Abstract:
Huntington's disease ( HD ) is an autosomal dominant disorder, for which clinically available drugs offer only symptomatic relief. These prescription drugs are not free of side effects, and the patients usually suffer from anxiety and depression. We investigated quercetin, a dietary flavonoid with free radical scavenging properties, for its beneficial potential if any, in 3‐nitropropionic acid (3‐ NP )‐induced HD in rats where both drugs were administered simultaneously. Methods Performance of rats on beam balancing, elevated plus maze and gait traits were investigated following 3‐ NP and/or quercetin treatments for 4 days. Striatal biogenic amine levels and monoamine oxidase activity were assayed. Striatal sections were examined for Cd11B and glial fibrillary acidic protein immunoreactivity, and for evidences of neuronal lesion. Results Quercetin significantly attenuated 3‐ NP ‐induced anxiety, motor coordination deficits, and gait despair. While the dopaminergic hyper‐metabolism was unaffected, quercetin provided a significant reduction of 3‐ NP mediated increase in serotonin metabolism. Quercetin failed to affect 3‐ NP ‐induced striatal neuronal lesion, but decreased microglial proliferation, and increased astrocyte numbers in the lesion core. Conclusion These results taken together suggest that quercetin could be of potential use not only for correcting movement disturbances and anxiety in HD , but also for addressing inflammatory damages.
