Lifelong vascular growth drives the increase of blood cell production in the skull bone marrow

Researchers working with biochemist Prof Ralf Adams have addressed the fundamental question of whether bone marrow compartments in different bones age in a similar way. The team was able to show that the skull bone marrow is a surprising exception to bone marrow aging and increases blood production throughout life. The study has been published in the journal “Nature”.

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.

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.

The Europe-wide research project "Immune-Image", which is funded with 30 million euros over five years and in which scientists from Münster University are involved, started on 1 October.

New method for the measurement of nano-structured light fields

Physicists and chemists at Münster University have succeeded in developing a technique which is able to detect the typically invisible properties of nano-structured fields in the focus of a lens. This can help to establish nano-structured light landscapes as a tool for material machining, optical tweezers, or high-resolution imaging.

A trigger for motion persistence

Researchers at the Cells-in-Motion Cluster of Excellence have discovered that curvatures of cell membranes trigger a self-organising system. As a result, cells can move in the same direction over a longer distance, forming search patterns. The study has been published in the journal “Nature Physics”.

Signals that guide cells through the body

Cells produce signalling molecules, the Chemokines, which can control the behaviour of other cells. For this purpose they bind to a protein, the chemokine receptor. Each receptor can trigger different responses. Researchers at the Cells-in-Motion Cluster of Excellence have discovered a mechanism behind this.

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.

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.

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.
