Neurogenic effect of beta-amyloid peptide in the development of neural stem cells.

ABSTRACT: The adult mammalian brain contains neural stem cells (NSCs) with self-renewal and multilineage potential in the hippocampus and subventricular zone. However, neurogenesis from these areas does not compensate for neuronal loss in age-related neurodegenerative disorders such as Alzheimer's disease (AD). To test whether an impairment of neurogenesis could contribute to the pathogenesis of AD, we examined the effects of amyloid-beta peptide (Abeta) on the survival and neuronal differentiation of cultured NSCs from striatum and hippocampus. We show that Abeta peptide does not impair the neurogenic rate in NSC progeny, but that it increases the total number of neurons in vitro in a dose-dependent manner. The neurogenic effect of Abeta peptide is not dependent on soluble factors released from the
