ABSTRACT
Retinitis pigmentosa (RP) is a severe retinal disease characterized by a progressive degeneration of rod photoreceptors and a secondary loss of cone function. Here, we used CNGB1-deficient (CNGB1(-/-)) mice, a mouse model for autosomal recessive RP, to evaluate the efficacy of adeno-associated virus (AAV) vector-mediated gene therapy for the treatment of RP. The treatment restored normal expression of rod CNG channels and rod-driven light responses in the CNGB1(-/-) retina. This led to a substantial delay of retinal degeneration and long-term preservation of retinal morphology. Finally, treated CNGB1(-/-) mice performed significantly better than untreated mice in a rod-dependent vision-guided behavior test. In summary, this study holds promise for the treatment of rod channelopathy-associated retinitis pigmentosa by AAV-mediated gene replacement.
