Research in our lab investigates the role of oxidative stress in the etiology of neurodegenerative disorders, neurotoxicity, and cognitive decline demonstrated in normal aging. Organelles called mitochondria conduct metabolic processes essential for cell survival, but they also produce the majority of reactive oxygen species that can damage proteins, lipids, and DNA. Mitochondria demonstrate photoreceptive capabilities for particular wavelengths of light including the far-red 670 nm, irradiation of which promotes cell survival in cultured neurons exposed to toxins. Our current research seeks to evaluate the utility of 670 nm photobiomodulation in the treatment of neurodegenerative disorders and neurotoxicity by assessing the effects of irradiation on metabolic processes and oxidative stress in wild-type and neurodegenerative models of Drosophila melanogaster.
