Survivin enhances hippocampal neurogenesis and cognitive function in Alzheimer's disease mouse model.

ABSTRACT:

Aims

Cognitive impairment is associated with reduced hippocampal neurogenesis; however, the causes of decreased hippocampal neurogenesis remain highly controversial. Here, we investigated the role of survivin in the modulation of hippocampal neurogenesis in AD.

Methods

To investigate the effect of survivin on neurogenesis in neural stem cells (NSCs), we treated mouse embryonic NSCs with a survivin inhibitor (YM155) and adeno-associated viral survivin (AAV-Survivin). To explore the potential role of survivin expression in AD, AAV9-Survivin or AAV9-GFP were injected into the dentate gyrus (DG) of hippocampus of 7-month-old wild-type and 5XFAD mice. Cognitive function was measured by the Y maze and Morris water maze. Neurogenesis was investigated by BrdU staining, immature, and
