Receptor makes mice strong and slim

Study by the University of Bonn identifies molecule that regulates two side effects of aging

Increasing abdominal girth and shrinking muscles are two common side effects of aging. Researchers at the University of Bonn from the Cluster of Excellence ImmunoSensation have discovered a receptor in mice that regulates both effects. Experiments with human cell cultures suggest that the corresponding signaling pathways might also exist in humans. The study, which also involved researchers from Spain, Finland, Belgium, Denmark and the USA, has now been published in the renowned journal "Cell Metabolism".

New test points to precision treatment for autoimmune condition

—Interferon alpha is an inflammatory mediator that can cause Sjögren’s syndrome, an autoimmune disease. This is revealed in a recent study carried out by the University Hospital Bonn together with the University of Bonn, the University of Edinburgh and Newcastle University. Their findings, which have been published in the journal “Lancet Rheumatology,” could make it easier in the medium term to develop drugs to fight this chronic condition.

Making Cancer Cells More Predictable: PRECISE Aims to Forecast Therapeutically Actionable Vulnerabilities

—Which genes and signaling pathways does a cancer cell require to survive? And which of these could serve as therapeutic targets? The pan-European initiative PRECISE aims to identify such vulnerabilities not only through labor-intensive laboratory experiments but also by predicting them using computational models. The UKB and the University of Bonn, represented by Prof. Dr. Maximilian Billmann and Prof. Dr. Jonathan Schmid-Burgk, are among the founding partners of the consortium. The scientific vision of the initiative has now been published in a commentary in Nature Genetics.

Focus on the Guardians of the Antibody Response

—For the immune system to effectively combat pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping to maintain immune tolerance. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have now developed a robust laboratory method that allows Tfr cells to be generated from precursor cells and studied in a targeted manner. The results were recently published in the journal Cellular & Molecular Immunology.
