| Caption | A, light microscopy and immunohistochemical staining of rhodopsin in the central retina from RhoTvrm4/Rho+ mutant mice with 1- or 5-min exposures to bright light. Histological changes in the retinas of RhoTvrm4/Rho+ mutants are observed within 1 hour (top) following exposure to bright light. At 24 hours (middle) following the exposure to bright light, the outer and inner segments of the RhoTvrm4/Rho+ mutant photoreceptors are disorganized. At 1 week (bottom) following exposure, the outer nuclear layer is reduced to two rows of cell bodies. B, rhodopsin (red), ezrin (yellow), and 4', 6-diamidino-2-phenylindole (blue) staining of the retinas from wild-type and RhoTvrm4/Rho+ mutant animals 1 or 24 hours after exposure to bright light. Photoreceptor outer segments are engulfed within the RPE cells of mutant eyes at 1 hour after exposure to bright light, n = 2 animals. C, photoreceptors of Rho mutants are apoptotic 24 hours following exposure to bright light. Terminal uridine deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining of the retina was 24 hours following bright light exposure, n = 3 animals. D, the Tvrm1 mutation (in RhoTvrm1/Rho+ mice) makes the retina more vulnerable to light damage than the Tvrm4 mutation (in RhoTvrm4/Rho+ mice). Light microscopy of the central retina at different times following different durations of exposure to bright light. Red arrows indicate chromatin aggregates and blue arrows indicate macrophages, n = 3 mice for all groups except for RhoTvrm1/Rho+ where n = 6. | ||||||
