Grafts of fetal dopamine neurons survive and improve motor function in Parkinson's disease

Neural transplantation can restore striatal dopaminergic neurotransmission in animal models of Parkinson's disease. It has now been shown that mesencephalic dopamine neurons, obtained from human fetuses of 8 to 9 weeks gestational age, can survive in the human brain and produce marked and sustained symptomatic relief in a patient severely affected with idiopathic Parkinson's disease. The grafts, w

Human fetal dopamine neurons grafted into the striatum in two patients with severe Parkinson's disease. A detailed account of methodology and a 6-month follow-up

By using stereotaxic surgical techniques, ventral mesencephalic tissues from aborted human fetuses of 8 to 10 weeks' gestational age were implanted unilaterally into the striata in two patients with advanced Parkinson's disease. The patients were treated with a cyclosporine, azathioprine, and steroid regimen to minimize the risk for graft rejection. They were examined for 6 months preoperatively a

Survival and immunogenicity of dissociated allogeneic fetal neural dopamine-rich grafts when implanted into the brains of adult mice

The survival of grafts of dissociated allogeneic fetal neural dopamine (DA) rich tissue in the striatum has been studied after transplantation between inbred strains of mice differing at defined immunogenetical loci between donor and recipient. Six to 7 weeks and 15 weeks after grafting, surviving grafted DA neurons were found in the brains of all the recipients, albeit with a large variation in n

Intracerebral xenografts of dopamine neurons : the role of immunosuppression and the blood-brain barrier

Fetal mesencephalic mouse tissue, rich in dopamine neurons, was xenografted as a dissociated cell suspension into the striatum of rats with unilateral 6-hydroxydopamine induced lesions of the mesostriatal pathway. The rats were either assigned to a 10-day, 21-day or 42-day Cyclosporin A (CyA) immunosuppression scheme, or given no immunosuppression. The functional effects of the grafts were followe

Immune response in deep cervical lymph nodes and spleen in the mouse after antigen deposition in different intracerebral sites

Brain interstitial and cerebrospinal fluid drainage into the lymphatics was studied by injections of 5 microliters of packed sheep red blood cells (SRBC) injected into the caudate nucleus, the occipital lobe, and the lateral ventricle of the brain in mice. The number of plaque-forming cells (PFC) was determined in the deep cervical lymph nodes, the axillary lymph nodes, and the spleen, and the num

Human fetal basal forebrain neurons grafted to the denervated rat hippocampus produce an organotypic cholinergic reinnervation pattern

The septal/diagonal band (SDB) area, obtained from a 9- to 10-week-old aborted human fetus, was grafted to the hippocampal formation of adult, immunosuppressed rats subjected to an aspirative lesion of the fimbria-fornix. Nineteen weeks after transplantation, microscopical analysis revealed large, partly acetylcholinesterase (AChE)-positive grafts in the hippocampus in 3 of the 5 recipients. The A

Human fetal dopamine neurons grafted in a rat model of Parkinson's disease : immunological aspects, spontaneous and drug-induced behaviour, and dopamine release

We have used a rat model of Parkinson's disease (PD) to address issues of importance for a future clinical application of dopamine (DA) neuron grafting in patients with PD. Human mesencephalic DA neurons, obtained from 6.5-8 week old fetuses, were found to survive intracerebral cell suspension xenografting to the striatum of rats immunosuppressed with Cyclosporin A. The grafts produced an extensiv

Knowing and Seeing the Combatant. War, Counterinsurgency and Targeting in International Law

Knowing and Seeing the Combatant investigates how does the US counterinsurgent forces make distinction between civilians and combatants during targeting practices? This dissertation is specifically focused on the visual dynamics of the contemporary targeting and as such argues that the insurgent's withdrawal from the obligation of visual self-identification as targets by not wearing military unifoKnowing and Seeing the Combatant investigates how does the US counterinsurgent forces make distinction between civilians and combatants during targeting practices?
