Bone research: ISAS participates in the new "DIONE" Collaborative Research Centre

Dortmund, 1st December 2023

What is the connection between our immune system and bone fractures? Why can autoimmune diseases such as rheumatoid arthritis, illnesses such as psoriatic arthritis or chronic inflammatory bowel diseases affect the skeleton? For the first time, scientists will be investigating these questions in the new Collaborative Research Centre (CRC) / Transregio 369 “DIONE”. Researchers at Friedrich-Alexander-Universität (FAU) Erlangen-Nürnberg, Technische Universität Dresden, ISAS and the University of Ulm will be looking into inflammation-induced bone degeneration. The German Research Foundation is funding “DIONE – DegeneratIon of bONE induced by inflammation” for an initial period of four years.

It is known that the immune system reacts to inflammation and releases various mediators such as metabolites. The latter have an effect on bone remodelling by influencing the balance between osteoblasts (bone-building cells) and osteoclasts (bone-degrading cells). However, how exactly the intracellular and extracellular regulatory circuits control inflammation and skeletal reactions has not yet been explored. The scientists at DIONE want to change this by incorporating the latest developments and findings on inflammatory diseases from immunology and bone biology into their research project.

This is why researchers at ISAS and FAU will use various microscopy techniques to investigate whether different osteoclast subpopulations have different activation profiles and functions in addition to their different origins. “We want to find out more about the individual regulatory mechanisms of different osteoclast subtypes during different inflammatory processes and their influence on disease-specific bone damage. We would like to use these new findings to identify potential targets for more specific therapies for various skeletal-associated diseases such as rheumatoid arthritis and osteoporosis,” says Prof Dr Anika Grüneboom from the ISAS Bioimaging research group. Together with Prof Dr Gerhard Krönke (FAU / Charité - Universitätsmedizin Berlin), she is leading the corresponding “DIONE” sub-project.

New “Green” Microscopy: Less Electricity, but More Information on Immune Cells in Return

Advanced technologies, such as high-resolution microscopes, produce large amounts of data. And these again consume large amounts of electricity. In addition, there are refrigerators for samples, fume cupboards and small technical devices. While ISAS is upgrading to become greener, researchers at the institute are already working on methods to make microscopy more energy-efficient in general.

Cirrhosis of the Liver: Migrating Immune Cells Act as an Early Warning System

The life expectancy of patients with liver cirrhosis depends crucially on the occurrence of disease-associated complications, such as infections. Until now, however, an ability to predict these at an early stage has been lacking. A problem, often hindering doctors from administering antibiotics or even performing a liver transplant in time. Researchers at ISAS led by Prof Dr Matthias Gunzer therefore investigated the question: Could the mobility of certain immune cells be the decisive indicator of an impending deterioration in health?

3 Questions for… Dr Christopher Nelke

As a participant in the Clinician Scientist programme and physician at the Clinic for Neurology at Düsseldorf University Hospital (Universitätsklinikum Düsseldorf, UKD), Dr Christopher Nelke researches neuromuscular diseases. In this interview, he talks about his two-week guest stay at ISAS and the challenges that arise between the hospital bed and research.

SARS-CoV-2: The Very Latest Methods Clarify the Active Agents and the Mechanism of Action of Ancient Self-Medications

Prophylactic, soothing or even healing agents, mostly natural substances, have been known to natural medicine since ancient times. But what about viral infections? Could infusions made from sage or perilla also be used against SARS-CoV-2 infections -as a prevention or an aid to healing? An interdisciplinary team of researchers led by Prof Dr Mirko Trilling from the Faculty of Medicine at the University of Duisburg-Essen (UDE) and scientists at ISAS investigated these questions during the coronavirus pandemic.

A Long Sought-After Combination Method in Mass Spectrometry

Researchers who analyse complex samples using mass spectrometers are often faced with the challenge that the substances they contain are fundamentally different. Some are chemically polar, others are non-polar. Until now, this has required two complex separate analyses. But a researcher at ISAS has developed a method with which even less polar substances can be included in a standard mass spectrometric analysis for polar biological substances.

The Art of Balancing: Accuracy in Image Analysis

What challenges in analysing microscopic images can be mastered with artificial intelligence if the latter is incorporated at an early stage? Why should researchers think about the target metrics of image analysis when planning their experiment? Dr Jianxu Chen has now put together his tips, recently published in the journal Nature Methods, as a kind of checklist for researchers.
