Different types of bone marrow stem cells give rise to blood and immune cells. A team led by Simon Haas now reports in ​“Nature Cell Biology” how that diversity develops. The findings could help improve stem cell therapies, including treatments for blood cancers.

Chronic myeloid leukemia (CML) is a type of blood cancer that arises from malignant changes in blood-forming cells of the bone marrow. It mainly occurs in older individuals and represents about 20 percent of all adult leukemia cases. A research team from the Institute of Molecular Medicine and Cell Research at the University of Freiburg has now demonstrated for the first time that mast cells play a crucial role in the development of CML.

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.

Germany's most important award for young scientists honors the development of immunotherapies against malignant brain tumors.

Estrogen does more than regulate reproduction — it helps brain cells handle stress. When levels decline after menopause, this ability is reduced, and these hormonal changes are believed to contribute to the increased risk of Alzheimer’s disease in women. MPI-IE researcher María José Pérez Jiménez has received the Klaus Tschira Boost Fund to investigate why — and whether these cellular responses can be restored.​

Not only actual chronological age, but also individual aging at the molecular level is a key factor in the development of cancer. This was discovered by scientists at the DKFZ and the Saarland Cancer Registry. If the so-called “epigenetic clocks” indicate accelerated biological aging, the likelihood of a cancer diagnosis increases. This finding could help identify at-risk groups and make early detection screenings more targeted

Whether we are predisposed to particular diseases depends to a large extent on the countless variants in our genome. However in the case of genetic variants the influence on the presentation of certain pathological traits has been difficult to determine. Researchers have introduced an algorithm based on deep learning that can predict the effects of rare genetic variants.

Alumnus Bastian Linder discusses the origin of this start-up and how a tRNA mechanism is helping scientists understand the importance and use of various RNA modifications as they pertain to disease.

An international research team involving the universities of Paraná and Tübingen has developed a rapid test that can reliably identify Covid-19 antibodies in the blood within minutes. As the researchers report in the journal ACS Sensors, the new process is based on a simple measuring principle making it easy to carry out without expensive instruments, and is therefore suitable for use at mobile testing centers or by laboratories.

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.

As cancer progresses, the tumor cells continually change, ultimately resulting in a tumor consisting of a large number of different cell clones with different characteristics. This is referred to as "tumor heterogeneity". In many cases, the cancer cells become resistant to the treatments available.

Apogenix, a biopharmaceutical company developing next generation immunotherapeutics, announced today that asunercept showed statistically significant benefits for hospitalized COVID-19 patients in the ASUNCTIS trial. The open-label multi-center phase II trial investigated efficacy and safety of asunercept in 435 patients with moderate to severe COVID-19 disease.

Neuroblastoma can spread relentlessly or shrink spontaneously. Scientists from the Hopp Children’s Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg and the National Center for Tumor Diseases (NCT) Heidelberg have shown that some malignant neuroblastomas employ a trick to avoid cell death: they use a special mechanism to lengthen the telomeres at the end of their chromosomes.

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

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.

Certain brain tumors in small children contain cells that develop very similarly to normal brain cells and others that have already developed malignantly, depending on where they are located within the tumor.

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.

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.

Using a new combination of three sensors and artificial intelligence, researchers at Heidelberg Medical Faculty of Heidelberg University and Heidelberg University Hospital are recognising patterns in babies' movements that show whether their nervous system is developing healthily.

In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps towards folding proteins into their correct three-dimensional structures. This discovery was made by an international research team led by scientists from the Center for Molecular Biology of Heidelberg University.

Chronic infections cause long-term changes in key immune cells. T helper cells suppress their immune function to ensure their survival. New targets for vaccines and cancer immunotherapies.

The neurosciences

In recent years, the neurosciences have increasingly made the leap from a purely basic science to applied research. Despite all this, basic research in south-west Germany is more diverse than ever. The discipline still has a number of breakthroughs to look forward to. The brain remains the most enigmatic human organ and one of the fascinating mysteries of the 21st century.

In multiple myeloma, a cancer of the bone marrow, relapse almost always occurs after treatment. Initially, most patients respond well to therapy. However, as the disease progresses, resistant cancer cells spread in the bone marrow, with fatal consequences for the patients.

Working with a new Emmy Noether Group, Dr. Pascal Schlosser is investigating how machine learning can aid in understanding the complex relationships between genes, proteins, and diseases.

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.
