Glial cell line-derived neurotrophic factor (GDNF) is a widely distributed member of the transforming growth factor-beta superfamily and a potent neurotrophic molecule for several neuron populations in the peripheral and central nervous system. We show here that adrenal medullary chromaffin cells synthesize GDNF mRNA and contain immunoreactive GDNF protein.(More)
Molecular mechanisms underlying the generation of distinct cell phenotypes is a key issue in developmental biology. A major paradigm of determination of neural cell fate concerns the development of sympathetic neurones and neuroendocrine chromaffin cells from a common sympathoadrenal (SA) progenitor cell. Two decades of in vitro experiments have suggested(More)
BACKGROUND Gelastic epilepsy due to hypothalamic hamartomas is usually a severe condition encompassing both epileptic seizures and an epileptic encephalopathy associated with behavioral and cognitive impairments. Here we report the effects of interstitial radiosurgery in the treatment of this generally pharmacoresistant epilepsy syndrome. METHODS(More)
