The interleukin-8 luciferase (IL-8 Luc) assay is an in vitro method for detecting IL-8 promotor activity, for which an increase is directly linked to Key Event 3 (KE3) in the OECD’s Adverse Outcome Pathway (AOP) for skin sensitisation. The OECD has recently validated the assay, concluding that it is well defined, with a clear protocol and criteria for data evaluation, and with some advantages (over existing KE3 methods) in terms of technical performance and time requirements. As such, it was concluded that the IL-8 Luc assay should be adopted as part of the Integrated Testing Strategy for skin sensitisation.
