Integrins Cooperate to Induce Syndecan-4-Containing Cross-linked Actin Networks in Human Trabecular Meshwork Cells
نویسندگان
چکیده
METHODS. Immunofluorescence microscopy was used to identify molecular components of CLANs and quantitate CLAN formation in HTM cells plated on coverslips coated with various extracellular matrix (ECM) proteins (fibronectin, types I and IV collagen, and vitronectin), vascular cell adhesion molecule (VCAM)-1, or activating antibodies against 1, 3, or 2 1 integrins. These integrin antibodies were also used as soluble ligands.

Beta1 and beta3 integrins cooperate to induce syndecan-4-containing cross-linked actin networks in human trabecular meshwork cells.
PURPOSE To characterize the molecular composition of cross-linked actin networks (CLANs) and the regulation of their formation by integrins in normal human trabecular meshwork (TM) cells. CLANs have been observed in steroid-treated and glaucomatous TM cells and have been suggested to contribute to decreased outflow facility by altering the contractility of the TM. METHODS Immunofluorescence m...

PURPOSE To determine the effects of glucocorticoid treatment on the microfilament structure of cultured human trabecular meshwork cells. Topical or systemic administration of glucocorticoids can lead to the development of ocular hypertension and to the development of vision loss, which is clinically similar to primary open angle glaucoma. However, the mechanism(s) by which glucocorticoids cause...

PURPOSE To examine the adhesion of human trabecular meshwork cells with various extracellular matrix (ECM) proteins and to evaluate the roles and distribution of integrin receptors. METHODS Cultured human trabecular meshwork cells were added to 96-well plates either uncoated or coated with proteins including fibronectin, laminin, and vitronectin, as well as collagen types I, III, IV, V, and V...
متن کاملEffect of CLC-2 on the cytoskeleton in human trabecular meshwork cells.
The chloride channel protein 2 (CLC‑2) is important in maintaining the volume of trabecular meshwork cells by adjusting the outflow of aqueous solutions and maintaining the fluid balance. However, little is known concerning the functions of CLC‑2 in the cytoskeleton, specifically in human trabecular meshwork (HTM) cells. In the present study, two CLC-2 specific siRNAs (siRNA1 and siRNA2) that t...
