Erythrocyte phagocytosis in the human trabecular meshwork.
The mechanisms of erythrocyte disposal by the trabecular meshwork in the human eye have not been extensively studied by electron microscopy. At the present time there is one short report on the ultrastructural changes induced by post-traumatic recurrent hyphaemas in two elderly patients. In both patients, Yamashita and Rosen ( I965) observed infiltration of the endothelial meshwork by phagocyti...
متن کاملHyaluronan in the human trabecular meshwork.
PURPOSE Hyaluronan (HA) is a high-molecular weight glycosaminoglycan that can affect water and solute fluxes in the extracellular matrix. The distribution of HA in the human trabecular meshwork of nonglaucomatous eyes was examined to help understand the potential role of HA in the regulation of aqueous outflow resistance. METHODS Histolocalization of HA was established in situ in the trabecul...
متن کاملsCD44 internalization in human trabecular meshwork cells.
PURPOSE To determine whether soluble CD44 (sCD44), a likely biomarker of primary open-angle glaucoma (POAG), is internalized in cultured human trabecular meshwork (TM) cells and trafficked to mitochondria. METHODS In vitro, 32-kD sCD44 was isolated from human sera, biotinylated, and dephosphorylated. TM cells were incubated for 1 hour at 4°C with biotinylated albumin (b-albumin), biotin-label...
متن کاملMicrofilaments in the cells of the human trabecular meshwork.
In this present study the results are presented of a combined ultrastructural and immunofluorescent investigation of 'smooth muscle' elements within the cytoplasm of human trabecular meshwork cells. The cytoplasm of human meshwork cells both in vivo and in vitro is replete with 10 nm intermediate filaments and also contains smaller 6 nm filaments which are particularly prominent in the cell pro...
متن کاملHuman trabecular meshwork cell volume regulation.
The volume of certain subpopulations of trabecular meshwork (TM) cells may modify outflow resistance of aqueous humor, thereby altering intraocular pressure. This study examines the contribution that Na+/H+, Cl-/HCO exchange, and K+-Cl- efflux mechanisms have on the volume of TM cells. Volume, Cl- currents, and intracellular Ca2+ activity of cultured human TM cells were studied with calcein flu...
