Purpose: Encapsulated cell (EC) biodelivery is a promising, clinically relevant technology platform to safely target the delivery of therapeutic proteins to the central nervous system. The purpose of this study was to evaluate EC biodelivery of the novel neurotrophic factor, Meteorin, to the striatum of rats and to investigate its neuroprotective effects against quinolinic acid (QA)-induced excitotoxicity. Methods: Meteorin-producing ARPE-19 cells were loaded into EC biodelivery devices and implanted into the striatum of rats. Two weeks after implantation, QA was injected into the ipsilateral striatum followed by assessment of neurological performance two and four weeks after QA administration. Results: Implant-delivered Meteorin effectively protected against QA-induced toxicity, as manifested by both near-normal neurological performance and reduction of brain cell death. Morphological analysis of the Meteorin-treated brains showed a markedly reduced striatal lesion size. The EC biodelivery devices produced stable or even increasing levels of Meteorin throughout the study over 6 weeks. Conclusions: Stereotactically implanted EC biodelivery devices releasing Meteorin could offer a feasible strategy in the treatment of neurological diseases with an excitotoxic component such as Huntington's disease. In a broader sense, the EC biodelivery technology is a promising therapeutic protein delivery platform for the treatment of a wide range of diseases of the central nervous system. |
