Neuropeptide S facilitates spatial memory and mitigates spatial memory impairment induced by N-methyl-D-aspartate receptor antagonist in mice.

abstract：:Recent evidence has suggested that down-regulation of somatostatin (SST) expression in the human brain during early stages of aging leads to an elevation in the steady-state levels of Abeta and therefore may be involved in Alzheimer's disease (AD) progression. We hypothesized that alterations in the SST gene might alt...
