Gil JM, Mohapel P, Araujo IM, Popovic N, Li JY, Brundin P and Petersen Å.Neurobiology of Disease 3: 744-751 (2005)AbstractWe investigated whether cell proliferation and neurogenesis are altered in R6/2 transgenic Huntington's disease mice. Using bromodeoxyuridine (BrdU), we found a progressive decrease in the number of proliferating cells in the dentate gyrus of R6/2 mice. This reduction was detec

Petersén Å, Stewénius Y, Björkqvist M and Gisselsson D.BMC Cell Biology 6: 34 (2005)AbstractBACKGROUND: Huntington's disease (HD) is a hereditary neurodegenerative disorder caused by a CAG repeat expansion in the HD gene. The huntingtin protein expressed from HD has an unknown function but is suggested to interact with proteins involved in the cell division machinery. The R6/2 transgenic mouse is

Smith R, Petersén Å, Bates GP, Brundin P and Li JY.Neurobiology of Disease 20: 673-84 (2005)AbstractHuntington's disease (HD) is a hereditary neurodegenerative disorder characterized by progressive psychiatric, cognitive, and motor disturbances. We studied the expression of synaptic vesicle proteins in the R6/1 transgenic mouse model of HD. We observed that the levels of rabphilin 3A, a protein in

Karlsson J, Petersén Å, Gidö G, Wieloch T and Brundin P.Cell Transplantation 14: 301-309 (2005)AbstractAround 80-95% of the immature dopaminergic neurons die when embryonic ventral mesencephalic tissue is transplanted. Cell death occurs both during the preparation of donor tissue and after graft implantation, but the effect of combining successful neuroprotective treatments before and after transp
