AB-1005 represents a pioneering gene therapy utilizing an adeno-associated viral vector serotype 2 (AAV2) to deliver the human glial cell line-derived neurotrophic factor (GDNF) transgene directly into the brain. This innovative technique allows for precise and sustained expression of GDNF, offering promising therapeutic potential for conditions like Parkinson’s disease characterized by the degeneration of midbrain dopaminergic neurons.
GDNF, a member of the transforming growth factor-β superfamily, has demonstrated remarkable neuroprotective effects in preclinical studies. By promoting the survival and differentiation of dopaminergic neurons in the midbrain, GDNF...
