Sensory Cells (IMAGE) University of Maryland School of Medicine Caption In healthy light-detecting cells (top), the photoreceptor rhodopsin (green) and inversin (red) proteins are contained in separate portions of the cell's antenna-like structures. However, in the light-detecting mouse cells missing complement factor H (bottom left) or with human cells with a high-risk age-related macular degeneration mutation (bottom right), the rhodopsin and inversin proteins overlap (yellow).
