| Outline of Final Research Achievements |
In this study, with the aim of clarifying the mechanism by which xanthophyll is incorporated into the retina and the role played by retinal function, we investigated the uptake into the cell, its pathway, and the effect on cell migration by using retinal pigment epithelial cells and retinal glial cells which constitute the retina. It was revealed that lutein is taken up into cells in concentration and time dependence. Inhibition of the known lutein transport pathway did not cause a significant change in lutein uptake. Also, lutein had no significant effect on cell migration. It is important to investigate the metabolism of intracellular lutein and the role of lutein further in the near future.
