Cellular Uptake And Actions Of Bilberry Anthocyanins In Retinal Pigment Epithelial Cells, Paul Everett Milbury Jr. Jan 2006

Cellular Uptake And Actions Of Bilberry Anthocyanins In Retinal Pigment Epithelial Cells, Paul Everett Milbury Jr.

Doctoral Dissertations

Inflammation and oxidative stress play a significant role in the pathogenesis of age-related macular degeneration (AMD). In AMD, retinal pigment epithelium (RPE) cells are damaged by oxidative stress and die via the process of apoptosis. Anthocyanins from fruits and berries, such as bilberry (Vaccinium myrtillus), possess significant antioxidant activity in vitro and have been used in "traditional medicine" to treat AMD. It is not clear whether intracellular concentrations of anthocyanins are sufficient to quench radical species and mitigate oxidative stress in vivo. In this research project, human RPE cells in vitro were used to establish an oxidative stress model in …
