Fighting viruses with interchangeable defense genes

Bacterial viruses, so-called phages, destroy bacteria. Bacteria are constantly exposed to viral attacks. A research team led by Martin Polz, a microbiologist at the University of Vienna, has now studied how bacteria defend themselves against viral predators. The study shows that bacteria have exchan...

‘Feeling’ the living cell’s life cycle using optical tweezers

Living cells are the basic building blocks of all organisms. We, as humans, are essentially a collection of trillions of living cells: and all these cells emerge from a single fertilized egg. This means that “mitosis” (or cell division) is one of the most fundamental and important processes of life....

Researchers have succeeded for the first time in analyzing nanovesicles and proteins in parallel

To transport substances between cells, they are packaged in nanovesicles. The small vesicles are surrounded by a lipid layer and fuse with the cell membrane at their destination. Within the body, they control many important processes. However, it is still unclear whether the influence in laboratory ...

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 anti...

A Tiny Molecule with a Big Impact

Nitric oxide (NO) occurs naturally in the human body as a messenger substance. It is considered an all-rounder, as it performs numerous important regulatory functions, including immune defense against pathogens. The exact mode of action of this molecule has now been uncovered by immunologist Prof. D...

Scientists discover how bacteria use liquid protein droplets to overcome stress

Scientists have revealed how bacteria make tiny liquid droplets from proteins to help them survive harsh environments and thus reduce their chances of being killed by antibiotics. The study reveals how aggresomes – miniscule liquid droplets assembled from several different proteins – form in respons...

Discovery of a potential new therapy for inflammatory arthritis

In a paper published today in the journal Science Translational Medicine, researchers at the Schroeder Arthritis Institute, part of University Health Network (UHN) in Toronto, have made a discovery that could lead to new treatments for axial spondyloarthritis (SpA), a painful and debilitating form o...

Viral infections could drive neurodegeneration

Some viral diseases could possibly contribute to neurodegeneration. This is reported by researchers of the DZNE in the journal "Nature Communications". Their assessment is based on laboratory experiments in which they were able to show that certain viral molecules promote the intercellular prolifera...

Computer model aims to aid with planning during epidemics

A team of researchers has created a software system designed to model epidemics, with the aim of maximizing public-health protections while minimizing economic and social costs. “The coronavirus pandemic has underscored the need to have a well-designed plan to combat epidemics in a way that balances...
