Abstract: 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.

Abstract: Disclosed are novel proteins, referred to as truncated glial cell line-derived neurotrophic factor (truncated GDNF) proteins, that promote dopamine uptake by dopaminergic cells and promote the survival of nerve cells. Also disclosed are processes for obtaining the truncated GDNF proteins by recombinant genetic engineering techniques.
Abstract: 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.
