Iron particles for MR imaging

Physicians, physicists and chemists at Münster University have developed novel iron oxide nanoparticles that can serve as contrast agents for magnetic resonance imaging (MRI). The exceptional aspect: They can be specifically distinguished from naturally occurring iron, thus enabling targeted tracking of immune cells in mice, and providing novel insight into iron metabolism. The study was awarded the title “Paper of the Month” by the Faculty of Medicine.

Targeting systemic inflammation

Although systemic inflammations such as sepsis are not uncommon, there are still major gaps in the understanding of disease progression and the development of treatment options. In order to close some of these gaps, the German Research Foundation is funding a new clinical research group at Münster University with around four million euros over three years.

Immune cells in the spotlight

How do immune cells behave in the body? What happens during immunotherapy? To answer these questions, the European Union brings together leading experts from research and the pharmaceutical industry. 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.

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.
