Current Topics in Postnatal Behavioral Testing.

Area of Science:

• Toxicology
• Neuroscience
• Risk Assessment

Background:

• Developmental neurotoxicity (DNT) is critical for evaluating therapeutic agents and environmental chemicals.
• DNT involves adverse changes to the nervous system during development, assessed via functional outcomes like behavior and neuropathology.
• Neurobehavioral evaluations are common in animal models, while neurochemistry and neurophysiology are less utilized.

Purpose of the Study:

• To summarize the proceedings of a 2015 symposium on DNT testing.
• To discuss the current status, issues, and recommendations for DNT testing in safety assessment.
• To provide a roadmap for future advancements in DNT evaluation.

Main Methods:

• The article summarizes discussions from the American College of Toxicology annual meeting.
• Key topics included regulatory context, study design, behavioral test selection, and age of testing.
• Considerations for alternative animal models and extrapolation of animal data to humans were also discussed.

Main Results:

• The symposium highlighted the importance of DNT testing in pharmaceutical and chemical safety evaluations.
• Current DNT testing practices and their limitations were reviewed.
• Recommendations for improving DNT study design and interpretation were proposed.

Conclusions:

• Integration of regulatory experience and scientific concepts offers a synopsis of current DNT testing.
• A roadmap for future advancements in DNT testing for safety assessment is outlined.
• Continued research and discussion are vital for refining DNT evaluation strategies.
