Alzheimer's disease (AD) is a disorder of two pathologies: amyloid plaques, the core of which is a peptide derived from the amyloid precursor protein (APP), and neurofibrillary tangles composed of highly phosphorylated tau. Protein kinase C (PKC) is known to increase non-amyloidogenic alpha-secretase cleavage of APP, producing secreted APP (sAPPalpha), and(More)
The expression of familial Alzheimer's disease mutants of presenilin-1 (PS1) proteins has been observed to induce cell death in cellular systems. To investigate how this phenomenon might be associated to alterations of the microtubule network, we have studied the effect of wild-type and mutant (C263R, P264L and delta9) PS1 proteins expression on the(More)
