Background: Gene therapy is considered one of the most promising approaches to develop an effective treatment for Parkinson's disease (PD). The existence of blood-brain barrier (BBB) significantly limits its development. In this study, lactoferrin (Lf)-modified nanoparticles (NPs) were used as a potential non-viral gene vector due to its brain-targeting and BBB-crossing ability. Methods and results: The neuroprotective effects were examined in a rotenone-induced chronic rat model of PD after treatment with NPs encapsulating human glial cell line-derived neurotrophic factor gene (hGDNF) via a regimen of multiple dosing intravenous administration. The results showed that multiple injections of Lf-modified NPs obtained higher GDNF expression and this gene expression was maintained for a longer time than the one with a single injection. Multiple dosing intravenous administration of Lf-modified NPs could significantly improve locomotor activity, reduce dopaminergic neuronal loss, and enhance monoamine neurotransmitter levels on rotenone-induced PD rats, which indicates its powerful neuroprotective effects. Conclusion: The findings may have implications for long-term non-invasive gene therapy for neurodegenerative diseases in general.
