MHH molecular physician Professor Dr. Dr. Schambach wants to use genetically modified natural killer cells to find new therapeutic options against three particularly malignant cancers. The EU is funding the project with 3.8 million euros. Natural killer cells (NK cells) are part of the first line of defense of our immune system. They eliminate virus-infested cells and tumor cells. This makes NK cells interesting helpers in cancer therapy. Professor Dr. Dr. Axel Schambach, head of the Institute of Experimental Haematology…
In the ADIUVO clinical trial, Professors of Internal Medicine and Endocrinology Massimo Terzolo (University of Turin, Italy) and Martin Fassnacht (University of Würzburg) and their teams were able to demonstrate that not all patients with adrenocortical carcinoma require the previous standard therapy Mitotane after complete tumour resection. In 2017, the teams of Massimo Terzolo and Martin Fassnacht published a study in the New England Journal of Medicine that provided evidence for the efficacy of Mitotane in the prevention of recurrence…
In MS patients, misdirected immune cells damage the sheaths of the nerve cells in the brain. Researchers at the MHH have discovered a mechanism by which these can be repaired with the help of a sugar compound produced naturally in the body. Multiple sclerosis (MS) is an inflammatory autoimmune disease of the central nervous system (CNS). In Germany, more than 280,000 people are affected. In most cases, MS progresses in relapses, which occur completely irregularly as excessive inflammatory reactions in…
Cooperation between the University of Bonn, the USA and the Netherlands cracks the mode of action of clovibactin. More and more bacterial pathogens are developing resistance. There is an increasing risk that common drugs will no longer be effective against infectious diseases. Researchers from the University of Bonn, the German Center for Infection Research (DZIF), Utrecht University (Netherlands), Northeastern University in Boston (USA) and the company NovoBiotic Pharmaceuticals in Cambridge (USA) now have discovered and deciphered the mode of action…
Mice on a time-restricted feeding schedule had better memory and less accumulation of amyloid proteins in the brain compared to controls. One of the hallmarks of Alzheimer’s disease is disruption to the body’s circadian rhythm, the internal biological clock that regulates many of our physiological processes. Nearly 80% of people with Alzheimer’s experience these issues, including difficulty sleeping and worsening cognitive function at night. However, there are no existing treatments for Alzheimer’s that target this aspect of the disease. A…
MHH researcher Prof. Galardini from the RESIST Cluster of Excellence finds causes for bloodstream infections in the genes of bacteria. Escherichia coli bacteria live in the intestines of humans and play an important role there for normal intestinal function as well as for a functioning immune system. These intestinal inhabitants do not form a uniform population, but consist of a large number of strains that differ greatly in their genome and also in their metabolism. Most strains of E. coli…
Using a novel approach of precision neuroimaging and high-resolution functional magnetic resonance imaging (fMRI), neuroscientists and physicists at MPI CBS in Leipzig (Germany) and anatomist Menno Witter from the Kavli Institute for Systems Neuroscience in Trondheim (Norway) have now ventured into the depths of the human memory system. They discovered previously unknown cortical networks and shed light on the anatomical organization of the human memory system. Their findings were recently published in the prestigious journal “Neuron”. How can the amazing…
Researchers identify novel gelatinase substrates involved in astroglial barrier function: In neuroinflammation, immune cells such as leukocytes cross the blood-brain barrier. One key to this is the gelatinases matrix metalloproteinase (MMP)-2 and -9. Until now, the substrates of these enzymes involved in the process were unknown. Now, using a sensitive mass spectrometry-based secretome approach, researchers at the University of Münster and Bonn University Hospital (UKB) have succeeded in identifying hundreds of such molecules that are cleaved from the cell surface…
A new discovery in a cause of inner-ear bone loss. The researchers from Osaka University showed how bone erosion caused by cholesteatoma occurs. This study showed that a subset of cells called osteoclastogenic fibroblasts expresses a protein, activin A, which causes the breakdown of the bones. Because of this discovery, novel medical treatments can be developed as first-line management for cholesteatomas. Researchers from Osaka University show that the possible cause of local bone erosion in cholesteatomas are fibroblasts from the…
Researchers at the RIKEN Center for Sustainable Research Science (CSRS) and the University of Toronto have discovered a new way to attack fungal infections. The key is to block fungi from being able to make fatty acids, the major component of fats. Resistance to anti-fungal drugs is increasing and this new approach will be particularly useful because it works in a new way and affects a broad range of fungal species. The study was published in the scientific journal Cell…
Scientists identified the region where a protein regulates sodium ion channels, inserting the channel’s genetic material into a virus to alleviate pain in cell and animal studies. Researchers at NYU College of Dentistry’s Pain Research Center have developed a gene therapy that treats chronic pain by indirectly regulating a specific sodium ion channel, according to a new study published in the Proceedings of the National Academy of Sciences (PNAS). The innovative therapy, tested in cells and animals, is made possible…
To help bring therapies for rare muscle diseases in children to market sooner, the Berlin-based start-up MyoPax, a spin-off from the Max Delbrück Center and Charité – Universitätsmedizin Berlin, has now received a boost from the U.S. Food and Drug Administration (FDA). The company has been granted the FDA’s orphan drug designation (ODD) and rare pediatric disease designation (RPDD), both of which offer multiple regulatory and financial advantages – including fast-track approval status and, eventually, market exclusivity. But first, the…
A new mRNA vaccine targeting immune cells in the liver could be the key to tackling malaria, a disease that causes over half a million deaths each year according to the World Health Organization, yet has no effective long-lasting vaccine. Trans-Tasman research collaborators from Te Herenga Waka— Victoria University of Wellington’s Ferrier Research Institute and the Malaghan Institute of Medical Research in New Zealand, and the Peter Doherty Institute for Infection and Immunity in Australia have developed an mRNA-based vaccine…
University of Virginia School of Medicine researchers have discovered how the cells that let us hear can repair themselves after being damaged. That important insight could benefit efforts to develop new and better ways to treat and prevent hearing loss. “Hair cells” found in the inner ear, are important both for our ability to hear and our sense of balance. They are known as hair cells because the cells are covered in hair-like structures that serve as mechanical antennas for…
Proof-of-concept device could also monitor for flu, RSV, other respiratory viruses. Now that the emergency phase of the COVID-19 pandemic has ended, scientists are looking at ways to surveil indoor environments in real time for viruses. By combining recent advances in aerosol sampling technology and an ultrasensitive biosensing technique, researchers at Washington University in St. Louis have created a real-time monitor that can detect any of the SARS-CoV-2 virus variants in a room in about 5 minutes. The inexpensive, proof-of-concept…
The strength of the immune reaction triggered by antibodies can be regulated. Antibodies are crucial, not only for treating tumors and infections. Sometimes, however, the immune reaction they trigger can be too strong and end up causing more damage, for example in the case of people infected with Covid-19. Problems such as these can often be avoided by finetuning antibodies, as Prof. Dr. Falk Nimmerjahn from FAU and two of his colleagues in the Netherlands and in the UK have…
