Research focus

Our research group is interested in various aspects of neuroinflammtion and neurodegeneration related to aging.
We are studying in detail the arachidonic acid cascade in microglia with a focus on Prostaglanin E2/D2 and the enzymes involved in their synthesis (COX, mPGES, PGDS).
Another major focus of our group is the role of miRNAs in neuroinflammation, neurodegeneration and peripheral blood cells (monocytes, lymphocytes, thrombocytes).
We also investigate the effects of conventional psychotropic drugs on tachykininergic systems as well as the effects of tachykinin receptor antagonists on monoaminergic neurotransmission and on behaviour in mice.
