Abstract:
N-methyl-D-aspartate (NMDA) receptor antagonists mediate adult neurogenic effects. Here, the neurogenic effect of a new NMDA receptor antagonist endowed with neuroprotective effects in Alzheimer's disease mice model. Nine-month-old senescence-accelerated mouse prone 8 (SAMP8) with UB-ALT-EV were orally treated. 5-Bromo-2-deoxyuridine (BrdU) (50 mg/kg) was 3× injected I.P. every 2 h. After 28 days of treatment, SAMP8-treated group improved working memory. Moreover, the number of BrdU+ cells and DCX+ cells in the SAMP8 dentate gyrus (DG) was significantly increased. GFAP+ cells were not affected by treatment. Together, these results provided evidence that UB-ALT-EV promotes the survival and proliferation of neural progenitor cells in the aged SAMP8 hippocampus.
