We recently identified, in preclinical studies, specific polyphenol-rich botanical dietary supplements [e.g., grape seed polyphenol extract (GSPE), Concord grape juice (CGJ), and resveratrol (RSV)] that are effective in promoting cognitive and psychological resilience under stress conditions. The overall goal of the proposed Botanical Dietary Supplement Research Center (BDSRC) is to identify the specific polyphenol components from these bioactive botanical supplements that underlie their bioactivities and to characterize specific cellular/molecular mechanisms contributing to the attenuation of physiological stress, such as that associated to stressful life events, that have detrimental impact on psychological health, cognitive functions, and ultimately wellbeing (Projects 1-2). In addition the proposed studies will, for the first time, clarify the role of the gastrointestinal (G) microbiome, particularly the human GI microbiome, in modulating the bioavailability of polyphenol components responsible for the cognitive and psychological health benefits of dietary polyphenol botanical supplements using humanized gnotobiotic mice (Project 3). Thus, the proposed studies, which (1) characterize botanicals, (2) assess, pre-clinically, their bioavailability and bioactivity in the periphery and in the brain, while defining molecular mechanisms of resilience, and (3) identify safety issues essential for future development into clinical application, are in full alignment with the goals of NCCAM and ODS, as indicated in the Research Objectives of the RFA. The proposed studies in this BDSRC will improve scientific knowledge and technical capabilities through the development of a rigorous scientific program, will provide training and career development opportunities, and, critically, will provide an intellectually rigorous examination of the role of dietary polyphenol botanical supplements in the maintenance and promotion of psychological and cognitive resilience.

Public Health Relevance

Promoting psychological and cognitive resilience in response to external stressors is one of the most difficult challenges to brain wellness. The proposed research in this BDSRC will provide a unique and detailed dissection of the role of dietary polyphenolic botanical supplements in the maintenance and promotion of psychological and cognitive resilience in models of social defeat and sleep deprivation.
