The 'thermostat' that prevents our brain from overheating
The mechanisms by which the body measures temperature and regulates its own body heat are vital, but still poorly understood. The discovery of the first heat sensor on nerve cells in the skin, for which the U.S. molecular biologist David Julius received this year's Nobel Prize for Medicine, was therefore pioneering. However, a very similar heat sensor, the protein TRPM2, is active not only in the…

How staphylococci protect themselves against antibiotics
The skin bacterium Staphylococcus aureus often develops antibiotic resistance. It can then cause infections that are difficult to treat. Researchers at the University of Bonn have uncovered an ingenious way in which a certain strain of Staphylococcus aureus protects itself against the important antibiotic vancomycin. The results have now been published in the journal Microbiology Spectrum.

New measurements improve diagnosis of ‘woman’s heart’
Researchers at the Catharina Heart and Vascular Center, together with Eindhoven University of Technology, have developed a new measurement method to analyze the smallest capillaries of the heart by measuring blood flow and resistance. The new method to assess coronary microcirculation allows cardiologists to make a clearer diagnosis. Until recently, the tests used for this purpose were not…

Highly potent antibody against SARS-CoV-2 discovered
Scientists at Lausanne University Hospital (CHUV) and École polytechnique fédérale de Lausanne (EPFL) have discovered a highly potent monoclonal antibody that targets the SARS-CoV-2 spike protein and is effective at neutralizing all variants of concern identified to date, including the delta variant. Their findings are published in the journal Cell Reports.

How to break through a tumor's protective shield
The immune system protects the body from cancer. To protect healthy body cells from its own immune system, they have developed a protective shield: the protein CD47 is a so called "don’t eat me" signal, which tells the immune cells to stand back. Tumor cells exploit this CD47-based protection strategy for evading the immune system, by increasing presentation of CD47 on their cell…

Retracing the Covid-19 pandemic in England
The Covid-19 crisis that gripped England between September 2020 and June 2021 can be thought of as a series of overlapping epidemics, rather than a single event, say researchers at the Wellcome Sanger Institute, EMBL's European Bioinformatics Institute (EMBL-EBI) and the German Cancer Research Center.

Stroke: Women remain underrepresented in clinical trials
A new study shows that women are underrepresented in stroke clinical trials relative to the number who have strokes in the general population. The research is published in Neurology, the medical journal of the American Academy of Neurology. “Making sure there are enough women in clinical studies to accurately reflect the proportion of women who have strokes may have implications for future…

Promising approach for pain relief without side effects
Researchers at Lund University in Sweden have developed a completely new stimulation method, using ultra-thin microelectrodes, to combat severe pain. This provides effective and personalised pain relief without the common side effects from pain relief drugs. The study, which was conducted on rats, has been published in the research journal Science Advances.

Is a "natural" Covid-19 infection better than vaccination? It's complicated
Hope for a future without fear of Covid-19 comes down to circulating antibodies and memory B cells. Unlike circulating antibodies, which peak soon after vaccination or infection only to fade a few months later, memory B cells can stick around to prevent severe disease for decades. And they evolve over time, learning to produce successively more potent “memory antibodies” that are better at…

How our lungs 'remember' a Covid-19 infection
After infection with SARS-CoV-2, where does the immune system store the memory to provide long-term protection against reinfection? Though numerous studies have examined blood to track immune responses to SARS-CoV-2, a new study of Covid survivors shows that the memory of the infection is primarily stored in T and B cells within the lung and the lymph nodes surrounding the lung.
