The recent identification of neurotrophic factors, such as the glial cell line derived neurotrophic factor (GDNF), acting on mesencephalic dopaminergic neurons, offers the possibility to stimulate the axonal regeneration of these cells which are affected in Parkinson's disease. Nevertheless, a safe and efficient GDNF delivery system that may be used in clinical trials is still lacking. We have developed GDNF-releasing microspheres capable of releasing the neurotrophic factor for at least 2 months in vivo. In this study we demonstrate that these microspheres, when implanted in the brains of 'Parkinsonian' rats, were well tolerated, and were able to induce sprouting of the preserved dopaminergic fibers with synaptogenesis. Moreover, this neural regeneration was accompanied by functional improvement. The implantation of GDNF-releasing microspheres could be a promising strategy in the treatment of Parkinson's disease.
