New Players in the Immune Response
New Players in the Immune Response
Lymph nodes trigger very different immune responses - depending on which body tissue they are connected to. Special T cells are responsible for this newly discovered relation. The human body contains 600 to 800 lymph nodes, which are specialised organs that trigger immune responses. To be informed about infections in the body, lymph nodes are connected to the individual organs via lymph vessels.

More accurate prediction of cancer risk in Individuals with Li-Fraumeni syndrome
More accurate prediction of cancer risk in Individuals with Li-Fraumeni syndrome
Study from the German Cancer Predisposition Registry: The type of TP53 variant matters Li-Fraumeni syndrome (LFS) is a cancer predisposition syndrome that is caused by pathogenic TP53 variants and is associated with a massively increased cancer risk. It represents one of the most important genetic causes of cancer in children and adults.

When smooth muscle cells lack strength
When smooth muscle cells lack strength
The heart pumps blood through the vascular system, supplying cells with oxygen and energy Smooth muscle cells in the vessels finely regulate the blood flow. If they cannot perform their task, malformations and dilations of the vascular system may occur, according to a research team led by Professor Alfred Nordheim from the Interfaculty Institute of Cell Biology at the University of Tübingen, together with scientists from Tübingen, Münster and Uppsala, Sweden.

’Nutri-Score’ label may counter misleading sugar claims on groceries
Research led by Göttingen University supports the use of Nutri-Score labeling to help boost public health A new analysis suggests that the Nutri-Score-a label indicating the overall nutritional quality of a food product-can counteract the misleading effects of sugar claims. The research was led by the University of Göttingen.

How immune cells overcome exhaustion
How immune cells overcome exhaustion
Subset of T cells crucial for immunotherapy Researchers have discovered a new population of immune cells which are critical in maintaining the immune response against chronic infections and cancer. This population of T cells also mediates the response to immunotherapy using checkpoint inhibitors. The discovery may explain why immunotherapy fails in some people and could lead to the development of more effective new therapies for cancer or severe viral infections.

New Target Structure Against Corona
New Target Structure Against Corona
Completely unexpectedly, the enzyme ceramidase emerges as a new target structure for the therapy of SARS-CoV-2 infections. This is reported by Würzburg researchers in "Cells". Fluoxetine, a common antidepressant, inhibits the SARS-CoV-2 coronavirus in cell cultures and in preparations from human lung tissue.

Many paths are open to neurons born early
Many paths are open to neurons born early
The time of birth of neurons determines what they can become, shows a study by the University of Bonn When it comes to royalty, things are clear: The monarch's first child inherits the crown. Siblings born later must make do with a less glamorous profession. This is quite similar for some nerve cells in the brain.

Antiviral Effect of Plant Extracts
Antiviral Effect of Plant Extracts
Extracts from blueberries and blackcurrants prevent infection by measles and herpes viruses in cell cultures. Würzburg researchers were very surprised by this. For a long time, certain plant extracts and natural substances have been considered to strengthen the immune system or even promote healing in various diseases.

How a harmful fungus renders its host plant defenseless
How a harmful fungus renders its host plant defenseless
Study shows the surgical precision employed by the pathogen in this process The fungus Ustilago maydis attacks corn and can cause significant damage to its host. To do this, it first ensures that the plant offers little resistance to the infection. The surgical precision it applies is shown by a new study from the University of Bonn, which has now been published in the journal New Phytologist.

Leipzig Haematologists Research Rare Forms of Blood Cancer
Although there has been significant progress in the treatment of rare forms of blood cancer in recent years and new drugs have been approved in Germany, the prognosis for many affected individuals remains unfavourable. Research teams at Leipzig University's Faculty of Medicine are working in several preclinical and translational projects to gain a better understanding of these diseases.

Elevator helps bacteria to build an invisibility cloak
Study: Bacterial membrane transporter helps pathogens to hide from immune system The transport of substances across the membrane into the cell is linked to specific membrane transport proteins. Researchers at the University Hospital Bonn (UKB) and the University of Bonn, in collaboration with an international team, have now succeeded in elucidating the molecular structure of a completely new class of such membrane transporters.

Genes influence risk for global cattle disease
Genes influence risk for global cattle disease
Research team discovers tiny mutations responsible for Digital Dermatitis Two tiny mutations in the genome of cattle likely cause some animals to be significantly more susceptible to Digital Dermatitis, an extremely painful disease that is widespread in cattle kept indoors. The two candidate genes were discovered by an international team of researchers from Martin Luther University Halle-Wittenberg (MLU), the University of Göttingen and the University of Wisconsin-Madison in the US.

Similarity between schizophrenia and dementia
Similarity between schizophrenia and dementia
In frontotemporal dementia, the same brain networks can be affected as in schizophrenia Researchers for the first time compared schizophrenia and frontotemporal dementia, disorders that are both located in the frontal and temporal lobe regions of the brain. The idea can be traced back to Emil Kraepelin, who coined the term "dementia praecox" in 1899 to describe the progressive mental and emotional decline of young patients.

Covid-19: New energy for flagging immune cells
Immune cells do not receive sufficient suitable energy carriers in infected individuals, a study reveals In severe Covid-19 patients, the metabolism produces insufficient amounts of certain energy-rich compounds called ketone bodies. However, these energy carriers are needed by two important cell types in the immune system in order to fight the virus effectively.

Viruses help combat antibiotic-resistant bacteria
Cell-free production of bacteriophages More and more bacteria are becoming resistant to antibiotics. Bacteriophages are one alternative in the fight against bacteria: These viruses attack very particular bacteria in a highly specific way. Now a Munich research team has developed a new way to produce bacteriophages efficiently and without risk.

Genetic defect leads to motor disorders in flies
Study by the University of Bonn finds possible links to Parkinson's disease Researchers at the Universities of Bonn and Osnabrück have discovered a protein whose defect causes motor disorders in flies. The protein had also previously been found in human patients with Parkinson's disease. So far, however, it was not known what function it has in the cell.

No better outcome in fungal sepsis by biomarker guided therapy
No better outcome in fungal sepsis by biomarker guided therapy
Because modern medicine enables the treatment of seriously ill and severely immunocompromised patients, severe fungal infections are occurring with increasing frequency in intensive care units. Due to their weakened immune system and the often required broad spectrum antibiotic therapy, sepsis patients in the ICU are at particular risk for invasive infections by Candida, a yeast which is harmless to healthy people.
