Parallel visual cycles in the zebrafish retina


Fleisch, V C; Neuhauss, S C F (2010). Parallel visual cycles in the zebrafish retina. Progress in Retinal and Eye Research, 29(6):476-486.

Abstract

Vertebrate vision necessitates continuous recycling of the chromophore 11-cis retinal (RAL). The classical (or canonical) visual cycle employs a number of enzymes located in the photoreceptor outer segment and RPE (retinal pigment epithelium) of the retina to regenerate 11-cis RAL from all-trans RAL. Cone-dominant species are believed to utilize a second, intra-retinal, pathway for 11-cis RAL generation, involving retinal Müller glia cells. This review summarizes the efforts made in zebrafish to gain a better understanding of the role of these two visual cycles for rod and cone photoreceptor chromophore recycling.
