Apolipoprotein E-deficient mice provide a useful system for studying the role of apolipoprotein E (apoE) in the function of distinct neuronal systems. In the present study we focused on the cholinergic system of these mice. This was pursued by measurements of specific biochemical, physiological and cognitive parameters. Morris Water Maze tasks revealed(More)
It has been suggested that the deleterious effects of the allele E4 of apolipoprotein E (apoE) in Alzheimer's disease (AD) are related to its inability to interact with the microtubule associated protein tau and to thereby prevent its hyperphosphorylation. In the present study we investigated the effects of apoE on tau phosphorylation by immunoblot analysis(More)
Apolipoprotein-E-deficient mice provide a useful model system for studying the role of apolipoprotein E (apoE) in brain function. In the present study, we characterized the cholinergic function of these mice and the extent of phosphorylation of their cytoskeletal protein tau. Morris water maze tasks revealed deficits in working memory that were accompanied(More)
Apolipoprotein E (apoE)-deficient mice have memory deficits that are associated with synaptic loss of basal forebrain cholinergic projections and with hyperphosphorylation of distinct epitopes of the microtubule-associated protein tau. Furthermore, treatment of apoE-deficient mice with the M1 selective agonist(More)
