Edaravone suppresses retinal ganglion cell death in a mouse model of normal tension glaucoma
Glaucoma, one of the leading causes of irreversible blindness, is characterized by progressive degeneration of optic nerves and retinal ganglion cells (RGCs). In the mammalian retina, excitatory amino-acid carrier 1 (EAAC1) is expressed in neural cells, including RGCs. Loss of EAAC1 leads to RGC degeneration without elevated intraocular pressure (IOP) and exhibits glaucomatous pathology includi...
متن کاملRetinal ganglion cell death in experimental glaucoma.
AIMS To determine whether parasol retinal ganglion cells (magnocellular pathway) are selectively lost in the primate model of glaucoma. METHODS Ocular hypertension was induced in one eye of six Macaca fascicularis monkeys for 6-14 weeks. The retinal ganglion cells in these eyes were labelled retrogradely with the tracer horseradish peroxidase (HRP) implanted into the optic nerve and subsequen...
متن کاملRetinal ganglion cell death in glaucoma: mechanisms and neuroprotective strategies.
Various cellular and molecular mechanisms that may lead to apoptotic cell death of retinal ganglion cells in glaucoma are discussed. These cellular mechanisms include neurotrophic factor deprivation, ischemia, glial cell activation, glutamate excitotoxicity, and abnormal immune response. Based on experimental and clinical evidence, the rationale for various neuroprotective strategies is described.
متن کاملRetinal Ganglion Cell Death
1.1 Topographic and cellular organization of the retina The retina is the thin (0.2 mm) lining of the back of the eye that gathers light focused on it by the cornea and lens. The retina has a complex laminar organization; cells are organized into layers (Fig. 1). These layers are named by reference to the middle of the eyeball; the innermost layers are located nearest the vitreous chamber, wher...
متن کاملEffect of geranylgeranylacetone on the protection of retinal ganglion cells in a mouse model of normal tension glaucoma
Glaucoma is characterized by axonal degeneration of retinal ganglion cells (RGCs) and apoptotic death of their cell bodies, and lowering intraocular pressure is associated with an attenuation of progressive optic nerve damage. Nevertheless, intraocular pressure (IOP) reduction alone was not enough to inhibit the progression of disease, which suggests the contribution of other factors to the gla...
