Chemotherapy or not? Physicists study gene expression tests
Following surgery, patients with breast cancer are faced with the question of whether additional chemotherapy is necessary and really effective. It is important that these women do not receive too much treatment - but not too little treatment either. Physicists from Leipzig University modelled the gene expression tests and examined their usefulness on the basis of these models.

Kidney failure in childhood: Gender influences survival chances
Kidney failure in childhood: Gender influences survival chances
MHH study: Vessels of girls suffer more damage than those of boys Gender plays a role: chronic kidney disease has a greater effect on the vessels of girls than on those of boys. Researchers at the Hannover Medical School (MHH) have now been able to show this in a European study. Although the mortality rate in children after kidney transplantation has fallen in recent decades, it is still very high compared to the general population due to early cardiovascular complications.

How a fungus hijacks our immune system
How a fungus hijacks our immune system
During infection, the yeast Candida albicans stimulates the release of tiny RNA fragments, which then stimulate its own growth. An international research team led by the Leibniz Institute for Natural Product Research and Infection Biology - Hans Knöll Institute (Leibniz-HKI) in Jena has discovered this unusual exploitation of the human immune system.

Genome of Steller’s Sea Cow Decoded
During the Ice Age, giant mammals such as mammoths, sabre-toothed cats and woolly rhinoceroses once roamed Northern Europe and America. The cold oceans of the northern hemisphere were also home to giants like Steller's sea cow, which grew up to eight metres long and weighed up to ten tonnes, and has been extinct for around 250 years.

How our body controls inflammation during clean-up mechanisms of damaged cells
A research team from Cologne and Osnabrück has investigated in detail how messenger substances signal inflammation during the removal of damaged cells in the body. Using high-resolution microscopy methods, the researchers were able to show that two proteins interact dynamically with each other and thus determine whether a dying cell triggers an inflammatory reaction in the body.

'Inflaming' cold tumors
’Inflaming’ cold tumors
Pancreatic carcinoma is a tumor with an extremely poor prognosis for which effective treatments have not yet been found. In a preclinical animal model with mice, a team of researchers has now discovered a way of making pancreatic tumors treatable with immunotherapy methods using a targeted combination of two cancer drugs.

A sponge playing in defence
A sponge playing in defence
Bacteria are extremely resourceful when it comes to adapting to a given environment. A team of researchers from Würzburg has now discovered a new trick bacteria use: a kind of sponge that absorbs certain messengers. Each year, at least 1.27 million people die from an infection with bacteria that are resistant to standard antibiotics, a study recently published in the journal The Lancet reveals.

More is not always better
More is not always better
Proton therapy is a precise and effective treatment for tumours in sensitive areas of the body, such as the brain or the eyes, with the advantage that it spares healthy tissue. In this procedure, protons (positively charged particles) are strongly accelerated and directed with precision into the tumour tissue, which is destroyed in the process.

Cause of inflammatory bowel disease discovered
Cause of inflammatory bowel disease discovered
Chronic inflammatory bowel disease (IBD) is becoming increasingly widespread. Until now, however, the underlying causes of the inflammation responses were unclear. Scientists at the Technical University of Munich (TUM) have now identified a mechanism that triggers a problematic interaction between intestinal bacteria and cells in the intestinal mucus layer in XLP2, a condition associated with IBD.

Covid-19: Three exposures needed for broad immunity
Covid-19: Three exposures needed for broad immunity
Number of exposures to viral spike protein crucial for effective antibody response The immune system develops a high-quality antibody response after three encounters with the coronavirus spike protein. These antibodies are also capable of neutralizing Omicron efficiently. This applies to people who are triple-vaccinated, to those having recovered and then received two vaccinations and to double-vaccinated individuals who have experienced a breakthrough infection.

Immune cells as squatters
Immune cells as squatters
Human immune cells not only circulate in the blood, but can also occupy certain tissues and sometimes remain there for years. A research team led by immunologist Christina Zielinski discovered this phenomenon by examining patient samples after stem cell transplantation. In addition, the researchers were able to characterize the special properties of tissue-resident immune cells in more detail.

National identification promotes compliance with Corona rules
National identification promotes compliance with Corona rules
Nearly every country in the world has been affected by the Covid 19 pandemic. In response, governments around the world have initiated far-reaching measures that have required-and continue to require-profound collective changes in citizen behavior. Especially in the first year of the pandemic, when vaccines were not yet available, it was parti­cularly important that people followed instructions, such as limiting physical contact, refraining from travel, and wearing masks.

Corona-driven Stress in Healthcare Professionals
Stress levels experienced by those working in outpatient care were relatively high during the early phase of the Corona pandemic - higher than in medical personnel working in the two other sectors of the healthcare system, i.e. hospital care and prehospital emergency medicine. This was the conclusion of a study led by Associate Professor Dr Marie Ottilie Frenkel at the Institute of Sports and Sports Sciences of Heidelberg University.

People with hearing prostheses use timbre of voice to recognise emotions
People with hearing prostheses use timbre of voice to recognise emotions
Cochlear implants can help people with hearing loss to perceive acoustic stimuli. Unlike hearing aids, which usually only amplify the volume of sounds, the electronic prostheses directly stimulate the auditory nerve. But can these implants also register "nuances" in communication? After all, when we perceive spoken content, for example when talking to someone, it is often not just a question of what is said, but how it is said.

Unmuting the genome
Unmuting the genome
Hereditary diseases as well as cancers and cardiovascular diseases may be associated with a phenomenon known as genomic imprinting, in which only the maternally or paternally inherited gene is active. An international research team involving scientists at the Technical University of Munich (TUM), the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin and Harvard University in Cambridge (USA) has now investigated the mechanisms responsible for the deactivation of the genes.

Why Sentinel Cells are so Important
Why Sentinel Cells are so Important
The presence of sentinel immune cells is vital to maintain and regulate the balance of the body's immune response. Researchers have discovered an essential role of these cells in the treatment of cancer and severe viral infections. Chronic viral infections and cancers can cause a permanent impairment to the immune system, reducing the ability of immune killer T cells to remove tumour cells, or those infected by a virus - this is referred to as 'immune exhaustion'.
