Modeling synaptogenesis in schizophrenia and autism using human iPSC derived neurons

Area of Science:

• Neuroscience
• Developmental Biology
• Genetics

Background:

• Schizophrenia (SCZ) and autism spectrum disorder (ASD) are complex neurodevelopmental disorders.
• Genetic and cellular studies implicate glutamatergic synapse dysfunction in both SCZ and ASD.
• Synaptic plasticity makes synapses potential therapeutic targets.

Purpose of the Study:

• To review recent studies on neural cells derived from SCZ and ASD patient induced pluripotent stem cells (iPSCs).
• To highlight the role of glutamatergic synapse formation and function in SCZ and ASD.
• To evaluate the potential of iPSC-derived neurons for studying synaptic dysregulation and developing therapies.

Main Methods:

• Generation of induced pluripotent stem cells (iPSCs) from SCZ and ASD patients.
• Differentiation of iPSCs into neural cells for studying development.
• Analysis of synaptic formation, function, and maintenance in patient-derived neurons.

Main Results:

• Studies using SCZ and ASD patient iPSC-derived neurons support a role for glutamatergic synapse abnormalities.
• iPSC technology enables the study of dynamic synaptic changes relevant to disease.
• Patient-specific iPSC-derived neurons provide a model for investigating synaptic dysregulation.

Conclusions:

• Glutamatergic synapse formation and function are critically involved in both SCZ and ASD.
• iPSC-derived neurons offer a powerful platform for understanding neurodevelopmental disorders.
• This approach facilitates the evaluation and screening of novel therapeutic strategies for SCZ and ASD.
