Neurotrophic factors trials | Target neurons | Animal models | Clinical |
---|---|---|---|
BDNF, GDNF, CNTF | Motor neurons | ALS | BDNF |
NGF, BDNF, FGF2 | Basal forebrain Cholinergic, hippocampal and cortical neurons | AD | NGF, BDNF |
BDNF, GDNF/Neurturin, FGF2 | Dopaminergic neurons | PD | GDNF, BDNF |
BDNF, NT-4, FGF2 | Striatal neurons | Huntington’s disease | |
BDNF, NT-3, FGFs | Descending motor pathways | spinal cord injury | |
BDNF, FGFs, PDGF | striatal, nigral, cortical, | HAND |
The activity of neurotrophic factors described here refers to prevention of cell death in vivo. Clinical trials of BDNF in ALS have shown modest or no effect. References are given in text.
