Summary

Patient-derived cerebral organoids reveal autism spectrum disorder (ASD) pathology, including impaired neuronal differentiation. Drug screening identified IGF1 and Gabapentin as potential therapeutics to correct GABAergic neuron deficits in ASD models.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Genetics

Background:

  • Autism spectrum disorder (ASD) is a complex neurodevelopmental condition impacting social interaction and behavior.
  • Current understanding of ASD pathophysiology is limited by the lack of accurate human models.
  • Animal models have provided insights, but human-specific mechanisms remain elusive.

Purpose of the Study:

  • To replicate pathological phenotypes of idiopathic ASD in human cerebral organoids.
  • To establish a proof-of-concept for developing ASD therapeutics using patient-derived organoids.
  • To identify potential therapeutic compounds for ASD.

Main Methods:

  • In vitro disease modeling using cerebral organoids derived from idiopathic ASD patients.
  • Organoid-based phenotypic drug screening to identify ameliorating compounds.

  • Analysis of neuronal differentiation and GABAergic neuron populations.

    • Main Results:

    • Cerebral organoids from ASD patients showed ventricular zone malformations and impaired early neuronal differentiation.
    • Delayed neuronal differentiation was accelerated in organoids treated with identified compounds.
    • ASD organoids had fewer GABAergic neurons, leading to an excitatory/inhibitory imbalance.
    • IGF1 and Gabapentin rescued GABAergic neuron differentiation defects.

    Conclusions:

    • Patient-derived cerebral organoids serve as a viable model for studying ASD pathophysiology.
    • This approach facilitates the identification of therapeutic targets for ASD.
    • Findings support the development of personalized pharmaceutical treatments for ASD.
