A consortium of European research institutes is conducting a systematic literature review on in vitro and alternative developmental neurotoxicity (DNT) methods on behalf of the European Food and Safety Authority. Specifically, the purpose of the review is to determine which test methods or approaches are available to evaluate DNT effects of chemical exposure. To obtain a comprehensive understanding of existing test methods, the consortium has requested submission of information on alternative methods, and is particularly interested in unpublished data that may exist on such methods. Please email responses to or questions about the data request to Jutta Bourgeois at [email protected]. Data is requested by the end of May.
