A 175-kD mannose-specific receptor has been described in macrophages which appears to mediate pinocytosis and phagocytosis. A mannose-specific receptor has also been found on retinal pigment epithelial cells (RPE). Its role was examined in the phagocytosis of photoreceptor outer segments (ROS) by the RPE. All testing was done on cultured RPE cells(More)
Previous studies have documented the presence of specific lectin-binding domains in the insoluble interphotoreceptor matrix (IPM) isolated from human retina. Peanut agglutinin (PNA) selectively binds to cone matrix domains whereas wheat germ agglutinin (WGA) binds to matrix domains surrounding rods. In the present study, the rod-associated WGA-binding(More)
BACKGROUND Photodynamic therapy (PDT), a therapeutic approach employing a photosensitizer and a specific wavelength of light, is an emerging option for treating neoplastic and nonneoplastic diseases. Keloids are fibroproliferative dermal lesions characterized by the proliferation of fibroblasts. Recently, PDT has been demonstrated as a potential treatment(More)
The apical membranes of retinal pigmented epithelium (RPE) were isolated from adult, normal (LE), and dystrophic (RCS) rats. The proteins of these RPE subfractions were separated through the use of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The lectin-binding properties of glycoproteins were examined in western blots through the use of(More)
