Once again, the University of Bonn has improved its performance significantly in the QS Rankings by Subject this year, moving further up the leaderboard for Germany in around half of the subjects for which it received a ranking. Leading the field among these subjects is Mathematics, which has come top in Germany and 39th worldwide.

Ludwig van Beethoven’s genome has been sequenced for the first time by an international team of scientists with the participation of the University of Bonn using five genetically matching locks of the well-known composer’s hair. 

Researchers at the Universities of Bonn and Singapore have discovered a new intracellular "smoke detector." The sensor warns of damage to the mitochondria - the microscopic power plants that supply the cell with energy. If it does not function properly, chronic skin diseases can result. The sensor may also be important for unimpaired heart and bowel function. The results have now been published in the journal Nature Immunology.

"Miniature shredders" are at work in each cell, disassembling and recycling cell components that are defective or no longer required. The exact structure of these shredders differs from cell type to cell type, a study by the University of Bonn now shows. For example, cancer cells have a special variant that can supply them particularly effectively with building blocks for their energy metabolism. The results were published online in advance. The final version has now been published in the journal "Molecular & Cellular Proteomics."

The enzyme TBK1 is an important component of the innate immune system that plays a critical role in the defense against viruses. Upon mutation-induced loss of TBK1 function, patients show an increased susceptibility to viral infections. Strikingly, if TBK1 is not expressed at all, this clinical effect is not seen. The mechanism behind this supposed discrepancy has now been elucidated by researchers led by Prof. Martin Schlee from the University Hospital Bonn and the Cluster of Excellence ImmunoSensation2 at the University of Bonn. The study was published in the journal Frontiers in Immunology.

The success of cancer treatment depends not only on the type of tumor, but also on the surrounding tissue. Tumors influence it to their advantage, promoting the growth of blood vessels or fooling incoming immune cells. Developing methods to predict the nature of the resulting tumor microenvironment is the goal of researchers from the Clusters of Excellence ImmunoSensation2 and the Hausdorff Center for Mathematics (HCM) led by Prof. Kevin Thurley at the University of Bonn. The German Federal Ministry of Education and Research (BMBF) is funding the "InterpretTME" project with around 800,000 euros over the next three years.

In epilepsy research, it has long been assumed that a leaky blood-brain barrier is a cause of inflammation in the brain. Using a novel method, researchers from the University of Bonn an the Bonn University Hospital (UKB) have demonstrated that the barrier between the blood and the central nervous system remains largely intact. The approach of their study provides important insights into the development of epilepsy and could significantly optimize drug development in the pharmaceutical industry. The study results have recently been published in the journal Nature Communications.

Viruses use the molecular repertoire of the host cell to replicate. Researchers from the Cluster of Excellence ImmunoSensation2 at the University of Bonn, together with Japanese researchers, want to exploit this for the treatment of influenza. The team led by Prof. Hiroki Kato from the Institute of Cardiovascular Immunology at the University Hospital Bonn has identified a compound that inhibits the body's own methyltransferase MTr1, thereby limiting the replication of influenza viruses. The compound proved effective in lung tissue preparations and mouse studies and showed synergistic effects with already approved influenza drugs. The study is now published in the journal Science.
