Microscopes: Looking deep into hidden worlds

Microscopes make it possible to take ever deeper and more precise looks at the smallest of details, and in ever higher resolutions. This article looks at some of the techniques used by researchers at the University of Münster including, among others, high-performance cryogenic electron microscopy available at Prof. Christos Gatsogiannis’ lab, three-photon microscopy used by Prof. Friedemann Kiefer’s group, and insights into confocal laser scanning microscopy provided by Prof. Stefan Luschnig’s group.

Peroxisomal processes: a close-up of biological nanomachines

The cell organelles known as “peroxisomes” dispose toxic substances and fats in the human body, among other things, and, in doing so, they prevent serious illnesses. The “Pex” group of proteins (peroxisomes biogenesis factors) keep these “detox units” functioning properly. Using cryogenic electron microscopy a research team headed by structural biologist Prof. Christos Gatsogiannis have now been the first to show, at the atomic level, how these highly complex processes proceed. The study has been published in the journal Nature Communications.

Podcast marking the World Sepsis Day: Jan Rossaint on systemic inflammation

Sepsis is one of the most dangerous diseases and the third most common cause of death in Germany. Nevertheless, many people are unaware of the symptoms. On the occasion of the World Sepsis Day on 13 September, anesthesiologist and intensive care specialist Prof. Jan Rossaint informs about the disease. He talks about overshooting inflammatory reactions of the immune system, risk factors and health consequences as well as the right treatment and the current state of research. The podcast is available in German.

Secretomics uncovers blood-brain barrier mystery

Researchers at the University of Münster and Bonn University Hospital identify novel gelatinase substrates involved in astroglial barrier function: In neuroinflammation, immune cells such as leukocytes cross the blood-brain barrier. One key to this is the gelatinases matrix metalloproteinase (MMP)-2 and -9. Until now, the substrates of these enzymes involved in the process were unknown. The results have now been published in Science Advances.

New insights into pruning

When an organism develops, non-specific connections between nerve cells degenerate. Researchers at the Cells-in-Motion Cluster of Excellence have now discovered that the spatial organization of a nerve cell influences the degeneration of its cell processes. The study has been published in “Development”.

Migrating cells and their environment

Phd student Sargon Groß-Thebing investigates in a research group at the Cell-in-Motion Cluster of Excellence how the cells’ environment affects their migration.

How do neuronal processes degenerate?

Adults have fewer neuronal connections than infants because during development, neurons degenerate the non-specific connections. Biologist Dr. Svende Hermann investigates a similar mechanism in the fruit fly. In a guest contribution, she explains her research in a way that everyone can understand.

How do cells form blebs for their motility?

In order to be able to move, some cells form protrusions in the form of blebs. How do these blebs form? Researchers at the Cells-in-Motion Cluster of Excellence have discovered that folds in the cell membrane play a decisive role. The study has been published in the journal “Developmental Cell”.

Fish in research

At the Cells-in-Motion Cluster of Excellence there are lots of scientists doing work on and with zebrafish. These fish are perfect for research work because they grow outside the mother’s body and are transparent in the first five days of their life. What the scientists study in the tiny fish embryos is, for example, how bones, blood vessels and lymphatic vessels develop.

Where do stem cells leave marrow vessels?

In stem cell transplantation, new stem cells are transferred to the recipient’s bloodstream and find their own way to the bone marrow. A research team headed by the CiM group leaders Prof. Ralf Adams and Prof. Dietmar Vestweber identified the blood flow conditions under which blood stem cells migrate from the vessels and can seek a niche in the bone marrow.

Stress leads to an internal reorganization of the body’s cells

If cells are under stress, for example in the case of injuries, they react to the stress and reorganize their cytoskeleton. This has been demonstrated by Prof. Roland Wedlich-Söldner and his team at the “Cells in Motion” Cluster of Excellence. Their study has been published in the journal “eLife”.

Fresh wind for old stem cell niches

Researchers at the Max Planck Institute and Münster University have discovered how to increase blood-forming stem cells

Blood vessels play a decisive role in the growth of bone tissue and in blood formation, or haematopoiesis. The blood vessels form so-called vascular niches which ensure that the blood-forming stem cells are preserved. Researchers have now found out how they can enhance the function of vascular stem cell niches in bone marrow and, as a result, increase the number of stem cells.

Using Trojan Horses to Combat Microorganisms

Researchers analyse potential of an approach to treating local infections

Bacterial infections can have serious consequences – for example, when they colonize an artificial heart valve. There is especially problematic when the bacteria are resistant to several antibiotics. Researchers are looking for new methods of treatment as well as for ways to find centres of infection in the body, for example by means of special sugar molecules. Chemists, physicists, biologists and physicians were all involved in the study.

If cells run out of oxygen, they start to shine green

Scientists from Münster developed a new method to indicate acute lack of oxygen in cells

Without oxygen, cells cannot survive. Until now, scientists could not observe the effect that a reduced oxygen supply can have on individual cells. This was technically not feasible before. Scientists from Münster have now developed a reporter, which allows them to see an acute lack of oxygen of cells using light microscopy.

Blood Cells in Action

Biophysicists measure for the first time what happens when red blood cells “wriggle”

For the first time, and using physical methods, scientists from Münster, Paris and Jülich have demonstrated how red blood cells move. There had been real fights between academics over the question of whether these cells are moved by external forces or whether they actively “wriggle”. CiM Junior Research Group Leader Dr. Timo Betz and an international team have now proven that both opinions are correct. The study was published  in “Nature Physics”.
