Abstract
In order to deliver glial cell line-derived neurotrophic factor (GDNF) into the brain, we have established a cell line that produces GDNF in a continuous fashion by genetic engineering. These cells were encapsulated and grafted into parkinsonian model rats that had received unilateral intrastriatal injection of 6-hydroxydopamine 2 weeks earlier. Neurochemical analysis showed that GDNF has been produced from the capsule for 6 months after grafting and histological analysis revealed good survival of GDNF-producing cells in the capsule 6 months after grafting. The density of nigrostriatal dopaminergic fibers in the striatum as well as the number of dopaminergic cell bodies in the substantia nigra recovered significantly after GDNF-producing cell grafting. These results suggest the possible application of GDNF-producing cell grafting for the treatment of Parkinson's disease.
