Glial cell line–derived neurotrophic factor (GDNF) family ligand (GFL) consists of GDNF, neurturin (NRTN), artemin (ARTN), and persephin (PSPN). These GFLs signal through a receptor complex consisting coreceptor (GFRα1–4) as binding component, which has no intracellular domain is anchored to the plasma membrane with glycosylphosphatidylinositol, transmembrane RET (rearranged during transfection...
Abstract Electrospun fibrous scaffolds capable of providing dual growth factor delivery in a controlled manner have distinctive advantages for tissue engineering. In this study, we investigated the formation, structure, and characteristics/properties bicomponent glial cell line-derived neurotrophic (GDNF) nerve (NGF) peripheral regeneration. GDNF NGF were incorporated into core-shell structured...
glial cell line-derived neurotrophic factor (gdnf) plays important roles not only for the differentiation of neurons during normal development but also for the survival and recovery of many populations of mature neurons. the effect of traumatic brain injury (tbi) on the expression of gdnf is currently unknown. to determine if there is alteration in gdnf after tbi we examined the effect of contr...
ترانسفکت کردن سلول های استرومایی مغز استخوان با وکتور حامل ژن فاکتور نوروتروفیک مشتق از رده ی سلولی گلیال(gdnf) و ارزیابی بیان آن در محیط in vitro مقدمه : فاکتور نوروتروفیک مشتق از رده ی سلولی گلیال (gdnf) از مهم ترین پروتئین ها در رشد و ترمیم سیستم عصبی است. هر گونه نقص در تولید و ترشح این پروتئین موجب اختلالات مختلفی در بازسازی سلول ها در بیماری های مخرب سیتم عصبی می شود.از گزینه های درمانی ...
Degeneration of nigrostriatal dopaminergic system is the principal lesion in Parkinson's disease. Because glial cell line-derived neurotrophic factor (GDNF) promotes survival of dopamine neurons in vitro and in vivo, intracranial delivery of GDNF has been attempted for Parkinson's disease treatment but with variable success. For improving GDNF-based therapies, knowledge on physiological role of...
Glial cell line-derived neurotrophic factor (GDNF) is released by glioma cells and promotes tumor growth. We have previously found that GDNF from the a chemoattractant for microglial cells, immune of central nervous system. Here we show increases matrix metalloproteinase (MMP) 9 MMP14 expression in cultured mixed sexes neonatal mice. The GDNF-induced MMP9 upregulation mediated family receptor a...
Because of discrepancies in previous reports regarding the role of glial cell line-derived neurotrophic factor (GDNF) in motoneuron (MN) development and survival, we have reexamined MNs in GDNF-deficient mice and in mice exposed to increased GDNF after in utero treatment or in transgenic animals overexpressing GDNF under the control of the muscle-specific promoter myogenin (myo-GDNF). With the ...
Glial cell line-derived neurotrophic factor (GDNF) was encapsulated into liposomes in order to protect it from enzyme degradation in vivo and promote its permeability across the blood-brain barrier (BBB). In this study, GDNF conventional liposomes (GDNF-L) and GDNF target sterically stabilized liposomes (GDNF-SSL-T) were prepared. The average size of liposomes was below 90 nm. A primary model o...
Endocrine and neuronal cells have highly developed secretion mechanisms, and the secretion can be either constitutive or regulated by physiological stimuli. In the constitutive pathway, intracellular transport vesicles undergo immediate fusion reactions after arrival at the target. In regulated secretion, vesicles accumulate near the target membrane until triggered to fuse, typically by a local...
BACKGROUND & AIMS Absence of glial cell line-derived neurotrophic factor (GDNF) leads to intestinal aganglionosis. We recently demonstrated that patients with diverticular disease (DD) exhibit hypoganglionosis suggesting neurotrophic factor deprivation. Thus, we screened mRNA expression pattern of the GDNF system in DD and examined the effects of GDNF on cultured enteric neurons. METHODS Colo...
