The role of integrin glycosylation in galectin-8-mediated trabecular meshwork cell adhesion and spreading.

ABSTRACT: Primary open angle glaucoma (POAG) is a major blindness-causing disease, characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork (TM) lining the aqueous outflow pathway modulates the aqueous outflow facility. TM cell adhesion, cell-matrix interactions, and factors that influence Rho signaling in TM cells are thought to play a pivotal role in the regulation of aqueous outflow. In a recent study, we demonstrated that galectin-8 (Gal8) modulates the adhesion and cytoskeletal arrangement of TM cells and that it does so through binding to beta(1) integrins and inducing Rho signaling. The current study is aimed at the characterization of the mechanism by which Gal8 mediates TM cell adhesion and spreading. We demonstrate here that TM
