New Study published in Nature Methods

Without fat, nothing works in the body: These substances serve as energy suppliers and important building blocks - including for the envelopes of living cells. Numerous diseases are related to disorders in the fat metabolism, such as obesity or cancer. Prof. Christoph Thiele from the LIMES Institute at the University of Bonn and member of the Cluster of Excellence ImmunoSensation and others are now demonstrating how the fat metabolism can be monitored down to the individual liver cell of a mouse with the greatest sensitivity. This opens up several possibilities, such as minimizing the side effects of new drugs on the fat metabolism. The scientists now present their study in the journal "Nature Methods".

Colored nuclei reveal cellular key genes

—The identification of genes involved in diseases is one of the major challenges of biomedical research. Researchers at the University of Bonn and the University Hospital Bonn (UKB) have developed a method that makes their identification much easier and faster: they light up genome sequences in the cell nucleus. In contrast to complex screenings using established methods, the NIS-Seq method can be used to investigate the genetic determinants of almost any biological process in human cells. The study has now been published in Nature Biotechnology.

Central mechanism of inflammation decoded

—The formation of pores by a particular protein, gasdermin D, plays a key role in inflammatory reactions. During its activation, an inhibitory part is split off. More than 30 of the remaining protein fragments then combine to form large pores in the cell membrane, which allow the release of inflammatory messengers. As methods for studying these processes in living cells have so far been inadequate, the sequence of oligomerization, pore formation and membrane incorporation has remained unclear until now.

Swallowing triggers a feeling of elation

—Researchers at the University of Bonn and the University of Cambridge have identified an important control circuit involved in the eating process. The study has revealed that fly larvae have special sensors, or receptors, in their esophagus that are triggered as soon as the animal swallows something. If the larva has swallowed food, they tell the brain to release serotonin. This messenger substance ensures that the larva continues to eat. The researchers assume that humans also have a very similar control circuit. The results were recently published in the journal “Current Biology.”
