13. Regeneração da medula espinhal de ratos adultos após a inoculação de células de Schwann em presença do fator neurotrófico derivado de células Gliais (GDNF). Análise comportamental e celular. / Spinal cord regeneration in adult rats after Schwann cells inoculation in the presence of glial derived neurotrophic factor (GDNF). Behavioral and cellular analyses.
Células de Schwann (CS) cultivadas a partir de nervo ciático de ratos foram enxertadas, associadas ou não ao fator de crescimento derivado de células gliais (GDNF), em ratos adultos submetidos à transecção total da medula espinhal (T11). Análises do comportamento motor do 1º ao 3º mês pós-operatório e do crescimento de fibras nervosas imunorreat

14. Comparison of Blood-Brain Barrier Transport of Glial-Derived Neurotrophic Factor (GDNF) and an IgG-GDNF Fusion Protein in the Rhesus Monkey
The brain drug development of glial-derived neurotrophic factor (GDNF) is prevented by the lack of transport of this protein across the blood-brain barrier (BBB). GDNF transport across the BBB can be made possible by re-engineering the neurotrophin as a fusion protein with a genetically engineered monoclonal antibody (MAb) against the human insulin receptor

15. Cellular localization of GDNF and its GFRalpha1/RET receptor complex in the developing pancreas of cat
Glial cell line-derived neurotrophic factor (GDNF) acts through RET receptor tyrosine kinase and its co-receptor GFRalpha1. In an effort to better understand the possible biological contribution of the GDNF and GFRalpha1/RET complex in pancreatic development, in this study we report the cellular localization of these proteins in the pancreas of domestic cat

16. Glial cell line-derived neurotrophic factor promotes the survival and morphologic differentiation of Purkinje cells.
Glial cell line-derived neurotrophic factor (GDNF) promotes survival of midbrain dopaminergic neurons and motoneurons. Expression of GDNF mRNA in cerebellum raises the possibility that cells within this structure might also respond to GDNF. To examine potential trophic activities of GDNF, dissociated cultures of gestational day 18 rat cerebellum were grown f

17. Clinically Relevant Effects of Convection-Enhanced Delivery of AAV2-GDNF on the Dopaminergic Nigrostriatal Pathway in Aged Rhesus Monkeys
Growth factor therapy for Parkinson's disease offers the prospect of restoration of dopaminergic innervation and/or prevention of neurodegeneration. Safety and efficacy of an adeno-associated virus (AAV2) encoding human glial cell-derived neurotrophic factor (GDNF) was investigated in aged nonhuman primates. Positron emission tomography with 6-[18F]-fluoro-l

18. Glial cell line-derived neurotrophic factor activates the receptor tyrosine kinase RET and promotes kidney morphogenesis.
The receptor tyrosine kinase RET functions during the development of the kidney and the enteric nervous system, yet no ligand has been identified to date. This report demonstrates that the glial cell line-derived neurotrophic factor (GDNF) activates RET, as measured by tyrosine phosphorylation of the intracellular catalytic domain. GDNF also binds RET with a

19. The structure of GFRα1 domain 3 reveals new insights into GDNF binding and RET activation
Glial cell line-derived neurotrophic factor (GDNF) binds to the GDNF family co-receptor α1 (GFRα1) and activates RET receptor tyrosine kinase. GFRα1 has a putative domain structure of three homologous cysteine-rich domains, where domains 2 and 3 make up a central domain responsible for GDNF binding. We report here the 1.8 Å crystal structure of GFRα1 do

20. Egr-1 Is Necessary for Fibroblast Growth Factor-2-induced Transcriptional Activation of the Glial Cell Line-derived Neurotrophic Factor in Murine Astrocytes*
Glial cell line-derived neurotrophic factor (Gdnf) promotes neurite outgrowth and survival of neuronal cells, but its transcriptional regulation is poorly understood. Here, we sought to investigate the mechanism underlying fibroblast growth factor-2 (FGF2) induction of Gdnf expression in astrocytes. We found that FGF2 stimulation of rat astrocytes induced ex

21. Retrograde axonal transport of glial cell line-derived neurotrophic factor in the adult nigrostriatal system suggests a trophic role in the adult.
The recently cloned, distant member of the transforming growth factor beta (TGF-beta) family, glial cell line-derived neurotrophic factor (GDNF), has potent trophic actions on fetal mesencephalic dopamine neurons. GDNF also has protective and restorative activity on adult mesencephalic dopaminergic neurons and potently protects motoneurons from axotomy-induc

22. Activation by GDNF of a transcriptional program repressing neurite growth in dorsal root ganglia
Glial cell line-derived neurotrophic factor (GDNF) promotes the survival of postnatal—but not embryonic—mouse dorsal root ganglion cells in vitro, despite the fact that its receptors are expressed at both ages. To understand this difference, we have performed an oligonucleotide microarray experiment. We found that several hundred genes were regulate

23. Intrastriatal injection of an adenoviral vector expressing glial-cell-line-derived neurotrophic factor prevents dopaminergic neuron degeneration and behavioral impairment in a rat model of Parkinson disease
Glial-cell-line-derived neurotrophic factor (GDNF) is a potent neurotrophic factor for adult nigral dopamine neurons in vivo. GDNF has both protective and restorative effects on the nigro-striatal dopaminergic (DA) system in animal models of Parkinson disease. Appropriate administration of this factor is essential for the success of its clinical application.

24. Midbrain injection of recombinant adeno-associated virus encoding rat glial cell line-derived neurotrophic factor protects nigral neurons in a progressive 6-hydroxydopamine-induced degeneration model of Parkinson’s disease in rats
A recombinant adeno-associated virus (rAAV) vector capable of infecting cells and expressing rat glial cell line-derived neurotrophic factor (rGDNF), a putative central nervous system dopaminergic survival factor, under the control of a potent cytomegalovirus (CMV) immediate/early promoter (AAV-MD-rGDNF) was constructed. Two experiments were performed to eva
