Abstract

Neurodevelopment Individuals with Angelman syndrome experience intellectual disability and seizures throughout their lives. In this condition, ubiquitin-mediated degradation of a key potassium channel is disrupted, allowing for the neuronal excitability and network synchronization that leads to seizure. Sun et al. used brain organoid technology to study what happens in human neurons with a mutation in a ubiquitin ligase that is implicated in Angelman syndrome. In these in vitro models and in a mouse model of Angelman syndrome, antagonists for the potassium channel normalized neuronal excitability. Science , this issue p.
