A new infographic produced by the Human Toxicology Project Consortium shows in three sections how the future of toxicity testing promises a steady reduction in testing costs, increases in human relevance and confidence in safety assessments, and the eventual elimination of animal tests.
The first section provides a snapshot comparison of the current and future costs, efficiency and efficacy of toxicity testing, while the mid portion uses pesticide testing as a specific example of now, vs near-future, vs the optimal approach that, given the focus and resources necessary, will be envisioned within the decade.
The near-future and optimal approaches rely increasingly on our understanding of biology and using it to build a predictive systems biology platform that is comprised of an interrelated network of biological pathways. This platform is used to design and interpret tests that provide much more efficient and effective characterization of chemical activity that can be used to predict safe use of chemicals.
Finally, the results of this progression are captured in the summary graphic at the end – decreasing costs, animal use and time while human relevance and our confidence in safety decisions continue to improve.
As explained on our Project page, the Human Toxicology Project Consortium works on three areas critical for the successful, international implementation of a pathways-based approach to chemical safety testing: advancing the science, communicating the purpose and goals of pathway-based toxicology, and lobbying for funding and policy changes that will support pathway-based approaches in the US and around the world.
To advance our communication and education efforts, HTPC member organizations worked together to create this infographic, to quickly and effectively illustrate the differences between traditional animal-based toxicity testing and pathway-based testing in terms of predictive power, cost, and testing capacity.
