Overview

Preclinical study demonstrates that biomimetic mesoporous manganese nanoparticles reduce neurotoxic plaques and enhance cognition in Alzheimer's mice, suggesting a synergistic therapeutic strategy.

Key Points

To develop a biomimetic mesoporous manganese nanocarrier delivering dual therapeutic peptides across the blood-brain barrier to synergistically treat Alzheimer's disease pathology.
Synthesized mesoporous manganese nanoparticles loaded with an amyloid-beta-inhibiting peptide (LK7) and a tau aggregation-inhibiting peptide (DAA).
Coated the nanoplatform with 4T1 cell membranes (termed MLDC) to facilitate blood-brain barrier penetration and exploit manganese's catalase-mimetic antioxidant capabilities.
Evaluated blood-brain barrier penetration, amyloid-beta aggregation, tau phosphorylation, oxidative stress, and cognitive outcomes in Alzheimer's disease mouse models.
MLDC effectively crossed the blood-brain barrier to concurrently inhibit tau hyperphosphorylation and prevent amyloid-beta aggregation.
Catalase-mimetic activity inherent to the manganese core relieved oxidative stress and reconditioned the pathological microenvironment.
In Alzheimer's disease mice, MLDC reduced amyloid-beta oligomers, phosphorylated tau levels, and neuroinflammation while improving cognitive function and reducing nerve damage.
