A high-salt diet is not only bad for one's blood pressure, but also for the immune system. This is the conclusion of a current study under the leadership of the University Hospital Bonn. Mice fed a high-salt diet were found to suffer from much more severe bacterial infections. Human volunteers who consumed an additional six grams of salt per day also showed pronounced immune deficiencies. This amount corresponds to the salt content of two fast food meals. The results are published in the journal "Science Translational Medicine".
An international team of researchers led by the Universities of Bonn and Ulm has investigated how a cell’s own "protein shredder" can be specifically programmed to fight cancer. The researchers were able to demonstrate the degradation of proteins that are overly active in breast cancer, for example. The results are published in the renowned journal "Chemical Science".
Certain forms of epilepsy are accompanied by inflammation of important brain regions. Researchers at the University of Bonn have now identified a mechanism that explains this link. Their results may also pave the way to new therapeutic options in the medium term. They have now been published in the renowned scientific journal "Annals of Neurology".
One of the last arrows in the quiver in the fight against dangerous bacteria is the reserve antibiotic daptomycin. It is used primarily when conventional drugs fail due to resistant bacteria. Although the antibiotic was developed around 30 years ago, its exact mode of action was previously unclear. Scientists at the University of Bonn have now deciphered the puzzle: Daptomycin blocks the integration of important building blocks into the cell wall of the pathogens, thereby killing the bacteria. The results have now been published in the journal "Nature Communications".
A fire alarm went off this morning in Wegelerstraße, Campus Bonn-Poppelsdorf. Next to the University building, which houses, among other things, the University IT, an external cooling unit was on fire.
"Good intentions" do not generally produce "good results". This wisdom also applies to establishing coherent environmental policies. Without proper oversight and planning, environmental policies can lead to unintended and harmful side effects. A current special issue of the journal Environmental Research Letters is devoted to this urgent problem. The guest editors are researchers from the University of Bonn and international partners.
Like a snapshot, amber preserves bygone worlds. An international team of paleontologists from the University of Bonn has now described four new beetle species in fossilized tree resin from Myanmar, which belong to the Kateretidae family. They still exist today, with only a few species. As well as the about 99 million years old insects, the amber also includes pollen. It seems that the beetles helped the flowering plants to victory, because they contributed to their propagation. In turn, the beetles benefited from the new food source. The results have now been published in the journal "iScience".
An immune reaction in the brain seems to play a major role in the development of Alzheimer's disease. In a way, it "adds fuel to the fire" and apparently causes an inflammation that, in a sense, keeps kindling itself. The study has now been published in the journal Cell Reports.
