Glial cells play a key role in the function of dopamine (DA) neurons and regulate their differentiation, morphology, physiological and pharmacological properties, survival, and resistance to different models of DA lesion. Several studies suggest that glial cells may be important in the pathogenesis of Parkinson's disease (PD), a common neurodegenerative(More)
Intracellular glutathione (GSH) levels determine whether nitric oxide (NO) is neurotrophic for dopamine neurons or triggers a cell death cascade in primary midbrain cultures. We have investigated herein the role of the extracellular-signal regulated protein kinase (ERK) 1/2 pathway in this GSH switching effect. The short-lived NO donor DEA/NO induces a(More)
INTRODUCTION Glia conditioned medium (GCM) is neurotrophic for dopaminergic (DA) neurons and protects against MPP+ toxicity in vitro. We present the data from the first study in vivo of the effects of GCM. MATERIAL AND METHODS The restorative effects were examined in rats with lesions produced by 6-hydroxy-dopamine (6-OH-DA) in the medial longitudinal(More)
Huntington's disease is a neurodegenerative disorder caused by an expansion of CAG repeats in the huntingtin gene which produces widespread neuronal and glial pathology. We here investigated the possible therapeutic role of glia or glial products in Huntington's disease using striatal glial conditioned medium (GCM) from fetus mice (E16) continuously infused(More)
