Class: Event
An Event is a measurable biological change at a defined level of biological organization, described in the abstract so that it can be measured and supported by evidence. An Event may be described in the AOP-Wiki before it is used anywhere, and becomes a Key Event when it is incorporated into an Adverse Outcome Pathway. The AOP-Wiki defines a Key Event as "a change in biological or physiological state that is both measurable and essential to the progression of a defined biological perturbation leading to a specific adverse outcome." Within a pathway, the Key Events at the starting and ending positions are Molecular Initiating Events and Adverse Outcomes, and those between them are intermediate Key Events. These positions are recorded per pathway and rest on the mechanistic evidence available to the authors of that pathway, so one Event may serve as a Molecular Initiating Event in one Adverse Outcome Pathway and as an intermediate Key Event in another.
__
Whether an Event's change can be measured experimentally depends on factors such as the level of biological organization and the species. Molecular and cellular changes can be tested and measured in model organisms in a laboratory context. Changes up to the population level can be observed in model organisms in a lab and in ecological indicator species. Changes at the individual or population level in humans are observed through epidemiological and clinical studies rather than tested.
__
An Event is a type of change rather than a particular occurrence of one, and is therefore not an exposure event in an open system: the exposure of a population to a pollutant in air or water is not an Event. Such real-world exposures can rarely be observed at the molecular level, so the Molecular Initiating Event that follows one is not usually observable at the time of the exposure event. Describing Events in the abstract keeps supporting evidence separate from what is inferred.
