Abstract

Glial cell line-derived neurotrophic factor (GDNF) has been shown to possess potent neurotrophic effects on dopaminergic (DA) neurons. We attempted the transplantation of encapsulated GDNF-producing cells to generate a stable supply of GDNF in the brain to promote neuroprotective and restorative effects for DA neurons. We established baby hamster kidney (BHK) cells and introduced GDNF cDNA to produce human GDNF (BHK-GDNF). These BHK-GDNF cells, or nontransfected BHK cells (BHK-Control), were encapsulated into hollow fibers, and the polymer encapsulated cells were unilaterally implanted into the striatum of adult rats, either before or after the administration of 6-hydroxydopamine into the same striatum. The encapsulated BHK-GDNF cells produced GDNF continuously in the striatum for up to 6 months. The rats that received a BHK-GDNF capsule showed a significant decrease in rotational behaviour compared to those that received a BHK-control capsule. Preservation of the nigrostriatal pathway was significantly greater in those that received a BHK-GDNF capsule than in those that received a BHK-control capsule. This indicates that encapsulated GDNF-producing cells can supply GDNF in a stable fashion and have protective and restorative effects on host DA neurons. Our results support a role for this grafting technique in the treatment of Parkinson's disease.
