The central hypothesis driving my research interest is that age-related inflammation in the brain is linked to observed cognitive deficits, specifically spatial learning and memory. My research is conducted with undergraduate students as part of extracurricular research experience in psychology. We have observed that resveratrol (an anti-inflammatory plant compound) protected the middle-aged mouse brain from ethanol-induced damage as measured by a spatial learning and memory task. We found that resveratrol-supplemented diets led to lowered expression of the proinflammatory cytokine IL-6 in the hippocampus, which is key to spatial learning. Additionally, we found that an enriched housing environment also had beneficial effects on the middle-aged mouse’s spatial abilities. The reduced expression of IL-6 was more pronounced in animals which had an early learning experience. This early experience also had a beneficial effect on expression of BDNF, SIRT-1 and TNF-alpha in the hippocampus. I am interested in continuing to examine ways to reduce age-related neuroinflammation and related cognitive declines.
