Significats de visual pigment en anglès

Molecular evidence suggests that each retina expresses a different visual pigment.

A new high-resolution structure is reported for bovine rhodopsin, the visual pigment in rod photoreceptor cells.

Goldfish has a UV-sensitive visual pigment (S group) localized in miniature single cone cells.

Activation of the visual pigment by light in rod and cone photoreceptors initiates our visual perception.

The visual cycle is a chain of biochemical reactions that regenerate visual pigment following exposure to light.

The retinoid profile is altered as judged by biochemical analysis, arguing for a partial block in visual pigment regeneration.

Activation of the visual pigment by light triggers a transduction cascade that produces experimentally measurable electrical responses in photoreceptors.

Rhodopsin has been intensively characterized in its role as a visual pigment and G protein-coupled receptor responsible for dim-light vision.

The 9-methyl group of 11-cis-retinal plays a crucial role in photoexcitation of the visual pigment rhodopsin.

These data support the premise that rods and cones have mechanisms for handling retinoids and regenerating visual pigment that are specific to photoreceptor type.

Both RPE65 isomerase of the visual cycle and the rhodopsin visual pigment have recently been identified as critical players in mediating light-induced retinal degeneration.

We report experiments designed to test the hypothesis that the aqueous solubility of 11-cis-retinoids plays a significant role in the rate of visual pigment regeneration.

Frogs have a violet-sensitive visual pigment (S group) in small single cone cells and a blue-sensitive visual pigment (MS group) in green rod cells.

The retinal pigmented epithelium (RPE) forms the outer blood-retinal barrier and provides nutrients and recycling of visual pigment to the photoreceptors, among many other functions.

Vision relies on photoactivation of visual pigments in rod and cone photoreceptor cells of the retina.

For example, rod and cone visual pigments couple to distinct variants of the heterotrimeric G protein transducin.
