COMPOSITIONS AND METHODS FOR TREATMENT OF NEURAL DISORDERS USING TRANSFORMING GROWTH FACTOR-BETA SUPERFAMILY PROTEINS AND THEIR ANTAGONISTS

摘要

Contemplated compositions and methods employ a TGF-beta superfamily protein or antagonist thereof to treat a neural disorder characterized by an imbalance in differentiated functional sensory and neural cells derived from a sensory/neural progenitor cell. Preferably, GDF-11 and/or antagonists thereof are employed in the treatment of diseases in which visual and/or auditory progenitor cells will provide for a repair mechanism to the disease. Most preferably, GDF-11 is employed as a modulator of competency to increase production of retinal ganglion cells, retinal photoreceptors, retinal amacrine cells, sensory hair and supporting cells of the vestibulocochlear epithelium, and/or neurons and supporting cells of the spiral acoustic ganglion and vestibulo-cochlear (auditory) nerve to which it gives rise.
