Outline of Final Research Achievements

We succeeded in creating a permeability model using polar cells. This system proved that retinal pigment epithelium (RPE) cells acquire polar secretion ability of VEGF by having polarity. Next, we examined the mechanism of how drugs currently used clinically permeate RPE. As a prediction, a paracellular / intracellular pathway can be considered, but focusing on endocytosis, in particular via Fc receptor. By administering an endocytosis inhibiting drug, the permeability of the RPE layer of the anti-VEGF drug was suppressed. From this, it was possible to demonstrate the difference in clinical action of anti-VEGF drugs.
