NT-020, a natural therapeutic approach to optimize spatial memory performance and increase neural progenitor cell proliferation and decrease inflammation in the aged rat.
2010
Abstract The process of aging is linked to oxidative stress, microglial activation, and proinflammatory factors, which are known to decrease cell proliferation and limit neuroplasticity. These factors may lead the transition from normal aging to more severe cognitive dysfunction associated with neurodegenerative diseases. We have shown that natural compounds such as polyphenols from blueberry and green tea and amino acids like carnosine are high in antioxidant and antiinflammatory activity that decreases the damaging effects of reactive oxygen species (ROS), in the blood, brain, and other tissues of the body. Furthermore, we have shown that the combination of these nutrients (called NT-020) creates a synergistic effect that promotes the proliferation of stem cells in vitro and in vivo. In the current study, we examined the effects of NT-020 on neurogenesis and performance on a Morris water maze (MWM). Aged (20-month-old) male Fischer 344 rats were treated with 135.0 mg/kg per day (n = 13) of NT-020. Young...
