RPE65 and retinal degeneration: To further explore the link between CYLD deficiency‐induced retinal degeneration and the phagocytic function of RPE cells, adeno‐associated viruses (AAVs) carrying Cyld shRNAs (shCyld), along with Rpe65 and GFP elements, were generated to achieve RPE‐specific knockdown of CYLD in mice.
