Microtubules control migrating cells

Scientists from the Cluster of Excellence ImmunoSensation and the Institute of Science and Technology Austria published their recent findings about microtubules controling migrating cells in the Journal of Cell Biology. Cells need to navigate throughout the body. How they find their right way and how they adapt their body size to moving into the right direction is poorly understood. Here, scientists demonstrate that spatially distinct microtubule dynamics regulate amoeboid cell migration by locally promoting the retraction of protrusions. Prof. Eva Kiermaier is member of the Cluster of Excellence ImmunoSensation2.


The group of Eva Kiermaier focuses on the contribution of the cytoskeleton during innate and adaptive immune responses. Dendritic cells (DCs) represent the most potent antigen presenting cells of the innate immune system. They are key mediators for the induction of protective immunity as well as maintenance of self-tolerance. As such, DCs represent an outstanding population of cells, which mediate three fundamentally important tasks: antigen capture and presentation, migration and T cell activation. The group studies how cytoskeletal components, in particular centrosomes and microtubules, impact immune cell effector functions such as antigen presentation and migration and their behavior upon lymphocyte cell-cell interactions.

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.”
