Application of in vitro neurotoxicity testing for regulatory purposes: Symposium III summary and research needs

Neurotoxicology
A K Bal-PriceL G Costa

Abstract

Prediction of neurotoxic effects is a key feature in the toxicological profile of many compounds and therefore is required by regulatory testing schemes. Nowadays neurotoxicity assessment required by the OECD and EC test guidelines is based solely on in vivo testing, evaluating mainly effects on neurobehavior and neuropathology, which is expensive, time consuming and unsuitable for screening large number of chemicals. Additionally, such in vivo tests are not always sensitive enough to predict human neurotoxicity and often do not provide information that facilitates regulatory decision-making processes. Incorporation of alternative tests (in vitro testing, computational modelling, QSARs, grouping, read-across, etc.) in screening strategies would speed up the rate at which compound knowledge and mechanistic data are available and the information obtained could be used in the refinement of future in vivo studies to facilitate predictions of neurotoxicity. On 1st June 2007, the European Commission legislation concerning registration, evaluation and authorisation of chemicals (REACH) has entered into force. REACH addresses one of the key issues for chemicals in Europe, the lack of publicly available safety data sheets. It outlines a...Continue Reading

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Autoimmune Polyendocrine Syndromes

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
