GDNF (Glial Cell Line-Derived Neurotrophic Factor) is a potent neurotrophic factor critical for dopaminergic neuron survival and peripheral nerve regeneration.
Glial Cell Line-Derived Neurotrophic Factor (GDNF) is a potent neurotrophic factor that was originally discovered for its ability to promote the survival of dopaminergic neurons. It belongs to the GDNF family ligands (GFLs), which includes GDNF, neurturin (NRTN), artemin (ARTN), persephin (PSPN), and neublastin (NRTN-like).
GDNF signals through a unique receptor complex:
This signaling complex activates multiple downstream pathways:
GDNF is expressed in:
GDNF is particularly important for:
GDNF is the most potent neurotrophic factor for dopaminergic neurons:
Clinical trials: Multiple clinical trials have tested GDNF delivery for PD:
Challenges:
GDNF supports:
Therapeutic potential: AAV-GDNF delivery to motor neurons shows promise in preclinical models.
GDNF promotes:
| Approach | Status | Description |
|---|---|---|
| AAV-GDNF gene therapy | Clinical trials | Viral vector delivery to striatum |
| GDNF protein infusion | Discontinued | Initial trials failed; delivery revisited |
| GFRα1 agonists | Preclinical | Small molecule activators |
| Cell therapy | Preclinical | GDNF-secreting cells |
