Specific Qualification in TraceAge

The general research area of Julia Bornhorst and her research group focuses on the neurotoxicity of essential trace elements, especially Mn. In order to get insights in the modes of action of Mn-induced neurotoxicity, the Bornhorst group used different in vitro techniques to compare cytotoxic effects, genotoxic effects, bioavailability, the effect on oxidative stress parameters including reactive oxygen and nitrogen species (RONS) induction or ATP amount as well as the impact of Mn on the DNA damage response in different brain cells. Additionally, we applied in vitro blood-brain barrier (BBB) and blood-CSF models to clarify the transfer of Mn into the brain. A recently established in vitro placenta model of human villous trophoblasts will give further insights in the underlying mechanisms of Mn transfer through the placental barrier model. In vivo studies using Caenorhabditis elegans (C. elegans) allowed the Bornhorst group and co-workers to study the interaction of trace elements homeostasis and genetics. Since the worm comprises a complete nervous system consisting of 302 neurons that use an array of neurotransmitters, receptors and signaling mechanisms that are similar to the mammalian brain, the worm has been used for modeling of neurodegeneration. Altogether, the nematode allows a three-way intersection of neurodegeneration, genetics and TE levels as environmental risk factor which will represent key gaps in our understanding of disease etiologies. The expertise of the Bornhorst group comprises the quantification of oxidative stress endpoints and neurotoxicity endpoints in C. elegans in wildtype worms as well as in the background of neurodegenerative disease models.
