Glial cell line-derived neurotrophic factor (GDNF) is a potent neurotrophic factor that promotes the survival and function of dopaminergic neurons and other neuronal populations. GDNF is critical for maintaining dopaminergic neurons in the substantia nigra and has been extensively studied as a potential therapy for [Parkinson's disease](/diseases/parkinsons-disease).
GDNF is a disulfide-linked homodimeric protein. It belongs to the TGF-β superfamily but shares structural features with other neurotrophic factors:
GDNF binds to the GFRα1 co-receptor, which then activates the RET tyrosine kinase receptor:
| Function | Description |
|----------|-------------|
| Dopaminergic Neuron Survival | Critical for substantia nigra neuron maintenance |
| Motor Neuron Support | Promotes survival of spinal motor neurons |
| Enteric [Neurons](/entities/neurons) | Essential for development and maintenance of ENS |
| Kidney Development | Involved in ureteric bud branching |
GDNF is particularly important for dopaminergic neuron survival in the substantia nigra. Studies show:
GDNF delivery to motor neurons has been explored as a potential therapy:
| Approach | Status | Description |
|----------|--------|-------------|
| GDNF Protein Infusion | Clinical Trials | Direct protein delivery |
| AAV-GDNF Gene Therapy | Clinical Trials | Viral vector delivery |
| Small Molecule Mimetics | Research | Oral small molecules |
| Cell Therapy | Research | GDNF-secreting cells |
GDNF has been extensively studied as a potential treatment for [Parkinson's disease](/diseases/parkinsons-disease) due to its potent effects on dopaminergic neuron survival:
| Approach | Description | Clinical Status |
|----------|-------------|-----------------|
| Intraputaminal Infusion | Direct GDNF infusion into the brain | Mixed results in clinical trials |
| AAV-GDNF | Gene therapy using adeno-associated virus | Ongoing clinical trials |
| Cell-Based Delivery | Transplantation of GDNF-secreting cells | Preclinical |
GDNF protects motor neurons and has been investigated for:
