Filed:

Mar 12, 2009

Appl. No.:

12/402833

Inventors:

Steven L Bernstein - Chevy Chase MD, US

Assignee:

University of Maryland, Baltimore - Baltimore MD

International Classification:

A61K 31/5575

US Classification:

514573

Abstract:

The present invention provides a method for treating or reducing damage to the optic nerve in a subject comprising administering to the subject a therapeutically effective amount of prostaglandin J2 alone or in combination with an effective amount of GM-CSF. In particular aspects of the invention, the subject is a mammal, and in further aspects the mammal is a human.

US Classification:

800/003000, 424/009200

Abstract:

Anterior ischemic optic neuropathy (AION) is one of a family of ischemic diseases affecting the optic nerve. A blockage of vessels supplying the intra-retinal portion of the optic nerve results in loss of axon transport stasis, retinal ganglion cell (RGC)—specific dysfunction, and RGC death. AION research has been limited by the lack of a low-cost model for this disease. The invention of such a model has now been developed. Using a custom contact lens, an intravenous injection of photosensitizing agent is administered to anesthetize male Sprague-Dawley rats. A laser was used to activate dye within the small vessels perfusing the optic nerve. This treatment was adjusted to spare the larger caliber vessels perfusing the inner retina. Electrophysiologically, a decrease in amplitude of the visual evoked potential is noted. Histologically, alterations in axonal transport are seen. Polymerase chain reactions (rt-PCR) indicate that there are both early RGC-specific, and later retinal gene expression changes in the treated animals. This method replicates many cellular and molecular level changes in a low-cost animal model.

Abstract:

Optic nerve lamina region neural progenitor cells (ONLR-NPCs) are provided. Such cells secrete growth factors and survival factors that can be used in the treatment of optic nerve diseases, such as glaucoma. Also provided are methods of treating or preventing optic nerve diseases, such as glaucoma, using one or more factors secreted by ONLR-NPCs, combinations of factors secreted by ONLR-NPCs, or culture media conditioned by ONLR-NPCs.
