The AOP Framework
In regulatory toxicology, an Adverse Outcome Pathway (AOP) is a conceptual construct that portrays existing knowledge concerning the linkage between a direct molecular initiating event and an adverse outcome at a biological level of organisation relevant to risk assessment.
The AOP Framework originates from regulatory toxicology, but molecular initiating events can be triggered by much more than chemicals.
In the CIAO project, we consider the SARS-CoV-2 virus as the stressor.
The AOP Framework is managed by the Organisation for Economic Co-operation and Development (OECD), but the CIAO project is an independent undertaking, making use of the OECD standards.
