Toxicological mechanisms and effects
Utrecht University researchers investigate the cellular and molecular mechanisms of action of toxic substances (food-related products, health products, drugs and environmental contaminants) on the nervous system. Research focuses on adverse effects of toxic substances on neuronal network activity, membrane signaling through membrane receptors and ion channels, and on cellular communication through exocytosis. Additionally, intracellular signaling cascades and neurodevelopment are studied for further hazard characterization of various classes of environmental toxicants.
Projects focus on those exposures that are associated with strong societal concern (e.g., alternative flame retardants, drugs of abuse and electromagnetic fields) and/or neurodegenerative disorders, such as Parkinson's Disease (e.g., pesticides and chemical mixtures) and/or developmental neurological disorders, such as ADHD/ASD (chemical mixtures of pesticides and persistent organic pollutants).
Research Projects
MOMENTUM - Microplastics and Human Health Consortium
The aim of this consortium is to determine the effects of micro- and nanoplastic particles (MNPs) on human health and ultimately to prevent this. The MOMENTUM consortium builds upon the work of 15 breakthrough projects that started in the spring of 2019 within the ZonMw research programme Microplastics & Health.
Duration: 2020 - 2023
Coordinator: Juliette Legler
Project member UU: Roel Vermeulen
Funded by: ZonMw, TNO en Health~HollandNano and Microplastics
Exposure to micro- and nanoplastics (MNPs) is nowadays unavoidable. It is however unclear if there are any adverse effects associated with exposure to MNPs. As the brain is amongst the most sensitive organs of our body, the aim of this project is to determine the potential neurotoxic effects of exposure to (environmentally relevant) micro- and nanoplastics (MNPs).
Coordinator: Remco Westerink
Funded by: ZonMWENDpoiNTs
The European project ENDpoiNTs will develop new testing and screening methods to identify endocrine disrupting chemicals (EDCs) that induce human developmental neurotoxicity (DNT).
Duration: 2019 - 2024
Contact: Remco Westerink
Funded by: European Union’s Horizon 2020 research and innovation programme under grant agreement No. 825759Goliath
GOLIATH focusses on one of the most urgent regulatory needs in the field of endocrine disrupting chemicals, namely the lack of methods for testing EDCs that disrupt metabolism – chemicals collectively referred to as ‘metabolism disrupting chemicals’ (MDCs).

Funded by: European Union’s Horizon 2020 research and innovation programme under grant agreement No 825489RISKHUNT3R
The new Horizon 2020 project RISK-HUNT3R: RISK assessment of chemicals integrating HUman centric Next generation Testing strategies promoting the 3Rs was launched on 1 June 2021. The five-year project aims to develop a novel and modular framework for animal-free next generation risk assessment.
RIVM National Institute for Public Health and the Environment is involved in this European interdisciplinary collaboration, which unites 37 partners, academic researchers, regulators, safety authorities, and safety scientists from key industry sectors.
