chelation by metallothionein (MT) synergistically inhibited Aβ aggregation. Ruthenium (Ru) could real-timely track Aβ degradation and aggregation. The results indicated that PRM-siRNA significantly blocked Aβ aggregation and attenuated Aβ-induced neurotoxicity and apoptosis in vitro by inhibiting ROS-mediated oxidative damage and mitochondrial dysfunction through regulating the Bcl-2 family. PRM-siRNA in vivo effectively improved APP/PS1 mice learning and memory by alleviating neural loss, neurofibrillary tangles and activation of astrocytes and microglial cells in APP/PS1 mice by inhibiting BACE1, oxidative damage and tau phosphorylation. Taken together, our findings validated that BACE1 siRNA-loaded Prussian blue nanocomplexes showed enhanced BBB penetrability and AD synergy therapy.
