title: Soluble amyloid precursor proteins and secretases as Alzheimer's disease biomarkers.
abstract: Recently revised diagnostic guidelines for Alzheimer's disease (AD) emphasise the use of biomarkers, heralding a paradigm shift towards a more biological definition of the disorder. Currently available biomarkers offer added diagnostic accuracy in certain situations, but their performance in terms of early diagnostic sensitivity and specificity does not fully live up to the desired standards. One feasible approach to improve the diagnostic and prognostic performance of AD biomarkers is to measure upstream events of amyloid precursor protein (APP) processing, which are at the core of the initial phase of AD pathogenesis. Here we review evidence on the APP processing enzymes and their cleavage products and discuss possible applications and limitations in their use as AD biomarkers.
