Cluster Member Bradke publishes in Neuron

Cluster member Prof. Bradke, who works at the German Center for Neurodegenerative Diseases (DZNE) and his group have identified a group of proteins that help to regenerate damaged nerve cells. Their findings are reported in the journal "Neuron".

It is commonly accepted that neurons of the central nervous system shut down their ability to grow when they no longer need it; this occurs normally after they have found their target cells and established synapses. However, recent findings show that old nerve cells have the potential to regrow and to repair damage similar to young neurons. The underlying mechanisms for this rejuvenation have now been uncovered in laboratory studies led by the team of Professor Frank Bradke at the DZNE's Bonn site together with scientists of the University of Bonn.

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.

Larvae of the fruit fly Drosophila (foreground) - have a kind of stretch sensor in the esophagus (grey structure in the middle). It reports swallowing processes to the brain. If food is ingested, special neurons of the enteric nervous system (red) release serotonin.

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.”

Gene scissors switch off with built-in timer

CRISPR gene scissors, as new tools of molecular biology, have their origin in an ancient bacterial immune system. But once a virus attack has been successfully overcome, the cell has to recover. Researchers from the University Hospital Bonn (UKB) and the University of Bonn, in cooperation with researchers from the Institut Pasteur in France, have discovered a timer integrated into the gene scissors that enables the gene scissors to switch themselves off. The results of the study have been published in the renowned journal "Nucleic Acids Research".
