Research Interests:
Dr. Ingram’s research has focused on nutritional and pharmacological interventions designed to slow the rate of aging and thus reduce the risk of age-related disease and functional decline. The major area of investigation involves in vivo rodent models and in vitro cellular models to identify protective mechanisms invoked by calorie restriction. Long-term calorie restriction has been shown in a wide variety of species to increase lifespan, decrease age-related disease, improve stress responses, and attenuate age-related functional impairments. As a major new research area, his lab is investigating the development of calorie restriction mimetics. The objective is to identify compounds that mimic effects of calorie restriction by targeting metabolic and stress response pathways affected, but without actually restricting caloric intake. Other major lab activities involve developing and conducting behavioral assays of aging in rodents with focus on motor and memory performance. The objective is to identify mechanisms of age-related decline in motor and memory performance. As a primary objective of this research, investigations are directed toward preclinical development of pharmacological, hormonal, genetic, and nutritional interventions that improve behavioral function. To identify age-related structural changes in the brain and alterations produced through various interventions, morphometric analysis using unbiased stereology is applied.
