BACKGROUND: Parkinson's disease (PD) has emerged as a critical public health challenge amidst global population aging. The pathogenesis of PD is extremely complex. Notably, evidence showed that neuroinflammation due to microglial activation is a critical driver of dopaminergic neuron loss in patients with PD. Therefore, several strategies aimed at alleviating neuroinflammation are currently being tested for the treatment of PD. However, current anti-inflammatory agents exhibit limited therapeutic efficacy in vivo due to hindrances caused by the blood-brain barrier (BBB). To overcome BBB-related challenges, we developed a biomimetic nanodelivery system (DCM@Nar-NCs) by encapsulating naringenin nanocrystals (Nar-NCs) within differentiated HL-60 cell membranes. Our analysis demonstrated that DCM@Nar-NCs could act as an innovative nanoplatform for PD therapy, showing BBB penetration capabilities and exhibiting precise accumulation at sites of neuroinflammation. This targeted delivery enables more precise and potent treatment than existing therapeutic modalities. METHODS: The BBB penetration efficiency and brain-targeted delivery of DCM@Nar-NCs were assessed both in vitro and in vivo. The neuroprotective effects were comprehensively investigated in cellular and animal levels. Finally, the ability of DCM@Nar-NCs to ameliorate motor dysfunction and cognitive impairment was validated in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse models. RESULTS: DCM@Nar-NCs ...
