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.

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.

A protein with contradictory properties: Despite its large negative surface charge, it has a strong tendency to take up electrons, which are also negatively charged. The researchers discovered positively charged calcium ions inside the protein very near the electrons, counteracting their charge. They see this as a natural way of handling opposing electrical charges and allowing the protein to optimally fulfill its biological function.

Pancreatic cancer is fueled by connections to the nervous system. This is reported by scientists from the German Cancer Research Center (DKFZ) and the Heidelberg Institute for Stem Cell Technology and Experimental Medicine (HI-STEM)*. The team discovered that the tumor reprograms the neurons for its own benefit.

A guardian molecule ensures that liver cells do not lose their identity. The discovery is of great importance for cancer medicine because a change of identity of cells has come into focus as a fundamental principle of carcinogenesis for several years. The research team was able to show that the newly discovered guardian is so powerful that it can slow down highly potent cancer drivers and cause malignant liver tumors to regress in mice.

Researchers of the Heidelberg University, Heidelberg University Hospital (UKHD) and Heidelberg Institute for Theoretical Studies (HITS) have developed a synthetic peptide based on the natural protein S100A1, a nearly universal “fuel” for weakened hearts. The researchers combined computer-aided methods with lab studies to investigate the therapeutic effect of the so called S100A1ct peptide molecule.

Scientists from the German Cancer Research Center (DKFZ) and ShanghaiTech University have developed an innovative method for growing brain tumors of individual patients in the laboratory that mimic the original structure and the molecular property of the parental tumor as closely as possible. Drug tests in this model were found to correlate very well with actual patient responses, making it a valuable method for investigating therapies.

In collaboration with Heraeus, the German Institutes of Textile and Fiber Research (DITF) are developing fibers and textiles with a novel infection protection system. The basis is an antimicrobial mechanism of action licensed from Heraeus and marketed under the name AGXX. The goal of the collaboration is to optimally integrate the AGXX technology into textile finishes and coatings and to incorporate it into fiber-spinnable polymers.

The spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a basic requirement for producing proteins. Researchers at the Heidelberg University Biochemistry Center (BZH) have succeeded for the first time in depicting a faultily “blocked” spliceosome at high resolution and reconstructing how it is recognized and eliminated in the cell.

A research team from the Heidelberg Medical Faculty, the German Cancer Research Center, the Berlin Institute of Health at Charité (BIH) and the Max Delbrück Center has discovered new details about the spread of the incurable bone marrow cancer multiple myeloma in the body: When the cancer cells break out of the bone and multiply outside the bone marrow, a wide variety of tumor cells arise, accompanied by a significantly altered immune response.

Like all viruses, the Ebola virus is dependent on host cells in order to replicate. Researchers at Heidelberg University Hospital, in collaboration with colleagues from the Friedrich Loeffler Institute, have been able to show for the first time using state-of-the-art imaging techniques how the replication compartments of the Ebola virus change during replication in infected cells.

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.
