Analysis on mechanisms that enable cone photoreceptor cells to work under continuous light conditions.

在脊椎动物的视网膜上，有两种类型的视觉感光细胞，称为视杆细胞和视锥细胞。视杆细胞调节夜间视觉，视锥细胞调节白天视觉。这是众所周知的锥体。视杆细胞调节夜间视觉，视锥细胞调节白天视觉。众所周知，视锥细胞持续接受光刺激的明亮条件。在本研究中，我们发现，在视锥细胞中，(1)磷酸化对视觉色素失活的效率被强烈调节，(2)磷酸化的视觉色素被迅速去磷酸化。这些机制似乎使锥细胞在明亮的条件下产生反应。

In vertebrate retina, there are two types of visual photoreceptor cells, called rods and cones. Rods mediate night vision, and cones mediate daytime vision. It is well known cones. Rods mediate night vision, and cones mediate daytime vision. It is well known bright conditions where cones receive light stimuli continuously. In this study, we found that, in cones,(1) the efficiency of the inactivation of visual pigments by phosphorylation is strongly modulated, and(2) phosphorylated visual pigments are dephosphorylated rapidly. These mechanisms seem to enable cones to generate responses under bright conditions.
