Short description:

Our group is interested in molecular pathways that interfere with physiological and pathological processes of neuronal aging.  One of our aims is to elucidate how healthy aging can be achieved, e.g. by using resilience mechanisms. Therefore, we analyse proteins which have been characterized as being longevity factors and/or of neuro-protective property and their potential interplay with gaining resilience. Furthermore, our research is focused on molecular mechanisms of Alzheimer’s disease, one of the major neurological diseases of the elderly.  One example for this is our investigation of the alpha-secretase ADAM10, which is capable to prevent the deposition of senile, neurotoxic plaques in the brain. This enzyme has been shown to increase in cognitively healthy aging but on the contrary to be diminished in MCI (Mild cognitive impairment) or Alzheimer’s disease patients. We identified several regulators of ADAM10 by cellular screening approaches. Some of the “druggable” substances could already be successfully transferred to pre-clinical animal studies and first studies in patients. To pursue these translational trails, we closely interact with medical specialists in dementia and gerontology, the study centre of psychological diseases and behavioural scientists of our clinic as well as with external partners.
