Further, the magnified view of Drosophila eye images from the AD model showed retinal degeneration along with disarrangements of ommatidia and bristles in the eye (Fig. 1c–e) as compared to wild type (OregonR+) and experimental control (GMR-GAL4/+) flies (Fig. 1a,b). The gene discussed is LGALS4; the disease is retinal degeneration.
