Animal models of neurodevelopmental disorders with behavioral phenotypes

Area of Science:

• Neuroscience
• Genetics
• Developmental Biology

Background:

• Genetic mutations in animals are crucial for understanding neurodevelopmental disorders.
• Mutant mouse models have limitations due to rodent-human brain differences.
• Nonhuman primates offer a more relevant model for human brain development.

Purpose of the Study:

• To review advances in mouse and nonhuman primate models for neurodevelopmental disorders.
• To highlight the extension of research from mouse to nonhuman primate models.
• To discuss the implications for understanding disease mechanisms and treatments.

Main Methods:

• Review of current literature on mutant animal models.
• Focus on genetic mutation studies in mice and nonhuman primates.
• Examination of gene-edited and cell-based models in primates.

Main Results:

• Mutant mouse models successfully recapitulate neurodevelopmental disorder symptoms.
• Phenotypic reversal in mouse models has not translated to human studies.
• Nonhuman primate models, including MECP2 and SHANK3, are being developed for neurodevelopmental disorders.

Conclusions:

• Mutant mouse models remain valuable but have limitations.
• Nonhuman primate models are increasingly important due to closer physiological similarity to humans.
• Ethical guidelines and infrastructure are developing for primate model dissemination.
