Photoreceptor-targeted extracellular vesicles-mediated delivery of Cul7 siRNA for retinal degeneration therapy

Photoreceptor loss is a primary pathological feature of retinal degeneration (RD) with limited treatment strategies. RNA interference (RNAi) has emerged as a promising method of gene therapy in regenerative medicine. However, the transfer of RNAi therapeutics to photoreceptors and the deficiency of effective therapeutic targets are still major challenges in the treatment of RD.
