A groundbreaking study has unveiled that antioxidants from seaweed can play a pivotal role in preventing Parkinson’s disease. This research, conducted by Osaka Metropolitan University’s Graduate School of Human Life and Ecology under the guidance of Associate Professor Akiko Kojima-Yuasa, delves into the beneficial effects of polyphenols found in Ecklonia cava on neurodegenerative disorders.
Parkinson’s disease, marked by the degeneration of dopamine-producing neurons, significantly impacts motor control and cognitive functions. With the aging global population, the prevalence of this debilitating condition is on the rise.
In this study, researchers used a Parkinson’s disease model in mice, administering Ecklonia cava polyphenols orally for a week prior to exposing the mice to rotenone, a compound known to induce Parkinson’s-like symptoms.
The findings were promising, showing a notable restoration of motor function in the treated mice. Additionally, enhancements were observed in intestinal motor function and the structural integrity of colon mucosa.
Further cellular experiments shed light on the biochemical mechanisms underlying the protective effects of Ecklonia cava. The antioxidants were shown to activate the AMPK enzyme, an intracellular energy regulator, and inhibit the production of reactive oxygen species, which are responsible for neuronal cell death.
“This study suggests that Ecklonia cava antioxidants may mitigate neuronal damage through AMPK activation and reduction of intracellular reactive oxygen species production,” stated Professor Kojima-Yuasa. “We hope that Ecklonia cava will emerge as a potent ingredient in the prevention of Parkinson’s disease.”
