摘要:
A novel neurotrophic factor referred to as glial cell line-derived neurotrophic factor (GDNF) has been identified and isolated from serum free growth conditioned medium of B49 glioblastoma cells. Rat and human genes encoding GDNF have been cloned and sequenced. A gene encoding GDNF has been subcloned into a vector and the vector has been used to transform a host cell in order to produce biologically active GDNF in a recombinant DNA process. Antibodies to GDNF are disclosed, as well as methods for identifying members of the GDNF family of neurotrophic factors.

摘要:
A novel neurotrophic factor referred to as glial cell line-derived neurotrophic factor (GDNF) has been identified. Genes encoding GDNF have been cloned and sequenced. Methods and devices are disclosed for the delivery of GDNF using either an implantable cell which expresses human GDNF or a biocompatible semipermeable membrane containing genetically engineered cells which express and secrete the neurotrophic factor.

A gene encoding GDNF has been subcloned into a vector, and the vector has been used to transform a host cell in order to produce biologically active GDNF in a recombinant DNA process. An implantable device containing recombinant GDNF secreting cells encapsulated in a semipermeable membrane may be used to treat nerve damage in patients suffering from disorders such as Parkinson's disease.
摘要:
This invention describes processes for producing mature human members of the NGF/BDNF family of neurotrophic proteins that are fully biologically active. In addition, the gene encoding human BDNF and processes for obtaining the same are disclosed.A previously-unreported member of the NGF/BDNF family of neurotrophic proteins, NGF-3, has been identified and a portion of the gene encoding for the NGF-3 has been described. Processes for identifying additional previously unreported members of the NGF/BDNF family are also described.
摘要:
A process for the production of biologically active recombinant neurotrophic factor from the NGF/BDNF family is described. The process is comprised of a) constructing a synthetic neurotrophic factor gene suitable for expression in a bacterial expression system; b) the synthetic neurotrophic factor gene is expressed in a bacterial expression system; c) the neurotrophic factor is solubilized and sulfonylated; d) sulfonylated neurotrophic factor is allowed to refold in the presence of polyethylene glycol and urea; and e) biologically active neurotrophic factor is isolated and purified.
