    Short description

    Our research group investigates the following topics:

    1) Molecular relationships of the physiology and pathology of the neuronal aging process. On the one hand we want to understand how cognitively healthy ageing can be achieved. To this end, we investigate proteins that are characterized as longevity factors or as neuron-protective and their influence by resilience mechanisms.

    2) Molecular mechanisms of Alzheimer's disease. Our focus here is on the alpha-secretase ADAM10, which prevents the formation of senile plaques in the brain. In a translational research approach, we transfer pharmacological substances, which we identify as inducers of alpha-secretase by cellular assays, first into cognitive tests in Alzheimer's model mice and finally into the clinic. We work closely together with the specialists in dementia and ageing research and the Study Centre for Mental Disorders.

    3) Enteric nervous system and the microbiome. The intestine contains the largest peripheral nervous system (ENS) and can therefore serve as a surrogate for processes within the brain. The ENS is strongly influenced by the commensals of the intestine - the microbiome. We are currently investigating how the ENS interacts with the microbiome in the ageing process and in Alzheimer's dementia.
