In collaboration with scientists at the University of North Carolina at Chapel Hill and the Universidade Federal de Goiás, NICEATM scientists contributed to the development of a model to predict skin sensitization potential of chemicals for two assays, human patch test and murine local lymph node assay, and implemented this model in a web portal (Braga et al. 2017). Work over the last two years focused on substantially revising and expanding the freely available web tool, Pred-Skin version 3.0, to integrate multiple QSAR models developed with in vitro, animal in vivo, and human ex vivo data into a consensus naïve Bayes model that predicts human effects. All models are freely accessible through the Pred-Skin v. 3.0 portal. A publication is being drafted for submission in 2020.
