Targeted therapy of Parkinson's disease is an important challenge because of the blood-brain barrier limitation. Here, we propose a natural killer cell membrane biomimetic nanocomplex (named BLIPO-CUR) delivered via the meningeal lymphatic vessel (MLV) route to further the therapeutic efficacy of Parkinson's disease. The membrane incorporation enables BLIPO-CUR to target the damaged neurons, thus improving their therapeutic efficacy through clearing reactive oxygen species, suppressing the aggregation of α-synuclein, and inhibiting the spread of excess α-synuclein species. Compared with the conventional intravenous injection, this MLV administration can enhance the delivered efficiency of curcumin into the brain by ~20 folds. The MLV route administration of BLIPO-CUR enhances the treatment efficacy of Parkinson's disease in mouse models by improving their movement disorders and reversing neuron death. Our findings highlight the great potential of MLV route administration used as targeted delivery of drugs to the brain, holding a great promise for neurodegenerative disease therapy.
