Core Viewpoint - Alzheimer's disease (AD) is characterized by the accumulation of β-amyloid plaques and tau protein tangles, leading to progressive cognitive decline. Current disease-modifying therapies are limited, and chronic neuroinflammation is recognized as a significant component of AD, making the regulation of neuroinflammatory pathways a promising treatment strategy [1][2].
