Detecting the effects of neuroprotection in living cells

Abstract

This paper describes experiments in cell systems that have helped clarify intracellular mechanisms leading to apoptosis. Using the cellular systems described (rat retinal whole mount, rat retinal cell line E1A-NR3, and rat neuronal cell line NG 108-15), it has been possible to demonstrate that intracellular pH change may be the mechanism through which carbonic anhydrases modulate vasodilation and act on retinal blood flow. Intracellular pH can also be used to monitor intracellular changes that precede and occur during apoptosis. The findings also show the potential significance of advanced glycation end products (AGEs) in the glaucomatous process, and the potential for brimonidine and memantine to rescue neuroretinal cells from AGE-induced retinal damage.
