10 Questions
What is the main function of Interstitial retinoid binding protein (IRBP) in the process of regeneration of bleached photopigment?
It chaperones transretinal from the photoreceptor to the RPE
What is the role of RPE65 in the regeneration of bleached photopigment?
It is involved in the conversion of trans- to 11-cis-retinal in the RPE
What is the function of shedding and renewal of photoreceptor discs?
To continuously remove old discs and replace them with new ones
What is the impact of a separation between the RPE and photoreceptors on photoreceptor health?
It affects photoreceptor health significantly
What is the primary function of the interface between the RPE and photoreceptors?
To enable exchange of nutrients and support photoreceptor health
Which cells become active in the retina when infection is present or injury has occurred?
Microglia
What is the primary function of astrocytes in the retina?
Provide support to nerve fibers and retinal capillaries
Which cells modify the neural signal before it leaves via the optic nerve?
Horizontal cells
What is the direction of information flow in the retina?
Vertical flow from outer to inner retina
What is the target of light in the retina?
Photoreceptors
