Research Description
My laboratory is primarily concerned with: (1) the mechanisms of movement of solutes and water across epithelial membranes, (2) the regulation of that movement, and (3) the clinical implications of altering the underlying mechanisms and regulation. Our current focus is on the mechanisms and regulation of aqueous humor inflow into, and exit from, the eye, and their implications for the treatment of glaucoma. Two broad lines of in vitro work are in progress using the techniques of patch clamping, molecular biology, fluorescence microscopy and electronic cell sorting. First, we are seeking to identify the molecular basis for chloride-channel activity, which likely limits the rate of ciliary epithelial secretion. Second, we are also testing our current hypothesis concerning the autocrine and paracrine basis for purinergic regulation of aqueous humor secretion and efflux. We are testing our hypotheses, developed on the basis of our in vitro work, using measurements of intraocular pressure in the mouse.
