An iPSC-derived blood-brain barrier to model neurodegeneration

01:0541 days ago

The blood-brain barrier is a layer of cells that protects our brain from harmful compounds. However, due to this tight barrier, many drugs to treat neurological diseases cannot enter the brain either.
There are currently no good models to test these types of drugs. Henrique Nogueira Pinto is a PhD candidate at the Vrije Universiteit in Amsterdam. He is developing a blood-brain barrier model coupled to mini-brains. With this model, he aims to more reliably test how drugs can be transported over the blood-brain barrier and what their effect on the brain is.

Thyroid Hormone & Brain Development: animal-free models for human safety assessment

The environment can have a significant impact on a child's health even before birth. Brain development begins in the first trimester and continues until the age of 25, with thyroid hormone playing a critical role. During early pregnancy, the fetus depends on the mother's thyroid hormone, and a disruption in the thyroid hormone balance can lead to cognitive and motor impairments in the child. As part of the VHP4Safety project, we are developing in vitro tests to measure the developmental neurotoxic effects caused by disturbances thyroid hormone concentrations. Current testing guidelines do not always include testing for neurodevelopmental effects, highlighting the need for new non-animal methods. At the Erasmus Medical Center, human cell lines representing brain cell types are cultured to study the effect of chemicals on the thyroid hormone balance. RIVM uses human stem cells to create neuron-astrocyte networks that mimic brain development. By combining these different assays and models, we are creating a comprehensive human-based testing strategy to assess developmental neurotoxicity. These advances are a critical step toward eliminating animal testing while protecting the health and environment of future generations.
