Prevention of dopaminergic neuron death by adeno-associated virus vector-mediated GDNF gene transfer in rat mesencephalic cells in vitro.
Glial cell line-derived neurotrophic factor (GDNF) is known as a potent neurotrophic factor for dopaminergic neurons. Since adeno-associated virus (AAV) vector is a suitable vehicle for gene transfer into neurons, rat E14 mesencephalic cells were transduced with an AAV vector expressing GDNF. When compared with mock transduction, a larger number of dopaminergic neurons survived in AAV-GDNF-transduced cultures (234% and 325% of controls at 1 and 2 weeks, respectively; P < 0.01). Furthermore, the dopaminergic neurons in the latter cultures grew more prominent neurites than those in the former. These findings suggest that AAV vector-mediated GDNF gene transfer may prevent dopaminergic neuron death, and is therefore a logical approach for the treatment of Parkinson's disease.
