The International Max Planck Research School for Chemical and Molecular Biology (IMPRS-CMB) is a collaboration between the Max Planck Institute of Molecular Physiology and three universities, the Technical University Dortmund (TU Dortmund), the Ruhr University Bochum (RUB) and the University of Duisburg-Essen (DUE).

All four institutes are located in the Ruhr Metropolitan Area of Germany, an extremely vibrant and culturally interconnected region. The same spirit is reflected in the science of our program: research groups, with different and often complementary approaches, combine their efforts to study at the molecular level basic cell physiology.

Below you can find all the research groups that are part of IMPRS-CMB, in alphabetical order. You can also search groups by name, topic or technique.

Research Interest
Aberrant protein folding and neurodegeneration
The main aim of our biochemical research is to identify cellular factors and signaling cascades implicated in neuronal integrity and in the pathophysiological alterations leading to neurodegeneration. Our integrative research has a strong focus on the biochemical and cell biological analysis of cellular pathways, which are also of broad neurobiological interest.
Specifically, we are employing in vitro, yeast, neuronal cell culture and animal models to focus on three major topics:

• Cellular mechanisms underlying the formation and toxic activity of aberrant protein conformers
• Signaling pathways induced by neurotoxic conformers
• Therapeutic strategies for neurodegenerative diseases

Cell culture models, including primary neurons to study formation, spreading and signaling of neurotoxic protein conformers.
In vitro and cell culture models to study import of proteins into the endoplasmic reticulum and mitochondria.
