Increased light exposure alleviates one form of photoreceptor degeneration marked by elevated calcium in the dark.
BACKGROUND:In one group of gene mutations that cause photoreceptor degeneration in human patients, guanylyl cyclase is overactive in the dark. The ensuing excess opening of cGMP-gated cation channels causes intracellular calcium to rise to toxic levels. The Y99C mutation in guanylate cyclase-activat...
