Zunino Lab






Dr. Zunino received a Bachelor's degree in biology and a PhD. in cellular and molecular biology from the University of Nevada, Reno.  She received her postdoctoral training at the Howard Hughes Medical Institute and Department of Pathology at the University of Texas Southwestern Medical Center.  She then held an Assistant Professor position in the Department of Genetics at the University of Erlangen-Nuremberg, Germany where she studied the role of antioxidant phytochemicals as potential chemotherapeutic agents against infant acute lymphoblastic leukemia, which is refractory to conventional chemotherapeutic agents.  Dr. Zunino joined the WesternHumanNutritionResearchCenter in 2003 to continue studies of phytochemicals and their anti-inflammatory and anti-cancer activities.  She also serves as an Adjunct Associate Professor in the Department of Nutrition at the University of California, Davis, and is a member of the American Association of Immunologists, American Association for Cancer Research, and American Society for Nutrition. 


Research Program


The overall objective of Dr. Zunino's research is to understand how phytochemicals from fruits, vegetables, herbs, and spices regulate the immune system. Dr. Zunino has recently completed two human feeding studies to understand how dietary strawberries and grapes can affect lipids and inflammation in obese individuals and lower the risk of obesity-related disease, such as cardiovascular disease. Dr. Zunino has also conducted studies to examine the anti-leukemia and anti-inflammatory activities of phytochemicals and phytochemical-rich foods using mouse models for leukemia and autoimmune disease. Current research is designed to examine the role of fruits in modulating immune function and decreasing the risk for infection in obesity. These studies will aid in defining appropriate dietary intake levels of foods rich in phytochemicals that may contribute to a healthy immune system and reduction of disease in humans.


Research Accomplishments


Discovered that eating strawberries or grapes increased the sensitivity of monocytes from obese humans to bacterial components in a cell culture system.


Found that feeding type 1 diabetic mice food containing 1% grape powder delayed the progression of diabetic inflammation and increased survival of the mice compared to mice receiving regular food. 


Found that one of the metabolites of the phytochemical resveratrol which is found in grapes disrupted mitochondrial function in leukemia cells.
