The AG Bornhorst deals with the effects of over- and undersupply of trace elements and metals.

The main focus is on the role of environmental and food-relevant metals, especially trace elements (TE), in biological processes. With the help of models such as cells and nematodes (Caenorhabditis elegans (C. elegans)), the effects of over- and undersupply on the organism's health will be better understood.

The investigation of the induction of oxidative stress, neurodegenerative potential, and the genotoxicity and mutagenicity of a compound receives special emphasis. Furthermore, the role of genetic predispositions such as Parkinson's disease is under investigation. It is important to understand how a specific genetic background of a particular disease can influence the TE status or sensitize the organism to TE toxicity.
