Assessment of transport of lipid metabolites within trabecular meshwork cells

Abstract

Lipids from trabecular meshwork (TM) cells are of particular interest to ophthalmological researchers as a therapeutic target for lowering intraocular pressure (IOP) in glaucomatous eyes. Fluorescence-based lipid transport assays (FBLTA) and immunocytochemistry (ICC) are dynamic fluorescence analysis techniques that allow for quantitative and qualitative comparisons, respectively, between multiple samples. Here we describe methods for FBLTA, ICC, and mass spectroscopy designed to measure the kinetics and localization of lipid metabolites within the trabecular meshwork.
