Suitability of 3D human brain spheroid models to distinguish toxic effects of gold and poly-lactic acid nanoparticles to assess biocompatibility for brain drug delivery

open access: yesParticle and Fibre Toxicology, 2019
Background The blood brain barrier (BBB) is the bottleneck of brain-targeted drug development. Due to their physico-chemical properties, nanoparticles (NP) can cross the BBB and accumulate in different areas of the central nervous system (CNS), thus are ...

Deconvoluting gene and environment interactions to develop an “epigenetic score meter” of disease

open access: yesEMBO Molecular Medicine, 2023
Human health is determined both by genetics (G) and environment (E). This is clearly illustrated in groups of individuals who are exposed to the same environmental factor showing differential responses.

The 19th FRAME Annual Lecture, November 2022: Safer Chemicals and Sustainable Innovation Will Be Achieved by Regulatory Use of Modern Safety Science, Not by More Animal Testing

open access: yesAlternatives to laboratory animals : ATLA, 2023
The decisions we make on chemical safety, for consumers, workers and the environment, must be based on the best scientific data and knowledge available. Rapid advances in biology, in cell-based technologies and assays, and in analytical and computational

Artificial intelligence as the new frontier in chemical risk assessment

open access: yesFrontiers in Artificial Intelligence, 2023
The rapid progress of AI impacts various areas of life, including toxicology, and promises a major role for AI in future risk assessments. Toxicology has shifted from a purely empirical science focused on observing chemical exposure outcomes to a data ...

Upholding the EU's Commitment to ‘Animal Testing as a Last Resort' Under REACH Requires a Paradigm Shift in How We Assess Chemical Safety to Close the Gap Between Regulatory Testing and Modern Safety Science

open access: yesAlternatives to laboratory animals : ATLA, 2021
Animal use for testing chemicals under REACH continues to increase, despite advances in non-animal safety science during the past 15 years. The application of modern science and technology, and the use of ‘next generation’ weight-of-evidence assessment ...

Organotypic Models to Study Human Glioblastoma: Studying the Beast in Its Ecosystem

open access: yesiScience, 2020
Summary: Glioblastoma is a very aggressive primary brain tumor in adults, with very low survival rates and no curative treatments. The high failure rate of drug development for this cancer is linked to the high-cost, time-consuming, and inefficient ...

A History of Regulatory Animal Testing: What Can We Learn?

open access: yesAlternatives to laboratory animals : ATLA, 2022
The contemporary pharmaceutical industry is voicing growing concerns about the translatability and reproducibility of animal models. In addition, the usefulness of certain of the required regulatory safety tests in animals is being increasingly ...

Microglia Increase Inflammatory Responses in iPSC-Derived Human BrainSpheres

open access: yesFrontiers in Microbiology, 2018
Human induced pluripotent stem cells (iPSCs), together with 21st century cell culture methods, have the potential to better model human physiology with applications in toxicology, disease modeling, and the study of host-pathogen interactions.

Recent Developments in Alternatives to Animal Testing

open access: yesAnimal Experimentation: Working Towards a Paradigm Change, 2019
At least 115 million animals are thought to be used for scientific purposes every year, worldwide (Taylor et al., 2008). Animals are typically used to test whether an intervention will cause harm to humans or other animals of the same or different ...
