An international team led by Professor Tobias M. Böckers from Ulm University Medical Centre has been awarded up to 1.7 million euros to develop a novel therapy for a rare, syndromic form of autism. The research project focuses on a gene whose loss of function can manifest itself in severe impairments in language, behaviour and everyday functions of those affected.

Depending on whether the cell nucleus of an epithelial cell is located on the outer or inner side of the tissue, the genome is more or less acetylated - genes can therefore be translated easier or harder. Scientists from the German Cancer Research Center (DKFZ) have demonstrated this for the first time in the development of the Drosophila wing.

Heidelberg scientist Dr Venera Weinhardt has received an ERC Synergy Grant for a pioneering biomedical research project. The European Research Council (ERC) is granting this funding to advance soft X-ray microscopy. This imaging technique along with other innovations will be used to investigate the hepatitis E virus.

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.

Diabetics have a higher risk of colorectal cancer and often a poorer prognosis after developing the disease. The biological mechanisms behind this association were largely unknown. A research team at the German Cancer Research Center (DKFZ) has now discovered that tumors with a low number of immune cells appear to be particularly susceptible to the harmful effects of diabetes.

With the FeMEA project – Ferroelectric Microelectrodes for Biomedical Applications – Hahn-Schickard is setting a pioneering course in bioelectronics research. The aim of the project is to develop novel microelectrode arrays in which ferroelectric materials are used as functional interfaces in CMOS chips for the first time.

In the current selection round, the German Research Foundation (DFG) has granted funding for two new Collaborative Research Centres at the University of Konstanz. Over the next four years, the research teams will be working intensively on trigger signals in biological cells as well as on "silence" and "noise" in human speech.

A key molecular mechanism drives the growth of liver cell cancer while simultaneously suppressing the body's immune response to the tumor. This has now been published in the journal Nature by a team led by researchers from the DKFZ, the UKT, and the Sanford Burnham Prebys Medical Discovery Institute. However, the results also show that this very mechanism could help identify patients who respond particularly well to immunotherapy in the…

VDI Guideline 5708 “Bioprinting, methods and definitions”: What sounds technical and sober at first glance is an important step forward in the future field of 3D bioprinting. The guideline was developed under Dr. Hanna Hartmann from the NMI in Reutlingen and Prof. Dr. Jürgen Groll from the University Hospital of Würzburg. It creates a binding, practical basis for reproducible and quality-assured bioprinting procedures.

Optogenetics switching cell activity on and off with light

What still sounds like science fiction to the general public has long been within reach for many years scientists have been able to manipulate neural activity selectively with light. They use different wavelengths to turn cells on and off as if they were a standard switch. Optogenetics is an emerging technology that combines optics and genetics. The technology is already used in many different ways for many different purposes by numerous research…

Atriva Therapeutics - 21/10/2020

COVID-19 pioneer drug in Phase II clinical trial - with double the power

The effective treatment of people with severe COVID-19 is a major goal during the corona pandemic. ATR-002, an oral small molecule that targets RNA viruses such as influenza virus and SARS-CoV-2, has a dual effect: it impairs viral propagation and also has an immunomodulatory effect. And what’s more, due to its unique cellular mechanism of action, the efficacy of Atrivia Therapeutics’ drug candidate is not reduced by virus mutations and…

Together with colleagues from Israel and USA, HITS researcher Frauke Gräter investigates the effects of physical force on the collagen protein in two different animal model systems. Their goal is to measure the effects of mechanoradicals on the integrity of the tissue and the well-being of the organism, with impact on health and aging.

Researchers at the Medical Faculty of Heidelberg University and the Heidelberg University Hospital have used modified rabies viruses to label glioblastoma tumour cells and their direct cell contacts in the mouse brain. The new method showed that the tumour cells are connected to different types of nerve cells throughout the entire brain at a very early stage of the disease.

Cell division, cell differentiation, cell repair and cell death play fundamental roles in the human organism, its development, health and reproduction. Cellular transformation processes are governed by two regulatory mechanisms: chromatin modifications and cell signaling networks. The EpiSignal Research Training Group sheds light on the hitherto little-researched interplay between these two complex systems.

Many people with cancer experience dramatic loss of muscle and fat tissue. In many cases, even the heart muscle is affected. This wasting syndrome, affects around half of all cancer patients. Researchers from Helmholtz Munich, in collaboration with Heidelberg University Hospital, the Technical University of Munich, and the German Center for Diabetes Research, have now identified a previously overlooked driver of cachexia: the liver.

A team from the DZHK sites in Heidelberg/Mannheim and Berlin has discovered that a single enzyme in the heart plays a key role in determining whether the organ develops in a healthy manner. If this molecular protective factor is missing, serious congenital heart defects can develop.

It has only recently become known that two parallel systems of blood formation exist in the body. Researchers at the DKFZ have developed a method to examine both systems separately in mice for the first time. Their surprising finding: the majority of immune cells do not originate from classic blood stem cells in the bone marrow, but from precursor cells that are independent of blood stem cells and are already present in the embryo.

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein synthesis right at the start. An international research team with significant involvement of Konstanz biologists has now discovered what underlies this previously unknown function of NAC.

Christiane Opitz, scientist at the German Cancer Research Center, is being awarded this year's Ita Askonas Prize of the European Federation of Immunological Societies. Opitz has discovered how tumor cells use certain metabolites to protect themselves against the immune system. Her research findings may provide important clues for the development of new therapeutic concepts.

University of Tübingen team discovers how malformations of the blood vessels can occur in mice – yielding information with possible ramifications for retinal disease.

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 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.

Chronic inflammatory bowel diseases - 25/09/2024

Proinflammatory regulatory T lymphocytes as a therapeutic target in Crohn's disease

Chronic inflammatory bowel diseases are very stressful for those affected and increase the risk of bowel cancer. PD Dr. Robyn Laura Kosinsky from the Bosch Health Campus in Stuttgart, together with researchers from the USA, identified disfunctional regulatory T cells as important drivers of inflammation in Crohn's disease. They also found that with the help of an epigenetically active drug, it was possible to restore the cells’ original…

A research team from Freiburg and Frankfurt has discovered how cells recognise and internally break down waste. The results are relevant for the development of therapies for diseases such as Alzheimer’s.

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.
