ELDERBERRY AND NEURODEGENERATIVE DISORDERS
May elderberry assist motor recovery and muscle coordination?
Abstract
“Huntington’s disease (HD) is an inherited neurodegenerative disorder which begins in the striatum and then spreads to other neural areas. Knownas a progressive movement cognitive disorder, HD has no efficient therapy. Although the exact mechanism of HD is still unknown, several different etiological processes such as oxidative stress have been shown to play critical roles. Also, the current evidence indicates a strong correlation between immune activation and neural damage induced by neuroinflammatory and apoptotic agents in neurodegenerative disorders. Thus, natural products like Elderberry (EB) could be considered as a novel and potential therapeutic candidate for the treatment of this disease.
In this study EB was added to the daily ration of ordinary rats for two months in order to ameliorate inflammatory and oxidative responses in rats injected with 3-nitropropionic acid (3-NP) in an experimental model of HD. Using Rotarod and electromyography setups, we showed that EB diet significantly recovered motor failure and muscle incoordination in 3-NP injected rats compared to the control group. Also, the molecular findings implied that EB diet led to a significant drop in 3-NP induced growth in caspase-3 and TNF-α concentration. The treatment also improved striatal antioxidative capacity by a significant reduction in ROS and a remarkable rise in GSH, which might be correlated with motor recovery in the tests.
In sum, the findings demonstrate the advantages of EB treatment in the HD rat model with a score of beneficial anti-oxidative and anti-inflammatory effects.”
