Petersén Å, Hansson O and Brundin P.In Swedish. Läkartidningen 50: 5756-5761 (2001)AbstractHuntingtons sjukdom är en av flera kända neurologiska sjukdomar som beror på en expanderad CAG-repetition. Symtomen karakteriseras av motoriska, psykiska och kognitiva störningar. Muterat huntingtin uttrycks i hela kroppen, och neurodegeneration och aggregering av det muterade proteinet huntingtin sker i bas

Petersén Å, Castilho RF, Hansson O, Wieloch T and Brundin P.Brain Research 857: 20-29 (2000)AbstractDisruption of intracellular calcium homeostasis is thought to play a role in neurodegenerative disorders such as Huntington's disease (HD). To study different aspects of putative pathogenic mechanisms in HD, we aimed to establish an in vitro model of calcium-induced toxicity in striatal neurons. The

Mundt-Petersén U, Petersén Å, Emgård M, Dunnett SB and Brundin P.Experimental Neurology 164:112-120 (2000)AbstractIn transplants of embryonic striatal cells placed into the excitotoxically lesioned rat striatum (a model of Huntington's disease), as many as 60 to 90% of the grafted cells are believed to die. Caspase activation is part of a cascade of events that can lead to apoptosis. We investigat

Petersén Å, Hansson O, Emgård M and Brundin P.Cell Transplantation 9: 577-584 (2000)AbstractTransplantation of embryonic ventral mesencephalon is a potential therapy for patients with Parkinson's disease. As only around 5-10% of embryonic dopaminergic neurons survive grafting into the adult striatum, it is considered necessary to use multiple donor embryos. To increase the survival of the grafted

Brundin P, Karlsson J, Emgård M, Kaminski Schierle GS, Hansson O, Petersén Å and Castilho RF.Cell Transplantation 9: 179-195 (2000)AbstractNeural transplantation is developing into a therapeutic alternative in Parkinson's disease. A major limiting factor is that only 3-20% of grafted dopamine neurons survive the procedure. Recent advances regarding how and when the neurons die indicate that events

Petersén Å, Emgård M and Brundin P.Brain Research Bulletin 50: 275-281 (1999)AbstractThe survival of grafted embryonic striatal tissue, dissected from the lateral ganglionic eminence, depends on the status of the host striatum. We found significantly larger volumes of surviving graft tissue and of striatal-like tissue (P-zone) within the graft, when the host striatum had been subjected to an excit

Petersén Å and Brundin P.Experimental Neurology 160: 402-412 (1999)AbstractCiliary neurotrophic factor (CNTF) has a protective effect on the striatum in animal models of Huntington's disease. However, the mechanism through which it exerts its effect is not clear. In this study, we show that there is a concentration-dependent direct protective effect of CNTF against N-methyl-D-aspartate-mediated ex

Petersén Å, Mani K and Brundin P.Experimental Neurology 157: 1-18 (1999)AbstractWe review recent advances regarding the pathogenesis of Huntington's disease (HD). This genetic neurodegenerative disorder is caused by an expanded CAG repeat in a gene coding for a protein, with unknown function, called huntingtin. There is selective death of striatal and cortical neurons. Both in patients and a trans
