Stargazin mutation impairs cerebellar synaptogenesis, synaptic maturation and synaptic protein distribution.

Abstract excerpt

Stargazin mutation results in absence epilepsy and cerebellar ataxia in stargazer (stg) mice. We have previously discovered defects of AMPA receptor function, failure of BDNF expression and immature morphology specifically in the cerebellar cortex of stg mice. To further characterize the nature of synaptic abnormalities, we examined the ultrastructure of cerebellar granule cell output synapses and measured the...
