Abstract Sight depends on the intimate association between photoreceptors and pigment epithelial cells. The evolutionary origin of this cellular tandem can be traced back to the emergence of bilateral animals, at least 450 million years ago, as they define the minimal unit of the ancestral prototypic eye. Phototransduction is a demanding process from the energetic and homeostatic points of view, and not surprisingly photoreceptive cells are particularly susceptible to damage and degeneration… 
Setting Eyes on the Retinal Pigment Epithelium
TLDR
Present knowledge on RPE morphogenesis is reviewed and potential mechanisms that may explain such transformation using examples taken from embryonic Drosophila tissues that undergo similar shape changes are discussed.
Sfrp1 deficiency makes retinal photoreceptors prone to degeneration
TLDR
It is proposed that Sfrp1 contributes to photoreceptor fitness with a mechanism that involves the maintenance of OLM integrity and is discussed in view of the broader implication of SFRP1 in neurodegeneration and aging.
Stretching of the retinal pigment epithelium contributes to zebrafish optic cup morphogenesis
TLDR
It is shown that, in virtual absence of proliferation, RPE cells stretch into a squamous configuration, thereby matching the curvature of the underlying retina and enabling extreme RPE flattening and accelerated differentiation to enable timely optic cup formation.
CFH exerts anti-oxidant effects on retinal pigment epithelial cells independently from protecting against membrane attack complex
TLDR
Results demonstrated the CFH anti-oxidative stress functions independently of its capacity to inhibit MAC formation and maintained RPE cells tight junctions’ structure and regulated the caspase dependent apoptosis process.
Coordinated Morphogenetic Mechanisms Shape the Vertebrate Eye
TLDR
What advances have taught us about eye morphogenesis is discussed, underscoring possible similarities and differences among vertebrates and how morphogenetic and patterning mechanisms integrate to assemble the final architecture of the eye.
Analysis of gene network bifurcation during optic cup morphogenesis in zebrafish
TLDR
This systematic interrogation of the NR/RPE bifurcation should improve both genetic counselling for eye disorders and hiPSCs-to-RPE differentiation protocols for cell-replacement therapies in degenerative diseases.
Genetics of congenital eye malformations: insights from chick experimental embryology
TLDR
A number of similarities between the chicken and human eye, which might be exploited to address other eye pathologies, including degenerative ocular diseases, are highlighted.
Stretching of the retinal pigment epithelium contributes to zebrafish optic cup morphogenesis
TLDR
It is shown that, in virtual absence of proliferation, RPE cells stretch and flatten, thereby matching the retinal curvature and promoting OV folding, and extreme RPE flattening and accelerated differentiation are efficient solutions adopted by fast-developing species to enable timely optic cup formation.

Eye development: a view from the retina pigmented epithelium
TLDR
Many recent findings are outlined that suggest that a limited number of transcription factors, including Otx2, Mitf and Pax6 and a few signalling cascades, are the elements required for the onset of RPE specification in vertebrates.
The retinal pigment epithelium in health and disease.
TLDR
The magnitude of the demands imposed on this single layer of cells in order to execute these tasks, will become apparent to the reader of this review as will the number of clinical disorders that take origin from these cells.

Directional protein secretion by the retinal pigment epithelium: roles in retinal health and the development of age-related macular degeneration
TLDR
The involvement of directionally secreted RPE proteins in normal functioning of the retina and the potential association of incorrect RPE protein secretion with development of AMD are focused on.
Genetic Reactivation of Cone Photoreceptors Restores Visual Responses in Retinitis Pigmentosa
TLDR
It is shown that expression of archaebacterial halorhodopsin in light-insensitive cones can substitute for the native phototransduction cascade and restore light sensitivity in mouse models of retinitis pigmentosa.

TLDR
The genetic and mechanistic causes of retinal degeneration due to PR cell death — which occurs in conditions such as retinitis pigmentosa and age-related macular degeneration — are being successfully dissected.

TLDR
It is proposed that the retinal ganglion, amacrine and horizontal cells are evolutionary sister cell types that evolved from a common rhabdomeric photoreceptor cell precursor, the proto-eye.

TLDR
The results provide genetic evidence for an essential role of a receptor tyrosine kinase in a specialized form of phagocytosis and suggest a molecular model for ingestion of outer segments by RPE cells.
