Using C. elegans to decipher the cellular and molecular mechanisms underlying neurodevelopmental disorders

Area of Science:

• Neurobiology
• Genetics
• Developmental Biology

Background:

• Neurodevelopmental disorders (epilepsy, intellectual disability, ASDs) affect over 2% of the population.
• Genomic techniques have advanced gene identification, but functional validation remains challenging.
• Model systems are crucial for understanding gene function and mutation effects in neurodevelopmental diseases.

Purpose of the Study:

• To review the utility of Caenorhabditis elegans as a model organism for neurodevelopmental disorder research.
• To highlight C. elegans's suitability for studying nervous system function and behavior relevant to these disorders.
• To discuss methodologies and technological advancements for functional gene analysis in C. elegans.

Main Methods:

• Review of C. elegans nervous system architecture and function.
• Analysis of molecular basis for behaviors relevant to neurodevelopmental disorders.
• Examination of methodologies for assessing memory, learning, social behavior, and seizure susceptibility.
• Discussion of microfluidics and optogenetics in C. elegans research.

Main Results:

• C. elegans provides a balance between simplicity and complexity for studying neurodevelopmental disorders.
• Its well-characterized nervous system and observable behaviors are amenable to genetic and functional analysis.
• Technological advances enhance the study of neurobiology and disease mechanisms in C. elegans.

Conclusions:

• Caenorhabditis elegans is an effective model for the functional validation of genes associated with human neurodevelopmental disorders.
• This model facilitates the transition from gene discovery to understanding disease mechanisms and potential therapies.
• The use of C. elegans accelerates research into epilepsy, intellectual disability, and ASDs.
