The German Research Foundation (DFG) is funding a new clinical research unit that will investigate the interaction between the digestive and nervous systems with reference to inflammatory and degenerative diseases, the first collaborative research group in Germany to explore the “gut-brain axis”.

The interdisciplinary team in the unit at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) will receive a total of 6 million euros of funding over the coming four years

For several years now, medical research has become increasingly fascinated by the buzzword “gut-brain axis”. This refers to the assumption that there is a connection between neurological diseases and immunological changes in the gastrointestinal tract, in other words that the gut and the brain interact, and that as a result of this interaction, diseases in either system may mutually affect each other or even act as a trigger for the disease in the first place.

IBD risk

Studies show that patients with chronic inflammatory bowel diseases (IBD) have a greater risk of developing Parkinson’s disease later in life, or that there may be a connection between multiple sclerosis and IBD.

The interaction is controlled by a highly complex communication system involving neural, hormonal, metabolic, immunological and microbial signals. The newly established clinical DFG research unit 5024 “Immune checkpoints of gut-brain communication in inflammatory and neurodegenerative diseases” led by Prof. Dr. Claudia Günther, FAU professor of gastrointestinal pathophysiology, and speaker Prof. Dr. Beate Winner, head of the Department of Stem Cell Biology at Universitätsklinikum Erlangen, will investigate what exactly this communication involves.

The new research field is characterized not only by the close interdisciplinary collaboration between immunology, gastroenterology and neurosciences, but also by the integration of bioinformatics and machine learning as well as medical engineering.

Over the coming years, the researchers hope first of all to obtain more specific insights into the interaction between the gut and the brain in inflammatory and degenerative diseases and to decode immunological switches in communication between the gut and the brain. Building on these findings, they then hope to develop new approaches for treatment aimed at fighting or even preventing diseases of the digestive and nervous systems.
