PURPOSE Mutations in many rod genes can cause inherited blinding neurodegeneration in the retina characterized by sequential death of rod and cone photoreceptors. This study was to examine the morphological changes of the cone photoreceptors in retinal degeneration (rd1) mice caused by rod-specific cGMP phosphodiesterase beta-subunit gene mutation and to(More)
The goal of this study was to determine whether the jellyfish green fluorescent protein (GFP) could be used in transgenic mice to label and purify cone photoreceptors from the living retina. We created a transgene containing the 5' regulatory sequence of the human red pigment gene (pR6.5 lacZ clone; kindly provided by J. Nathans & Y. Wang), fused to the GFP(More)
Interphotoreceptor retinoid binding protein (IRBP) is a retinoid and fatty acid binding glycoprotein secreted by rod and cone photoreceptors in all vertebrates. IRBP is believed to serve as a carrier for retinoids in the bleaching and regeneration cycle of rhodopsin. IRBP protein has been found to be decreased in vitamin A-deprived rats; it is rapidly(More)
PURPOSE Normal function of the retina relies on the orderly stereotyped organization of different neurons and their synaptic connections. How such neural organization is patterned during development remains poorly understood due to the paucity of adequate developmental markers. This study was to examine the spatial organization and development of cone(More)
