part of the "BEGIN - Participation in major European projects and initiatives" programme.

A new molecular engineering technique can precisely influence the development of organoids. Microbeads made of specifically folded DNA are used to release growth factors or other signal molecules inside the tissue structures. This gives rise to considerably more complex organoids that imitate the respective tissues much better and have a more realistic cell mix than before.

Researchers at the Hopp Children's Cancer Center Heidelberg, the German Cancer Research Center, the Heidelberg Medical Faculty of Heidelberg University, and Heidelberg University Hospital have taken a decisive step toward more precise diagnosis of brain tumors. The latest version of the AI-based Heidelberg CNS Tumor Methylation Classifier can identify more than 180 tumor types —twice as many as the previous version.
