Apolipoprotein E epsilon 4 is associated with an increased vulnerability to cell death in Alzheimer’s disease
The presumption to suffer from Alzheimer’s disease (AD) accelerates with aging. One important risk factor seems to be the isoform epsilon 4 of the apolipoprotein E gene (Apo ɛ4), which increases the risk to de...

Membrane Disordering Effects of β-Amyloid Peptides
The interaction of Aβ with synaptosomal plasma membranes decreases membrane fluidity. Using model membrane/Iiposome systems the interaction of Aβ with specific lipids (e.g. phospholipids, gangliosides, cholestero...

Impact of gender on upregulation of antioxidant defence mechanisms in Alzheimer’s disease brain
Since oxidative stress plays an important role in the pathogenesis of Alzheimer’s disease (AD) and since the age-adjusted incidence of AD is higher in females than males, we examined a possible influence of ge...
