Protective Roles of Grape-derived Polyphenols in Alzheimer’s Disease

National Center for Complimentary and Alternative Medicine (NCCAM). In this consortium, led by the Mount Sinai School of Medicine, NYC (G. Pasinetti, MD, Ph.D., lead CREC PI at Mt. Sinai) with collaborating organizations at Purdue University (M. Ferruzzi, E. Janle, C. Weaver), Nobel Foundation (R. Dixon), Albert Einstein School of Medicine (P. Marambaud ), Texas A&M (S. Talcott) and Rutgers University. At Rutgers, Prof. Simon and Wu, lead this work at Rutgers in which several of our graduate students are heavily involved including: Thomas Villani, Cara Welch (former student) and Adolfo Pertuz. Our role is centered in Core B: The Botanical and Analytical Core, in which our major role is the chemical characterization of bioactive compounds and product standardization for biological studies. More specifically, this has involved the support the individual CERC projects by facilitating the chemical characterization of grape juice/wine

(Project 1); grape seed extract.
(Project 2) to target tissues.
(Project 3) polyphenol fractions and; to determine bioavailability, metabolism and distribution of grape polyphenols including resveratrol.

Rutgers and Purdue are both involved in the characterization, archival and assessment of in vivo polyphenol bioavailability from grape fractions. This work is supported by a grant from the National Institute of Health. National Botanical Center. Center for Excellence in Research on Alzheimers Disease. NIH Award 1 PO1 AT004511-01A.
