title: Inhibition of the neuronal insulin receptor. An in vivo model for sporadic Alzheimer disease?
abstract: It has been hypothesized that a central even in the early pathogenesis of sporadic Alzheimer disease (SAD) is the dysfunction of the neuronal insulin receptor signal transduction. To prove this, this receptor was inhibited by a triplicate icv application of STZ. Insulin binding sites were upregulated as in SAD. With respect to glucose transport proteins, detailed investigations are necessary.
