Objective:

The goal of this project is to develop models for integrating organotypic culture responses to Engineered Nanomaterials (ENMs) across the lung, liver, kidney and testis and to predict whole organism response. We will use a systems-based Adverse Outcomes Pathway (AOP) approach linked with toxicokinetic and dynamic models to identify key molecular initiating events and cellular, tissue and organ responses from each organotypic model. These AOPs will then be integrated with lifestage and genetic susceptibility factors to model ENM toxicity response across organ systems, organisms and populations. This project will also identify critical data gaps and make recommendations for further testing of ENMs.

Approach:

Design of custom applications for extraction of microphysiometer output data into PBTK models.
