EU-ToxRisk


2016 - 2020

The project

The vision of EU-ToxRisk is to drive the required paradigm shift in toxicological testing away from ‘black box’ animal testing towards a toxicological assessment based on a comprehensive mechanistic understanding. EU-ToxRisk will integrate advancements in cell biology, omics technologies, systems biology and computational modelling to define the complex chains of events that link chemical exposure to toxic outcome.

In the framework of this project the TEAM unit:

    • Develops quantitative models describing Adverse Outcome Pathways and QSAR models for the prediction of initiating events that trigger these pathways.

    • Explores and evaluates the possibilities offered by the concept of “biological read-across”

Contributions

TEAM has contributed to the following tasks:

  • qAOPs of renal toxicity,

  • qAOPs mitochondrial toxicity in neural (LHUMES), hepatic (HepG2 and renal (RPTEC) cells,

  • qAOPs of hepatic steatosis,

  • toxicokinetic modelling in zebrafish embryo,

  • QSAR modelling of qAOP related endpoints.
