Quercetin ameliorates neuroinflammatory and neurodegenerative biomarkers in brain and improves neurobehavioral parameters in repeated intranasal amyloid-beta exposed model of Alzheimer’s disease

Quercetin exerted antioxidant and anti-inflammatory properties to protect brain neuronal health. It also ameliorated Aβ deposition, and regulated APP, BACE-1 and tau hyperphosphorylation in brain, and improved neurobehavioral cognitive parameters.
