State of the art

Research is looking on the one hand to the protection of animals used for scientific purposes (Directive 2010/63 EU) with the application of 3Rs (Reduce, Refine, Replace), and on  the other hand to a predictive interdisciplinary science both for risks linked to the environment and to human and animal health. The project will be focused on the evaluation of in vitro adverse effects  of Contaminants of Emerging Concern (CECs) (OECD, 2012), natural or synthetic, alone or mixture, using in vitro models through the concept of  Integrated Approaches to Testing and Assessment, IATA.

Aims of the project 

The research activity of the project will be focused on the evaluation of the effects of Contaminants of Emerging Concern, CECs, using in vitro models. Bioavailability, mechanism of action, mode of action, metabolism, transport, and toxicity of some CECs, natural or synthetic, alone or in mixture, will be investigated using alternative methods of Replacement with an integrated testing approach. Predictive 3D in vitro models, in vitro co-cultures and species-specific in vitro barrier (i.e. alveolar, dermal, intestinal), through specific endpoints (cytotoxicity, barrier integrity, marker release), will be useful tools for toxicological studies.  Epithelial cells (i.e. alveolar, intestinal) will be cultured on semi-permeable inserts in order to evaluate absorption profile, and the possible involvement of transporters (i.e. PgP, MDR). In vitro testing strategy, based on the use of complementary cell-based assays for the definition of hepatoxicity, neurotoxicity, Endocrine Disruptors (ED) effects (EATS mechanism),will be also applied with an interdisciplinary collaboration.
