1. A method of improving nerve growth into a partial transection of a spinal cord, comprising:
- introducing into the transection NGF and a non-cellular gap filling agent that includes a therapeutically effective amount of a benzoquinone ansamycin that binds to a polypeptide component of a steroid receptor complex other than a steroid binding portion of the complex, wherein the NGF and benzoquinone ansamycin are present in a therapeutically sufficient amount to interfere with association or promote dissociation of hsp90 from the complex, and promote nerve growth into the spinal cord.

Abstract
FK506 and geldanamycin promote nerve regeneration by a common mechanism that involves the binding of these compounds to polypeptide components of steroid receptor-complexes other than the steroid hormone binding portion of the complex (FKBP52 and hsp90, respectively). These and other agents cause hsp90 dissociation from steroid receptor complexes or block association of hsp90 with steroid receptor complexes.

2. A method of promoting nerve growth a mammal having a partially transected spinal cord, the method comprising:
administering to the mammal a pharmaceutical composition comprising a nerve growth stimulating amount of a non-FKBP12-binding agent that binds to a polypeptide component of a steroid receptor complex other than a steroid hormone binding portion of the complex wherein the agent interferes with association or promotes dissociation of hsp90 with the complex and promotes nerve growth, thereby promoting nerve growth. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 30)

15. A method of promoting nerve repair in a mammal having a spinal cord injury, the method comprising:
administering to the mammal a pharmaceutical composition comprising a nerve repair stimulating amount of an agent, other than FK506, that binds to a polypeptide component of a steroid receptor complex other than a steroid hormone binding portion of the complex, and which promotes hsp90 dissociation or inhibits hsp90 association with the complex, and promotes repair of the injury, wherein the spinal cord injury is a partial transection. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
