The results of a Tuebingen-led study raise hope that a newly developed drug could herald a new era in oncological liver surgery and transplantation. The drug could even have the potential to significantly improve the treatment of acute and chronic liver diseases. The drug candidate "HRX-215" is a so-called MKK4 inhibitor, i.e. the drug inhibits the MKK4 protein found in liver cells and thus leads to an increase in the regeneration of…

opto biolabs: how frustration and inventiveness led to the establishment of a company

When she found she had no suitable illumination devices for her doctoral thesis, Dr. Kathrin Brenker simply created her own customised adapters and founded a company called opto biolabs. Now, Brenker and company co-founder Luis Köbele sell two different types of devices. The main goal is to equip laboratories with illumination technologies that allow optogenetics methods to be used to accelerate development of optogenetic therapeutics.

CureVac N.V., a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (mRNA), today announced the publication of preclinical data demonstrating that their COVID-19 vaccine candidate, CVnCoV, protects against challenge infections with the SARS-CoV-2 Variant of Concern B.1.351 and a strain of the original SARS-CoV-2 B1 lineage (BavPat1) in a transgenic mouse model.

Artificial intelligence (AI) can help dermatologists to detect skin cancer. However, many dermatologists distrust the algorithms' decisions, which they cannot comprehend. Scientists at the German Cancer Research Center have now developed an AI-based support system for skin cancer diagnostics that explains its decisions.

The European Commission has launched a new strategy to make Europe the most attractive place in the world for life sciences by 2030. Life sciences – the study of living systems, from cells to ecosystems – are central to our health, environment and economy. They drive innovation in medicine, food and sustainable production, adding nearly €1.5 trillion in value to the EU economy and supporting 29 million jobs across the Union.

Sepsis is one of the most dangerous medical emergencies. The condition is the result of a misdirected immune response to an infection, which can quickly lead to organ failure and death. Every hour counts – but early detection is difficult. A new study from Heidelberg now presents an innovative approach: artificial intelligence (AI) and hyperspectral imaging of the skin enable immediate and non-invasive sepsis diagnosis directly at the bedside.

University of Tübingen research team observes biochemical process in living cells – indications of new approach to preventing heart attacks and strokes

Heidelberg scientists decode the genetic foundations of rapid testicle evolution in mammals and humans. Evolutionary pressure across male mammals to guarantee the procreation of their own offspring led to a rapid evolution of the testicle.

The health of nerve cells is closely linked to the auxiliary cells that surround them, the so-called glial cells. It still remains largely unknown what role glial cells play in age-related diseases.

Targeted molecular interventions in the replication cycle and the immune recognition of viruses are intended to prevent viral entry into cells and virus replication. Scientists work on new approaches to combating highly dangerous viral diseases such as yellow fever or Lassa fever. The European Union is supporting the project over a period of five years to the tune of just under eight million euros.

On the basis of the cooperative relations that have developed over time, Heidelberg University and Harvard University are going to deepen and expand their cooperation. They have signed a Memorandum of Understanding to that effect. As an institutional internationalization project, the state of Baden-Württemberg is providing ten million euros to support this initiative, which is part of the state’s “Global Partnership in Science” activities.

Initial Phase 1 part started with multivalent modified mRNA influenza vaccine candidates. Candidates developed in collaboration with GSK within broad infectious disease vaccine program encode for antigens covering four WHO-recommended flu strains.

Freiburg-Prague research collaboration achieves scientific breakthrough in understanding cell division. The international research collaboration has uncovered a new mechanism of the crosstalk between microtubules and actin cytoskeleton during cell division and revealed unique characteristics of the previously unexplored protein FAM110A.

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).

Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-sized microrobots individually and at high resolution in a living organism. This is an important step towards precise control of the robots and their clinical translation.

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.

With mice, researchers showed that experimentally induced lack of blood flow in the brain epigenetically reprograms astrocytes into brain stem cells, which in turn can give rise to nerve progenitor cells. This discovery shows that astrocytes could potentially be used in regenerative medicine to replace damaged nerve cells.

In order to develop approaches for the prevention and treatment of Alzheimer's dementia in clinical trials, it would be helpful to be able to identify people with a particularly high risk of developing the disease. But which biomarkers can indicate an increased likelihood of disease early on in symptom-free people who actually develop Alzheimer's later?

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

Researchers at the University of Freiburg, together with partners, have uncovered the mechanism of ultrafast transport by calcium pumps in nerve cells. These pumps, complexes of PMCA2 and neuroplastin proteins, operate at more than 5,000 cycles per second and terminate calcium signals within milliseconds – 100 times faster than previously known. They play a crucial role in rapid information processing in the brain.

An imaging technique developed by Freiburg researchers provides insights into cardiac arrhythmias that can cause sudden cardiac death in animal models. The changes discovered could explain why even seemingly healthy people are sometimes affected.

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.

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.

CAR-T cell therapy is a last hope for many patients with blood, bone marrow or lymph gland cancer when other treatments are unsuccessful. A limiting factor of this very effective and safe therapy is that the cells used in the process quickly reach a state of exhaustion. Researchers at the University of Freiburg have now been able to prevent this exhaustion and thus significantly improve the effect of the therapy in a preclinical animal model.

Zebrafish can completely replace damaged heart muscle cells: The affected organ becomes fully functional again. Researchers at Ulm University have discovered that a specific cell-to-cell communication signal helps them to cope better with replication stress. This stress inhibits tissue regeneration in humans and mammals as they age. In Zebrafish a signalling protein ensures that the cells of the damaged organ continue to divide and thus multiply.
