In this study, we successfully constructed a brain-targeted siRNA nanocarrier delivery system for double-gene knockdown. This system can efficiently overcome the obstacle of the BBB, markedly alleviating cognitive and memory deficits in AD mice. It paves the way for novel strategies in the clinical treatment of AD and is expected to bring new breakthroughs and changes to the conquest of this disease.
